Abstract
An advance arrangement comprises an advance piston slidable within a bore, the advance piston cooperating, in use, with a cam arrangement of a fuel pump to adjust the timing of fuel delivery by the pump, a servo-piston slidable in a bore provided in the advance piston, a light load piston moveable relative to the advance piston against the action of a light load control spring, a servo control spring engaged between the light load piston and the servo-piston, a light load control valve operable to control the application of fuel to the light load piston to adjust timing under light load conditions, and an independent temperature control valve operable to control the application of fuel to the light load piston depending upon the engine temperature to permit adjustment of the timing of fuel delivery to compensate for cold conditions.
