Where does the fuel injector go in a four cylinder engine?
Where does the fuel injector go in a four cylinder engine?
On four-cylinder engines, the No. 2 and No. 3 injectors are in the hottest location and tend to clog up faster than the end injectors on cylinders No. 1 and No. 4. The same applies to the injectors in the middle cylinders in six- and eight-cylinder engines.
What happens when you have a fuel injector leak?
An injector leak will cause the rail to lose pressure while the vehicle is sitting resulting in a longer than normal crank because the rail will need extra time to pressurize. A normal crank time in a diesel common-rail injection system is usually around three to five seconds.
What should the pressure drop be on a fuel injector?
The difference between the maximum and minimum reading is the pressure drop. Ideally, each injector should drop the same amount when opened. A variation of 1.5 to 2 psi or more is cause for concern. No pressure drop, or a very low pressure drop, is a sign the orifice or tip is restricted.
Why are throttle body injectors less susceptible to heat soak?
Throttle body injectors are less vulnerable to heat soak because of their location high above the intake manifold plenum. Heat soak can affect direct-injection injectors due to their placement in the head. Even with the higher pressures, the orifices can become clogged over time. 4. Increase or Decrease in Long- and Short-Term Fuel Trims
What are the problems with the 6.0 injector?
The other injector problem is from what is called stiction. The injectors on the 6.0 have two spool valves on top of the injector. One opens the injector to let high pressure oil in to fire the injector and the other closes it. After time and use, these spool valves will start to weaken.
Why do fuel injectors lean out when under boost?
When the engine is under boost and at a higher rpm, it needs all the fuel the injectors can deliver. If the injectors are dirty and can’t keep up with the engine’s demands, the fuel mixture will lean out, causing detonation to occur. The leaning out may cause higher than normal exhaust temperatures and turbo failure.
What happens if you don’t change the fuel injector?
For port fuel applications, not changing the oil can result in blowby and a compromised PCV system, which builds up contaminates on the tip of the injector. Not changing the oil in an engine with direct fuel injection can result in a worn fuel pump camshaft lobe.
Which is the best brand of 7.3 injectors?
Brand new 7.3 injectors. They are the highest quality, most reliable injectors available for the 7.3. Each Injector is sealed and individually packaged including O-rings and copper crush washers necessary for installation. PER TSB 03-21-39 & TO FIX THE ISSUE KNOWN AS “CACKLE.”
How to make a 7.3 injector a 6.4liter?
Sticking a longer injector in number 8 is a good way to turn that 7.3 into a 6.4liter:jester:. Going with the AE’s might increase the power a little, but the smaller induction on the turbo won’t help them without a chip. AB & AD both flow the same. The timing is slightly different.
Is there a return fee for 7.3L injectors?
We do not send free injectors in advance. Returns- only non-installed 7.3L injectors will be accepted and a 25% restocking fee + shipping will be applied.
