Automobile Power System Key working principle

The electrical power used in automotive electrical equipment is a DC power source, which comes from batteries or generators. The electrical system, which is connected by batteries, generators, regulators, charging status indicating devices, switches and wires, is called a power supply system (referred to as a power supply system).UCANDAS VDM2

The work of the automotive power systemThe battery and the generator in the MB SD Connect C4 power supply system are working in parallel. When the engine is in normal operation, the generator is powered by the generator and charged to the battery. At the time of starting, the battery supplies power to the starter. As the generator is driven by the engine through the drive rotation, when the engine speed changes, the generator output voltage will change. To meet the requirements of automotive electrical VAS5054A equipment and battery charging constant voltage, the power system are set within the voltage regulator to ensure that the generator output voltage stability in a certain range, to prevent the voltage fluctuation is too large and burn the electrical equipment. The charging state indicating means indicates the charge / discharge condition of the battery.

The layout of automotive power systems   VVDI2
At present, the power system on the car can be divided into 12V power system and 24V power system, and the general use of alternator and electronic regulator.Key Programmer
According to the electronic regulator installed in different ways, the power system layout can be divided into separate and integral two.key cutting machine
The distinctive features of the integral alternator power supply system are:
There is no longer a wire connection between the alternator and the voltage regulator. The system line is greatly simplified and the failure rate is greatly reduced. But the system failure can not quickly diagnose the failure of the car parts
CK100 Key Programmer
In recent years, with the people riding comfort, fuel economy, environmental protection requirements of the increasing, new electrical installations in the car has been widely used, the proportion of automotive electronic accessories increased significantly, such as a variety of Electronic control system (electronic control jet, electronic control automatic transmission, electronic control suspension), cruise control, car computer network.Diatronik OBD Tool

Some electromagnetic or electric actuators have also gradually replaced the hydraulic drive and pneumatic actuator, which greatly increases the load on the electrical system, which requires the car's power system to provide higher power.

How to detect Auto GND badness?

01 starter operation, if the battery grounding wire temperature is too high, even at the end of the phenomenon of red on the ground, indicating that the battery grounding wire contact bad.X431 Tool

02 in the case of non-charged measurement of the resistance value of the ground point, that is, with a multimeter of a table pen reliably connected to the wire, Yanhua Digimaster 3 another pen and metal parts of the body connected to measure the resistance between them, if there is resistance, The VXSCAN EL-50588

03 using simulated vibration method. For the suspected parts, you can in the vertical direction and horizontal direction gently shaking the line, to simulate the state of TOYO KEY OBD II vibration when driving the car, while observing the reaction of the relevant parts to determine whether the ground with Weld, loose, poor contact or wire break phenomenon.Autel MS906  If you shake a ground line when the fault reproduction or failure disappeared, indicating that the bad place where the ground here.

04 When the circuit is energized, the voltage drop of the tapping point is measured with a multimeter. The reading should be as low as possible (close to 0). The method is to start the engine,Xhorse Condor XC-002 the use of multimeter DC voltage block, the red pen touch the generator output, black pen touch the engine body, measured a voltage value; and then the red pen touch the output of the generator, black pen contact The metal part of the frame, and then measured a voltage value. Under normal circumstances, these two voltage values ​​should be consistent. If the Autel MS908P former value is large, the latter value is small, a difference of 0.5V or more, indicating the existence of more than 0.5V voltage drop, it is by the engine body and the frame caused by bad grounding.

Detection of a point of the situation, it should be measured at the point of the power supply voltage, try not to measure the point of the negative resistance of the power supply, this is because the multimeter itself has a certain internal resistance, measured the resistance value of the larger error.

How to clear the Auto engine carbon deposition

First, the risk of carbon deposition OBD2
 (1) pre-combustion chamber to start the nozzle hole with carbon deposition will plug the nozzle make the engine start difficult; 
(2) fuel injectors gather carbon  easy to stuck fuel injectors  cause the engine to stop the cylinder run or suddenly turn off;Carprog 
(3) the top of the piston carbon deposition will form a lot of hot surface cause premature combustion and deflagration  shorten the engine life;X431 TOOL 
(4) Cylinder head with carbon deposition  will reduce the engine cooling effect the engine's power and economy are greatly reduced;5054A 
(5) spark plug too much carbon  in the fuel after the wet  equivalent to the spark plug between the electrode shunt resistance caused by spark plug leakage can not work;Autel DS808 
(6) piston ring groove carbon deposition  will make the piston ring backlash, backlash smaller _ even no gap; cause the piston ring cement loss of elasticity even breaking the piston ring and pull the cylinder;PS100
 (7) valve duct and valve stem carbon deposition will accelerate the valve stem and valve duct wear and tear will even cause the valve stem in the valve tube within the hair astringent and stuck;
 (8) valve and its seat on the working surface of the accumulation of carbon will cause the valve closed lax and leakage _ engine difficult to start, work weakness and easy to burn the valve and other undesirable phenomena.automobile repair guide

Second, the formation of glial and carbon depositionFuel in the storage, transportation process _ prone to oxidation reaction _ the formation of colloidal substances. These colloidal substances according to the solubility of gasoline can be divided into: soluble and insoluble in the gum.Auto key programThe insoluble gel, also known as the sediment _ it joins the fuel tank with the fuel tank _ will be attached to the fuel filter _ plug the filter medium _ to reduce the amount of oil _ to make oil shortage _ fuel atomization bad _ Resulting in flammable mixture dilution _ engine power and economic decline.The sol-gel enters the combustion chamber and the gasoline together. After burning, it will form many hard deposits on the intake valve, the piston top, the piston ring groove, the combustion chamber, the spark plug and other parts. Acceleration is not smooth _ idle instability _ stall, jitter, knock and a series of failures.When the engine is working, it is not possible to burn 100% of the oil that is fueled or flipped into the combustion chamber. The unburned part of the oil forms hydrochloric acid and resinous colloids under the catalysis of high temperature and oxygen. Adhesive to the surface of the part. The role of high temperature and further MASTER MST-500 concentrated asphaltene and oil coke and other complex mixture of the so-called carbon. Vehicle driving _ because the fuel in the glial and combustion after the formation of carbon deposition caused by the failure is more common _ great.

Third, how to remove gum and carbon deposition Benz IR Key Program 
In order to eliminate these failures, it is necessary to remove the coke from carbon and gasoline. However, many of the current methods used in the garage are to be cleaned and then cleaned. This method is not only time consuming and costly. It is not ideal, and it is not possible to remove the glial from the tank and the tank. It is also not suitable for today's car engines because today's car engines are assembled according to stringent process requirements in a clean, dustproof and ultra-quiet environment. After cleaning and re-assembly _ its power, sealing performance can not be compared with the original performance.It is no longer necessary to worry about this because it is only necessary to add a certain percentage of the fuel system in the fuel tank cleaning agent _ can solve the problems caused by carbon deposition. Fuel system cleaning protectors are gasoline and diesel general products , Designed specifically for the EFI car design, there are gasoline engine dedicated _ in the car can automatically remove the hard carbon deposition _ the engine's performance back to normal _ no longer by the disintegration of the pain _ can completely remove the carbon _ Reloading driving pleasure.After using this product to clean the coke, you should replace the petrol filter, because the jelly and tubing in the glial material and sediment are gathered in this _ if not timely replacement _ may cause poor fuel supply.
