injection pump is a device used in fuel injection systems to pump fuel into the engine cylinders at a high pressure. It is typically driven by the engine's camshaft or a separate drive shaft. The pump draws fuel from the fuel tank and pressurizes it to a level that allows it to be injected into the combustion chamber.

Injection pumps are commonly used in diesel engines, where the fuel needs to be injected at a high pressure to ensure proper atomization and combustion. They are also used in some gasoline direct injection systems.

There are different types of injection pumps, including rotary pumps, distributor pumps, and common rail pumps. Each type operates in a slightly different way but all serve the purpose of delivering fuel to the engine at the required pressure.
