How long does a fuel injector cleaning take?
The motor will stop running on its own once the cleaning fluid is all used up. It usually takes 5 to 10 minutes for the cleaner to cycle through the injectors and get used up.
Does the four fuel injector spray at the same time?
All injectors receive the injection signal from the control unit at the same time. Therefore, injection is made independently of the engine stroke cycle (intake, combustion, and exhaust).
What is injector duration?
Injection duration is the period of time during which fuel enters the combustion chamber from the injector. It is the difference between EOI and SOI and is related to injection quantity. Injection pattern. The rate of injection of fuel often varies during the injection duration period.
Do injectors have a firing order?
Firing order does not effect spark at the plugs because that is still determined by what order you put the plug wires on the distributor cap. But if you have a sequential fire fuel injection computer, then the computer program opens the injectors in the same order as the camshaft timing.
Which injection system fires all the injectors at the same time?
A simultaneous system fires all 4 injectors at the same time with each cylinder receiving 2 injection pulses per cycle (720° crankshaft rotation). A sequential system receives just 1 injection pulse per cycle, timed to coincide with the opening of the inlet valve.
Is there a Kill Switch on a Volvo Penta 5.7?
It has 12 v on the pos side of the injectors but the ecm will not fire the injectors. I have pin testes the grounds for the ecm and the ground side for the injectors and are good. I have looked online for an EFI manual for this and cannot find one. Did you check the kill switch?
How to check fuel pressure on Volvo Penta 5.7?
View attachment 490039 Determine whether the ECM is able to switch the ground pin of the injector with a test light, volt meter,,, or with ignition switch on momentarily apply a ground to the ground pin of the injector (s) to hear if they click, with fuel pressure they should spray fuel.
What kind of fuel injector does Bosch use?
The Bosch 0280158117 is a high performance, high volume fuel injector. The fuel delivery is from a 6-hole disc. It incorporates a narrow cone-shape spray pattern for maximum fuel atomization for modern single-valve and multi-valve engines. High resistance, no inline resistors or resistor box requires for use.
How to calculate the injector constant and dead time?
As everybody knows, there are two variables we can use for injector calibration, namely the injector constant, and the dead time.The last is also dependant on voltage, so we use a table for that one. Now during the iterative process we used to find the correct values for both,two things became apparent:
