Abstract
The utility model discloses a motorcycle electronic fuel injection throttling valve body with a temperature and pressure sensor, and relates to an air flow device for an engine of a motor vehicle. The throttling valve body consists of a cavity, a throttling valve sheet in the cavity, a throttling valve shaft for fixing the throttling valve sheet, an idling bypass flow passage and a torsion mechanism, and is characterized in that: an outlet section of the cavity is provided with a through hole serving as a probe hole; a bushing is formed integrally extending from the through hole on the outer wall of the cavity in the radial direction; a seal ring is sleeved on a front probe of a temperature and pressure sensor probe body, and then the front probe is elastically and hermetically sleeved in an inner hole of the bushing; and the probe body is pressed through a zigzag pressing plate and is fixed in a threaded hole on the outer end face of the bushing through a screw. The throttling valve body has the advantages that: the temperature and pressure sensor is arranged on the throttling valve body, so that the information is stably acquired, the information accuracy is improved, and the air flow, the fuel injection stability and the service life of the mechanism are guaranteed.
Description
Technical field:
The utility model relates to the air mass flow device that motor car engine is used, especially for the motorcycle electric spraying throttle-valve body.
Background technique:
In fact EFI throttle-valve body assembly is exactly an air-flow control device at present, its position transducer can be used to monitor the actual aperture location status of closure, and be convertible into electrical signal transfer to the Motronic control maps control module, engine idle air flow control valve can the direct drive controlling of launched organic electronic control module, and the feedback signal by engine rotational speed signal realizes the charge flow rate of the idle operating mode of motor is adjusted closed loop control.And can increase air inflow to appropriateness under the unexpected increase load condition, guarantee engine idle speed stability, and in the motor dynamic behavior, by position sensor signal, the oil spout of prompting oil sprayer makes gasoline and air be able to abundant mixing, reach best chemically correct fuel, the running that can realize the motor transient working condition is more steady, help the raising and the optimization of transient working condition cornering ability, and Carburetor does not have this function; The motorcycle throttle-valve body is made up of with bypass runner, twist mechanism throttle plate pin, the idling of the throttle blade in cavity, the cavity, fixed knot bulla; Twist mechanism is made up of the outer section of throttle plate pin axis body, torsion spring, rope support, initial corner location adjusting device, handgrip is by the rotation of mild steel rope pulling rope support, thereby drive throttle plate pin, throttle blade rotation, air mass flow in the throttle blade aperture decision cavity, torsion spring is as the throttle blade return spring.Under idling mode, as long as micro-air supplies with, this moment, the throttle blade aperture was very little or close, and relied on bypass runner air supply.
The bypass flow passage structure is projection body of chamber outer wall disjunctor extension, projection body top is provided with sleeve-port, projection body bottom is provided with blind hole shape Flow-rate adjustment hole, adjustment hole middle-end and bottom are provided with the up and down tilting hole that is communicated with the Flow-rate adjustment hole respectively, in the another port in tilting hole be on the upper cavity inwall of throttle blade top; The another port in tilting hole is on the lower chamber inwall of throttle blade below down; A stepper motor idle valve inserts the sleeve-port location, and flow is regulated the air mass flow of bypass runner by the closed loop control of stepper motor idle valve.
The Motronic control maps control module also needs to enter after gasoline and the air mixing temperature, the pressure information that this period of motor gathers mist of oil and regulates the air mass flow and the oily discharge rate of idling mode, working state.Usually the serviceability temperature pressure transducer inserts the avris trepanning on the motor oil-feed flow path wall that the throttle-valve body cavity is communicated with, and with " it " font pressing plate by screw on motor oil-feed runner outer wall, sensor probe stretches into oil-feed runner image data.It is fast that the problem that this structure exists is that engine cylinder temperature, pressure degree changes, fluctuation is big for the throttle-valve body cavity, there are simultaneously space, position difference between the two, also cause the variable quantity in the temperature pressure sensing process, and relativity temperature, pressure fluctuation causing greatly electronic control module regulation and control speed in frequency strengthens, then cause stepper motor idle valve, air flow control valve etc. and act frequently, influence its precision and service life.Sensor is installed on the motor simultaneously, takies motor gabarit space.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of motorcycle electric spraying throttle valve body with temperature and pressure transmitter is provided.
Scheme of the present utility model is: throttle-valve body is made up of with bypass runner, twist mechanism throttle plate pin, the idling of the throttle blade in cavity, the cavity, fixed knot bulla; It is characterized in that: offer a through hole as probe hole in the cavity outlet section, described through hole is at chamber outer wall disjunctor sleeve pipe that extends radially, elastic packing was inserted in the described cover pipe orifice after the front-end probe fit of a temperature and pressure transmitter sonde body seal ring, sonde body passes through the pressing of " it " font pressing plate, and is screwed in the tapped hole of sleeve pipe exterior edge face.
Advantage of the present utility model is: it is stable that temperature and pressure transmitter is installed on the throttle-valve body Information Monitoring, and precision of information improves, and guarantees air mass flow, oil spray stability and mechanism's service life.
