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.


Suitable building for garage

Own car repair shop is the biggest dream of many mechanics. But before we start to run their own business, conical is to find a suitable location, and - a building that will provide comfortable working conditions. Ideally, you will find in it both the canal and on the lift. In addition, we find such an object, which will include space for storage of spare parts, and of course the social room. You should also remember the special containers for screws and plates on the wall where suspend wrenches and other tools - this will facilitate the maintenance of order. A good solution is a building next to which there is a place for parking cars repaired.


This oil film

In the crankcase of a vehicle engine, motor oil lubricates rotating or sliding surfaces between the crankshaft journal bearings (main bearings and big-end bearings), and rods connecting the pistons to the crankshaft. The oil collects in an oil pan, or sump, at the bottom of the crankcase. In some small engines such as lawn mower engines, dippers on the bottoms of connecting rods dip into the oil at the bottom and splash it around the crankcase as needed to lubricate parts inside. In modern vehicle engines, the oil pump takes oil from the oil pan and sends it through the oil filter into oil galleries, from which the oil lubricates the main bearings holding the crankshaft up at the main journals and camshaft bearings operating the valves. In typical modern vehicles, oil pressure-fed from the oil galleries to the main bearings enters holes in the main journals of the crankshaft. From these holes in the main journals, the oil moves through passageways inside the crankshaft to exit holes in the rod journals to lubricate the rod bearings and connecting rods. Some simpler designs relied on these rapidly moving parts to splash and lubricate the contacting surfaces between the piston rings and interior surfaces of the cylinders. However, in modern designs, there are also passageways through the rods which carry oil from the rod bearings to the rod-piston connections and lubricate the contacting surfaces between the piston rings and interior surfaces of the cylinders. This oil film also serves as a seal between the piston rings and cylinder walls to separate the combustion chamber in the cylinder head from the crankcase. The oil then drips back down into the oil pan.45

Motor oil may also serve as a cooling agent. In some constructions oil is sprayed through a nozzle inside the crankcase onto the piston to provide cooling of specific parts that undergo high temperature strain. On the other hand, the thermal capacity of the oil pool has to be filled, i.e. the oil has to reach its designed temperature range before it can protect the engine under high load. This typically takes longer than heating the main cooling agent ? water or mixtures thereof ? up to its operating temperature. In order to inform the driver about the oil temperature, some older and most high performance or racing engines feature an oil thermometer.

Due to its high viscosity, motor oil is not always the preferred oil for certain applications. Some applications make use of lighter products such as WD-40, when a lighter oil is desired, or honing oil if the desired viscosity needs to be mid-range.6
