怎么样增加汽车发动机的使用寿命?

来源:http://www.lutongqixiu.com/ 日期:2021-01-14 发布人:admin
1.正确起动和起步
1. Start and start correctly
发动机冷车起动时,因为温度低,机油粘度大,流动性差,使机油泵供油缺乏。同时,原气缸壁上的机油在停车后沿气缸壁下贱,因而在起动的瞬间得不到正常作业时那样杰出的光滑,致使起动时气缸璧磨损大大增加。
When the engine starts cold, the oil pump is short of oil supply because of low temperature, high oil viscosity and poor fluidity. At the same time, the oil on the cylinder wall of the original gas drops down along the cylinder wall after stopping, so it can't get the excellent smoothness at the moment of starting, which greatly increases the wear of the cylinder wall during starting.
因而,初次起动时,应先使发动机空转几圈,待摩擦表面得到光滑后再起动。起动后应怠速运转升温,严禁猛轰油口,待机油温度达到40℃时再起步;起步应坚持挂低速档,并循序每一档位行驶一段里程,直到油温正常,方可转为正常行驶。
Therefore, when starting the engine for the first time, it is necessary to make the engine idle for several circles and wait until the friction surface is smooth before starting. After starting, the engine should run at idle speed to raise the temperature. It is strictly forbidden to bang the oil port. When the oil temperature reaches 40 ℃, the engine should start again. When starting, the engine should stick to the low gear, and drive a section of mileage in each gear step by step until the oil temperature is normal.
2.正确选用光滑油
2. Choose smooth oil correctly
要严厉按季节和发动机功能要求选用较佳粘度值的光滑油,不行随意购用残次光滑油,并常常查看和坚持光滑油的数量与质量。
It is necessary to strictly select the smooth oil with better viscosity according to the requirements of season and engine function. It is not allowed to purchase defective smooth oil at will. It is also necessary to check and insist on the quantity and quality of smooth oil.
3.加强滤清器的保养
3. Strengthen the maintenance of filter
使空气滤清器、机油滤清器和燃油滤清器坚持杰出的作业状态,对减轻气缸套的磨损关重要。加强对“三滤”的保养,是避免机械杂质进入气缸,减轻气缸磨损,延长发动机使用寿命的一项重要措施,在农村和多风沙区域尤为重要。有的驾驶员为了节省燃料而不装空气滤清器是肯定过错的。
Keeping the air filter, oil filter and fuel filter in excellent working condition is very important to reduce the wear of cylinder liner. Strengthening the maintenance of the "three filters" is an important measure to prevent mechanical impurities from entering the cylinder, reduce cylinder wear and prolong the service life of the engine, especially in rural areas and windy and sandy areas. It is definitely wrong for some drivers not to install air filters in order to save fuel.
4.坚持发动机正常作业温度
4. Adhere to the normal operating temperature of the engine
发动机的正常作业温度应处在80-90℃。温度过低,不能坚持杰出的光滑,会增大气缸壁的磨损,气缸内的水蒸气易凝结成水珠,溶解废气中的酸性气体分子,生成酸性物质,使气缸璧遭到腐蚀磨损。
The normal operating temperature of the engine should be 80-90 ℃. If the temperature is too low, it will increase the wear of the cylinder wall. The water vapor in the cylinder is easy to condense into water droplets, dissolve the acid gas molecules in the exhaust gas, and generate acid substances, which will cause corrosion and wear of the cylinder wall.
试验标明,当气缸璧温度由90℃降到50℃时,气缸磨损量为90℃时的4倍。温度过高,会使气缸强度降低而加重磨损,乃可能使活塞过度胀大而形成“胀缸”事端。
The test shows that when the cylinder wall temperature drops from 90 ℃ to 50 ℃, the wear loss of the cylinder is four times of that of 90 ℃. If the temperature is too high, the strength of the cylinder will be reduced and the wear will be aggravated, and even the piston may be over inflated, resulting in "cylinder expansion".
5.提高保修质量
5. Improve warranty quality
在使用过程中,及时发现问题及时予以排除,随时更换或维修损坏和变形的配件。装置气缸套时要严厉按技术要求检验和装配。
In the process of use, timely find out problems and eliminate them, and replace or repair damaged and deformed parts at any time. The cylinder liner should be inspected and assembled strictly according to the technical requirements.
在保修换环作业中,要选用弹力适当的活塞环,弹力过小,使燃气窜入曲轴箱吹落气缸壁上的机油,增大气缸壁磨损;弹力过大,直接加重气缸壁的磨损,或因气缸壁上的油膜遭到损坏而加重其磨损。
In the operation of ring replacement under warranty, the piston ring with proper elastic force should be selected. If the elastic force is too small, the gas will flow into the crankcase and blow off the oil on the cylinder wall, which will increase the wear of the cylinder wall. If the elastic force is too large, the wear of the cylinder wall will be directly aggravated, or the wear will be aggravated due to the damage of the oil film on the cylinder wall.
