Problems solved by technology

However, this design has its limitations. The camshaft mechanism with variable phase has a complex structure, difficult processing, and certain application restrictions.
Although the electromagnetic valve mechanism can continuously adjust the valve lift, using an electromagnet to counteract the valve spring to open the valve will require a large current, and when the distance increases, the electromagnetic force will weaken rapidly.
Due to the large size and heavy weight of commonly used valves, there are very strict requirements on the electromagnets in the electromagnetic valve mechanism, so the electromagnetic valve mechanism is difficult to apply to the field of diesel engines

Abstract

The invention relates to an engine auxiliary ventilation device, comprising an auxiliary valve (4), an auxiliary exhaust pipe (8), an electromagnetic valve mechanism (9), an auxiliary air channel (10), an auxiliary exhaust pipe electromagnetic valve (11), Intake pipe electromagnetic valve (12), control element (13) and auxiliary air intake pipe (14), it is characterized in that: auxiliary air duct (10) is connected to the inlet air channel (10) through auxiliary air intake pipe solenoid valve (12) through auxiliary air intake pipe (14) On the trachea (15); the auxiliary airway (10) is connected to the exhaust pipe (7) through the auxiliary exhaust pipe (8) through the auxiliary exhaust pipe electromagnetic valve (11); the electromagnetic valve mechanism (9), the auxiliary exhaust The pipe solenoid valve (11) and the auxiliary intake pipe solenoid valve (12) are controlled by the control element (13). The engine auxiliary ventilating device disclosed in the present invention not only increases the air intake flow area and exhaust flow area, improves the efficiency of the air exchange process, increases the intake charge, reduces the residual exhaust gas volume, increases the power of the engine, but also makes the engine Get good economy.

Description

technical field [0001] The invention belongs to the technical field of intake and exhaust of internal combustion engines, and in particular relates to an engine auxiliary ventilation device. Background technique [0002] The ventilation process of the internal combustion engine is the intake and exhaust process in which the internal combustion engine discharges the burned gas of this cycle and inhales fresh charge for the next cycle. It is the guarantee that the working cycle can be repeated continuously. For a four-stroke engine, the ventilation process is the entire process from the opening of the exhaust valve to the closing of the intake valve. The performance of the engine largely depends on its gas exchange process. In order to improve power and economy, it is often necessary to adopt measures and methods to reduce the loss of intake and exhaust flow and increase the charge coefficient. [0003] The requirements for the engine ventilation process change with the chang...
