What is the reason for the drainage of the Cummins 6ct engine supercharger?

1. The cylinder gasket is damaged. The cylinder head of the Cummins diesel engine and the cylinder block of the diesel engine are sealed by the cylinder gasket. The cylinder block waterway has a corresponding sealing ring in the cylinder gasket to ensure that the coolant does not leak.

2. In this case, the antifreeze enters the engine oil pan. There are several reasons as follows: 1.With cylinder liner, the cylinder liner has sand eyes. 2. The cylinder pad is damaged. 3. The cylinder head is damaged by water blocking. 4. The cylinder has sand eyes. When you remove the oil bottom shell, you can see which part of the antifreeze is leaking from.

3. The water and carbon dioxide produced by the complete combustion of gasoline. Because the temperature of the engine cylinder is particularly high, the water that has just come out of the cylinder is gaseous. However, after encountering the exhaust pipe wall with a temperature below 100℃, the water vapor condenses into water, so the exhaust pipe drips.

4. The rubber ball valve is broken, the seal is not tight, and there is water leakage. Just replace it. The rubber gasket of the drain under the ball valve is aging, the seal is not tight, and it needs to be replaced.

5. Reason: Due to the leakage of oil at the end of the supercharger, the oil is burned through the engine intake pipe into the combustion chamber. There are the following typesEnergy: (1) The oil return pipe of the supercharger is not smooth, the oil accumulates too much in the middle support of the rotor assembly, and flows into the compressor impeller along the rotor shaft.

How to return the high water temperature of Dongfeng Cummins engine 6ct300 horsepower Matter

"relatedThe content introduction is as follows: The reasons for the high temperature of the Cummins engine are: there is a lack of antifreeze in the engine cooling system, which may be leakage points in the engine, such as water pump leakage, pipe damage, water tank damage, etc.; the thermoster in the engine cooling system fails to cause the water temperature to be too high.

The failure of the thermosulator causes the engine to overheat. Thermosters are generally installed in the upper part of the engine. If the cooling water temperature does not reach a certain temperature, water cannot be delivered to the water tank. Therefore, it may be due to the thermostulator that the temperature cannot be delivered to the water tank even if it reaches the benchmark temperature, or the amount of water delivered is too little, resulting in the engine overheating.

The water tank or intercooler heat sink is blocked by mud, leaves and other debris.

The main reason for high water temperature is generally insufficient coolant or thermosulator failure. NodeThe thermos automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, and changes the circulation range of the water to adjust the heat dissipation capacity of the cooling system and ensure that the engine works within the appropriate temperature range.

120kw Cummins 6ct engine parameters

1, Cummins 120kw generator fuel tank capacity size 180L.

2. The power segment of Dongfeng Cummins is between 20kw and 200kw. Common models are: 4B9-G1, 4BT9-G1, 4BTA9-G2, 6BT9-G1, 6BTA9-G2, 6CTA3-G2. The power segment of Chongqing Cummins is between: 200kw-1350kw.

3. Technical parameters of Cummins 6ct series: power range 100 to 200Kw. The number of cylinders is 6. Air intake form, supercharged and cold. The rated power and speed are 160 kilowatts and 2200 rpm, with a maximum torque of 908N.m and 1500rpm. The displacement is 3 liters.

Cummins 6ct240 horsepower engine, medium-speed gun emits black smoke

1. The fuel supply is too large, causing the amount of oil entering the cylinder to increase, resulting in more oil, gas and less fuel combustion. Incompletely burned.

2. Excessive oil supply increases the amount of oil entering the cylinder, resulting in more oil and less gas and incomplete fuel combustion. In addition, excessive workload, poor fuel quality and low working temperature will also cause black smoke from the exhaust.

3. The main reason for the black smoke in the engine is that the mixture in the cylinder is too thick and the combustion is incomplete.
