Vehicle maintenance description

Vehicle maintenance description Vehicle maintenance is to adapt to social development, as China's social development, the number of cars increases, the lack of vehicle maintenance personnel, need a group of professional, high quality service personnel. Automotive Maintenance Technology Training objectives: to develop moral, intellectual and physical development, to adapt to social and economic development needs, with good professional ethics, to understand the principles and structure of the automotive engine components, a certain amount of electrical and electronic theory and the skills and knowledge, automotive electronic control technology and traffic regulations, car fault diagnosis, testing, maintenance and other theories and skills and knowledge, has a certain public communication skills and business development capabilities of mid-level technical personnel. Employment orientation: appropriate in the vehicle inspection and maintenance, car insurance, car driving, car sales, but also engaged in business with the automotive industry and management. Research skills: electrical installation and maintenance of operating permits, operating permits welder, automotive service technician class license (permit intermediate maintenance division, maintenance division senior certificates), gas-liquid technology, electronically controlled operation certificate, the National Public English Certificate, National Computer Rank card, etc. . Main courses: electrical electronic technology and skills, fitter skills, construction and automotive engine repair, automatic transmission works and maintenance, chassis construction and maintenance, and repair automotive electrical equipment, electronic control and engine repair, automotive air conditioning theory and maintenance . Edit this paragraph common mistakes car maintenance methods 1> Remove the engine thermostat blind due to engine temperature is high and if the blind removal of the thermostat, coolant can be a cycle, can not adjust the cooling intensity, it is difficult to ensure that the engine temperature in a more appropriate work, but often in the engine work under low temperature, resulting in decreased engine power, accelerating wear and tear, increased fuel consumption. If the engine thermostat failure repair or replacement, the engine temperature is higher, it should repair other parts of the cooling system can not remove the thermostat. 2> high engine temperature are afraid that some people are not afraid of driving with low engine temperature low fear high fear. In fact, the engine temperature is low is also a great danger. Should be used according to instructions provided for the normal car driving temperature, in order to ensure the engine's life. 3> the better the pump fan belt tightening belt tightening is not possible. Not only will it stretch the belt too tight or broken, shorten the life of the belt, but also because of excessive tension, causing the generator shaft, pump shaft and bearing deformation of bending the early damage. Automotive engine fan belt tightness should meet the technical requirements, the normal deflection of the belt assembly 10-15mm is appropriate. 4> use the engine idle speed with idle heating temperature, due to low speed, machine lubricating oil pump can not quickly be pressed into the surface of the lubrication, oil is also low, the engine friction of moving parts in the dry or semi-state friction work; poor fuel atomization due to low temperature, so that unburned fuel (mixture) into the crankcase, washed away the oil film on the cylinder wall, will accelerate the mechanical wear and tear. So, after a few seconds the engine starts, the application of fast idle temperature (in modern cars are fast idle on a dedicated device, machine temperature rise, it will automatically adjust to the idle state), to improve engine lubrication. 5> roasted with a blowtorch blowtorch baked with oil at the end of the oil at the end of winter, not only will the oil additive in the chemical changes, loss of the original performance, but also the oil cement, oil at the end of deformation, can cause fire. The best approach is based on local selection of winter minimum temperature compatible oil. In localities where conditions permit, it is best insulation to vehicles parked in a garage facility. The removal method is more advanced ultrasonic spray method and the removal of nuclear clearance method, but used the most, the easiest way is to remove the physical removal and chemical methods. These two methods can be used along.
