Injector Guide To Help Identify Your Injectors

Saturated and Peak & Hold are two types of fuel injectors that differ in how they are driven (electrically controlled) by the engine’s electronic control unit (ECU). The main difference between the two lies in how the injector solenoid is energized and controlled to open and close the injector.

Gasoline Direct Injection (GDI) injectors work by delivering fuel directly into the combustion chamber of an internal combustion engine, rather than into the intake manifold as in traditional port fuel injection systems.

Piezoelectric fuel injectors use piezoelectric materials to precisely control the injection of fuel into an engine's combustion chamber. These injectors are commonly used in modern diesel and gasoline direct injection (GDI) engines, where high precision, speed, and efficiency are required.

Piezoelectric injectors and GDI injectors (Gasoline Direct Injection injectors) are both types of fuel injectors used in modern internal combustion engines, but they differ significantly in terms of technology, performance, and functionality.

Yes, ethanol can damage port fuel injectors, but the extent depends largely on the injector’s construction and materials. Older or non-ethanol-compatible injectors often use rubber seals, plastic components, or certain...

The frequency of cleaning your fuel injectors depends on your vehicle, driving conditions, and the type of fuel you use. Proper maintenance ensures optimal engine performance and prevents costly repairs....

Most Port fuel injectors (MPI) operate on 12 volts in standard gasoline engines. However, the voltage required to trigger a fuel injector depends on the injector type and the vehicle’s...

When testing fuel injector coils, there are two primary methods: a resistance check and an insulation check. However, insulation testing applies only to piezoelectric injectors; it cannot be performed on...

Piezoelectric gasoline fuel injectors are high-performance Gasoline Direct Injection (GDI) injectors that use piezoelectric actuators instead of traditional solenoids. These injectors offer ultra-fast response times, finer fuel atomization, and multiple...
