electronic sequential port fuel injection

When the intake valve opens, only a portion of the fuel injected will be in suspension when the air enters the cylinder, the remainder may be running down the port wall as liquid. If an injector is triggered at the wrong crank angle, fuel may collect in areas of the intake port or cling to the runner walls. The problem is that while some injectors will be close to properly timed, others will not. The good thing about the group fired system is it’s low cost. The ignition system or crank trigger provides the signal to the electronic control unit (ECU) for speed input and thus This injection system generally triggers a group of the injectors simultaneously. Below is some of the basic information on the two types of systems so you will have a better understanding of their operation. There are two basic types of multi-port EFI : Group and Sequential. The first decision on EFI is which type of electronic control unit is the best suited for the application and budget. Our staff is here to help you sort through the ‘mysteries’ and give you the “real” information so that you can make an informed and educated decision.

Kinsler offers six manufacturers electronics, each manufacturer has several models. When choosing an electronic fuel injection system there are many features and options, it can be confusing. The most commonly sensed inputs are:ģ) Barometric pressure or manifold absolute pressure (M.A.P.)ĥ) Water and/or oil temperature, and sometimes fuel temperature With it’s many sensors and input signals it can be tuned to meet the demands of an engine operating over an extremely broad range of conditions. Electronic fuel injection metering, when properly designed and programmed, is today’s accurate way to introduce fuel to an internal combustion engine.
