How can economical driving be the cause of a capital repair car?

Many motorists are confident that during the trip, using low engine speeds and, accordingly, slowly moving along the road, you can reduce fuel consumption. However, frequent driving in this mode can cause a rapid deterioration of the motor and, as a result, a rapid approach to overhaul.

Consequences of slow driving

Driving at low revs affects the poor supply of oil to engine parts, which leads to «oil starvation». Why is this happening?

The situation is as follows. Pumping oil is engaged in an oil pump, it directly connected to the crankshaft. In addition, during each turn, it pumps a certain amount of oil. The connection with the crankshaft complicates the work process, since the amount of crankshaft rotation now depends on the oil volume.

In addition, it is important what state of the car.

• If you have a new car, and you care for it well, then, with a high probability, the oil channels are clean.
• In the event that the mileage of the vehicle is more than 150,000 km and the «low speed» mode is used, there may be a problem with the lack of lubrication.

In addition, even if there is an oil pressure sensor, which, of course, is on every car, it will be difficult to determine the «oil starvation», because it shows the lack of oil, and its insufficient supply. Therefore, in this case, the light will not flash.

What is really happening?

Therefore, it already known that the oil pump directly connected to the crankshaft of the engine. Therefore, the oil flow rates at 1,500 rpm and at 3,000 rpm will be significantly different. As a result, all engine systems suffer:

• Lubrication of engine parts will be inadequate.
• Heat from elements that are heated cannot properly discharged.

Over time, this can lead to suspicious noise, engine overheating or even a vehicle failure.

Suddenly accelerate – the consequences for the car

Everyone had to at least sometimes, during the trip, not even very long, to accelerate sharply. This happens in many motorists regularly – this requires traffic or driving style. Sometimes the driver just wants to try out his car for stamina.

In each of these cases, during such acceleration, the control unit sends a signal to supply the cylinders with the fuel-air mixture in a larger quantity than required. As a result, the pump and oil pump cannot cope with such pressure and not immediately accelerated in operation.

In addition, the cylinders have already accumulated heat, significantly exceeding the allowable rate. Moreover, since there is nowhere to go, it creates a significant burden on the group of pistons and the block itself. Detonation can also occur, it will have adverse consequences and, as a result, major repairs.

The result will expected. Wanting to save, you put the engine and all systems overloaded. In this case, the transmission is also subject to wear.

Draw conclusions

Still, you need to regularly remember the tachometer and watch its arrow so it's near the mark – although it's worth remembering that these extremes can also cause premature access to the service. In the case of a long stay in traffic jams, it on the second part of the road greatly accelerate traffic. This will help restore the balance and normalize the lack of oil supplied to the engine.
