NEWSLETTER May 2020 Thank you to all of our F.A.S.T. assemblers out there for what you do,…
ConSys will provide your company with electronic pedals for controlling the engine accelerator with the requirements of Euro-3 and Euro-4. Environmental standards Euro 3 began to operate in Russia on January 1, 2008.
In conventional engine control systems, the engine is operated by acting on the accelerator pedal, which is mechanically connected to the high-pressure fuel pump (High Pressure Fuel Pump – Diesel Engine). The force from the accelerator pedal to the high-pressure fuel pump is usually transmitted through the remote control cable, sometimes, in earlier designs, using mechanical rods. In modern engine management systems, remote control cables, and especially mechanical traction, are absent. The efforts of the driver when you press the pedal are recorded by the pedal position sensors and in the form of electrical signals, depending on its angular position, are transmitted to the electronic control unit (ECU). The proposed pedals use a non-contact sensor using the Hall effect, the characteristics obtained from which are a function of its angular position of the pedal. For protective or diagnostic purposes, in case of a malfunction of the main sensor, an additional sensor can be installed. Incoming and outgoing voltage characteristics are set during the manufacture of pedals and are presented in the form of graphs for calculating the stroke or angular movement of the pedal.
For vehicles with automatic transmission, a kick-down sensor can be installed also.
Coordination of the use of ConSyS electronic pedals:
|Coordination of the use of the electronic pedal by Avtodiesel OJSC Confirmation of approval by the Avtodiesel OJSC of the use of the EAAX-EXP0029P-01 electronic pedal on buses of PAZ LLC with YaMZ-5342 engines, as well as the EXP00025 electronic pedal for cars of AvtoKrAZ HC with YaMZ-536 and YaMZ-650/651 engines. In terms of electrical characteristics, the pedals EAAX-EXP0029P-01, EXP00025 developed by the control panel – CONSYS control panel are identical to those used at present in ESM of YaMZ-530 and YaMZ-650 engines.|
|Coordination of the use of the electronic pedal by the Minsk Motor Plant OJSC Based on the BOSCH conclusion, OJSC MMZ confirms the compatibility of the electronic pedals ORSCHELN EAAXEXP00025, EAAX-EXP0029P-01 manufactured by ConSys control panel with the hardware of the EDC7UC31 electronic control unit installed on the engines of OJSC MMZ.|
The principle of operation of the proximity sensor:
If a current “I” passes through a silicon plate in a magnetic field whose magnetic induction vector “B” is perpendicular to the plane of the plate, then a potential difference called emf occurs on the faces parallel to the current direction Hall.
