Title:
ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/096746
Kind Code:
A1
Abstract:
Provided is an engine control device that comprises an engine (1), state quantity setting devices (23, 24, 43, 48, 54), a spark plug (25), and a controller (ECU 10). The spark plug ignites a fuel-air mixture at a prescribed ignition timing such that an unburned fuel-air mixture undergoes combustion via self-ignition after combustion of the fuel-air mixture has been started by ignition. The controller adjusts a heat amount percentage serving as an indicator relating to the proportion of the heat amount generated when a fuel-air mixture undergoes combustion via flame propagation with respect to the total heat amount generated when a fuel-gas mixture undergoes combustion inside a combustion chamber (17) by changing the ignition timing in accordance with the running state of the engine.
