This really depends on your understanding of the word engine.
The Egyptians used various man powered machines (basic cranes etc) but a true engine will run without further human input once started. The main contender is obviously the steam engine which was used as transportation, powered lifting, steam hammers etc.
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.

what is disadvantage of enternal combustion engine
An internal combustion engine is an engine where the fuel combustion happens inside a combustion chamber. There are both Reciprocating and Rotary engines that fall into this category. Most cars on the road today use internal combustion engines. An example would be the V-8 Hemi engines that Dodge puts in their trucks.
Internal engine has its energy ignited in the cylinder. like 99.9% of engines today An external combustion example is a steam engine where the heating prosses is done in an boiler out side the engine.
No the fuel is burnt inside the engine, hence the term "internal combustion"
They were powered by steam engines.
Most vehicles, such as cars, vans, and trucks, use internal combustion engines.
Petrol and diesel engines are internal combustion engines. The internal combustion that turns the engine and powers the wheels is created by the combustion of fuel. No fuel, no combustion, and nothing to drive the wheels.
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.
