Injection engines are more efficient than carburetor engines because they can deliver the fuel more precisely and at a higher pressure. This results in better combustion and fuel economy. Injection engines also emit less pollution than carburetor engines because they can more effectively control the amount of fuel that is burned.
There are two main types of injection engines: port injection and direct injection. Port injection engines inject fuel into the intake ports of the cylinder head. Direct injection engines inject fuel directly into the combustion chamber. Direct injection engines are more efficient than port injection engines, but they are also more expensive to manufacture.
Injection engines are used in a wide variety of vehicles, including cars, trucks, and motorcycles. They are also used in some marine and industrial engines.
