Title: Fuel system for spark ignited compression engines - has atmospheric pressure compensating unit with threshold pressure actuated diaphragm
Inventor: KNAPP HEINRICH DIPL PHYS DR
IPC: F02M69/22
Filed: 1974-03-19
Abstract: The inlet channel of the fuel supply system for a fuel mixture compressing, spark ignited engine has a pressure sensitive element and a throttle valve. This pressure sensitive actuating element corrects fuel and air mixture at high altitudes where the air density is lower. The correction is carried out only from an altitude of five hundred metres above sea level. The air flows through a filter and past a flow adjusting plate which directly actuates a fuel metering vale. The pressure sensitive cell actuates a diaphragm of the pressure regulator via the stem at higher altitudes while at lower altitudes it is decoupled. The regulator adjusts the setting of the throttle valve and the air flow adjusting valve. This valve system is readily calibrated and compensates for changes in air densities.
