Speaking of engine maintenance，Maintenance instructions in the user manual of each car，After buying a car4SThe store will also inform you regularly or regularly.，Although I usually receive these instructions or reminders，Here，Let us reiterate the importance of automotive engine maintenance。
If you want to do a half-level，We must master the maintenance points
In addition to some power drivers Most of Modern Motors are driven by engine，Engine is called car“heart”，Continuous output vehicle power，How to keep this heart，This is related to the quality of the entire vehicle，What is important in engine maintenance?？Understand this，In order to make engine maintenance more effective。
1。 Please pay attention to grinding and using the engine，Whether it is a new engine or a maintenance engine。After the specification is running, it can be in normal operation.。
2。 During use，Check if the fastening components of the engine are affected by vibration impact and uneven load。Bolts and nuts are easy to loosen，Carefully check and tighten，To avoid damage to machine parts。
Valve clearance Valve timing Oil supply advance angle， Fuel injection pressure And the ignition timing has been checked and adjusted in time。To ensure that the engine is always in good technical state，Save fuel，Extended service life。
3。 Keep oil， Sufficient water and gas keep your body clean。
4。 Regular observation and inspection，If you find a fault， Should be eliminated in time； The engine must be completed to maintain a good technical state of the machine.。
Keep your body clean
Editorial summary：Although the engine is a complex organic whole consisting of many systems，but，Just master the above points，Engine maintenance is more effective。The key to caught the problem this time，Avoid you don't know where to start maintenance engines，no idea。In the future， Engine maintenance will become a goal，Accurate and efficient。
The relationship between seven bad habits and engine maintenance
said with no exaggeration，Car engine is called a car“heart”。The car engine is constantly transmitting power to four wheels like a human heart.。In order to make the car quickly。But some owners tend to make some problems，as a result， Our car is easy to appear“heart disease”。
1。 According to the statistics If the engine is not maintained as planned，Vehicle failure of vehicle maintenance is subject to total failure rate50％。visible，Engine maintenance plays a crucial role in extending vehicle life。
2。 Engine engine oil deterioration and oil filter。 The function of the oil is lubricating part and cools the engine。The engine is easy to degenerate due to high temperature，Oil filter is used in impurities in the filter oil，Engine Long-term operation will produce more iron filings and other impurities。Each oil filter filter is easy to block，in this way， It greatly reduces the protection and heat dissipation effect of engine oil to the engine，therefore， Regular replacement oil and filter are critical to the engine。
3。 Air filter blocks the engine's fuel combustion，Need to clean the air。therefore，Highlight the effect of air filter，If you travel in the dusty environment for a long time，It will block the air filter，therefore， Air filter should be replaced regularly。In order to make the engine“Breathe”More stable。
4。 Intake pipe dirty。 The engine consists of air cleaner components and intake pipes.。If the vehicle is often driving in dust，Areas where air quality is poor, you should clean the intake pipe，Ensure smooth cleansing。To ensure the normal operation of the engine。
5， Excessive crankshaft oil during engine operation，High pressure unburned gas acid， moisture， The sulfur and carbon oxide in the combustion chamber enters the crankcase through the gap between the piston ring and the cylinder wall.。Mixed metal powder produced with parts wear，Sludge。A small amount of soil can be suspended in the oil，But when the oil is large，It will be separated from oil，Clogging filter and oil hole，Causes of engine lubrication difficulties，Extension of engine wear，In addition，When the engine oil is oxidized at high temperatures， Will produce paint film and carbon and stick it on the piston。Increase engine fuel consumption，If the power drops seriously Piston ring is stuck，Cylinder is pulled。
6。 Fuel system maintenance。 Fuel supplies to the combustion chamber through the fuel path for combustion。Inevitably form colloids and carbon，Deposition in the oilway Injector and combustion room，Interfering fuel flow，Destroy normal air-fuel ratio，Fuel atomization，Inspiration， Burst Idle speed is unstable and unveiled。
7。 Cooling system is not good。 rust， Scales and scale on the radiator limit the flow of cold liquid。Reduce heat dissipation efficiency，Cooling system is not good，Leading the engine overheating，Even cause damage to the engine。Therefore, rust and scale is required regularly.，Engines can not only work normally，And can extend the overall life of the radiator and the engine。
Engine branch system needs to maintain
Engine is the heart of the car，This heart is divided into multiple branches，Only the organic binding of these systems can make the engine run normally，Their quality directly determines the operating efficiency of the engine，It also determines the overall life of the engine to affect the life of the entire vehicle.。The maintenance of these systems has become the weight of daily maintenance.，Can not be ignored。
