Abstract
Adjustments are preset to factory specifications, during assembly of a vehicle engine, which limit the maximum amount of fuel, per stroke, being injected by each injection pump. Because of these preset adjustments, an increase in fuel temperature above a critical point can cause a power loss. A compensator (30) is provided to vary the preset adjustments. The compensator includes a member (70) which responds to fuel temperature increase and permits more volume of fuel per stroke to be injected by each injection pump.
