A car's energy source is the chemical energy of it's fuel. This energy is liberated as
thermal energy in the pressurized heated gas products. The expansion of the gases
in the engine's cylinders, now mechanical energy, is directed toward the mechanical
devices that will direct this energy to the rotation of the wheels.
A car's engine is a heat engine. It transforms thermal energy in the form of heat to mechanical energy. But according to thermodynamics 2nd law, it cannot transform all of the heat to mechanical energy, just some amount. The rest of the heat has to be
dissipated to a low temperature heat deposit (or heat sink). That's why a car needs
a heat dissipating system (the radiator).

A heat engine
The generic term is "heat engine".
The internal combustion engine converts chemical energy into mechanical energy to make a car move. The chemical energy in gasoline and water are converted into thermal energy. This energy causes the pressure that forces the pistons to move. The pistons transform the thermal energy into mechanical energy.
The thermal energy output of the new engine was inefficient, as the thermometer quickly demonstrated.

heat engine
An internal combustion engine converts chemical energy into Thermal Energy, and converts thermal energy into mechanical energy via the pistons, connecting rods, and crankshaft .
A heat engine
An engine is a motor that converts thermal energy to mechanical work.
