Hydrogen engine has been towering

But, when I learned that BMW Hydrogen 7 hydrogen engine for many years, instead of Toyota "eyebrows teaser", to tinker with a hydrogen fuel cell-powered 5-series GT, desolate inner monologue is, "the front road narrowing , Please drive carefully. " In essence, the hydrogen engine does not lose the internal combustion engine mode, followed by the principle is still the most common Otto cycle, which is used in the general four-stroke engine cycle, the efficiency of an impulse does not break the threshold. In other words, the idea of ​​the hydrogen engine is "in situ transformation", the original burning gasoline engine "transformation" into burning hydrogen. The benefits of doing so many, without having to do more to change the original car is more obvious a major advantage. No wonder the year of the BMW Hydrogen 7 is equipped with a 6.0-liter V12 "oil hydrogen dual-use" engine, the car has a hydrogen tank, there is a storage tank, full hydrogen life of 200 km, and 74 liters of fuel tank You can also provide 500 km of mileage, the steering wheel has a H2 button, you can switch the "hydrogen drive", or "oil drive."
