Embodiment
As shown in Figure 1, the utility model boosting compensation device of engine, comprise air cylinder 1, solenoid valve 2 and air inlet brake assemblies, the air inlet brake assemblies is connected with the suction valve of motor, the opening and closing of control suction valve, air cylinder 1 is external in the intake manifold 3 of motor, and solenoid valve 3 is located between air cylinder 1 and the intake manifold 3, and solenoid valve 2 is controlled its open degree by the electromagnetic valve assembly.One end of intake manifold 3 connects empty filter 6.
As shown in Figure 2, the electromagnetic valve assembly comprises intake air temperature sensor 7, air inlet pressure sensor 8 and control unit of engine ECU, intake air temperature sensor 7, air inlet pressure sensor 8 is installed in the intake manifold 3, intake air temperature sensor 7 and air inlet pressure sensor 8 pass to control unit of engine ECU with the signal of collecting, control unit of engine ECU received signal and treatment conversion are data-signal, and then with control unit of engine ECU in initialize data contrast after, produce control signal, and this control signal fed back to solenoid valve 2, control signal can control electromagnetic valve 2 open degree, thereby the air supply that enters cylinder.
Solenoid valve 2 is to adopt pulse width modulation solenoid valve PWM (Pulse Width Modulation) control, can quantitatively control air by accounting for wide ratio and pulsewidth.In intake manifold 3, be provided with one-way valve 4, avoid gas to flow backwards.Air cylinder 1 is used for storing pressurized air.
The operating mode different according to motor, obtain intake temperature and pressure parameter by intake air temperature sensor (the MAT)/air inlet pressure sensor (MAP) that is installed in intake manifold, with the rotation speed n under this operating mode of motor, load load signal is delivered to control unit of engine (ECU) together, ECU can be with parameter under this operating mode and the good map spectrum data comparative analysis of demarcation in advance then, thereby calculate the air quantity that needs actual compensation to enter cylinder, thereby the aperture of solenoid valve is accurately controlled air inflow in the control air cylinder, guarantee optimum air-fuel ratio, improve combustion efficiency, and increase engine power.This means that a size motor identical with weight can produce more power after air intake pressurized, a small displacement engine can produce after supercharging and the big identical power of motor in other words, and saves advantages such as fuel oil and reduction discharging in addition.
As shown in Figure 3, the air inlet brake assemblies comprises housing 14, on housing 14, driven plunger assembly 17 is installed by adjusting screw 12 and nut 13, on driven plunger assembly 17, be provided with draining pin 16, above draining pin 16, be provided with ring washer 15, in driven plunger assembly 17, be provided with filter screen folder 20 and filter screen 21, be connected with spring sheet 18 and bolt 19 at driven plunger assembly 17, by pressing plate 27 and bolt 28 solenoid valve 26 is installed at housing 14, on the surface of contact of solenoid valve 26 and housing 14, be provided with O RunddichtringO 22,23,24, be used for enhanced leaktightness.Also be provided with filter screen 25 at solenoid valve 26.
