Starting System

What does the starting system do?

The engine starting system consists of a battery, an ignition switch, a starting relay, a starter, etc. The function of the starting system is to convert the electrical energy of the battery into mechanical energy through the starter to start the engine. Storage battery refers to the general term of all chemical energy batteries that can be recharged and used repeatedly after the electricity is used to a certain extent. The reason why it can be charged is that its chemical action can be reversed after being connected to an external power supply. The ignition switch is the main circuit that can freely turn on or off the ignition coil, and it is also applicable to other electrical circuits. The starting relay controls the on-off of the electromagnetic switch circuit of the starter by the starting relay contact, and the starting switch only controls the starting relay coil circuit, thus protecting the starting switch, and there are single-connected type and compound type.
how to maintain
1. Selection of cooling water: river water with low hardness should be used, such as well water, which should be boiled and softened before use. It is best to use antifreeze.
2. Pay attention to the technical status of each part: if the radiator is found to leak, it should be repaired. If the water pump and fan are found to be oscillating or making abnormal noises, they should be repaired in time. If the engine is found to be overheated, check whether it is short of water in time, and stop it if it is short of water. After cooling down, add enough cooling water. If the thermostat is not working properly and the engine operating temperature is too high or too low, it should be repaired or replaced in time.
3. Inspection and adjustment of fan belt tightness: If the fan belt tightness is too small, it not only affects the cooling air volume and increases the engine workload, but also accelerates the wear of the belt due to slippage. If the belt tightness is too large, it will accelerate the wear of water pump bearings and generator bearings. Therefore, the belt tightness should be checked during use and adjusted if necessary. If it does not meet the regulations, it can be adjusted by changing the position of the generator and the adjusting arm.
4. Regular cleaning of scale: After the engine has been used for a certain period of time, scale will be deposited in the water tank and radiator to affect heat dissipation, so it should be cleaned regularly. The cleaning method is to add enough cleaning liquid to the cooling system, soak for a period of time, and start the engine After running at low and medium speed for a certain period of time, release the cleaning solution while it is hot, and then rinse it with clean water.
