Question

Accepted Answer

An engine is a machine that converts fuel into mechanical energy. There are two types of engines: petrol and diesel.

An engine is a device that converts fuel into mechanical energy to power a vehicle or machine.
Petrol engines use a spark plug to ignite the fuel-air mixture, while diesel engines use compression to ignite the fuel.
Petrol engines are generally more powerful and responsive, while diesel engines are more fuel-efficient and have more torque.
Other types of engines include electric engines, hybrid engines, and rotary engines.
The type of engine used in a vehicle or machine depends on factors such as performance, fuel efficiency, and emissions regulations.
