Abstract
A fuel injection pumping apparatus includes an injection pump having a piston which can be subjected to a varying fluid pressure to determine the timing of injection of fuel. Resilient means is provided to bias the piston and a member is provided to act as a stop for the piston. The member is coupled to a temperature responsive device whereby when the engine is cold, the stop determines the position of the piston so that a predetermined timing is obtained for starting the engine. The stop moves when the engine is warm to permit the piston to vary the timing of the apparatus over the full range.
