14:13. "Eats" much, but quietly goes
If the engine is badly started, poorly pulls and spends fuels much, – the hitch can appear at all not in what first you think of. The simple, apparently, situation from the point of view of definition of the prime cause is the most artful. Many bravely begin independent search, without understanding that these manifestations can be a consequence of a number of the reasons – from elementary to rather serious. It is good if you have a car in which simple and outdated technical solutions – classical Zhiguli are used, "Muscovite" and Volga, – it is possible to address the mechanics having experience in the field of repair of similar cars safely. But having replaced the car with more modern, many motorists continue to address the same masters. And they lack courage to admit that they do not understand difficult processes in fuel systems and electronic schemes of ignition. They watch a spark at breakdown, punching at the same time transistors, isolation of windings of the reel, high-voltage wires, and "protorivy" conducting paths on covers and runners of the distributor. Without solving a problem, such mechanics exhaust "disease" inside. And as a result the owner all the same goes to professionally trained engineers. But "treatment" of the car is already considerably complicated. Experts quite often get into a situation when after long work even with the help of devices nothing manages to be understood. And only later time it becomes clear that previous "clever man" tightened up jets in the carburetor or twisted everything in an injector, and at the end broke its tightness or burned pressure sensor. The list of the possible reasons resulting in the increased fuel consumption and power deceleration is very rich. And except them there is a number of the uncharacteristic, but often found malfunctions, such as прогар piston, hit of fuel in oil, failure of one of sensors of temperature of system of injection, failure of the thermostat, pereputyvaniye of vacuum tubes, destruction of one of laying of the carburetor, piston rings or partitions of the piston. Diagnostics needs to be made without dismantling, otherwise the chance only for a while to eliminate the investigation or even to add the existing problem new, sometimes more difficult is high. For example, there is a lot of reasons leading to deceleration of power of a spark. If diagnostics is made on multipurpose the motor-testore, on its screen it is possible to define what shortcoming is available at once. In any other way it is impossible to estimate compliance of a form of iskroobrazovatelny process of that at which there is a full combustion of fuel on various operating modes. The situation when, having found signs of abnormal work in the engine, motorist goes to the mechanic is widespread. That, having measured a compression of the engine and having found compliance to norm, begins to adjust both the carburetor, and system of ignition, trying to obtain steady work. Sometimes it works well. The engine is regularly started, ceases to become deaf, but at the same time draft and fuel consumption leave much to be desired. In what a mistake? In the worn-out engine leakage of epiploons of valves often appears. The oil proceeding on pistons leads to artificial compensation of the gaps which arose at wear of pistons, rings and cylinders. And at measurement of a compression false testimonies turn out. Elimination of this malfunction after the "repair" made by the mechanic considerably is complicated because of need of restoration of initial adjustments. Also the reverse situation when the owner is unfairly "plunged" into capital repairs is very widespread though would be to replace the same epiploons enough, what is more than 10 times cheaper. Unfortunately, still in the market of servicing of cars approximately equal division into the stations meeting the modern requirements for qualification, technical and cultural service, and of splinters of sadly memorable Soviet car service remains. Therefore car owners should get acquainted with technical center on which hole they put the car attentively. And not so much with the cost of services, how many how than and in what conditions the car will be diagnosed and under repair. |
