The Peak current is the amount required to quickly jolt the injector open, and then the lower Hold current rating is used to keep it open for as long as the ECU commands. When the solenoid is energized, the core and needle is pulled back, allowing the fuel to discharge. This is the most common type and still the best. This type of driver works by supplying 12 volts to the injectors and the ECU turns it on and off to establish a fuel injector pulse. This injector family portrait includes four of the five popular GM fuel injectors. JavaScript is disabled. We are in the process of building our Fuel Injector Development online market. Fuel injectors should be tested cold unless otherwise specified, temperature variances will change the readings. Unfortunately, several Japanese manufactuers, notably Subaru and Toyota decided to make their own style connectors in the late '80s. The fuel injector resistance will be about 11-18 Ohms. The Bosch disc type uses the same type of actuation mechanism as the pintle type but replaces the pintle with a flat disc and a plate with tiny holes. For this test the injector must be removed. The Lucas type buries the disc up inside the body to reduce the mass of the assembly for quicker response. A fuel injector can cause a miss almost identical to an ignition miss in an engine. These fuel injectors can be cleaned by pulsing them thousands of times while they are in an ultrasonic cleaner. The trend lately is to use high impedance types in most production cars. Low impedance injectors are found on high performance and larger injectors. Specifically, that none are shorted or open internally. Most high flow injectors are low resistance (2-5 ohms) and use a peak and hold driver to activate them. So, how much power is this injector good for? 1.800.381.2065 . Newer injectors use a 14mm round section O-ring sitting in an isolated groove. Performance Injector Solutions Specifications: Suitable for Fuels: All Gasoline & Oxygenated Fuels Resistance: 12 OHMS Operating Voltage: 13.8v.
