Mitsubishi K3M Engine: Specs, Configuration, Oil, and Service Intervals

Mitsubishi K3M Engine Specs

The Mitsubishi K3M engine is a compact and efficient diesel engine that is commonly used in various applications, including small industrial machinery, agricultural equipment, and generators. This article will provide an overview of the engine’s specifications, including its configuration, oil specifications, and service intervals.

Engine Configuration

The Mitsubishi K3M engine is a three-cylinder, water-cooled diesel engine. It features a vertical, in-line arrangement of the cylinders, which helps in reducing the overall size and weight of the engine. The engine has a displacement of 1.5 liters, with each cylinder having a bore of 78 mm and a stroke of 92 mm. This configuration ensures a good balance between power output and fuel efficiency.

Engine Oil Specs

Using the right engine oil is crucial for the proper functioning and longevity of the Mitsubishi K3M engine. The engine requires a high-quality diesel engine oil that meets the specifications outlined by Mitsubishi. It is recommended to use an oil with a viscosity grade of SAE 15W-40, which provides excellent lubrication and protection for the engine components.

Additionally, the engine oil should meet the API (American Petroleum Institute) classification of CF or higher. This ensures that the oil has the necessary additives to prevent wear, reduce deposits, and maintain the engine’s cleanliness. It is important to check the engine oil level regularly and change it at the recommended intervals to ensure optimal performance.

Service Intervals

Regular maintenance and servicing are essential to keep the Mitsubishi K3M engine running smoothly. Here are some recommended service intervals for the engine:

1. Oil Change: The engine oil should be changed every 250 hours of operation or every six months, whichever comes first. This interval may vary depending on the operating conditions and the quality of the oil used. It is important to follow the manufacturer’s recommendations for oil change intervals.

2. Oil Filter Replacement: Along with the oil change, it is recommended to replace the oil filter. The oil filter helps remove contaminants and impurities from the engine oil, ensuring clean lubrication. The oil filter should be replaced at every oil change or as per the manufacturer’s guidelines.

3. Air Filter Replacement: The air filter plays a crucial role in preventing dust and debris from entering the engine. It is recommended to inspect and clean the air filter every 100 hours of operation or as needed. If the air filter is damaged or excessively dirty, it should be replaced to maintain proper engine performance.

4. Fuel Filter Replacement: The fuel filter is responsible for removing impurities from the fuel before it reaches the engine. It is important to replace the fuel filter every 500 hours of operation or as recommended by the manufacturer. A clogged fuel filter can restrict fuel flow and affect engine performance.

5. Cooling System Maintenance: The engine’s cooling system should be inspected regularly for any leaks or coolant level issues. The coolant should be replaced as per the manufacturer’s recommendations to prevent overheating and ensure efficient engine operation.

By following these service intervals and using the recommended engine oil and filters, you can ensure the longevity and optimal performance of your Mitsubishi K3M engine.

• Regularly check the engine oil level and change it at the recommended intervals.
• Replace the oil filter with every oil change.
• Inspect and clean the air filter every 100 hours of operation or as needed.
• Replace the fuel filter every 500 hours of operation or as recommended.
• Maintain the cooling system and replace the coolant as per the manufacturer’s guidelines.

In conclusion, the Mitsubishi K3M engine is a reliable and efficient diesel engine that offers excellent performance in various applications. By following the recommended service intervals and using the right engine oil and filters, you can ensure the longevity and optimal functioning of your Mitsubishi K3M engine. Regular maintenance and care will help you get the most out of this powerful engine.
