It has been 114 years since Rudolph Diesel applied for a patent for his new improved engine. It was hoped to replace the gasoline engine but as we can all see that this has not happened. The gasoline engine having just been invented in 1876 was still considered inefficient in fuel consumption and power. An evaluation of each engine’s performance tells a story that is difficult to reconcile with the way things have shaken out in the beginning of the 21st Century. The invention of the Diesel offered the world a far more efficient and effective fuel based engine. It actually provides more horsepower per gallon or liter than a gasoline. This is why diesel engines power our large earth moving equipment, trucks, marine engines, low mileage
cars and now aircraft.
The diesel is a combustion injection engine. Unlike the gasoline engine, air is compressed first and then the fuel is injected into it. The compressed air is hot enough to ignite the diesel fuel without the use of a sparkplug. Diesel engines developed out of the earlier work surrounding two engines; the original diesel design and the solid injection system of Herbert Akroyd Stuart created in his hot bulb engine. This means that the upward stroke of the diesel engine compresses the air to where its’ temperature is between 1300-1650° F. When the piston has reached the top of its’ upward stroke, diesel fuel is then injected, combustion occurs, pressure increases and pushes the cylinder downwards. This motion is transmitted by means of the connecting rods to the crankshaft which itself turns thus transmitting rotating power to a drive shaft which powers ships, cars, generators, aircraft and even motorcycles.
During cold weather, diesel fuel thickens when the wax crystallizes. It becomes a gel and the fuel injection will not easily work. Technological advances have made this a problem of the past. The fuel lines and fuel filter can be pre-warmed, others use a glow plug in the combustion chamber to pre-heat its’ walls, some use resistive heaters in the intake manifold to warm air taken into the combustion chambers and engine block heaters are used in areas like Kansas or Nebraska when automobiles are left in the cold overnight.
Diesel engine speed used to be controlled by governing the rate of fuel through a gear system. Today the use of electronically controlled engines ECM (electronic control module) allows diesel engines to adjust their timing to start according to the environmental conditions of heat and cold, regulate the engine speed in terms of RPM (revolutions per minute) and maintain fuel economy.
Diesel engines may not have beaten its’ chief contender, the gasoline engine, but it has kept ahead in terms of heavy machine and naval engines. It has recently performed outstandingly in the area of remotely piloted vehicle engines, set amazing land speed records for racecars and motorcycles. The diesel engine has improved amazingly in the past 114 years. The use of electronics has given all engines abilities of fuel conservation unheard of in past years. This makes the diesel engine a real budget-winning contender. This year the new 2006, Volkswagen diesel won fourth place in the best mileage evaluation according to http://www.fueleconomy.gov. Diesels may prove to be the green vehicle engine of choice in the future since they have very little carbon monoxide emissions. Catalytic converters and diesel particulate air filters have made diesel engines free from particulate, nitrogen and sulfur oxides. Diesel engines may prove to be the easiest solution to greenhouse gases.

The diesel engine is fast becoming on of the more economical choices for individuals. With the rising costs of fuels, it is seen that diesel is still one of the more affordable options. It in the best has generated a reputation for being very much a major source of pollution but in recent times has been cleaned up to a great extent.
The biggest advantage of the diesel engine is seen in the fact that the fuel is much more economical. The diesel engine gives a lot more than the gasoline engine for much reduced costs. There is an approximate advantage of using diesel of as much as 30% at times. There is less fuel consumed for the same task and you therefore do not have to refill your tank as often.
The reason many persons do not opt for the diesel engine is in fact the initial start up costs of installing such an engine. The extra costs are quite high for the engine and its installation. If you however look into the savings overall the diesel engine will in fact be the more economical choice.
It is seen too that the vehicle that is installed with a diesel engine will retain more value than the gasoline engine. This is due to there being a demand for vehicles that are fuel efficient on the market as the cost of fuel continues to rise. The diesel engine vehicles also tend to stay on the road longer. If properly maintained these will outlast the typical gasoline engine.
It can also be seen that the diesel engine will give a different drive from a gasoline engine. The vehicle running on a diesel engine will have more of a zip too it. The vehicles will also have more power for tasks such as towing as the diesel engine can handle more load.
There is also another downfall associated with the diesel engine. This is the fact that it is much noisier when compared to the gasoline engine. This noise level is however no where as loud as the past and is in fact quite bearable to users. In fact most of the typical drivers on the road will not be able to tell the difference between a diesel engine and a gasoline engine.
Emissions continue to be a cause for concern for the environmentally conscious. It is true that the diesel engine has come a long way from times gone by in terms of emissions but it is still dirtier than the gasoline engine. There is more visible pollution from the diesel engine and this is due to the fact that the diesel engine will throw out more particulates from the exhaust tailpipe as well as more nitrogen oxides. There is however less carbon dioxide pollution. This is a tradeoff but it is the dilemma that many persons face when choosing between the gasoline and the diesel engines.
