What does ice model mean

ICE models are automobiles that use an internal combustion engine as their power source, where "ICE" stands for "Internal Combustion Engine". The heat generated by the combustion of fuel inside an ICE vehicle drives the engine, which in turn drives the vehicle. Internal combustion engine automobile working principle is fuel mixed with air, combustion inside the engine to produce high temperature and high pressure gas, piston movement thermal energy into mechanical energy to drive the vehicle. The power source is mature in terms of fuel refueling and refueling station infrastructure, and there are challenges in terms of emissions pollution and energy efficiency.
