- F02M 69/02 Pumps peculiar thereto
- F02M 69/04 Injectors peculiar thereto
- F02M 69/06 characterised by the pressurisation of the fuel being caused by centrifugal force acting on the fuel
- F02M 69/08 characterised by the fuel being carried by compressed air into main stream of combustion-air
- F02M 69/10 peculiar to scavenged two-stroke engines, e.g. injecting into crankcase-pump chamber
- F02M 69/12 comprising a fuel-displaced free-piston for intermittently metering and supplying fuel to injection nozzles
- F02M 69/14 having cyclically-operated valves connecting injection nozzles to a source of fuel under pressure during the injection period
- F02M 69/16 characterised by means for metering continuous fuel flow to injectors or means for varying fuel pressure upstream of injectors
- F02M 69/28 characterised by means for cutting-out the fuel supply to the engine or to main injectors during certain operating periods, e.g. deceleration
- F02M 69/30 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
- F02M 69/44 characterised by means for supplying extra fuel to the engine on sudden air throttle opening, e.g. at acceleration
- F02M 69/46 Details, component parts or accessories not provided for in, or of interest apart from, the apparatus covered by groups F02M69/02 - F02M69/44
