From Drag Times, "Sequential Central Point Injection (SCPI)
GM refined the CPI system into a sequential central port injection (SCPI) system in the mid-1990s. It used valves to meter the fuel to just the cylinders that were in the intake phase. " By all acounts, as much use as a cat-flap in a parachute, apparently .
Vortex engine? Got me. I thought Vortex was just a brand of supercharger. I believe you mean Vortec engine.. GM also called this the L31 (they use 3 letter/number codes for everything) This system used a SCPI (Sequential Central Port Injection) system... and the fuel pressure regulator is on the central unit, which is INSIDE the intake manifold- you have to remove the upper intake manifold to get at it (plastic part), and the Fuel pressure regulator will be on one side of the central unit where all the fuel lines go to, it has a tube on it open to the intake manifold (to read intake vacuum)
cleans the fuel system...
how does fuel system work
fuel di icing system
That's when the fuel system is not operating as designed.
In order to bleed a fuel system on a diesel x-trail you will need to release the fuel in the system. This can be done by removing the fuel system or draining the pump.
The diesel fuel system in a vehicle is similar to the fuel system in a fuel injected gasoline driven car. There is a tank to hold the fuel, fuel lines to deliver it to the fuel pump, and fuel lines from there to the injectors that deliver the fuel into the cylinders at the correct time.
With TBI=165 HP at 4000 rpm. With SCPI=200 HP at 4500 rpm.
A FUEL SYSTEM stores, and supplies fuel to the cylinder chamber where it can be mixed with air (air & fuel ratio) to transmit power
No, the fuel system is computer controlled with relays.No, the fuel system is computer controlled with relays.
No. Normally is is considered part of the fuel system.
Normaly it is called a part of the fuel system.
