Hydrogen-powered
Vehicle
Hydrogen-powered vehicle is a truly zeroemission vehicle, emissions of pure water, which has a non-polluting, zero emission, is the best alternative to conventional car. Advantage: rich source of hydrogen; the emission is water, no pollution. Disadvantage: The high manufacturing cost of hydrogen fuel cells, and hydrogen fuel storage and transport in accordance with the technical conditions is very difficult.

Pure Electric Vehicle
As the name implies the pure electric vehicles are the cars use electric power. Most of them use electric directly, also have some others use four wheels as the four motors’ rotors. Advantage: no exhaust, no pollution, technology is relatively simple and mature. Disadvantage: the energy stored in the battery unit weight too little, and the battery’ manufacturing cost is too high, some even more expensive than the car.

Natural gas and liquefied
petroleum gas vehicle
Most of this kind of vehicle use double fuel system, namely a compressed natural gas or liquefied petroleum gas systems, and a gasoline or diesel combustion systems, can easily transition from one system to another system, this car is mainly used for urban public transport vehicles. Advantage: Gas single component, high purity, uniform mixing with air and burned completely, CO and particulate emissions are low, the engine starting at low temperature and better running performance. Disadvantage: Its transport performance is poor than the liquid fuel, low volumetric efficiency of the engine, the ignition delay is longer and dynamic decreased.

Fuel-cell Vehicle
Fuel-cell vehicle is that car use hydrogen or others as fuel, through the chemical reaction create electric current to drive the car. Advantage: Fuel-cell’s energy conversion rate is twice the internal combustion energy, or even higher; the chemical reaction progress of fuelcell does not produce harmful exhaust; running smoothly, no noise, so the fuel-cell vehicle is a kind of ideal vehicle . Disadvantage: manufacturing cost is too high, current technology is difficult to achieve the industrialized.
