随着天然矿物燃料的日渐匮乏,以及燃油汽车的迅速增多,促使人们不断寻找高效、低耗、对环境无污染或低污染的“绿色”新能源,将其用作汽车的燃料、动力,便产生了“绿色汽车”。天然气汽车即以天然气为能源的汽车。相比汽油汽车而言,它有许多显著的优点:一是把汽车燃油发动机略作调整,便可直接使用天然气。二是天然气能量转换效率提高,排泄的废气几乎不含对环境有害的成分。三是天然气的价格约比汽油便宜一半。四是使用天然气,发动机的零件磨损轻,可以延长发动机的寿命。总之,经济效益、社会效益极为显著。燃料电池汽车燃料电池汽车,是以燃料电池作为动力的新型汽车。它以燃料电池产生的电能驱动,因此,实质上也属于电动汽车。燃料电池作为一种高效、低
With the growing shortage of natural fossil fuels and the rapid growth of fuel-powered vehicles, people are constantly looking for “green” new energy sources that are efficient, low-cost, environmentally-friendly or low-pollution, and are being used as fuel, power and energy for automobiles Produced a “green car.” Natural gas vehicles that use natural gas for energy vehicles. Compared to gasoline vehicles, it has many significant advantages: First, the car fuel engine slightly adjusted, you can directly use natural gas. The second is that the energy conversion efficiency of natural gas is increased, and the excreted exhaust gas contains almost no harmful ingredients to the environment. Third, the price of natural gas is about half cheaper than gasoline. Fourth, the use of natural gas, engine parts wear light, you can extend the life of the engine. In short, economic benefits and social benefits are extremely significant. Fuel cell vehicles Fuel cell vehicles, fuel cell powered as a new type of car. It is driven by the electricity generated by the fuel cell and, therefore, essentially belongs to the electric car. Fuel cells as an efficient, low
