The causes of the problems with the launch of a warm engine
The problem with the launch of a warm engine is not only true for older cars with significant mileage, but also for newer cars with modern construction. What could be the causes of such problems?
The list of potential errors that can cause problems with the launch of a warm engine is unfortunately long. And their disposal corrections contributes to the accelerated consumption of a number of other components.
Do you have problems with the launch of a warm engine? The cause may be a malfunction of the valve
One of the most common causes of problems with “burning” hot units is its natural wear and lack the necessary adjustments are made according to the manufacturer's instructions. This is especially true for vehicles with considerable mileage. In any internal combustion engine, after a time, components can degrade.
Especially in cars with gas-powered or CNG, alone valve seats and valve wear faster.
In most cases, the problem is solved by a hydraulic control valve. If this is not the case, every few tens of thousands of kilometers should tell the mechanic to manually prešteluje valves – lack of such regulation will discover, among other things, problem starting the warm engine. Partially open valves caused great loss of compression, which leads to significant problems with the launch of the drive unit, while during the ride comes to a clear decline of power and increased fuel consumption.
The problem of labor hot diesel engine is often caused by a lack of fuel in highway, cause
Many owners of cars with modern diesel engines are struggling with the problem of starting a warm engine.
The cause in this case may be a lack of fuel supply, magistrali, more precisely insufficient pressure in the fuel system. Minor leaks in the fuel system diesel unit with common-rail direct injection caused the return of diesel fuel in the fuel tank “after shutdown” engine. As a result,, try restarting requires more cranking (start) engine. Only then will the fuel pump make the appropriate pressure in the system.
Diesel fuel in fully functional correct the engine should remain in Highway , High pressure – Only in these conditions injectors are able to create appropriate conditions for ignition in the combustion chambers.
This problem mainly refers to units without electric fuel pump, which is located in the tank (1.6 HDI PSA or 1.6 CRDI group installed in Hyundai and Kia).
It should look for the leaks in the high pressure pump, or the wear of the valve controlling the operation of a common rail injector – the latter is seen assay spill.
Membrane and the seals in the pump working under high pressure under the influence of low-grade diesel fuel are subject to rapid degradation. Impurities and high content of undesirable substances contribute to hardening and curing rubber seals, which leads to loss of strength.
Startup problems can be problems with Ansserom
Standard cause problems when starting the drive unit is … starter. Remember that this element is also subject to wear and tear – After years of not generating the required engine speed for a smooth start. Here defect solved by replacement or overhaul of the subassembly.
You have a problem with the engine, check valve train (zupšasti trouser belt or chain)
Proper functioning of the timing engine has a huge impact on the smooth starting of the engine. Thanks to this mechanism (realized by means of the belt or chain), the valve timing control.
The problem arises especially in modern engines equipped with chain as divorce – lower the quality of the materials used and a large load drive unit results in faster wear subassembly. The chain is towed, resulting in deregulated Timing. This problem will be solved only by replacing the entire chain of divorce.
The problem often occurs in the first VAG 1.4 TSI engines, as well as in 1.6 THP-in that made engineers Bmw-and the PSA group.
Changing the chain will not be cheap. Advanced mechanisms using gears, Set tensioner and rollers require a lot of time for servicing, and often the dismantling of several elements in order to obtain access to the switch mechanism.
Want to avoid trouble, remember the manufacturer's recommendations
Regardless of the age and the technical sophistication of the car, regular service is of great importance. In accordance with the manufacturer's, Operating as a substitute and regulations are the key to safe and efficient use for many years.
Seemingly small issues, can cause problems described when starting a warm engine. Unfortunately, in the case of modern engines, you must consider the high costs of replacement or repair of the components, especially in the case of common rail injector, that can not be repaired.
