conventional wisdom that fuel injected engines do not need to warm up, very wrong.In all you need to know the measure.If you start moving when engine is cold, it can quickly ruin the cylinder-piston system.Therefore, in the cold season it is recommended to warm up the engine for at least 1-2 minutes.It is worth paying attention to the smooth running of the engine.Turnover should be minimal and stable.If not, adjust the idle speed.In no case do not press the "gas to the floor", otherwise then have to do a major overhaul of the engine.In operation, at lower temperatures, as the carburettor and injector motor abruptly increases wear piston.This occurs due to the poor evaporation of the f
uel.Also, accelerated corrosion wear.In turn, this is because the coolant temperature is below 60 degrees Celsius.This leads to the formation of condensate.Water vapor and sulfur dioxide gases, which are contained in the combustion products, leading to the formation of the electrolytic film.The condensate also falls in the oil, leading to the formation of sticky deposits clogging the channels and oil filtry.Otritsatelnaya injection engine operating temperature and reduce its capacity.This happens due to incomplete combustion of gasoline.Viscosity increases, thereby increasing the cost of the net power going to overcome the friction forces of the pistons.These factors are directly related to lubricant quality.If you want your engine worked for as long as possible, then it is better not to ekonomit.Dlya injection engine best synthetic oil.It has a fairly high turnover and penetrating ability.These characteristics allow flaky deposits formed on the inner surfaces of the engine.Unfortunately, the mineral oil do not have the same capacity.If the fuel-injected engine system correcting the fuel-air mixture is working and filled synthetic oil, then warm up the engine idling may take only a few seconds in the summer and up to two minutes in winter.The motor should be just warm up to operating temperature, waiting until the oxygen sensor heats up and returns to normal oil pressure in the system.
