Best Answer

Direct injection works somewhat similar to regular fuel injection, but at a MUCH higher PSI. say a non-direct injection car's fuel pressure is anywhere from 40-60SPI, a direct injection fuel pressure runs in the couple of thousands of PSI for gasoline and up to and more than 20,000 PSI for diesel direct injection.

the other difference is instead of the injector spraying the fuel into the intake manifold runner (where it has to travel a short distance to the combustion chamber, some fuel doesn't stay as a fine mist, it will stick to the wall of the runner and bead up, like rain on a window) direct injection sprays, you guessed it, DIRECTLY into the combustion chamber. it gives a good boost to compression, which gives you more power and better efficiency

How does ceramic injection molding work?

Ceramic injection molding is similar to plastic molding. It uses a machine that heats ceramic at a very high temperature. It will melt it than it will heat it to make it stay.


What is vehicle injection computer?

Normally this unit is called an ECM (Electronic Control Module), injection computers are normally used in the aftermarket fuel injection systems.Basically the system works by controlling the pulse width (injector timing) of the injectors compaired to several factors:Fuel line pressureRPM's (engine speed, not vehicle speed)Air flowAmbient air temperatureOxygen (in exhaust)Engine temperatureBarometric pressure (only on some systems, other systems 'guess' the pressure based on output readings)Manifold VacuumThrottle position (user demand)


Will a 1984 Chevy pick-up motor go into a 1989 Chevy pick-up?

Yes. Both should have throttle body fuel injection. It should be a direct bolt in.


What is the normal working pressure of fuel pump?

Depending on the engine and fuel type...Diesel - direct injection fuel pumps generate approx 1600 bar (23 200 psi) for common rail systems, as for the pump-nozzle injector diesel systems (pumpe - duse German translation), the pump can generate over 2000 bar (29 000 psi)Gasoline engines have electric fuel pump located inside a fuel tank, and produces approx 3 bar of pressure (43 psi).

How can you wire a fuel injection engine up in a vechicle which did not have injection before?

There is not an easy way to do this. An injection system has to have a computer to work and a computer for a carburetor system will not work. There are some after market systems that include all the parts, but are usually expensive.
