Problems solved by technology
At present, the intake air preheating of the engine uses electric heating intake air. This method uses electric heating elements to heat the intake air, which consumes a lot of extra electric energy. The failure rate of electrical components and circuits is high in low temperature environments, and the reliability is not strong.

The invention discloses a reversible air inlet system and a method for preheating inlet air of an engine by using the same. The reversible air inlet system comprises a right air inlet pipe IV, a right air inlet pipe III, a right air filter, a right air filter sealing box, a right sealing box cover plate, a right air inlet box, a right air inlet pipe II, a right air inlet pipe cover plate, a right air inlet pipe I, a left air inlet pipe cover plate, a left air inlet pipe I, a left air inlet pipe IV, a left air inlet pipe III, a left air inlet box, a left air filter, a left air filter sealing box, a left sealing box cover plate and a left air inlet pipe II. The invention further discloses a method for preheating the inlet air of the engine by using the reversible air inlet system. By adopting the reversible air inlet system, preheating for the inlet air of engines in extremely-cold regions can be realized; the air inlet mode of the system is that air suction can be performed in an external environment or in an engine compartment; additional energy does not need to be consumed; working is stable and reliable; the working mode is flexible; the environment adaptivity is high; and the reversible air inlet system is especially applicable to operation requirement of engines in the extremely-cold regions.
Description
technical field [0001] The invention relates to a reversible air intake system, in particular to a reversible air intake system and a method for using it to preheat engine air intake. Background technique [0002] Central Russia has long winters and short summers. The ambient temperature span is large, the temperature range is -58~+40℃. At present, the engines are all electronically controlled engines, which have certain requirements on the intake air temperature. Therefore, the intake air of the engine needs to be preheated in the low temperature environment in winter, but it does not need to be preheated in summer. At present, the air intake preheating of the engine uses electric heating of the intake air. This method uses electric heating elements to heat the intake air, which consumes a lot of extra electric energy. The failure rate of electrical components and circuits is high in low temperature environments, and the reliability is not strong. Cooling water is also us...
