Title:
ROTATION CONTROL SYSTEM FOR BI-FUEL ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/084368
Kind Code:
A1
Abstract:
The purpose of the present invention is to prevent a drop in engine rotation speed and loss of stable engine rotation in a bi-fuel engine when the fuel that the bi-fuel engine is running on is switched. A relay (81) that is switched by a changeover signal from a fuel switching device (7) and an electrical resistance (82) are series connected in an input circuit (8) that inputs water temperature data for engine cooling water detected by a water temperature sensor (104) to an electronic control unit (ECU) (5). When the fuel to be used is switched, the relay (81) is operated so that the electric resistance (82) is added to the water temperature data from the water temperature sensor (104) to produce a value that increases the target rotation speed such that the rotation speed is controlled to a stable rotation speed.
