Some car lovers encountered engine tempering blasting, especially in some older model vehicle age, the more obvious in autumn and winter cold weather. You know what is going on riders do not think there is a car there is some fault, but I do not know the new owner thought his car had major problems.
In fact, car ldquo; blasting rdquo; phenomenon can be understood as a simple: it should have been mixed gas combustion and explosion in the engine cylinder, but it was only at the exhaust pipe to the ignition, high temperature exhaust gas containing the combustible gas into the large after the exhaust pipe, the combustion fresh air again encountered, the exhaust pipe is formed ldquo; blasting rdquo ;. Do not underestimate the power of much more serious than the fireworks exploded. So if this phenomenon occurs, the owner is necessary and timely attention. There are reasons
for this phenomenon are many, there are six common reasons:
1, the mixture is too lean: automobile engine backfires blasting failure may be oil or air intake system failure: failure is mainly due to the oil injector fuel injection due to too little, the cause of too little fuel injector fuel injection are: oil press low; injector clogging. Intake system failure is mainly due to excessive intake air amount due, the cause of excessive intake air amount mainly: the control of the intake air amount sensor failure; intake manifold leak.
2, ignition system problems: insufficient ignition energy (high-voltage resistance is too large; ignition coil; supply voltage is not enough), ignition sequence disorder, should jump ignition fire, the ignition time no flashover, spark plug or ignition delay faults;
3, valve problems: insufficient degree of sealing of the valve, open enough, insufficient combustion of gasoline , the exhaust gas can not be discharged to excess;
4, gasoline problems: the addition of inappropriate or impure gas;
5, operational problems: too high throttle added, in a very at high speed, the engine occurs when the normal shooting. It may be a low-speed operation usually have been shoved a high-speed engine stand.
6, carbon deposits inside the engine too serious.
launchedMachine ldquo; blasting rdquo; it sounds cool, look cool, but in fact a lot of trouble. This phenomenon is at least shows the engine oil, air intake system or the ignition system is faulty. If left untreated, over time lead to other failures to overhaul trouble. Note that the mixed gas outside the explosive combustion in the engine, much more powerful than the power of fireworks, comparable to a small oil and gas bombs, severe damage to the exhaust system directly. So when there is this phenomenon, the owner should timely manner.
