Alternatives to Conventional Internal Combustion

For national defense, the Electric Vehicle and Hybrid Electric Vehicle Technology (EHV) program was created in 1992 as an alternative to the conventional internal combustion engine meeting. The specific purpose of this program is to address the issues of performance, stealth, and fuel consumption required by the military. The EHV program was managed by the Department of Defense and Department of Defense Advanced Research Projects Agency (DARPA), but DARPA developed F - 117 stealth fighter aircraft from the mid - 1970 's to the early 1980' s.

A hybrid electric vehicle (HEV) is a hybrid vehicle combining a conventional internal combustion engine (ICE) system and an electric propulsion system (hybrid vehicle transmission system). The presence of the electric power train is aimed at achieving superior fuel economy and superior performance than conventional cars. There are various types of HEVs, and the degree of function as an electric car (EV) varies. Hybrid electric tracks (pickers and tractors) and buses also exist, but the most common form of HEV is a hybrid electric vehicle.

In a parallel hybrid vehicle, the electric motor and the internal combustion engine are combined so that they can power the vehicle individually or together. The most common are internal combustion engines that are connected via a clutch whose electric motor and gearbox are automatically controlled. In the case of an electric drive, the clutch between the internal combustion engines is open and the clutch of the gearbox is engaged. In combustion mode, the engine and the motor operate at the same speed. The power split hybrid electric drive train has two electric motors. It is a traction motor and an internal combustion engine. The motive power from the two motors can be shared by the power split device to drive the wheels, and the power split device is a simple planetary gear device. The ratio can range from 100% of the internal combustion engine to 100% of the traction motor, or any ratio between the two, for example 40% of the electric motor and 60% of the internal combustion engine. The internal combustion engine can serve as a generator for charging the battery

Internal combustion engines are mainly used for transportation. Several other applications are available for every portable opportunity that requires a non-electric motor. The maximum application in this case is an internal combustion engine driven generator. In this way, you can use the standard power tool moved by the internal combustion engine. These advantages are portability. It is more convenient to use this type of engine in a car than to move it. Even in the case of a hybrid car, we will use an internal combustion engine to charge the battery. The downside is that they bring pollution. Not only is it obvious air pollution, it also contaminates damaged or obsolete engines and waste parts, such as oil or rubber products that must be disposed of. Noise pollution is another factor, and many internal combustion engines are very noisy. Because of the loud volume, hearing protector is necessary to prevent damage to the ear. Another drawback is the size