One of the other concerns when dealing with the diesel engine is the fuel availability. The diesel fuel is commonly found at truck stops on highways bit is not as common in neighborhood service stations. It is vital that consideration be made of where you will source fuel for a diesel engine. It is also seen that there are not that many options when purchasing a diesel engine
car so the choices are limited.

And the US automotive industry is in dire straits. It did not learn from the 1973 energy crisis. It did not learn from the Chrysler experience. It did not learn from Toyota. It continued to depend on old, worn out concepts and on CEO’s that are kept in their positions by nepotism and by boards that do not understand the automotive business.
In a joint effort the Big Three are asking the US government for a $25 billion loan. They argue that government demands for increased fuel efficiency are too expensive to implement and require huge amounts of capital for retooling.
Let’s assume for the moment that the argument has some merit. But how can companies with worldwide manufacturing facilities fail to notice the steady increase in fuel prices and not see the warning signs hoisted by governments across the world that want to limit greenhouse gas emissions and fossil fuel consumption. This neglect is inexcusable. Efforts of US and European governments to limit fuel consumption are misdirected, counterproductive, and coercive. A comprehensive analysis quickly reveals that we must indeed limit and eventually halt greenhouse gas emissions.
OPEC countries will continue their unstoppable increases of petroleum prices. Electric cars, CNG powered cars, and hydrogen powered cars cannot stop carbon dioxide emissions perceptibly and will not make our country independent of OPEC imports. Automotive companies are critically dependent on the fickle and changing preferences of national and international markets.
Industrial companies that follow political hype will be punished sooner or later. Governments are incapable of designing automobiles for the market place. The world is relegated to using automobiles, trucks, trains, ships, and airplanes for the next century and will have to power most of them with liquid transportation fuels. We may be able to use less of them, we will be able to reduce energy consumption, we can use other forms of energy for some transportation, and we can produce petroleum substitutes from biomass. We can even produce biomass without competing with critically important food crops.
In order to minimize fuel consumption quickly, the auto industry is forced to deal with performance features. American drivers cannot avoid covering much longer distances than European or Japanese drivers. American drivers have less access to public transportation, have larger families, and drive on different types of roads. Automotive companies must listen to their customers.
Toyota and Honda have been listening most successfully. American and foreign car companies have developed a wide range of comfortable cars with a wide variety of utilitarian and luxury features. Sportive cars and SUV’s are attracting large numbers of buyers. All cars offer a wide selection of comfort and entertainment features. One major car component has received only peripheral attention; it is the much maligned internal combustion engine.
Many modern internal combustion engines are marvels of engineering. Materials, manufacturing processes, and especially peripheral components have progressed to unprecedented levels of performance and longevity. There is a last frontier that has escaped deserved attention. This is the highly energy efficient combustion engine. This is the type of engine that the automotive engine needs to develop, this is the engine that legislators should make mandatory.
This is the engine that we need to use for at least one more century. Long term the automotive industry has to develop an entirely new, advanced, internal combustion engine! Average energy efficiency of the worlds inventory of combustion engines is somewhere in the lower mid-twenties. Energy efficiency cannot grow indefinitely. When approaching the 50% efficiency mark, it will be difficult and very expensive to increase efficiency by a single percent. Advanced automotive engines are operating in the mid-thirties.
Large stationary engines are breaking the 45% mark. Large engines on trains and ships are getting above 40%. Looking at the total world inventory, we may still have a chance to nearly double energy efficiency and to cut energy consumption of present inventory in half. We cannot reach this goal by legislating fuel consumption of cars only. We can achieve optimum energy efficiency only by reengineering the processes taking place within and around the internal combustion space.
We know that higher compression ratios will increase energy efficiency, we know how to produce high octane fuel, we know why Diesel engines are more efficient, we know how to minimize formation of pollutants. The automotive industry has developed a huge selection of sophisticated electronic components for single cylinder fuel injection, for precise controls of valve motion and ignition timing, and for reclaiming waste energy at the exhaust.
No company seems to have found the nerve to get a jump on the competition and develop the successor to the two more than century old engine concepts; the Otto and the Diesel engines. If the US government decides to extend a $25 billion loan to the automotive industry, it should attach a few conditions. The loan needs to be secured and must take precedent over shareholder equity. The loan should stipulate that the salaries of top management are tethered to salaries of other top CEO’s like that of the US President.
The obscene bonuses of yesterday should be paid only after a waiting period of at least five years; in which previously agreed upon management objectives must have been met or exceeded. We must stop the prevalent looting of cash from US manufacturing companies by unscrupulous investors. These investors do not contribute anything of lasting value. They are excessively rewarded for ruining once healthy companies. We cannot continue to let a selected few impoverish the many and ruin our country irreparably.

