The popular belief that fuel injected engines don't need to warm up, is quite wrong. All you need to know the measure. If you start driving on a cold motor, you 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. Thus it is necessary to pay attention to the smooth working of the engine. The turnovers should be minimal and stable. If not, adjust the idle speed. In no case do not press "gas", otherwise, they'll have to do a complete engine overhaul. In the process at lower temperatures as carbureted and fuel-injected engine that dramatically increases the wear of piston group parts. This happens due to poor fuel evaporation. Also accelerated corrosion. In turn, this is because the coolant temperature is below 60 degrees Celsius. This leads to the formation of condensate. Water vapor and sulfurous gases contained in the combustion products, lead to the formation of the electrolytic film. Condensation also gets in the oil, leading to the formation of sticky deposits, clogging the channels and oil filters.Negative temperature running fuel injected engine and reduces its power. This happens due to the incomplete combustion of gasoline. Increases the viscosity of the oil, resulting in increasing the cost of the net power going to overcome the forces of friction of pistons. All of these factors are directly linked to the quality of lubrication. If you want your engine worked for as long as possible, it is better not to save.For injection engine fits best synthetic oil. It has a rather high fluidity and penetrating power. These features allow you to peel off the deposits formed on the internal surfaces of the engine. Unfortunately, mineral oil does not have the same ability. If the injection engine system of correction of the fuel-air mixture is healthy and flooded with synthetic oil, letting the engine idle may take only a few seconds in summer and two minutes in winter. The engine needs to warm up only to operating temperature, and waiting until you warm up the oxygen sensor and will be back to normal the oil pressure in the system.
