What are Hybrid Automotives?

November 5th, 2009 by engineering magazines

The vehicles that use two power sources in conjunction with one another are called hybrid automotives or hybrid vehicles. The history of hybrid power technology is very old. It dates back to the time when diesel electric submarines were first used.

The idea is quite simple, use two power sources to increase the overall efficiency.

Now the question arises that why it was needed. The answer is simple, it was realized that an average person would not be able to afford gasoline in the near future. CO2 emissions will also increase similarly an average person does not require a V8, he/she just needs enough power to reach his destination in time. A V8 as well as a small vehicle can accomplish this. So the hybrid vehicle was introduced.

How it works?

The hybrid vehicle works by using electric as well as gasoline power. Diesel electric vehicles are also there but there numbers are quite low. The hybrid vehicle works by using electric power when the requirement for engine power is low for example when starting the vehicle and up to the speed of 30-40 mph as the electric source cannot run a vehicle by itself.

What is the basic idea behind Hybrid automotives?

The basic idea is to use a smaller lightweight engine to run a vehicle up to a required speed and when the car has to accelerate then the electric source can add some extra power to gain more speed. As a 1.0 liter engine can also move at 75 mph just like a V8 although the V8 has more acceleration power so why waste fuel on a muscle car when a 1.0-liter vehicle can work for you.

Types of Gasoline Hybrid Vehicles

There are two main types of gasoline hybrid vehicles: parallel hybrid car and series hybrid car. The series hybrid car uses the gasoline engine to turn a generator that can either charge the batteries or run an electric motor whereas the parallel hybrid car can combine the two power sources to give more power or the same amount of power but with a better mileage.

Body Structure of Hybrid Vehicles

Now the question arises how the hybrid vehicle can deliver these types of performances when they have such a small engine. They do so by using lightweight materials like carbon fiber composites, low-rolling resistance tires and advanced aerodynamics to reduce drag. The hybrids can even turn the gasoline engine off when not needed such as when stopping at traffic lights. Some vehicles even use the electric power to gain a speed of 30 to 40 KM/h. Some vehicles also use regenerative braking. By this method when breaks are applied, the car decreases the speed by cutting some amount of power. This power is then used by the generator to generate electric power that can be stored for later use.

The price of these vehicles start from 23000$ and they reach up to 54000$. There are some hybrid SUVs are also available in the market.

Should I Buy New Motorcycle Engines or Used Motorcycle Engines?

June 13th, 2009 by engineering magazines

It depends a lot on what you intend to use your Motorcycle Engines for. If you are going to be using the Motorcycle Engines solely for installation on motorcycles, then used Motorcycle Engines may do already (though if you really want to splurge, new ones are even better.) But what if you were going to place the Motorcycle Engines in cars (rather than car engines)? How would that work out?

Actually, this is already being done by many car assembly hobbyists. Usually, the cars to be powered by Motorcycle Engines are just small cars whose size and weight specifications are proportional to the power output of the Motorcycle Engines. As far back as the 1940s, the Cooper Car Company had been undertaking this practice – to make race cars, at that. Even BMW had tried doing that too in the 1950s. Though the general public may be ignorant of this trend, motorcycle and car assembly hobbyists know this practice works and with relatively good results. Their creations might be known as motorcycle/car hybrids.

The motorcycle/car hybrids are probably still being built today in someone’s backyard with better results than those experienced back in the 1940s and 1950s – all because modern day Motorcycle Engines are stronger, faster, and better engineered than their early ancestors. Thanks to the decades of research done on how to improve Motorcycle Engines, hobbyists are reaping better rewards from their hybrid assembly efforts.

However, just because it looks like a car, runs like a car, and seems to behave like a car doesn’t mean your motorcycle/car hybrid is automatically allowed on public and private roads in your country. The fact that you are using Motorcycle Engines to power the hybrids may be breaking the law for motor vehicles at some point (especially if you are one of the first to make and try to run these types of hybrids in that country.) So, unless you have some kind of special permit to run your hybrid on public and private roads, you may have to confine use of your Motorcycle Engines-powered hybrid vehicle in special areas only (like in a private racetrack or in an enclosed private family compound.)

If you are attracted to the idea of building motorcycle/car hybrid vehicles powered by Motorcycle Engines by yourself, be forewarned that the process actually entails quite an all-encompassing knowledge of how Motorcycle Engines work, how cars work, and how you can bridge any differences in the engineering of both or either with your own creativity and resources. A very smart mechanic/hobbyist can probably learn from manuals and prototypes alone – but for the less experienced and less talented hobbyist, full-time tutelage under someone very experienced in creating motorcycle/car hybrid vehicles might be more appropriate. There’s no shame in asking for experienced guidance (except maybe to your ego) and in the end, you may get better results that way.

Equally surprising is that companies have been established throughout the world which concentrate on creating such motorcycle/car hybrid vehicles, many for racing. It might benefit you if you did research on how these companies do their work before you set about creating your own motorcycle/car hybrid vehicle.
