F02M69/30 - CPC Classification

Classification description:

Low-pressure fuel-injection apparatus ; Apparatus with both continuous and intermittent injection; Apparatus injecting different types of fuel characterised by means for facilitating the starting-up or idling of engines or by means for enriching fuel charge, e.g. below operational temperatures or upon high power demand of engines

Sub-classes:

F02M69/32 » with an air by-pass around the air throttle valve or with an auxiliary air passage, e.g. with a variably controlled valve therein 16
F02M69/34 » with an auxiliary fuel circuit supplying fuel to the engine, e.g. with the fuel pump outlet being directly connected to injection nozzles 7
F02M69/36 » having an enrichment mechanism modifying fuel flow to injectors, e.g. by acting on the fuel metering device or on the valves throttling fuel passages to injection nozzles or overflow passages 2
