What parts need to be replaced for automobile engine maintenance? How often do you maintain it? How much will it cost?

The car needs maintenance once when it travels more than 5000 kilometers. In the process of maintenance, the parts that need to be replaced include pistons, valves, valve guides, crankshafts, etc. Generally speaking, the cost of a maintenance is 400 ~ 1000 yuan. Engine maintenance needs to replace the standard four-piece set, so that our car will be maintained once after driving more than 5000 kilometers. The main overhaul parts of engine maintenance are valves, pistons, cylinders and grinding shafts. These four parts are also the main parts of automobile engine maintenance. Generally speaking, the car is sent to the 4s factory for maintenance, and these four-piece sets will be replaced in time. Automobile engines will be inspected before overhaul, including whether the externally processed cylinder head is flat, boring cylinder, grinding valves and pistons, etc.

Motor and generator are two important maintenance objects. In terms of automobile engine maintenance, the key maintenance objects are motors and generators. These two pieces are also the power of the car. The generator needs to be cleaned in time to keep its good heat dissipation. The main maintenance is whether liquid or clean water parts enter the motor. If this happens, clean it up in time. Check whether the fuel engine will idle after starting, and monitor the running sound of the electronic engine. If there is noise, deal with it immediately. Check whether the motor vibrates violently at the rated speed. If it vibrates, it means that the motor is damaged and needs timely maintenance.

According to the nursing needs of the motor, first check whether the motor is faulty and whether it needs to be disassembled and repaired at the first time. After starting the motor, first check whether the battery works normally, and then check the voltage value to see if the specific gravity is correct. Generally speaking, 4s repair shops can find out whether there is a problem with the engine itself through acoustic detection, and then carry out maintenance.

Automobile engines should be maintained once every six months or more than 5,000 kilometers. Generally speaking, the maintenance of automobile engines needs more than 5000 kilometers or half a year. When driving over 8000 km to 1000 km, it is necessary to change the oil once. If the oil is abnormal, it will be difficult for the engine to continue running. When the engine is running, an oil film will form inside the engine oil, which can prevent the internal parts of the engine from direct contact and friction.

However, the long-term use of engine oil will lead to the deterioration of the performance of various components in the engine and need to be replaced regularly. In the process of maintenance, besides engine oil, we should also consider the filter element of engine oil, which is the main component of filtering engine oil. If the filter element is blocked and dirty after a period of use, it will also aggravate the wear of the engine to some extent.

Engine maintenance also requires cleaning daily parts. Most car owners will maintain the engine of the car after driving for half a year, in order to make the car have stronger driving force. For the maintenance of the engine, in addition to the internal parts, it is also necessary to carry out daily cleaning work on the engine components, such as air filter element, throttle sludge, carbon deposit on the injector, etc. Only by cleaning up these three daily structures can the fuel consumption be relatively reduced, the car will be relatively comfortable to drive and the road will be safer.

Among them, the air filter element ensures the heat dissipation inside the engine, and it can dissipate heat faster if it is cleaned. Too much sludge accumulates in the throttle valve, which is easy to cause air resistance, thus leading to an increase in fuel consumption. The carbon deposit in the fuel nozzle should also be cleaned regularly, otherwise the combustion chamber will produce a large amount of carbon deposit, which is very difficult to start, and may even block the gasoline injection to the extent of poor atomization effect and increased fuel consumption.

Automobile engine maintenance cost: 400 ~ 1000 yuan. The cost of maintaining the engine once is 400 ~ 1000 yuan. The main costs of weight are oil replacement, engine filter consumables and internal grease cleaning. Carbon deposition will occur in normal engine during use, which has nothing to do with direct injection in cylinder. After the engine is used for a period of time, its carbon deposition will increase. At this time, you can only drive the car to the 4s shop for professional people to dismantle the car and clean it.

According to different models, the maintenance costs are different. Generally speaking, the cost of medium-sized cars is around 400 to 600 yuan, while the maintenance cost of large cars is relatively high, about 800 to 1 1,000 yuan.

In a word, the engine, as the power device of the automobile, needs to be maintained once after driving more than 5000 kilometers or half a year. The cost is about 400 to 65,438+0,000 yuan, which varies according to different models. Car owners and friends should pay attention to their car engine maintenance in time and add an extra guarantee for their driving safety.
