Fuel Injectors – Dynamic Description

Product Overview

This manual provides comprehensive details on throttle-type fuel injectors used in various engine applications. These injectors are specifically designed to deliver fuel into pressurized cylinders, optimizing combustion efficiency and minimizing smoke production.

Key Features

• Orifice Size: Each injector features a 1.0 mm (0.04 in) single orifice.
• Pressure Setting: Injectors are set at a pressure of 14824 kPa (2150 psi) and pressure adjustments are facilitated through shim modifications.
• Injection Angle: Engineered with a precise injection angle of 4u00b0.
• Uniform Injector Pipes: All injectors use pipes of equal length to ensure consistent fuel injection intervals across cylinders.

Benefits

• Efficient Combustion: Maximizes fuel atomization for improved combustion and reduced smoke.
• Durable Design: The injector assembly comprises a robust nozzle and needle valve setup to ensure longevity and reliability.
• Consistent Performance: Engineered for optimal performance with a uniform distribution of fuel to all cylinders.
• Fuel Economy: Enhances engine performance while conserving fuel through advanced injection technology.

Usage Recommendations

• Adjustment and Maintenance: Modify pressure using shims to maintain optimal injector performance based on specific engine requirements.
• Ensure Proper Lubrication: Allow for a small fuel leakage to lubricate the injector components, preventing wear and tear.
• Check Injector Pipes: Regularly inspect for uniformity in length to support precise fuel injection timing.

Fuel from the injection pump enters through the injector inlet, passing through a precise drilling in the nozzle holder to reach the needle valve seat. Pressurized fuel lifts the needle valve, allowing atomized fuel to be discharged through the orifice and ensuring optimum engine operation. Excess fuel serves as lubrication and returns to the fuel tank through an injection leak-off line.
