Daily vehicle repair and maintenance

After 70,000 kilometres, the day-made vehicles require critical maintenance work, including replacement of spark plugs and gear tank oil. The role of spark plugs is to discharge high voltage power to produce a mixture of gases in the gas cylinders, of various types, including quasi-types, elasticity, etc., consisting mainly of insulations, shells, wire screws and electrodes, which require good insulation and conductivity. Vegetable tank oil, also known as gear oil, is used in gears in lubricators, brakes and differentials to prevent wear, extend useful life and increase power transfer efficiency. These maintenance projects are essential to maintain the performance of the day-made vehicles。

The 70,000 kilometres of daily-producing vehicles had to be maintained by replacing spark plugs and fuel transformers。

Introduction to spark plugs:

Car spark plugs are pulsed high voltage discharges delivered by high-voltage guidance, blasting through the air between the two electrodes of the spark plugs and generating electric sparks to ignite the gas mixture in the cylinders. The main types of spark plugs are the quasi-plugs, the diagonal pretentious spark plugs, the electrode spark plugs, the seat plugs, the polar spark plugs, the face-jump spark plugs, etc. The power of the engine is largely determined by the combination of spark plugs and ignition and oil supply systems. The main parts of the spark plug are insulation, shells, wire screws and electrodes, which must be of good insulation and heat, high mechanical strength, resistant to high temperature heat shocks and chemical corrosion, usually 95 per cent of aluminium oxide。

Description of transformer tank oil:

The gear tank is equipped with gear oil, which is called gear tank oil and is used as a moving lubricant for various gear lubricating in transformers, brakes and differentials. Teeth wear, sinter, etc. Can be prevented, with longer useful life and more efficient transmission power。
