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.

In the world of auto mechanics an engine swap is just about the biggest job you can undertake. No matter what kind of car you drive its inevitable that the engine could possibly fail. If your car has very high miles its almost a given. You have a few options if that happens. You can sell your car as is, pay to have a new engine installed, or take the liberty of doing it yourself. The level of difficulty that changing an engine has changed with automotive technology. The newer and more advanced your car is the more technology goes into making the engine work. Back when carburetors were used things were much simpler. Changing an engine basically consisted of disconnecting a few wires, motor mounts, trans mission, radiator hoses, and throttle linkage. The same basic process still applies on modern engines but it just involves a lot more work. There a many more connections, hoses and cables that need removed.

When changing your own engine the basic challenge is to disconnect everything and put it back exactly how you started. As I mentioned in the previous paragraph the age of your car is where the complexity issue comes in to play. Basically it is the same process but, the older the car the easier the process. When undertaking a job of this size you should be sure to have all the needed tools to perform the job properly. Not having the correct tools can lead to damage of parts and a lot of lost time. You can spend more time working rather than looking for the correct tool to perform the task. Overall spending a little money on the right tools can save you a lot time and money in the future. Depending on where you vehicle was made will determine whether you will need metric or standard tools. European and Asian will require all metric tools and almost all domestics will take standard.

When selecting an engine you must be very careful and be completely sure that you have chosen the correct engine. Thats not something you want to find out when installing the new engine. Again, as automotive technology has advanced so have engines. In the past if you could make an engine fit in the engine compartment you could make it work. The electronics of modern cars makes this virtually impossible without major modification. Fuel injected cars are much more complex. They involve electronic controls rather than manual controls. Basically the most important thing to remember is: Do your research. You need to know the exact model, year, and engine displacement of your vehicle.

Once you have obtained a new or used engine the real work begins. Prior to starting you need to purchase all engine fluids to replace once you have completed. Most cars will require the hood to be removed for full access to the engine area. You should mark the bolt position on the hood hinges to make for easy alignment when reinstalling. Drain all your engine fluids, drain coolant, disconnect all wiring, throttle linkages, fuel lines, and cooling hoses. Be sure to remember what you removed and where it came from. Its a good idea to take photos of all areas of the engine compartment. This will give you a good reference for reassembly. Next, remove the bolts from the motor mounts, transmission and exhaust. Once you have made certain that nothing is still attached to the engine you can begin slowly lifting the engine out. Obviously this will require an engine lift and chains. Carefully remove the engine from the engine bay and set it aside.

The installation process is basically a reverse of the removal. Carefully set the engine back into the engine compartment and bolt up the motor mounts, transmission and exhaust. Its a good idea to replace the motor mounts, belts, hoses, plugs and wires in this process. This just allows for much easier access to all of these components. This could save you a lot of time and work in the future. Reconnect the wires, hoses, and linkages. Once everything is reconnected you can move on to replacing all of the fluids. Your coolant will require a complete refill due to to the lack of coolant in the new engine. Once your fluids are replaced check for leaks and double check for loose connections. After everything has been checked and secured your ready to start it up. New engines will require a break in period. This will be detailed in your new engines documentation. You should test drive your car and watch for anything abnormal. When finished test driving check all of your fluids and top them off in needed. If everything goes as planned you should be ready to hit the road again.

This article is not really meant to be a complete guide. Its basically an outline on what is involved in the process. If you are planning on changing your engine yourself you should know what to expect. Its not a process that you want to get partly finished and give up. It is a pretty difficult task that takes time and effort. Its impossible to create one thorough guide due to the fact that almost all auto makes are unique. A good tip is to purchase a complete repair manual for your make of vehicle. There are some great publications for every make of car. You get what you pay for when you by a repair manual. The higher the price, the more thorough manual you will get. You should have a decent amount of mechanical knowledge before attempting this job. If you have any doubts you should probably leave it up to a professional mechanic. Overall be sure that you have the will power, knowledge, tools, and time before taking on a job like this. If you enjoy mechanics this will be a rewarding and educational process.
