Description
Technical field
The utility model relates to a kind of motor polishing device, particularly relates to a kind of making-up air device of applicable large diesel engine state of starting operating, belongs to automobile technical field.
Background technique
Turbocharging technology enhances working process of diesel engine, improves the power per liter of diesel engine, and supercharging technology improves the charging efficiency of diesel engine, is conducive to improving the diesel engine thermal efficiency, improves fuel economy.
But, when common exhaust turbosupercharger is applied on large diesel engine, the phenomenon of ubiquity pressurized machine response lag, particularly heavy-duty diesel oil automobile.During vehicle launch, when driver steps on the throttle pedal, fuel delivery increases sharply, but now the gas of combustion energy of diesel engine is also not enough to drive pressurized machine work, air inflow is caused not mated with fuel delivery, occur the situation that oily many gas is few, the carbon smoke exhaust of diesel engine increases, and easily occurs the phenomenon of " over-emitting black exhaust ".
Model utility content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of making-up air device of applicable large diesel engine state of starting operating, the problem of air pressure deficiency " over-emitting black exhaust " during solution diesel engine starting.
The technical solution of the utility model is such: the making-up air device being applicable to large diesel engine state of starting operating, comprise gas compressor, ECU (Electrical Control Unit) and magnetic switch, described blower outlet is connected with air inlet path for diesel engine, described ECU (Electrical Control Unit) is connected with throttle position switch, air inlet pressure sensor and turbo charger speed sensor, described magnetic switch is controlled by ECU (Electrical Control Unit), and the suction pressure recorded when air inlet pressure sensor is less than setting value, it is that non-idle and turbo charger speed sensor record turbo charger speed when being less than rated speed that throttle position switch records diesel engine, magnetic switch is opened and is controlled gas compressor work.
Further, described gas compressor is driven by motor, described magnetic switch access motor power loop.
Further, described motor is connected with vehicle battery, the loop of described magnetic switch access motor and vehicle battery.
Further, during described gas compressor work, air inlet path for diesel engine air pressure is 0.2 ~ 0.3MPa.
The advantage of technological scheme provided by the utility model is, realize the state of starting operating at large diesel engine, magnetic switch is controlled by ECU (Electrical Control Unit), indirect control driven by motor centrifugal-flow compressor is to intake duct conveying high-pressure air, increase air inflow during diesel engine starting, regulate oil-gas ratin when starting, improve burning degree of perfection, reduce carbon smoke exhaust.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Refer to Fig. 1, the making-up air device of the applicable large diesel engine state of starting operating involved by the utility model, high-speed electric expreess locomotive 9, electric centrifugal-type gas compressor 1, ECU (Electrical Control Unit) 2, throttle position switch 6, air inlet pressure sensor 7, turbo charger speed sensor 8 and each connection pipe fitting composition.High-speed electric expreess locomotive 9 is powered by vehicle battery 10, and high-speed electric expreess locomotive 9 and electric centrifugal-type gas compressor 1 are by spline joint, and electric centrifugal-type gas compressor 1 is connected with diesel engine 4 intake duct 5 by pipeline.The power loop of this device between high-speed electric expreess locomotive 9 and vehicle battery 10 is provided with magnetic switch 3, diesel engine 4 intake duct 5 place is provided with air inlet pressure sensor 7, turbosupercharger place is provided with turbo charger speed sensor 8, and gas pedal place is provided with throttle position switch 6.ECU (Electrical Control Unit) 2 is electrically connected with the sensor and receives respective sensor signals, controls magnetic switch 3 break-make, indirectly controls electric centrifugal-type gas compressor 1 and works.ECU (Electrical Control Unit) 2 receives air inlet pressure sensor 7 signal, compares with setting suction pressure; Receive throttle position switch 6 signal, determine throttle initial position and calculation of throttle position rate; Receive turbo charger speed sensor 8 signal, compare with turbosupercharger rated speed.When diesel engine 4 initial start stage, suction pressure is less than setting suction pressure, and driver steps on the gas deeply, accelerator pedal position forward accelerates change and regards as non-idle, turbosupercharger not yet gets involved, and during rotating speed light rain rated speed, ECU (Electrical Control Unit) 2 sends magnetic switch 3 open command, high-speed electric expreess locomotive 9 and vehicle battery 10 are connected and are driven electric centrifugal gas compressor 1 control air to be transported to intake duct 5 after compression, increase air inflow; After entering nominal situation, turbo charger speed is normal, and ECU (Electrical Control Unit) 2 cuts off magnetic switch 3, and electric centrifugal gas compressor 1 just no longer carries out tonifying Qi.
