The engine control computer keep the fuel ratio at 17 to 1. This has been found to give the best performance and fuel mileage. There is not any manual adjustments to be made.
The function of an air flow meter on a fuel injected engine is to check the quality or quantity of air. It sends a signal to the ECM or Electronic Computer Module and in turn, the ECM decides whether to send more fuel to the engine or not.
In a gasoline engine, it is a fuel-air mixture that is drawn in during the intake stroke, unless the engine is fuel injected. In a fuel injected or a diesel engine, it is air, because the fuel (gasoline or diesel) is injected at the "last moment" before ignition.
An air flow meter measures the amount of air entering an engine to help determine the appropriate fuel-to-air ratio for combustion. This helps optimize engine performance and fuel efficiency by ensuring the correct amount of fuel is injected based on the amount of air being drawn into the engine.
If it is a stock engine; or if when you look at the engine, there is a large, round air cleaner on top of it, then it is carbureted, not fuel injected If it is a Wagoneer then it is fuel injected in 87. If it is a Grand Wagoneer then it is carburated.
To supply air to each cylinder on a fuel injected engine and to supply fuel/air on a carbureted engine.
The idle air control (IAC) does this, not the "flapper".
Routes the fuel and air mixture into the engine on an engine with a carburetor or throttle body fuel injection. Routes the air to the engine on a multi-port or direct injection fuel injected car.
it gets hot, and ignites the diesel fuel that is injected by the fuel injectors.
This vehicle is fuel injected and does not have a carburator. The air flow sensor is located atop the air filter housing, the throttle body is on top of the engine with the air supply hose attached and the fuel injectors are located at each cylinder.
A fuel pump sucks it from the tank to the carburetor or injector pump depending on whether it is carbureted of fuel injected. from there it is mixed with air and sucked or injected into the cylinders.
It's flooded. If you have to do it all the time, it most likely means that there is a leaky fuel injector.In a modern fuel injected engine, holding the accelerator pedal - commonly known as the "gas" pedal - down cuts off fuel supply. When you hold the "gas" pedal down, what you're actually doing is allowing more air into the engine which the computer detects and supplies more fuel, unless the engine isn't running in which case it cuts off the fuel supply by disabling the fuel injectors in most cases.This is in contrast to a carburated engine. When you hold down the "gas" pedal you are actually doing the same thing. You are allowing more air into the engine, but with a carburated engine, the air flow controls gas flow which brings more gas into the mix.
The intake manifold routes the fuel/air mixture to the cylinders or just the air on a modern fuel injected engine. The exhaust manifold routes the burnt fuel gases out of the engine into the exhaust system.
