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 ...

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 ...

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 ...

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 that Injector Pulse Width number gets past 100-percent on the data logger, it's time to prepare yourself for a piston or two to spray its glittering guts all over the track photographer. If you ...

This month we will be concentrating on diagnosing a clogged fuel injector using data from a can tool. Diagnosing a clogged injector is not always easy because the symptoms act similar to low ...

This paper describes an evaluation of a series of commercially available natural gas fuel injectors, originally designed for heavy-duty diesel application, for use with hydrogen fuel in an electronic ...

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 ...
