Tips for maintaining Jinan 12V190 Diesel Engine

When operating a Jichai 12V190 diesel engine, it is essential to follow strict precautions to ensure optimal performance, longevity, and safety. Below are key guidelines to observe:

1. Read the Manual and Understand the Engine

• Carefully read the operation manual to familiarize yourself with the structural features and operation procedures of the Jichai 190 series diesel engine.

2. Use the Recommended Fuel and Engine Oil

• Always select fuel and engine oil according to the specified types and brands in the manual.

• Ensure the fuel storage container is clean. Precipitate and filter the fuel before use.

• Maintain cooling water quality and add anti-rust emulsion as required.

3. Follow Technical Maintenance Regulations

• Implement technical maintenance according to the prescribed cycle.

• Perform routine inspections and preventive maintenance to avoid engine failures.

4. Proper Cold Start Procedure

• After a cold start, do not load the engine immediately.

• Wait until the cooling water temperature reaches above 40°C before gradually applying a load.

5. Avoid Prolonged Idling

• Do not run the 12V190 diesel engine at idle for extended periods without load to prevent engine damage.

6. Monitor Engine Operation and Keep Records

• Continuously monitor the operating status of the diesel engine.

• Maintain operation records as required.

• If any abnormalities occur, identify the cause immediately and take corrective action.

• In case of automatic shutdown, determine the cause before restarting.

7. Avoid Unauthorized Disassembly

• Do not disassemble engine components, especially parts related to the fuel supply system and supercharger, unless necessary.

• If disassembly is required, follow the prescribed procedures and reinstallation guidelines.

• Parts affecting technical parameters (e.g., valve clearance, fuel supply advance angle) must be rechecked and adjusted after reinstallation.

• Do not unseal any factory-sealed parts during operation.

8. Inspect Before Using a Stored Engine

• If using a new engine that has exceeded its storage period or reactivating an old engine, perform a full inspection before installation.

• Open the Jichai 190 cylinder head, inspect the cylinder liner, and rotate the supercharger turbine to check for abnormalities.

• If rust or other issues are found, conduct necessary maintenance before use.

By following these precautionary measures, you can ensure the safe, efficient, and long-term operation of your Jichai 12V190 diesel engine.
