OEM Quality G3s33 Common Rail Nozzle for Toyota Vigo 2.5 Vnt

Injector nozzle for automotive is actually a simple solenoid valve, when the solenoid coil is energized, suction, the needle valve is sucked, open the nozzle hole, the needle through the needle valve needle and the annular gap between the nozzle hole High-speed spray, forming a mist, which will help fully burn. In the past, diesel injectors were mechanically controlled, and mechanical diesel injectors were used to control precision couplings(needle valves and needle valves). Nozzle nozzle is one of the three traditional precision diesel engine parts, the three precision couplings: plunger, plunger sleeve, needle valve, needle valve body, the valve out of the oil valve seat. Gasoline engine nozzle is part of the gasoline engine control system to replace the carburetor gasoline engine carburetor.

The common rail system now has a big difference from the diesel injection system because the common rail diesel injection system completely separates the injection pressure from the injection process. This also requires a higher common rail nozzle. Now the minimum injection pressure of the common rail nozzle depends on the flow rate of the oil return hole and the oil inlet hole and the end surface area of the control piston. After confirming the structure size of the oil inlet hole, the oil return hole and the control room, the stable and shortest injection process of the injector needle valve is completely confirmed, and at the same time, the stable and minimum injection nozzle Oil volume. Reducing the volume of the control chamber will make the needle valve respond faster and make the fuel temperature less impact on nozzle fuel injection.
