Mitsubishi k4e engine

Types of Mitsubishi K4E engines

The Mitsubishi K4E engine is a four-cylinder, water-cooled diesel engine with a direct injection fuel system. There are two typical variations of this engine model.

• Mitsubishi K4E-1

  The Mitsubishi K4E-1 engine produces a horsepower of approximately 68 to 73 and a torque of around 114 Nm at 2,200 RPM. It was initially designed for small to medium-sized trucks and some models of agricultural machinery and equipment.

  Because of its lightweight, small size, and qualities, the Mitsubishi K4E-1 has superior fuel economy, providing the vehicle with a longer travel distance per diesel fuel volume. K4E-1 also features a quiet engine running and low vibration.

• Mitsubishi K4E-T

  Mitsubishi K4E-T is a turbocharged engine model. Mitsubishi Turbo K4E engines have a higher horsepower and torque than K4E-1. For example, the K4ET engine produces a horsepower of about 100 to 110 and a torque of around 156 Nm at 2,200 RPM.

  Mitsubishi K4E-T engines were commonly used in pickups, larger trucks, and some SUV (Sport Utility Vehicle) models. Some agricultural equipment like tractors and harvesters used the turbocharged variation of the K4E engine.

Specifications and Maintenance of Mitsubishi K4E Engines

Mitsubishi K4E engine's specifications vary depending on the particular model in which it has been used. The following are common specifications related to the K4E diesel engine.

• The engine has a capacity to generate a power of about 54 horsepower at 4,800 rpm. Some models can generate up to 61 hp.
• The cylinder block of the engine is made of iron casting. It has four cylinders and a cylinder diameter of about 3.55 inches. The cylinder length, also known as the stroke, is about 3.54 inches.

• The engine has a compression ratio of approximately 18.0:1. The ratio has a significant impact on the engine's fuel efficiency and power.
• The overall length of the engine is around 23.6 inches, with a breadth of about 26.8 inches and a height of 23.2 inches. The overall weight of the engine is around 80 kgs.

Maintenance

The maintenance requirements for the K4E engine may vary depending on the specific application and usage conditions. However, here are some general Mitsubishi K4E diesel engine maintenance tips:

• Regular oil and filter changes:

It is essential to change the engine oil and oil filter at regular intervals to maintain engine performance and longevity.

• Inspect the cooling system:

The cooling system helps prevent the engine from overheating. Therefore, it is essential to check the coolant level periodically and inspect the hoses and radiator for any signs of wear or leaks.

• Regular air and fuel filter changes:

Replacing the air filter helps ensure proper airflow to the engine, while changing the fuel filter helps maintain fuel system integrity.

• Inspect the belts and hoses:

Check the engine's belts and hoses for any signs of damage, fraying, or cracking. Replace them if any damage is detected.

• Regular inspections of the exhaust system:

Check the system for leaks or any signs of corrosion or damage. The early detection of issues can help prevent costly repairs down the road.

• Maintain proper engine alignment:

If the K4E engine is used in a complex system, it is essential to ensure that the engine is properly aligned. Misalignment can cause excessive wear and damage to the engine and connected components.

• Scheduled professional servicing:

In addition to the above maintenance tips, following the manufacturer's recommended service schedule for the Mitsubishi K4E engine is crucial. This will ensure that critical components are inspected, adjusted, and replaced as needed to keep the engine running smoothly.
