Description
Technical field
The utility model relates to a kind of supercharging device, relates in particular to a kind of electronic and turbo double-intake supercharging device that is used for motor.
Background technique
Exhaust-gas turbocharger is the vitals that is used for improving engine power and reduces discharging, has been widely used in the motor industry.Exhaust-gas turbocharger utilizes the huge exhaust energy of motor to drive the turbine high speed rotating, to improve the engine air air inflow.Exhaust-gas turbocharger is installed on the engine exhaust pipe, and the High Temperature High Pressure waste gas that cylinder is discharged promotes turbine wheel and rotates, and drives the compressor impeller high speed rotating, will send into cylinder after the air pressurized of air-strainer.Increase because enter the air of cylinder, thus allow to spray into more fuel oil or fuel oil is burnt more fully, thus make transmitter produce bigger power or reduction discharging.Because turbosupercharger can be utilized exhaust energy, improve intake efficiency, obtain power back-off in the time of therefore motor being worked on the plateau, reduce the plateau power loss.But motor rotating speed when idling operation often has only hundreds of to change, and the engine exhaust energy shortage is to drive the turbine wheel high speed rotating, and turbosupercharger can not get involved work.General turbosupercharged engine does not all have the bypass valve of air inlet and exhaust, when idling operation, the inlet and outlet bypass valve is opened automatically, air inlet and exhaust are all without turbosupercharger, the working state of motor is equivalent to the motor of a natural aspiration at this moment, fresh air is directly to be inhaled into cylinder, and waste gas also is directly to enter in the atmosphere.
Under the altitude environment condition, because rarefaction of air, when especially altitude is greater than 4000m, oxygen content in the atmosphere only is 60% of Plain, and motor is in starting with when idle, and turbosupercharger can not be brought into play the effect of raising air inlet again, even adopt the motor of turbosupercharger still to have the problem of starting difficulty on the plateau, and motor only depends on the air quantity of natural aspiration under plateau and cryogenic conditions, causes to start the explosive force deficiency, also causes the engine cold-starting difficulty.
Summary of the invention
The purpose of this utility model has been to provide a kind of electronic and turbo double-intake supercharging device that is used for motor, and this device helps improving the motor adaptive capacity to environment, and effectively improves the startability of motor at cryogenic conditions.
The utility model is achieved like this, it comprises suction tude, air-strainer, electric booster, turbine air inlet bypass valve, turbosupercharger, air throttle, intake manifold, cylinder, the manifold of giving vent to anger, exhaust by-pass valve, baffler, outlet pipe, the air inlet bypass valve, the impeller that it is characterized in that turbosupercharger connects air throttle, by the suction tude air-strainer that is linked in sequence, electric booster, one end and the turbosupercharger of turbine air inlet bypass valve, the other end of turbine air inlet bypass valve is walked around turbosupercharger and is connected air throttle, air throttle connects intake manifold, intake manifold connects cylinder, cylinder connects an end of turbosupercharger and exhaust by-pass valve respectively by the manifold of giving vent to anger, the other end of exhaust by-pass valve is walked around turbosupercharger and is connected outlet pipe, turbosupercharger connects baffler by outlet pipe, the electric booster air inlet bypass valve that is connected in parallel.
Technique effect of the present utility model is: turbosupercharger can't provide compressed air during 1, having solved engine start and idling; 2, solve motor and under cryogenic conditions, started difficult problem.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is achieved like this, it comprises suction tude 1, air-strainer 2, electric booster 3, turbine air inlet bypass valve 4, turbosupercharger 5, air throttle 6, intake manifold 7, cylinder 8, the manifold 9 of giving vent to anger, exhaust by-pass valve 10, baffler 11, outlet pipe 12, air inlet bypass valve 13, the impeller that it is characterized in that turbosupercharger 5 connects air throttle 6, by suction tude 1 air-strainer 2 that is linked in sequence, electric booster 3, one end of turbine air inlet bypass valve 4 and turbosupercharger 5, the other end of turbine air inlet bypass valve 4 is walked around turbosupercharger 5 and is connected air throttle 6, air throttle 6 connects intake manifold 7, intake manifold 7 connects cylinder 8, cylinder 8 connects an end of turbosupercharger 5 and exhaust by-pass valve 10 respectively by the manifold 9 of giving vent to anger, the other end of exhaust by-pass valve 10 is walked around turbosupercharger 5 and is connected outlet pipe 12, turbosupercharger 5 connects bafflers 11 by outlet pipe 12, the electric booster 3 air inlet bypass valve 13 that is connected in parallel.
This electronic and working principle turbo double-intake supercharging system: when engine start, get by the electronic supercharging device of microcomputerized control, detect rotating speed by engine rotation speed sensor and be in idling mode, air inlet this moment bypass valve is in closed condition, the fresh air that comes through air-strainer carries out supercharging by electronic supercharging device, the air inlet bypass valve at turbosupercharger place is in open mode, walk around turbosupercharger through the pressurized air that electronic supercharging device is come, directly enter into intake manifold, make motor when starting, can obtain more sufficient air supply under the relative natural aspiration condition from the air inlet bypass valve.When altitude environment, make air input of engine by air can maintain an atmospheric pressure, when ensureing the plateau starting, can reach air inflow, thereby improve the starting performance of altitude environment at the following motor natural aspiration of height above sea level 1000m.The exhaust by-pass valve of turbosupercharger end is in open mode in the gas exhaust piping simultaneously.Waste gas is directly walked around turbosupercharger, and directly row is in atmosphere, and this moment, turbosupercharger was not passed through in the air inlet and the exhaust of motor.Especially under cryogenic conditions, motor turbine when idling operation own is to get involved work, can't offer corresponding air quantity, fresh air temperature on every side is low, after adopting electronic supercharging device, can be the pressurized air that motor provides capacity, fresh air is after compressing behind the electronic supercharging device, the relative surrounding environment of the temperature of combustion air improves a lot, and helps to improve the startability of motor under cryogenic conditions.
After the engine start success, change the rated speed operation over to, detect by speed probe this moment and be full speed, the air inlet bypass valve at electronic supercharging device place is in opening state, electronic supercharging device while dead electricity also shuts down, the air inlet bypass valve of turbosupercharger end is in closed condition, the exhaust by-pass valve of waste gas end is in closed condition, the waste gas that motor is discharged is as the turbine (in the outlet pipe way) of high speed motivational drive turbosupercharger, turbine drives coaxial impeller (in the admission line) compression fresh air again, send into cylinder again, because engine speed is a full-speed state, the waste gas velocity of discharge and secondary speed are also accelerated synchronously, and the air compression degree is just strengthened, the electronic relatively supercharging device of the air inflow of motor increases greatly, just can increase the output power of motor.
