What kind of fuel injector does a marine engine use?
What kind of fuel injector does a marine engine use?
We have previously examined marine diesel engine fuel injection systems where we looked at the Common Rail Diesel Injection System (CRDI). When burning heavy fuel oil, the injector will require cooling for efficient operation.
How does a cooled fuel injector keep the engine cool?
The valves are also cooled by recirculating the fuel oil around the fuel valve when not under pressure or when the engine is stopped. This also keeps the fuel oil hot and viscous, ready for the next injection.
Where are the fuel injectors located in the engine?
In large engines with a centrally placed exhaust valve, the fuel injectors are placed symmetrically around the cover and charged from the common distribution connection to inject equal quantity of fuel oil simultaneously. Engine fuel systems are designed for the normal working conditions.
What happens when fuel injector is overheated?
Overheating of the fuel injector nozzle will lead to the nozzle injector holes becoming clogged with carbon and operating inefficiently. 2. The helical spring can become worn and loose part of its tension, this will lead to late cut-off of fuel, the delivery being extended. This is one cause of scavenge fires. 3.
When did Chevy start using Tuned Port Injection?
Chevrolet brought us Cross-Fire injection in 1982, which didn’t impress anyone. In the mid-1980s, GM brought us Tuned Port Injection (TPI), which was tunable and certainly a smashing success. TPI endured and remained an industry standard for years.
What kind of central port injection does a Vortec engine use?
The L35 and LF6 Vortec engines from the mid-90’s to early 2000’s had a “central port injection” setup which is known as the “spider”. The spider system uses a central pump with 6 tubes connected to it that lead to each of the 4.3L vortec cylinders.
