China Cummins Engine 2

Advantages of Cummins engine:


1.Fuel-efficient

The advanced design and excellent manufacturing of Cummins makes the fuel consumption much lower than similar products.

2.Strong power

The design of exhaust bypass valve makes low speed performance more perfect and power performance better.

3.Excellent reliability

The cylinder block and cylinder cover adopt integrated design to prevent leakage and oil leakage.  The parts are more than 25 % less than other similar products, and the failure rate is greatly reduced.

4.Lower maintenance costs

The low number of parts and the low failure rate make the comprehensive maintenance cost of the engine greatly reduced. Maintenance time is more than 50% less than other similar products.

5.Excellent cold boot performance

Equipped with the intake electric preheating setting and the 6.6kw high-power starter, the engine has been completely improved in cold start-up performance. It has passed the verification of the extremely low temperature of minus 36 degrees of China's Arctic Village - Mohe.

Disadvantages of Cummins engine:


The cost of the Cummins engine parts is very high, and sometimes there is a slight blue smoke when the vehicle is just started. After the engine has been used for a long time, there may be a phenomenon that the engine may be unable to fire.

Precautions for starting Cummins engine

1.The Cummins starting machine does not operate for more than 30 seconds at a time. The time interval for restarting is 2 minutes.

2.The lubricating oil pressure should reach 70KPa within 15s after starting, otherwise the oil surface should be checked immediately.

3.After starting, the idle speed can be increased by 3-5 minutes, otherwise the bearing bush will have insufficient oil supply.

4.The idle speed should not exceed 10 minutes, otherwise there will be undesirable phenomena such as carbon deposits in the combustion chamber and oil leakage from the Cummins engine supercharger.

5.The water temperature of Cummins engine should not be lower than 60 °C, otherwise the fuel will enter the oil and destroy the lubrication.

6.After starting in winter, keep idle until the water temperature gauge needle rotates or enters operation after 10min. Observe the water temperature gauge and note whether the oil pressure gauge meets the requirements. Be sure to use a volumetric sprayer when using an auxiliary starter in winter.
