Hitachi® FIJ0059 - Fuel Injector

A fuel injector sprays pressurized fuel supplied by the fuel pump. On Direct Injection engines, the fuel is sprayed directly into the combustion chamber. On Port Injection engines, the fuel is sprayed into the intake port towards the intake valve. When the engine control computer commands the injector, a solenoid in the injector lifts a valve off its seat and fuel flows. The injector on-time, also called pulse width, determines the richness of the air/fuel mixture. This part is critical for dependable engine operation, fuel economy, and reduced emissions. Although usually very reliable, fuel injectors can leak, short out, become clogged or otherwise malfunction, causing a variety of troubles from bad fuel mileage to increased emissions. If you need a quality fuel injector to replace a faulty component, get a premium part from Hitachi, an internationally renowned original equipment manufacturer and a world class quality leader. Designed to meet or surpass OE performance specifications, Hitachi fuel injectors are tried and tested to ensure the proper fuel supply required by your vehicle to maintain optimal engine power.

Each injector is carefully constructed by the engineers at Hitachi to keep the fuel delivery system operating at peak performance throughout the life of your vehicle. Hitachi Quality system and ISO/TS 16949-2009 guidelines allow it to be the leading manufacturer of gasoline injectors. Plus, to meet the requirements of environmental regulations and reduce harmful emissions, Hitachi develops various kinds of technology for injection spray shaping and components based on consumption analysis technology and utilizes them in the manufacturing process.
