Are there 2 injectors in a Honda Civic?
BRZ, FR-S, Toyota’s newest DI V6, and the new NSX are a few to use 2 injectors per cylinder. Gonna be interesting to see how this plays out for the Civic. Click to expand… Maybe Honda managed to program the ECU to reduce carbon deposits. Theoretically it can be done by adjusting spark and valve timing.
How is fuel injected in a Honda Accord?
Fuel is only injected when it is needed – during each cylinder’s intake stroke. This is referred to as sequential fuel injection. Inside the injector there’s a spring-loaded plunger that closes against a valve seat. Once seated, the flow of fuel is blocked.
When did Honda start using Programmed Fuel injection?
Fuel Injectors (cont.) In 2001 a new type of injector was introduced on some models. This is a multi-outlet design with a ball shaped plunger in place of the tapered needle plunger. Both four and twelve outlet injectors are used in the new Programmed Fuel Injection (PGM-FI) models. These provide a finer spray of fuel for better atomization.
How can I tell if my car injector is working?
Any major difference and that injector should be inspected to make sure that it is firing correctly. Tip: You can find the correct resistance for your injectors by searching online or in your vehicle’s repair guide. Step 1: Turn the car on. Turn the key to the second (ON) position for this test.
Which is the hot side of the fuel injector?
One side is hot/12v the other side is ground to fire the injector. The ground side is controled by the ecu. The best thing to do is get a manual/wire diagram at hondatech.info: Honda service manuals and stat unplugging stuff till you find out what happens.
Why does my fuel injector keep coming back ol?
One side should come back OL (ground side) and the other should come back .0001 Ohm (hot side) Then grab a noid light and check for injector pulse during priming. If the noid stay on then your injector ARE staying on. After check fuel pressure at the rail, this can cause rich issues.
How to check fuel injector pulse during priming?
What you need to do is check ground on one side and hot on the other with an ohm setting on your meter. One side should come back OL (ground side) and the other should come back .0001 Ohm (hot side) Then grab a noid light and check for injector pulse during priming.
How big is the Honda D15B fuel injector?
Electronic injection system was mainly used in these engines, but the first versions used carburetors. Honda D15 firing order was 1-3-4-2. The size of D15B throttle body was 56 mm. The size of D15B fuel injectors was 240 cc. Along with D15, D-series also included D12, D13, D14, D16, D17, and ZC.
