Fuel injector

This article focuses on fuel injection in reciprocating piston and rotary piston engines. All Diesel engines use fuel injection, and many Otto engines use fuel injection of one kind or another. In the former case, replacing the o-rings will fix the problem, while the latter typically calls for the replacement of the entire spider assembly.

All Bosch fuel injectors released to the aftermarket are OE fit, form and function, and are produced to OE specifications. The Bosch fuel injector has a return rate of part per million (PPM), making Bosch the industry benchmark.

Our line of universal and vehicle-specific fuel injectors includes flow rates from lbs. The fuel rail is a cylindrical rail that will run along the top of the intake manifol and each fuel injector will be between the fuel rail and the intake manifold. V style engines (V V V10) will have two fuel rails with half of the injectors on each side of the motor.

The amount of fuel sprayed is increased or decreased by a mechanical or electrical control unit - in other words, it is just like turning a tap on and off. Once the injectors itself or the filter basket becomes clogge no amount of intake or fuel rail induced injector cleaner will resolve the problem. The main causes of fuel injector wear or failure is contamination of the fuel system. Corrosion due to moisture in the fuel also contributes.

Picking the proper fuel injector size is critical for performance and tuning control.

We start with the best base injectors available, and then optimize them for all performance applications, bringing great reliability and performance to all of our products. Use this calculator to determine the best size injector for your setup. Fuel Injector Calculator.

The fuel injector is installed at the intake manifold injection before the inlet valve. It injects the fuel such that it builds a homogenous mixture with the added air. This air- fuel mixture is created by opening the inlet valve of the intake manifold into the combustion chamber where it is ignited by means of an ignition spark and burnt. Fortunately, most fuel injector issues can be fixed with a professional cleaning or replacement of the O-rings if a leak exists there.

But when a fuel injector cracks or breaks, replacement is necessary and it can be expensive. Although fuel injectors are individual, they are designed to work as part of a team with the other injectors. Goes into how to test the fuel injector, theory of operation and other aspects.

This happens when the air to fuel ratio is tilted to one side making it too rich that it could burn the catalytic converter. The unit injector (UI) architecture incorporates the high pressure pumping element, fuel metering and the injector in one device. With the engine off, unplug the electrical connector of the injector you need to test. Checking the Injector Coil.

Download extreme injector v3. It is supplied with ­pressurized fuel by the fuel pump in your car, and it is capable of opening and closing many times per second.

A fuel injector is nothing but an electronically controlled valve.

If fuel is not squirted into the inlet port, the valve inside the fuel injector remains closed by virtue of the tension on its spring mechanism. When fuel is sent to mix with air at the air inlet, the pressure of the fuel opens this valve to allow fuel to be squirted. To diagnose a fuel injector problem you need a keen sense of your vehicle, a little time and some basic fuel injector knowledge.

Buy and wholesale fuel injector parts, fuel injection kit,with competitive price from ruixiao - one of leading fuel pump parts, fuel injection kit suppliers in China. This injector family portrait includes four of the five popular GM fuel injectors. From left to right: original Bosch Jetronic EV the tall LSstyle followed by the early LS truck injector, and on the far right the late LSEVstyle.

Testing of fuel injector is carried out as follows. Mount the fuel injector in its test rig and connect up the oil supply. Under no circumstances should hands be placed under the injector spray. The high velocity oil jet can penetrate the skin and cause blood poisoning.

With the injector priming valve open, operate the hand pump to prime the. Maximum Injector Duty Cycle should be around 80% max for safe operation. This allows for some future horsepower increases.

By changing your fuel pressure, you can change the flow rates of your injectors. No one knows more and no one does it better!

In addition, we provide our customers with the right equipment and a complete line of supplies. If the injector cannot initially overcome boiler pressure, the overflow allows the injector to continue to draw water and steam.
