Fuel and air are mixed in the carburettor and the gas is drawn into the cylinder combustion chamber by the valves. The spark ignites the mixture pushing the valves down and turning the cam shaft, hence "internal combustion".
Therefore it is "combustion chamber".

Combustion chamber
The area is called the combustion chamber.

Cars burn gasoline. Gasoline is pumped into the engine's intake, where it is mixed with air, called an air/fuel mixture. After it is mixed, a valve in the engines cylinder head opens and draws the air/fuel mixture into a cylinder. The valve closes and traps the mixture in the cylinder. In the cylinder is piston which moves up and compresses the air/fuel mixture. In the top of the cylinder, in the cylinder head is a spark plug, which ignites the compressed air/fuel mixture. The mixture explodes and forces the piston back down the cylinder. The piston is connected to a shaft, called the crank, which is connected to the car's transmission, which is connected to the car's drive wheels. When the piston is forced down by the exploding air/fuel mixture it forces the crank to turn, which turns the transmission, which turns the wheels. Without the gasoline, there would be nothing make the explosion which drives the car. Look at the linked page for a more in depth explanation of how an engine works.
gasohol
A mixture of ethanol and gasoline is called gasohol or E10. Gasohol typically contains 10% ethanol and 90% gasoline. It is used as a fuel for vehicles that can run on ethanol blends.
Gasoline (also called petrol) is a mixture of many different complex hydrocarbon molecules that have a roughly similar boiling point. Commercial gasoline also has other substances added to it to improve its performance in internal combustion engines, or to reduce the pollution resulting from its use in those engines.,
This reaction is called combustion.
The reaction is called combustion, specifically combustion of the gasoline-air mixture. The spark ignites the mixture, leading to a rapid release of energy that causes an explosion. This is the principle behind how internal combustion engines work in vehicles.
Gasoline is composed of a mixture of hydrocarbons having 6 to 9 carbon atoms, some linear some cyclic. The laboratory standard "gasoline" used for quality comparison is 100% pure linear octane (i.e. 8 carbon atoms). When burned in an engine with a shortage of oxygen, it does produce smaller hydrocarbons called "unburned hydrocarbons" that contribute to smog.
The chemical reaction is called combustion, where the gasoline and air mixture reacts with the spark to release energy in the form of heat and light, producing carbon dioxide and water as byproducts.
