Many car enthusiasts believe that fuel economy is achieved by driving at low speeds. However, this approach to driving can come with hidden costs. In an interview for the njcar.ru portal, an engine repair expert explained why driving at low speed is dangerous for an internal combustion engine.
In cities with frequent traffic jams, it is difficult to maintain high speeds, and the engine works at its limit most of the time. However, in urban environments, sudden acceleration is sometimes required. In such cases, when the operating mode changes suddenly, the cylinders are filled with a rich fuel mixture, which may cause an explosion.
Modern engines adapt to these conditions by changing the operation of the ignition system, but the fuel does not burn completely, leading to carbon deposits and clogged injectors.
It can cause significant damage not only to the engine, but also to key components such as bearings, transmissions and clutches, with pistons and crankshaft bearings usually being the first to fail.
In addition, the speed of the engine directly affects the oil pump pressure. At low speeds, this pressure drops, which reduces the lubrication efficiency of internal engine parts and accelerates engine wear.
Therefore, regular use of low speeds will adversely affect engine performance. The best performance of a naturally aspirated petrol engine is achieved between 2500 and 3500 rpm, so it is recommended to keep the tachometer at this level for best performance and extended engine life.
