subject: About Cars And Then Solve The Problem [print this page] The basic concept of vehicle breakdown, it is the car part or total incapacity of the phenomenon, including the car can not travel, non-functional requirements and performance specifications down to the outside. Automotive fault detection techniques are commonly used to launch x431, lexia3, mb star. Car trouble, mostly in traffic on the way, if away from the base warranty, with fault barely moving, it would have serious consequences. Once the car in a deserted place "anchor", not only failed to detect and repair equipment available, and even room and board is also a problem. At this point, even if the connection to the resident for help, they must explain what type of work to be sent, with what tools and materials to come. Do this, we must first identify the damaged vehicle parts and damage. So easy to learn and master judge and troubleshooting techniques for improving the skills of each driver and qualified personnel are essential.
First understand the fundamentals of the structure of motor vehicles. Note that the detection technology, such as launch x431. Car is composed of nearly ten thousand parts of a whole. Determine vehicle faults, first of all should be familiar with the vehicle's structure and working principle, and then combined with the analysis of symptoms, examination, can rapidly and accurately detect the fault. For example, only understand the overhead valve type engine oil road construction, oil in the engine when the radiator appears to be associated with cylinder head, cylinder body and the water jacket between the oil channels or cracks caused by trachoma; only about two- circuit brake system structure, when the brake failure of a bridge, would think of moving control valve which may be relevant; Again, only by understanding the construction of fuel system, carburetor float chamber when no oil, can Manifold block section soon find out, leaking or damaged parts. Therefore, to rapidly and accurately determine fault, we must study aspects of vehicle construction and work done on principle. This can be handy to judge fault, do not take detours or less.
Second, consider the fuel, lubricating oil quality. Select the appropriate fuel, lubricants car prerequisite for normal driving, use of non-standard, do not meet the requirements of fuel, lubricating oil, is one of the reasons causing failure. For example, below the grade of gasoline, engine power will decrease the engine running will emit a very unpleasant odor, the combustion chamber and inlet and outlet channels of serious carbon deposition phenomenon. Again, the engine used in summer below the label of the oil, because oil than thin, easy to miss from the parts with the gap Department, resulting in low oil pressure, resulting in burned bush. Again, you should use hypoid gear oil reducer, the inclusion of regular gear oil, gear will be damaged very quickly.
Third, we must consider the environmental conditions. In determining the failure to consider the impact of environmental conditions. We can use the detection technology has lexia3. For example, a large car in the dusty environment, travel, air filters it is easy to plug in the fog or high temperature environment, traffic, filter paper pores prone to clogging, the filter can significantly reduce life cycle. If the car is moving, the engine power down there, gasoline consumption increased, exhaust black smoke, we should focus on considering the air filter plugging, reducing the amount of air to enter, causing the mixture too thick due. At this point, remove the air filter, if the symptoms disappear, it proved to be such a failure. Again, cars driving in hot weather, if there is not oil petrol pump phenomenon, we must first consider whether the oil supply system to produce air resistance caused because, if a short break or a wet rag to cool on the fuel pump after the symptoms were relieved or disappear, it indicates judicious.
Again to consider the impact of human factors. Car warranty process, as the operator unskilled or negligent, removable parts not noticed when the assembly sequence and direction, it could have the adverse consequences of the functioning parts, resulting in human error. In determining such failure to recall or ask at the security process, combined with vehicle structure principle of cause and site can be wrong in order to successfully detect faults, another example, a driver with high pressure water washing, the engine can not be launched. Often this is to splash water on parts of ignition system caused the short circuit caused by, especially in high-voltage circuit, which is more sensitive, we should focus on checking the ignition coil, distributor cap, spark plug of the terminal on the power lines and if there is water. Alternatively, the hot car suddenly a cold shower, distributor cap inner walls of the condensation of many small drops of water easily, so that ignition disorder. At this point, as long as the water droplets with a dry cloth to dry, failure can be ruled out.
Finally, note that checks the order. Looking for failure, not able to make accurate judgments, according to the rational order to be checked. Should generally follow the exterior to interior, from simple to complex, small projects first, then the order of major projects, for example, two adjacent cylinders of a motor does not work, suspected to be washed out due to cylinder head gasket. Remove the cylinder head blindly, we found a good cylinder seal, the cylinder head gasket fitted good test, they find the two-cylinder high-pressure sub-system connected with each other the wrong line. Failure to grasp the normal order of examination can save time and effort, do not walk or less detours. The mb star detection method is very effective.
