Zusammenfassung:	To suppress a significant change of software in a first ECU in a case of a change from an existing system to a bi-fuel engine control system.SOLUTION: An engine control system that controls the operation of a single engine by selectively switching between gas fuel and liquid fuel, comprises: a crank angle sensor that outputs a pulse signal according to a crank angle of an engine provided in the vehicle; a correction unit that corrects the pulse signal to an advance angle side or a retard angle side; and an ignition timing control unit that controls ignition timing based on the pulse signal corrected by the correction unit.SELECTED DRAWING: Figure 1 【課題】既存システムからバイフューエルのエンジン制御システムに変更する場合において、１ｓｔＥＣＵにおけるソフトの大幅な変更を抑制する。【解決手段】気体燃料及び液体燃料のいずれかの燃料を択一的に切り替えて単一のエンジンの運転制御を行うエンジン制御システムであって、車両に設けられたエンジンのクランク角度に応じたパルス信号を出力するクランク角センサと、前記パルス信号を進角側又は遅角側に補正する補正部と、前記補正部により補正された前記パルス信号に基づいて点火時期を制御する点火時期制御部と、を備える。【選択図】図１
