Common Engineering Machinery Engine Failures and Solutions

Engineering machinery engines may encounter some failures after prolonged use. Understanding these common failures and their solutions can help you quickly diagnose and fix problems, thereby extending the equipment's lifespan. Here are several common engine failures and their solutions:

1. Engine Starting Difficulty

• Causes: Possible issues with the fuel system, insufficient battery power, or ignition system failure.

• Solutions: Check if the fuel filter is clogged, ensure the battery is fully charged, and inspect the spark plugs and ignition coils for proper functioning.

2. Engine Power Loss

• Causes: Possible clogged air filter, fuel injection system failure, or insufficient cylinder pressure.

• Solutions: Clean or replace the air filter, inspect the fuel injection system, and measure cylinder pressure for necessary repairs.

3. Engine Overheating

• Causes: Possible cooling system failure, insufficient oil, or clogged radiator.

• Solutions: Check the coolant level, ensure sufficient oil, and clean the radiator.

4. Engine Abnormal Noise

• Causes: Possible wear of pistons, connecting rods, or crankshaft bearings.

• Solutions: Inspect and replace worn pistons, connecting rods, or crankshaft bearings.

Preventive Measures:

• Regularly change oil and filters.

• Keep the cooling system clean.

• Regularly inspect the fuel and ignition systems.

Extending Lifespan:

• Regularly maintain and service the engine.

• Use high-quality engine parts, such as engine pistons, cylinder liners, and piston rings produced by Quanzhou Helong Machinery Parts Co., Ltd.
