When the auto manufacturers first introduced their newfangled multiport fuel-injection systems, many hot rodders feared that the days of performance tuning and tweaking were gone. However, nothing was ...

Most modern vehicles have multi-port fuel injection (MFI) with a separate fuel injector for each cylinder. This system mixes the fuel and air together right in the intake port for eachengine cylinder ...

Many car crafters roll their eyes and tune out when bench racing turns to electronic fuel injection (EFI). We're not here to hijack you into believing that EFI is cheap or even simple. Carburetors ...

The fuel injector is the least understood component of the EFI system, but it is a critical part for a successful calibration. The job of fueling the cylinders comes with many design and engineering ...

Fuel injection systems inject fuel at just the right time and place to mix with air and form the mixture that drives the engine. Just about every new vehicle is fuel-injected. (The last carbureted ...

The droplet size of the fuel droplets produced by injector systems plays a central role in the control of the efficiency of the combustion process and the production of harmful emissions. As the ...
