Topic: Electric Hybrid Cars vs Gas Powered Cars
Excerpt from Term Paper:
Literature that is associated with actual vehicles is often provided by designers and manufacturers of such vehicles as they attempt to sell their significant economic outlay to consumers. The footage in the film, Who Killed the Electric Car? showing individuals using such technology and even president George W. Bush attempting, though rather stiltedly, to fill the tank of an alternative fuel vehicle are examples of marketing. It is difficult to actually find documented research on alternative fuel cars, that is conducted by non-vested research parties.
Current technology briefs with regard to the most efficient combustion engines stress their new and improving efficiency over previous models. Yet, these are still combustion engines and they still directly burn fuel.
lean-burn engines will undoubtedly allow major improvements in efficiency. Leanburn engines are those that operate at high air-to-fuel ratios. The gasoline direct-injection engine (GDI), is an example. ... With its higher ratio of air to fuel, engine efficiency is higher because more of the heat goes into increased pressure in the cylinder... work output can be varied by changing the fuel input without changing the amount of air admitted to the cylinder. This means much less use of the throttle and, since throttling is a frictional process, enhanced efficiency. ... temperatures are lower, so less heat is lost from the cylinder. (Ross 92)
Additionally, it is clear that the utilization of these more economic engines has resulted in increased size and power of vehicles rather than smaller vehicles that have a potentially lower effect on the environment. Not a win, win situation for anyone but the auto and oil industries. The hybrid engine, which the pure EV enthusiasts laugh at, due to its obvious attempt to go half way when the technology has proven repeatedly that going all the way is certainly possible, is described below.
One promising version would use a small engine - for example, a one-liter two-cylinder direct-injection engine - which would be about 75 percent more efficient in moderate driving than today's typical six- or eight-cylinder engine. The engine would kick in only at moderate to high speeds or…
