Abstract
The utility model relates to a novel intake system of electronic injection gasoline engine provided with an electric booster pump. The intake system comprises an air filter, a cylinder and a ternary catalytic reactor. The air filter and the cylinder are connected with an admission pipe, and the cylinder and the ternary catalytic reactor are connected with the admission pipe too. The utility model is characterized in that: the admission pipe between the air filter and the cylinder is provided with the electric booster pump. The exhaust gas turbocharger drove by the exhaust gas discharged by the engine and the mechanical booster pump drove by the power of the engine are instead by the electric booster pump, which greatly decreases the loss of the engine power and reduces the production cost.
Description
Technical field
The utility model relates to a kind of EFI petrol engine, especially relates to a kind of petrolic gas handling system of novel EFI that has electric booster pump.
Background technique
At present, the employing Variable Valve Time that has of the petrol engine of more advanced car and changeable air valve stroke all are that the air inflow that increases cylinder improves engine power.But the shortcoming of this way is that cost is higher, the manufacturing process complexity.For the air inflow that increases cylinder improves the power of motor, save fuel oil to reach, reduce the purpose of polluting, exhaust-gas turbocharger or mechanical booster pump generally are housed in the gas handling system of domestic and international medium-to-high grade motorcar engine.But, exhaust-gas turbocharger is to drive by the waste gas that motor is discharged, mechanical booster pump leans on the power of motor to drive, these two kinds of designs all can the loss motor power, though these two kinds of designs have raising to the total power of motor, but, bigger to the loss of engine power, and manufacture cost is higher.
The model utility content
The utility model mainly is that solution existing in prior technology exhaust-gas turbocharger or mechanical booster pump are bigger to the power loss of motor, the technical problem that manufacture cost is more high, provide on a kind of admission line between air-strainer and cylinder electronic centrifugal supercharger has been set, the less and petrolic gas handling system of lower-cost novel EFI the power loss of motor.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the petrolic gas handling system of a kind of novel EFI, include air-strainer, cylinder, three-way catalytic converter, all connect by admission line between air-strainer and the cylinder and between cylinder and the three-way catalytic converter, it is characterized in that: the admission line between described air-strainer and the cylinder is provided with electric booster pump.The mechanical booster pump that exhaust-gas turbocharger that original waste gas of discharging by motor is driven or the power that relies on motor drive changes electric booster pump into, has significantly reduced the loss to engine power, has also reduced cost of production simultaneously.
As preferably, described electric booster pump includes centrifugal supercharger and motor.Electric booster pump is made of centrifugal supercharger and motor, centrifugal supercharger air to inspiration under the driving of motor compresses, increase the air inflow of cylinder, motor links to each other with the storage battery of motor and motor, and is less to the loss of generator power.
As preferably, described centrifugal supercharger includes housing, and described motor is fixed on the housing, and motor is provided with rotatingshaft, and described rotatingshaft extend in the housing, and the rotatingshaft in the described housing is provided with impeller.
As preferably, the voltage rating of described motor is 12V.The voltage rating of motor is 12V, and the rated power of motor is less, and is also less to the loss of generator power.
Therefore, the utlity model has following characteristics: 1. simple in structure, reasonable in design; 2. by on the admission line between air-strainer and the cylinder, electric booster pump being set, significantly reduced loss, also reduced cost of production engine power; 3. owing to the loss that has reduced engine power, saved fuel oil, reduced pollution environment.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is that the A of centrifugal supercharger of the present utility model is to view.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: the petrolic gas handling system of a kind of novel EFI, include air-strainer 1, cylinder 2, three-way catalytic converter 3, all connect by admission line 4 between air-strainer 1 and the cylinder 2 and between cylinder 2 and the three-way catalytic converter 3, the admission line 4 between air-strainer 1 and the cylinder 2 is provided with electric booster pump 5 (referring to accompanying drawing 1).The mechanical booster pump that exhaust-gas turbocharger that original waste gas of discharging by motor is driven or the power that relies on motor drive changes electric booster pump 5 into, has significantly reduced the loss to engine power, has also reduced cost of production simultaneously.Electric booster pump 5 includes centrifugal supercharger 6 and motor 7, and the voltage rating of motor 7 is 12V.Centrifugal supercharger 6 air to inspiration under the driving of motor 7 compresses, and has increased the air inflow of cylinder 2, and motor 7 links to each other with the storage battery of motor and motor, and is less to the loss of generator power.Centrifugal supercharger 6 includes housing 8, and motor 7 is fixed on the housing 8, and motor 7 is provided with rotatingshaft 9, and rotatingshaft 9 extend in the housing 8, and the rotatingshaft 9 in the housing 8 is provided with impeller 10.
