What does car ice mean?

This refers to the traditional automobile engine that uses fuel to generate power through combustion.

Automobile ice is a kind of heat engine, which mixes fuel with air, releases energy in the process of combustion and explosion, pushes the piston to move, generates mechanical power and drives the automobile to move forward. Internal combustion engines usually use gasoline or diesel as fuel. They inject fuel into the combustion chamber through the ignition system or fuel injection system, and then ignite or compress the fuel to make it burn.
