SINOTRUK HOWO 336 What is the reason for the sound of gunfire in the intake pipe?

Abnormal noise only exists when running at idle or at low speed. The reasons for the sound are: the gap between the piston and the cylinder wall is too large; the piston pin assembly is too tight or the connecting rod bearing assembly is too tight; the gap between the straight rod and its guide hole is too large; the contour of the gas distribution cam is worn; sometimes, the starting grip is loose and the pulley makes the pulley to sound (obvious when the speed changes).

First, fire the inlet pipe. The fire of the intake pipe is due to the fact that the mixture is too thin, the ignition time is too early or the valve is not tightly closed. The high-temperature and high-pressure gas in the combustion chamber rushes out and detonates the mixed gas in the intake pipe to produce an explosion. Second, the exhaust pipe is fired.

The fuel filter is blocked. As one of the "three filters" in the maintenance project, the fuel filter is generally arranged in the major maintenance. Fuel filter oneIf there is a blockage, it will cause insufficient oil supply, resulting in the mixed gas being too thin, and there will be weak acceleration, car-throtting, firecrackers and other phenomena.

There are many reasons for the fire, which may be that the mixed gas is too thick or the oil level of the float chamber is too high, and the spark plug is broken or the fire is weak. If the combustible mixture of the engine is too thick, it cannot be completely burned and will be discharged with the exhaust gas. When it encounters fresh air, it will burn again and cause an explosion.

The sound of the car engine is generally caused by the serious erosion of the working surface of the exhaust valve or the exhaust door and the looseness of the valve seat. After these situations occur in the engine, when the exhaust valve is closed during operation, the closed exhaust valve cannot completely cut off the exhaust channel.

What is the engine power of the Howo 336 dump truck?

The engine power of SINOTRUK HOWO 336 horsepower is 280 horsepower, the maximum peak torque is 1200 Nm, and the fuel economy is low.

D27 This engine is the engine produced by SINOTRUK with a displacement of 10L and a power of 270 horsepower.

The horsepower is different. 375 is 39 horsepower larger than 336, and the torque is also different. The 336 torque is about 1500~1600, while the 375 torque is about 1700~1850. Therefore, 375 can pull a lot of goods at the same speed than 336.

SINOTRUK 336 horsepower high-top valve gap

1. The valve gaps of the intake and exhaust valves are different, and the gap between the intake valves must be smaller than that of the exhaust valves. Due to different car models, yesThe requirements for the valve clearance are also different. The intake valve is generally between 15 and 20 threads, and the exhaust valve is between 25 and 30 threads.

2. Loosen all the bolts of the evb, adjust the rocker arm of the exhaust valve, and then adjust the evb.

3. According to the ignition order of the cylinder, after determining the stop position of a cylinder piston in the compression, the gap between the inlet and exhaust valves of the cylinder can be adjusted; after adjustment, the crankshaft is shaken and the valve gaps of other cylinders can be gradually adjusted according to this method.

4. Adjust the valve gap, and gently touch the valve rocker arm under the tentacle.

5. If you don't know the order, you can adopt the method of cylinder-by-cylinder adjustment to adjust the gap, that is, the inlet and exhaust valve springs of the cylinder are in the highest position (no pressure), and adjust the cylinder valve gap, and the intake valve gap is 0.40~0.45mm, and the gap of the exhaust valve is about 0.45~0.50mm.

The weight of the 336 engine of SINOTRUK

1. kilowatts. 1 horsepower is equal to 36 kilowatts, 336 horsepower is equal to 336*36 is equal to 457 kilowatts.

2. The fuel consumption of SINOTRUK Howo 336 is about 0.35 per kilometer. There is a fundamental relationship between fuel consumption and displacement, and it is also directly related to the use of the vehicle. Comparing natural intake and natural aspiration, and comparing turbocharging and turbocharging, it is found that the fundamental relationship is that the larger the displacement, the higher the fuel consumption.

3. Judging from the model, it should be 336 horsepower, and the engine power should be 336ps*36=457 kilowatts.
