摘要： A control method of a spark ignition engine and a spark ignition engine capable of warming up an engine more promptly while promptly activating a catalyst are provided. Implemented is the control of igniting a mixture at an ignition timing that is set on a more lag side than an MBT, which is an ignition timing in which an output torque of the engine becomes maximum until the catalyst is activated after the engine is started. After the catalyst is activated, until the engine is warmed up control of increasing a ratio of burned gas contained in the mixture within the combustion chamber to be more than the ratio of the burned gas in the mixture during a first period, and control of igniting the mixture containing more burned gas than the burned gas in the first period are implemented.

摘要： Various systems and methods are disclosed for controlling an internal combustion engine system having an internal combustion engine, and a fuel injector which directly injects fuel into a combustion chamber of the internal combustion engine. One example method comprises, when a desired torque for the internal combustion engine system is in a first range, injecting a first stage fuel into the combustion chamber so that it ends during a middle stage of a compression stroke at the latest in a cylinder cycle; determining combustion of the first stage fuel initiated by its compression self-ignition; and injecting a second stage fuel into the combustion chamber in a period when the determined combustion of the first stage fuel continues at a timing determined so as to cause combustion of the second stage fuel with its compression self-ignition.

摘要： In a specified operating area including a low engine-speed and low engine-load area, an excess air ratio λ is set at a specified ratio which is two or greater and three or smaller and an ignition timing θig of a spark plug is set at a timing of MBT to provide the maximum torque as a normal combustion control (S4). In case a catalyst temperature Tc is lower than a predetermined first temperature T1 in this area, a control of retarding the ignition timing from the MBT timing and/or a control of decreasing the excess air ratio λ to a ration below the above-described ratio are executed (S6, S8, S9). Accordingly, the temperature of the catalyst can be prevented simply and effectively from decreasing excessively, maintaining combustion conditions to provide a properly high thermal efficiency.

摘要： Disclosed is a direct-injection spark-ignition engine designed to promote catalyst activation during cold engine operation. A fuel injection timing for a fuel injection period in an compression stroke (second fuel injection period F2) is set to allow a first fuel spray Ga injected from a first spray hole 40a to enter a cavity 34 in a piston crown surface 30, and allow a second fuel spray Gb to impinge against a region of the piston crown surface 30 located closer to an injector than the cavity 34, so as to cause the second fuel spray Gb having a lowered penetration force due to the impingement to be pulled toward the cavity 34 by a negative pressure generated in the cavity 34 as a result of passing of the first fuel spray Ga therethrough. The direct-injection spark-ignition engine can maximally hold an injected fuel spray around a spark plug to reliably stabilize a combustion state in a combustion mode for promoting catalyst activation during cold engine operation, while enhancing combustion efficiency in a homogenous combustion mode during normal engine operation.

摘要： Methods and systems for controlling an internal combustion engine are provided. One example method may include closing an intake valve later during a cylinder cycle than a timing with which an amount of air inducted into a cylinder from an air intake passage would be maximized, and earlier during the cylinder cycle as a desired amount of air to be inducted into the cylinder increases, while an engine is operating at a given engine speed. The method may further include closing the intake valve earlier during a cylinder cycle as the engine speed increases when the desired amount of air to be inducted into the cylinder is at a maximum.
