Four stroke and two stroke are types of internal combustion engines with different cycles of operation.

• Four stroke engines have four stages: intake, compression, power, and exhaust.

• Two stroke engines have only two stages: compression and power/exhaust.

• Four stroke engines are more fuel efficient and produce less pollution compared to two stroke engines.

• Examples: Four stroke - car engines, motorcycle engines. Two stroke - chainsaws, lawnmowers.

A petrol engine is an internal combustion engine that uses petrol as fuel to power a vehicle or machinery.

• Petrol engines ignite fuel using spark plugs

• They have higher power output compared to diesel engines

• Commonly used in cars, motorcycles, and small aircraft

• Examples include inline-four, V6, and V8 petrol engines

An IC engine, or internal combustion engine, is a type of engine that generates power by burning fuel inside the engine itself.

• IC engines are commonly used in vehicles such as cars, motorcycles, and trucks.

• They work by igniting fuel-air mixture inside a combustion chamber to produce mechanical energy.

• There are two main types of IC engines: gasoline engines and diesel engines.

• IC engines require regular maintenance and care to ensure optimal performance.

A carburettor is a device in an internal combustion engine that mixes air with a fine spray of liquid fuel.

• Carburettors are used in older vehicles to control the air-fuel mixture for combustion.

• They work by using the vacuum created by the engine to draw in air and fuel through different circuits.

• Common types include downdraft, sidedraft, and updraft carburettors.

• Carburettors have been largely replaced by fuel injection systems in modern vehicles.

A diesel engine is an internal combustion engine that uses diesel fuel to power the vehicle.

• Diesel engines ignite fuel using compression instead of spark plugs

• They are more fuel efficient than gasoline engines

• Commonly used in trucks, buses, and heavy machinery
