本來是說車子推得推不得(結論是可以),現在被你搞成是否可以推車點火了。好吧,加點細節,應該是基本上現在的車不大可以推車點火

Edit

A vehicle equipped with an automatic transmission (including semi automatic) is difficult to push start since selection of transmission gears is possible only when the internals of such a gearbox are rotating. However, automatics with both front and rear hydraulic pumps can be push-started with no problems. The last American automobile with this type of transmission was the 1969 Chevrolet Corvair with a Powerglide automatic.

Petrol or diesel enginesEdit

A diesel engine uses heat and high compression (compression ratios commonly 22:1 versus 9:1 for gasoline) to ignite the fuel. When normally starting a modern diesel engine, it typically uses glowplugs to preheat the cylinder(s). If a battery is completely discharged then it may not provide the necessary electrical power to 'glow' the glowplugs, making the push starting of a diesel vehicle with a dead battery almost impossible.

Fuel delivery systemsEdit

Fuel injection is most common for modern gasoline and diesel engines. Fuel injection needs electrical power to open and close the fuel injectors. If a battery is of a sufficiently discharged state that it cannot provide the power to turn an automobile self starter then it may also not be possible to activate the injectors. The most common method to start such a vehicle engine is to jump start it.
