An internal combustion engine (ICE) is a heat engine that converts the chemical energy of fuel into shaft work. In an ICE, fuel and an oxidizer are combusted in a combustion chamber, which is part of the engine's working fluid flow circuit. The engine then partially converts the energy from the combustion to work. 

An internal combustion engine (ICE) converts chemical energy in fuel into mechanical energy. The process of combustion, or burning, is the basic chemical process of releasing energy from a fuel and air mixture. In an ICE, the ignition and combustion of the fuel occurs within the engine itself. 

Here are some basics of an ICE:
Fuel: The ICE uses fuel to create an explosion (power) to move a piston down.
Oxygen: Oxygen supports combustion.
Ignition source: An ignition source starts combustion.
Combustion: The chemical energy of the fuel is first converted to thermal energy by means of combustion or oxidation with air inside the engine.
Thermal energy: The thermal energy is converted to mechanical work through the expansion of the working fluid.
Working fluids: The reactants of combustion (oxidizer and fuel) and the products of combustion serve as the working fluids of the engine.
Geometry: The geometry of reciprocating internal combustion engines is commonly characterized by several parameters including: swept volume, clearance volume and compression ratio.
Cylinder pressure: The pressure exerted by the combustion process within the cylinders of an ICE. 

Note: The main difference between a 2-stroke and 4-stroke engine is the number of stages it goes through to complete a power stroke. A 2-stroke engine completes a power cycle with two strokes of the piston during one crankshaft revolution. A 4-stroke engine goes through four stages, or two complete revolutions, to complete one power stroke. 
 

IC engines have several advantages over external combustion engines:
Smaller heat loss: The fuel burns directly in the cylinder of an ICE, so heat loss is smaller.
Higher thermal efficiency: IC engines have a higher thermal efficiency.
Lower fuel consumption: IC engines consume less fuel. 

However, IC engines also have some disadvantages:
Expensive fuel options
IC engines commonly use expensive fuel options, such as gasoline or diesel.
Higher emissions
IC engines tend to have higher emissions compared to external combustion engines.
Not suitable for large-scale power generation
IC engines are not suitable for large-scale power generation.
Reciprocating internal combustion engines produce noise
Reciprocating internal combustion engines produce noise due to fuel detonation.
