Temperature Compensated Accelerator Pump
The temperature compensated accelerator pump will allow delivery of a large pump capacity to facilitate cold engine requirements and a smaller pump capacity during warm engine operation. The amount of fuel delivered during warm engine operation is a function of the rate at which the accelerator pedal is opened. The design incorporates a by-pass bleed controlled by a vacuum operated valve. The input signal controlling the valve position is manifold vacuum switched by a temperature vacuum switch located in the engine coolant system.
