Material
1. Casing: Made of ductile iron or high-strength steel (such as 20Cr) through casting and forging, possessing extremely high compressive strength.
2. Internal Components: The internal plunger, piston rings, and valves are made of high-chromium steel or carburized steel to enhance wear resistance.
3. Seals: Made of highly wear-resistant synthetic rubber or polyurethane materials to prevent high-pressure leakage.
Applicable Location
1. Installation Location: Installed on the left side of the engine, connected to the engine crankshaft via a camshaft or timing chain, and driven to rotate.
2. Common Faults: If the engine experiences difficulty starting, excessive black smoke, significantly increased fuel consumption, or engine vibration, it may be due to internal wear or leakage caused by aging seals in the fuel injection pump.
3. Repair Recommendation: Due to the complex internal structure (including timing gears, stator, rotor, governor, etc.), it is recommended to have it inspected or replaced at a professional repair shop.
YN4E130 Diesel Fuel Injection Pump BH4QT85R9 is a core component of the diesel engine fuel system, primarily used to increase fuel pressure and precisely control the injection process.
1.Boosts low-pressure fuel to high pressure, ensuring proper atomization of fuel to enhance combustion efficiency.
2.Works with electronic control systems (e.g., common rail technology) to regulate fuel injection quantity and timing according to engine operating conditions, optimizing power output and emissions.
3.Evenly distributes high-pressure fuel to each cylinder in multi-cylinder engines, ensuring smooth engine operation.
Precautions
Regularly inspect seal integrity and wear to prevent high-pressure leaks.
Use specialized tools during maintenance and maintain cleanliness to avoid damage to precision components from contaminants.
