In the desert area of North China, sand and wind are very serious. When driving in desert area, because of high altitude, low air pressure, thin air, strong wind and sand, loose roads and large rolling resistance, the tire is easy to slip and turn difficult. At the same time, the wind resistance is big, the power loss of the car is great, the engine is overloaded, and it is easy to overheat. The air filter is easy to block, and the intake resistance is large, which leads to the decrease of the aeration of the engine, the abnormal combustion, the decline of power and economy, and the poor reliability.

1) increase in intake system resistance

When the engine works, the cracks between the air at great speed from the air cleaner cover and body into larger particles of dust and downwards, with big inertia, rushed to the oil level, oil is adhered to the lighter dust with the air flow to the steering filter, the filter is adhered to the air in the dust filter go to 95%-97%. The dust attached to the filter core is gradually returned to the oil bottom due to the cleaning of the oil particles carried by the airflow. Severe sandstorm, dust particles is larger, the filtering efficiency drops, dust blocking filter, air resistance increases, inflation decreased.

2) aggravation of engine wear

The sand dust through the air intake system or crankcase vent into the engine, the valve and valve seat, the cylinder wall and piston ring wear, oil pollution, oil deterioration, increase mechanical wear, shorten the service life.

3) shortening the use period of air filter cartridge

In general, every 1200km air filter in the car should be cleaned and maintained every time. But in the case of severe sandstorm, car every working day after closing the car, should be Baotou beiben heavy truck parts filter out, hand pat, or compressed air to the ash, paper filter is easy to damage, should replace the filter in a timely manner, to restore the function of air cleaner.

4) the oil filter is easily blocked

The dust in the air is inhaled into the cylinder by air filter. After combustion, it forms carbon deposit. Some of them enter the oil pan, which easily block up the filter and coarse and fine filter. At the same time, it will stain the oil and make the oil oxidized and deteriorate, and shorten the service life of the oil.

5) influence on the ventilation performance of crankcase

Baotou North Ben heavy truck fittings crankcase ventilation vent filter is easy to be blocked by dust and dust. The resistance increases, which affects the pressure balance of crankcase. The fluctuation of oil level in crankcase affects the normal operation of engine.

6) other aspects

Driving in the sand under the severe conditions, the battery cover vent to dust blockage, Baotou beiben heavy truck parts radiator is easy to stick, sand and dust clogging, affect the cooling effect, the engine temperature rises rapidly, even. The grease filling nozzle of the transmission shaft is also easily sticky and blocked by the dust.

The driving car in the desert area uses the desert tires, the pressure is small, the tire driving resistance is big, and the oil consumption is great. The windshield of the cab is covered by dust, the wiper is working frequently, the driver's line of sight is bad, and the operation strength is increased.
