Embodiment Construction

[0015] Dual-fuel engine throttle opening detection device of the present invention, such as figure 1 As shown, it includes a rotary potentiometer 7 and an oil volume adjustment lever 1 connected with the throttle pull rope 4. A linkage swing rod 6 is provided on the rotating shaft of the rotary potentiometer 7, and the oil volume adjustment lever 1 is linked with the linkage. The pendulum 6 is connected via a transmission pull rope 5, the length AC of the transmission pull rope 5 is between the rotation axis center D of the rotary potentiometer 7 and the rotation fulcrum 3 (point B) of the oil quantity adjustment lever 1 The distance BD is equal, the distance CD between the connection point C of the transmission pull cord 5 and the linkage swing lever 6 to the center D of the rotating shaft is the same as the connection point 2 (A point) to the pivot point 3 (point B) with the same distance AB.

Abstract

The invention relates to a dual-fuel engine accelerator opening detection device and an installation method of the dual-fuel engine accelerator opening detection device. The dual-fuel engine accelerator opening detection device comprises a rotating potentiometer and an oil mass adjustment lever connected with an accelerator pull cord. A linkage oscillating bar is arranged on a rotating shaft of the rotating potentiometer. The oil mass adjustment lever is connected with the linkage oscillating bar through a transmission pull cord. The length of the transmission pull cord is equal to the distance between the center of the rotating shaft of the rotating potentiometer and a rotating fulcrum of the oil mass adjustment lever. The distance between the point of junction of the transmission pull cord and the linkage oscillating bar and the center of the rotating shaft is equal to the distance between the point of junction of the transmission pull cord and the oil mass adjustment lever and the rotating fulcrum. According to the dual-fuel engine accelerator opening detection device and the installation method of the dual-fuel engine accelerator opening detection device, the fact that the rotation angle of the rotating potentiometer truly reflects actual accelerator opening information of an engine can be ensured, a reliable linear relation between accelerator opening and output signals of the rotating potentiometer is kept, and accuracy of detection of the accelerator opening is improved.

Description

technical field [0001] The invention relates to the technical field of engine throttle position detection, in particular to a dual-fuel engine throttle opening detection device and an installation method thereof. Background technique [0002] To convert a vehicle diesel engine into an electronically controlled dual-fuel engine, the most critical basic information of the electronic control system is to accurately obtain the driver's throttle opening signal and the engine's speed signal. For a vehicle diesel engine with mechanical speed regulation, the driver's willingness to open the throttle finally acts on the throttle speed control rod that controls the position of the oil quantity rack through the pull rope. proportional to the stroke. In the above-mentioned diesel engine control system, the general detection method of the accelerator opening position is: install a pedal position sensor under the accelerator pedal in the cab to directly extract the pedal opening signal. ...
