What Is A Cummins Engine?

Cummins engines are designed and manufactured by Cummins Corporation. Cummins engines have a displacement of 1.4 to 91 liters and a power range of 31 to 3,500 horsepower. They are widely used in road vehicles such as heavy trucks, medium trucks, buses, recreational vehicles, light commercial vehicles, and pickup trucks, as well as construction machinery and mines. Equipment, agricultural machinery, ships, and off-highway equipment such as railways.

MYMRO provides various brands of engines, and engine overhaul parts such as 5.9 Cummins rebuild kit for global buyers.

Cummins engines

Cummins, the pioneer of diesel engine vehicles, was founded in 1919 and is headquartered in Columbus, Indiana, USA. Cummins is the world's leading manufacturer of power equipment, and one of Cummins' most popular engines is the 5.9-liter inline-six engine used in the 1988 Dodge Ram light-duty pickup.

Pros and cons of Cummins engine

• Pros:

1. Fuel efficiency: Originating from the advanced design and sophisticated manufacturing of Cummins in the United States, fuel consumption is much lower than that of similar products.

2. Strong power: The design of the wastegate valve makes the low-speed performance perfect and the power performance better.

3. Excellent reliability: The cylinder block and cylinder head adopt an integrated design, which prevents water leakage and oil leakage, and has more than 25% fewer parts than other similar products. The failure rate is greatly reduced.

4. Lower maintenance cost: Fewer parts and lower failures in use greatly reduce the comprehensive maintenance cost of the engine. The maintenance time is saved by more than 50% compared with other similar products.

5. Excellent cold start performance: Equipped with air intake electric preheating setting and 6.6KW high-power starter, which completely improves the cold start of the engine.

Cummins' emission control technology can be perfectly matched with the engine life cycle and the complete vehicle so that customers can obtain the best economic benefits.

• Cons:

The cost of Cummins engine accessories is very high. Sometimes when the car is just started, there may be slight blue smoke.

Cummins engine rebuild cost

In most cases, It will take $4,500 to $10,000 for a 5.9 Cummins rebuild depending on the condition of the gas tank cover, tank body, crankshaft, etc.

How long does a Cummins engine last?

• As the saying goes, "three points quality seven point maintenance". In fact, any machine depends on good maintenance. The service life of Cummins engines is determined by the oil used. Generally, it needs to be maintained once after about 5,000 kilometers of use. If you use fully synthetic oil, it will last longer.
• The first thing to pay attention to for a new car is the running-in of the cylinder block because the surface of the cylinder block looks smooth, but it is actually uneven on the microscopic level. In addition to regular oil replacement, new cars must also pay attention to the fact that the new car cannot bear large loads.
• Clean and replace the air filter in time to ensure that the intake air in the cylinder is clean. The function of the air filter is to filter and purify the dust entering the air. With the reciprocating movement of the piston, the dust is like sandpaper rubbing against the cylinder body, which will quickly wear the surface of the cylinder body, which will easily cause black smoke, oil leakage, and even cylinder scuffing, etc. Fault.
• The air filter needs to be cleaned every 1,000 kilometers (you can use high-pressure air to blow off the dust on the surface), and it is best to replace it every 2,000 kilometers (if the road is dusty, you can shorten the cleaning and replacement cycle), you must pay attention to the replacement of the air filter quality, it is recommended to use original products.
• Keep the battery fully charged. When the motorcycle is running, it will automatically charge the battery. If the motorcycle runs for a short distance for a long time, the performance of the battery will decrease due to insufficient charging for a long time. In severe cases, the battery will be scrapped. At this time, a special charger is required to properly charge the battery.
