Jeep smoking exhaust Why do not you take to repair the car?
Often our cars are accidents and then it is necessary to repair. Many of us are doing it on their own, however, such a solution for many reasons may not be a bad idea. Why is it like that? When we repair all by yourself, we can never be sure that we can deal with failure. We can not be confident that the repair will be successful, and if you're stuck at a standstill, the situation may cause us many problems. Good workshops give us confidence that the car will be repaired, and often a guarantee that will work for a long time, and when it breaks down, however, parts will be replaced at the expense of the mechanical plant. It is much safer solution.
Cheating in repairing
The best solution when it comes to servicing cars of choice is a trustworthy mechanic. It is not always possible, however, and often urgent need to repair our car brings us to the first workshop better. Therefore, the maintenance of cars is often very complicated process, and a relatively small portion of the users of cars are aware of this, as should proceed car repair easily become a victim of fraud. We can never be sure yet how much of the car has been mentioned, if you do not have enough knowledge on this topic. Therefore it is worth before going to the workshop to do some research on this type of service, for example, among family and friends.
Positive Crankcase Ventilation
Motor oil is a lubricant used in internal combustion engines, which power cars, motorcycles, lawnmowers, engine-generators, and many other machines. In engines, there are parts which move against each other, and the friction wastes otherwise useful power by converting the kinetic energy to heat. It also wears away those parts, which could lead to lower efficiency and degradation of the engine. This increases fuel consumption, decreases power output, and can lead to engine failure.
Lubricating oil creates a separating film between surfaces of adjacent moving parts to minimize direct contact between them, decreasing heat caused by friction and reducing wear, thus protecting the engine. In use, motor oil transfers heat through convection as it flows through the engine by means of air flow over the surface of the oil pan, an oil cooler and through the buildup of oil gases evacuated by the Positive Crankcase Ventilation (PCV) system.
In petrol (gasoline) engines, the top piston ring can expose the motor oil to temperatures of 160 °C (320 °F). In diesel engines the top ring can expose the oil to temperatures over 315 °C (600 °F). Motor oils with higher viscosity indices thin less at these higher temperatures.
Coating metal parts with oil also keeps them from being exposed to oxygen, inhibiting oxidation at elevated operating temperatures preventing rust or corrosion. Corrosion inhibitors may also be added to the motor oil. Many motor oils also have detergents and dispersants added to help keep the engine clean and minimize oil sludge build-up. The oil is able to trap soot from combustion in itself, rather than leaving it deposited on the internal surfaces. It is a combination of this, and some singeing that turns used oil black after some running.
Rubbing of metal engine parts inevitably produces some microscopic metallic particles from the wearing of the surfaces. Such particles could circulate in the oil and grind against moving parts, causing wear. Because particles accumulate in the oil, it is typically circulated through an oil filter to remove harmful particles. An oil pump, a vane or gear pump powered by the engine, pumps the oil throughout the engine, including the oil filter. Oil filters can be a full flow or bypass type.
