Unlike with carburetors (which use about 7 psi), fuel injection relies on much higher fuel pressure (usually between 38-50 psi). The elevated pressure helps atomize the fuel as it flows through the ...

Long before electronic fuel injection or even performance Holley carburetors, high-end racers operating primarily at wide-open throttle used a purely mechanical, constant-flow fuel-injection system ...

The key ingredient to maximizing the peak performance of a diesel engine is increasing the amount of diesel being burned. On old mechanical-injection engines, the only way to do this was to modify the ...

This is the twin TBI setup attached to the top of the new cross-ram manifold. Note that fuel enters the left TBI unit first and then on to the right unit before being returned to the tank. Although ...

Most new petrol cars you see today are equipped with fuel injection systems or injector motors. These have almost wholly supplanted older carburetor motors. They are more reliable, effective, and ...

SAE Transactions, Vol. 104, Section 3: JOURNAL OF ENGINES (1995), pp. 112-127 (16 pages) A computer model solving the 1-D flow in a typical fuel injection system for direct-injection diesel engines is ...
