Continuously operating fuel injection system

摘要

A continuously operating fuel injection installation which includes an air-quantity measuring device in the suction pipe and a fuel-quantity distributor controlled thereby, is equipped for use with a multi-cylinder aircraft engine, with an auxiliary device that serves to achieve the best possible power output, fuel economy and flight safety; for that purpose, a height control pressure regulator is connected to the control pressure line leading to the fuel-quantity distributor in parallel to a warm-up regulator, which meters the control pressure and therewith the fuel admixture corresponding to the air density changing with temperature and pressure; by interconnecting a fixed throttle between the control pressure line and the fuel return line to the fuel tank, an emergency operation of the engine is assured in case of failure of both regulators.