Engine intake system（From right to left：Air filter elements and intake pipes in the intake port）
1。 Intake system engine by air filter（Air filter）Composition with intake pipe。According to usage，Regularly clean air filter filter and intake pipe。Make sure the engine air intake cleans clean，In order to make the fuel more burned more，Improve engine efficiency，Reduce the production of carbon。
exhaust pipe
2。 The daily maintenance of the exhaust system is mainly to check the sealing of exhaust pipe interface pads.。Whether the exhaust pipe has external damage，Whether the exhaust is smooth，The exhaust pipe is fixed firmly。
3。 Maintenance of the fuel supply system includes regular replacement of gasoline filter。Cleaning injector and oil supply pipeline。
4。 In addition to maintaining the lubrication system， Regular replacement oil and oil filter（Oil filter filter）。Also check the ventilation of the crankcase and clean the oil bottom case regularly。In addition to lubricating the engine oil entering the engine，It can also help seal，Cooling system，In addition， The oil also has a clean role。
Engine cooling system（Cooling fan and cooling tank）
5， Cooling system cooling system is an important part of the engine。The cooling system is to ensure the entire engine at a constant temperature.（80?90℃）Under normal work，Circuit combustion generated heat，During the car through the water tank radiator，The rotation of the fan and the air flow will naturally1/3Gas emissions into the atmosphere。Good antifreeze has antifreeze， Cooling and corrosion，Prevent scales from deposition and fouling，therefore， Even not winter，Also stick to the use of antifreeze。Only in this way，Can protect the inside of the heat radiator，Keep the coolant circulation system，Improve heat dissipation efficiency。Antifree fluid usually replaces once a year，Protection and expansion cooling system。
Editorial summary：The engine is an organic whole consisting of various systems.。Each system performs its responsibilities，Make sure the engine is working properly，Any system problem may cause the entire engine to stop running。therefore，We maintain these systems of the engine，This is the weight of daily maintenance work.。We must pay special attention。
TEngine stronger maintenance principle
Petroleum resources are non-renewable resources，In the era of increasing oil resources，People use the car in the direction of energy saving and reducing consumption。therefore，Now many manufacturers have launchedTModel，Is a model with a turbocharged engine，Such engine displacement is small，Low oil consumption，Energy-saving and environmental protection is welcomed by car manufacturers and consumers。With the support of the government's purchase tax policy，Although the turbocharged engine has many advantages，But its maintenance is more complicated，Cost will also be slightly higher than self-exploration。then，Let us talk about the use and maintenance skills of turbocharged engines。
Turbocharged car
1。 Don't catch fire Especially in winter。The turbocharged engine should be empty to a time purpose is to allow the boost rotor to use oil to carry lubrication bearing before running at high speed.。therefore，Do not stepping on the throttle when you just start the pedal。In order to prevent damage to the turbocharger。
2。 Turbo pressurized engine is running high speed，Unable to stop running now，Before shutting down，It should be idle3minute。Since a part of the oil is supplied to the turbocharger rotor bearing for lubrication and cooling when the 易彤破壁机故障代码 engine is running。at this time，The engine suddenly stopped and the oil pressure drops rapidly to zero，High temperature of the turbine portion of the turbocharger to the middle，The heat in the bearing housing cannot be taken away quickly，Simultaneously， The supercharger rotor is still rotating at high speed under the action of inertia，This can cause oil overheat that is rearing in the turbocharger.，And damage bearing and shaft。in particular， Avoid suddenly turn off after the accelerator pedal。
Turbocharged engine
3。 Check the operation of the turbocharger before and after leaving the car.，Should check the connection of the airway，Prevent loose，The supercharger fault is caused by the air short circuit in the drop and the air in the cylinder.。When the oil suddenly dirty，Crankcase pressure rises rapidly，When oil consumes too much，Turbo pressures may have faults，Must remove the check。
4。 Keep air filter cleaning。 Please clean the air filter in time，To prevent dust and other impurities from entering high-speed rotating compressor impeller。Causes the speed of rotation or severe wear of the bushing and seals。
How to work with turbocharged engines
Editorial summary：Although the turbocharged engine has many advantages，Small displacement low fuel consumption strong power。But if you get You must lose。Its mechanical operation is more complicated，therefore， We must be more stringent and cautious，The required fuel mark also increases，Maintenance costs will increase accordingly，As long as you have the above and maintenance skills of the above turbocharged engine，Will extend its service life。
