Unit pumps on Mack's E7 diesel engine

The Unit Pump system [1] is a modular high-pressure diesel injection system, which is closely related to the Unit Injector system UI, and is designed for use in commercial vehicle diesel engines.[2]

The systems use an individual injection pump mounted on the engine block for each cylinder so it is primarily designed for OHV or "cam in the block" engines.[3] The fuel pumps are driven by an extra camshaft lobe where each pump unit is connected to the injector via a short precise length high-pressure fuel line as opposed to Unit Injector systems which combines both a pump and an injector element in a compact unit.

Both systems feature electronically controlled fuel solenoids for precise timing and the injection of fuel quantity is variably adjusted for each cylinder.
