Abstract
The invention discloses a vacuum driving system and a motorcycle thereof. The vacuum driving system comprises a vacuum tank, and the vacuum tank is communicated with an intake manifold of an engine through an air outlet one-way valve. By using the structures of the vacuum tank and the one-way valve, the vacuum degree of the intake manifold is stably stored to form the driving system for driving by using stable negative pressure, and the stability of the vacuum degree is ensured under the action of the one-way valve; when a certain parameter of the engine needs to be matched with the air inlet quantity of the engine, the change is driven by the driving system, and the driving system can drive stably so as to avoid lag; for example, when the rotational speed of the engine reaches a set value, the negative pressure drive starts driving related equipment, and the driving force is increased together with the increment of the rotational speed; and when the rotational speed is lower than the set value, the negative pressure drive is closed and reset so as to ensure that the related parameters of the engine can be matched with the air inlet quantity in high, medium and low-speed rotation.
Description
Technical field
The present invention relates to a kind of motorcycle part and car load, particularly a kind of motorcycle engine gas handling system and motorcycle thereof.
Background technique
Motorcycle has stronger road worthiness because light and flexible is travelled rapidly, obtains using comparatively widely.
Motorcycle engine is by suction feed mixed gas to be sucked the firing chamber to burn, and therefore, for air intake pipe, inside has certain degree of vacuum, and this degree of vacuum is the main control parameters that decision enters air quantity; But this degree of vacuum is the operation frequency along with motorcycle engine is periodically variable, for admission line and other external parameters relevant with engine speed, can not change along with the variation of this degree of vacuum flexibly; Such as, the variation of air inflow can not be followed the variation of degree of vacuum and be changed, and causes certain air inlet error, also just can not form the air fuel ratio that adapts to engine operating condition, air fuel ratio is the index of outbalance, has determined the running condition of vehicle and whether has discharged compliance with environmental protection requirements.During the motor operation, the air inlet amount is self-regulating according to the engine speed height, because engine air inlet tube is certain, though increase along with engine speed, air inflow can not increase in proportion, air fuel ratio can not reach combustion requirements, so the motor operation conditions is worsened, the inadequate situation of burning occurs; And if pay attention to air inflow simply, then can make motor lower in low-speed running efficient, cause car load to be difficult to start, discharging is not up to standard and be short of power.Certainly, during the motor operation, also have a lot of other economic and technical norms relevant with intake manifold vacuum, all can not realize synchronous coupling, the state of its operation directly influences the running state and the economic indicator of car load.
Therefore, need a kind of device that can stablize engine intake manifold degree of vacuum, vacustat in the intake manifold can be exported, being used to drive the matching unit relevant with this degree of vacuum avoids occurring lagging behind, guarantee the rational Match of the every economic and technical norms of motor, thereby improve the operational efficiency and the service behaviour of motor.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of vacuum driven system and motorcycle thereof, vacustat in the intake manifold can be exported, being used to drive the matching unit relevant with this degree of vacuum avoids occurring lagging behind, guarantee the rational Match of the every economic and technical norms of motor, thereby improve the operational efficiency and the service behaviour of motor.
Vacuum driven of the present invention system comprises that the described vacuum tank of vacuum tank is communicated in engine intake manifold by an outgassing nonreturn valve.
Further, also comprise the negative pressure driver that is used for the output of the vacuum power in the vacuum tank, described vacuum tank is communicated in the negative pressure driver,, simple in structure by the negative pressure driver with the output of vacuum power, reliable in action, and have certain effect of releiving, guarantee the slow variation of engine operating condition.
Further, comprise that also negative pressure drives automatic control system, described negative pressure drives automatic control system and comprises solenoid valve and engine rotation speed sensor, vacuum tank is communicated in the negative pressure driver by solenoid valve, engine rotation speed sensor detection of engine revolution signal transfers to motorcycle ECU, ECU according to engine rotational speed signal to the electromagnetic valve signal of partly giving an order; According to the rotary speed parameter of motor, open or close the driving of vacuum for the negative pressure driver, be beneficial to the coupling that can guarantee driven equipment and motor operation conditions; Be specially adapted to control, can guarantee more suitable air fuel ratio, improve the performance of motor gas handling system; Rotating speed reaches setting value, and solenoid valve is opened, and the negative pressure driver is opened under the effect of vacuum tank, when rotating speed is lower than setting value, and closed electromagnetic valve, the negative pressure driver resets.
Further, described negative pressure driver be provided with can be under negative pressure drives reciprocating negative pressure driveshaft, in driving the miscellaneous equipment process, have the linear motion rule, can be applicable to the engine speed that gradually changes, reach preferable matching status.
Further, described negative pressure driver is provided with the rotating drive end that negative pressure drives; Drive corresponding apparatus by rotating output, can dismiss set goal of the invention.
The invention also discloses a kind of motorcycle of using the vacuum driven system.
The invention has the beneficial effects as follows: vacuum driven system of the present invention and motorcycle thereof, utilize vacuum tank and one-way valve structures, the vacustat of intake manifold is stored, constitute to utilize and stablize the drive system that negative pressure drives, and under the effect of one-way valve, guarantee the stable of degree of vacuum, when a certain parameter of motor was need be with engine charge flux matched, then it changed by drive systems, can be stable drive avoids occurring retardation phenomenon; For example, when reaching rotating speed, motor reaches setting value, and can be in conjunction with other parameter acquisition equipment, negative pressure is driven begin to drive relevant device, when rotating speed is lower than setting value, negative pressure drives to close and resets, guarantee motor run up and in, can both make relevant parameter and its coupling during the slow-speed of revolution, thereby the economic and technical norms of assurance motor are optimized the most.