Such reusable air filter lasts longer for your car and keeps on keeping the performance uncastrated.
Performance Chips: Most brand new cars are operated by computer chips and those chips terminate the torque and h.p. to be displaced. Recalibrations or performance chips are highly in use these days to improve automotive performance. Installing performance chips will help you amount the torque and h.p. of your vehicle significantly.
Performance Exhaust Systems: This is another way to take care of automotive performance. The catalyst back exhaust system is a extraordinary way to free cornered force and loose the h.p.. This automotive system incorporates larger width exhaust pipe and low restriction muffler tips into your vehicle which lowers the exhaust back pressure. Another favorable gain of this system is a sound impression of your vehicle which is really awesome.
Cold Air Intake: This upgrade system is under the bonnet mod which is utilised to reduce the temperature of air entering the car to amount power of engine. This installation enhances your engine looks besides increasing its power. This object too makes the sound of engine appealing.

For the legendary Lamborghini sports car stable of fantastic ultra high performance and styled vehicles it all started with ordinary Fiat automobiles and tractors.
Mr. Lamborghini – fully named – Mr. Ferruccio Lamborghini got his start with Fiats and then went on to a large successful manufacturing concern that grew from a small manufacturing shop into a major producer of tractors. However at a certain point in every person’s life they search out to complete what their real passion is. In the case of Lamborghini was finely styled and crafted motor cars. At 60 years of age, an established manufacturer of agricultural tractors – Mr. Lamborghini – decided that he could a better job of building a high end, beautifully styled, performance racing automobiles than either of the two dominant Italian auto firms of that auto industry sector – Ferrari and Maserati.
The first product out of the door had a chassis that was multi-tubular; the engine was front mounted sporting a 3.5 liter 12 cylinder V-12 engine. The V-12 engine itself was fitted with six Weber carburetors and ran four overhead camshafts. It all clocked at 360 ultra smooth horsepower with the transmission drive being through five speed stick shift. Suspension involved a coil and wishbone independent suspension set up. In one word it was wow – both in terms of performance of the hop as well as the automotive styling.
Although the styling of those early Lamborghini models may be considered standard Italian sports car design – designs which have worked their way into the so called standard “sport scar designs “and “sport scar flair”, at the time it was new and innovative and for the most part if was twenty five years ahead of anything produced in the good old U.S.A. . The one American sports car which might be considered an exception to that point was the Chevrolet Corvette. For years to come nothing else really matched or was similar to the clean aerodynamic lines and styling of the early Lamborghini classic autos.
Even then Lamborghini had such innovative products the establishment and reputation of the Lamborghini product line was no easy road to hoe. Although the first cars were produced in 1963 it was not for two years later – at the Turin Motor Show that the car began to attract solid interest and for the reputation of the car and its studio to grow and begin to become accepted for what it should be.
The first real product of record for Lamborghini was what was marketed as Miura T 400 model automobile. Its first year of manufacture was the 1966 model year. The basic layout and design of the Miura T 400 was a mid-engined coupe with a slightly larger version of the overhead cam engine – the classic V-12 laid out transversely behind the two seats of the car. The rear wheels were then driven by this engine through” spurs gears”. Interestingly the gear boxes and rear axles were Lamborghini products all by themselves -so they shared a lineage that was unique and not the same as any other of the competitor’s models.
What was performance of this little cat? The V-12 engine could pour out a total of 385 barrel horsepower. Top speed of this little coupe was over 180 miles per hour. It could more than carry its weight with the local Italian contenders – even the famed Ferraris.
If the was one complaint from drivers or riders it was of noise levels in the car’s cockpit. It can be said that this was the price to be paid for success or in this case speed and performance. If you cannot stand the heat don’t stay in the kitchen. Certainly the buyers of Lamborghini fine motor cars who bought the product and established the revered name for its performance and advanced styling and forgo this small shortcoming or foible as the car as an assumed fact – even a luxury.
The next model in the Lamborghini stable was introduced approximately two years later. The entire life of the production run of the popular Miura model was nine years – with two cars being produced a week ( a production figure of only 100 or so cars a year). The name of this vehicle was the Espada. For the new Lamborghini model, the Espada, Lamborghini went back to a more standard front engine layout. Perhaps this was in response to concerns over noise levels in the cockpit of the Miura and the need to produce a more “standard” or “civilized “vehicle product. No one really knows what went on in the mind of the genius Ferruccio Lamborghini. However what was retained for sure were the Lamborghini basics – the four liter V-12 massive highly tuned engine with whizzy overhead cams and multiple choke carburetors all putting out massive automotive performance and handling.
In the end it can be said that the Lamborghini automotive and automotive styling and performance legends are more than unique and reek of power, thrust and acceleration.
