Problems solved by technology

[0002] As people's demand for engine power and emission regulations become more and more stringent, supercharging technology has been widely used in diesel engines and even gasoline engines. The exhaust itself or the speed itself is controlled, and the reliability and real-time performance are not good
Due to the research and development of HCCI technology, the precise control of various elements of engine combustion has attracted the attention of various engine research and development units. The current supercharging technology has the disadvantage of not being able to accurately control the adjustment and control of the intake pressure. Due to the existence of these shortcomings, the engine cannot accurately control the combustion.

Abstract

The invention relates to a diesel motor air inlet pressurizing device, in particular to an engine air inlet pressure accumulation and control device. The invention is characterized in that an inlet of an air inlet manifold of the engine is orderly provided with an air pump, a one-way valve and a pressure accumulation barrel along the air inlet direction, an electromagnetic valve which is controlled by the ECU is connected between the pressure accumulation barrel and the air inlet manifold which are provided with a pressure sensor respectively under the control of the ECU, the air inlet manifold is also provided with an air inlet flow meter under the control of the ECU; the ECU controls the opening and the closing of the electromagnetic valve by the pressure sensor and the air inlet flow meter. The invention controls the air intake pressure by controlling the electromagnetic valve through the ECU and further controls the air input of the air inlet manifold of the engine, thereby realizing the accurate control of the air intake of the engine and further the accurate control of the combustion.
