What should common rail fuel pressure be?
What should common rail fuel pressure be?
Common rail direct fuel injection is a direct fuel injection system for petrol and diesel engines. On diesel engines, it features a high-pressure (2,000 BAR – 29,000 PSI) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors or pump nozzles.
What is the pressure of fuel injector?
Injection pressures during the whole process should be above 1000–1200 bar for a good spray formation and air–fuel mixture; a tendency in practice to 1600–1800 bar and higher is noted. The total nozzle area should be as small as possible in relation to cylinder diameter for good combustion, particularly at part load.
What is Hpcr fuel pressure?
Current HPCR systems are capable of pressurizing fuel up to 29,000 psi (2000 bar). Each HPCR injector is attached to the common rail by a high-pressure line and is electronically controlled by the engine control module (ECM).
How much pressure is in a diesel fuel system?
In many cases, the injector is mounted just like a spark plug would be in a gas engine. But unlike fuel-injected gas engines that inject fuel at 10-60 psi, diesel fuel-injection systems run in the 10,000-30,000-psi range.
What do you need to know about Lycoming fuel injection?
Jacqueline Shipe (A&P/IA) walks you through a typical Lycoming fuel injection system and the most common trouble spots to check if your engine starts running rough. Fuel-injected engines have been common in automobiles for years, and are gaining popularity in General Aviation aircraft.
What causes fuel pressure to increase in a Piper Flyer?
Clogged fuel nozzles When a problem occurs in a fuel injection system, it usually is caused by small pieces of dirt or debris that partially clog a line or injector. If one or more of the nozzles becomes restricted, fuel pressure will increase because the servo keeps sending out the same amount of fuel.
What kind of fuel injection does a Cessna Flyer use?
Direct injection of fuel into cylinders offers better fuel distribution and easy cold starting, without the threat of carburetor icing. Jacqueline Shipe (A&P/IA) walks you through a typical Lycoming fuel injection system and the most common trouble spots to check if your engine starts running rough.
What should I use to clean my Lycoming fuel injection nozzle?
Lycoming Service Instruction 1275C gives instructions on nozzle cleaning. The nozzle should be cleaned with acetone or MEK and blown out with compressed air. No picks or sharp tools can be used in the discharge hole or it will be deformed.
