They are both internal combustion engines
Reciprocating engines (piston engines) are internal combustion engines. Rotary engines ( Wankel engine) is also an internal combustion engine. In general, all types of engines in which the combustion chamber is an integrating part of the engine is considered a internal combustion engine.
The most popular combustion engine is the internal combustion engine. It is used most often in spark ignition engines such as cars or lawn mowers. Diesel combustion engines are generally large trucks and construction vehicles.

No, they are both internal combustion engines.
Gasoline and Diesel engines are internal combustion engines. The fuel explodes (combusts) internally (in the cylinder) and releases energy that is used to move the vehicle. Electric engines and steam engines are not internal combustion engines by definition. Steam engines combust their fuel externally to the "engine". The vast majority of passenger vehicles produced throughout history are driven by internal combustion engines.
Important products of this industry include armatures, starting motors, alternators, and generators for automobiles and aircraft, and ignition apparatus for internal combustion engines, including spark plugs, magnetos, coils, and distributors.
