Abstract
An engine control equipment capable of activating a catalyst and preventing exhaust gas from deteriorating in order to early perform combustion by compressive self-ignition is disclosed. The engine control equipment is an engine control equipment including a catalyst for burning a mixed gas in a combustion chamber by compressive self-ignition and purifying exhaust-gas components in the combustion chamber and a controller for controller the catalyst which determines the activation of the catalyst and activates the catalyst in accordance with a determination result based upon determining the activation of the catalyst.
Claims21
Engine control equipment having a catalyst for burning a mixed gas in a combustion chamber by compression self-ignition and purifying exhaust gas components in the combustion chamber, comprising means for controlling the catalyst, including means for determining the activated state of the catalyst and means for activating the catalyst in accordance with the determination so as to inhibit the compression self-ignition and performing spark ignition in the combustion chamber until the catalyst is activated sufficiently.
Engine control equipment having a catalyst for burning a mixed gas in a combustion chamber by compression self-ignition and purifying exhaust gas components in the combustion chamber, comprising a catalyst controller configured to determine an activated catalyst state and a catalyst activator operative to activate the catalyst based upon the determined catalyst state such that compression self-ignition is inhibited and spark ignition is performed in the combustion chamber until the catalyst is activated sufficiently.
