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 ...

Just about every new vehicle is fuel-injected. (The last carbureted vehicles came off the assembly line in 1990.) Although they’re more expensive to service than carburetors were, fuel injection ...

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 ...

We're always looking for ways to improve fuel economy and performance in classic Mustangs. As time goes on, the time-proven carburetor is showing us how antiquated it can be at times with rough idle, ...

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 ...

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 ...

When you think of hot rodding, old carburetors, and high horsepower you don't necessarily think of great gas mileage or, for that matter, easy starting on those cold mornings. Now, when you think of ...

The mixture preparation and hydrocarbon (HC) emissions behaviors for a single-cylinder port-fuel-injection SI engine were examined in an engine/dynamometer set up that simulated the first cycle of ...
