摘要： An engine control device is configured to perform optimum combustion control according to environmental conditions when warming up of a catalyst for emission purification is required. The engine control device performs stratified combustion by the compression stroke injection at the time of startup, when warming up of the catalyst is required. However, under conditions of low air density, stratified combustion by compression stroke injection is prevented, and either homogenous combustion by intake stroke injection is performed, or double injection combustion by intake stroke injection and compression stroke injection is performed. Thus, the engine control device maintains starting properties and prevents adverse effects on engine operability.

摘要： An engine system is capable of switching between a first fuel injection mode, in which fuel is injected from a fuel injection valve 23 directly into a combustion chamber 6 in the compression stroke, and a second fuel injection mode, in which fuel is injected from the fuel injection valve 23 directly into the combustion chamber 6 in the intake stroke. A controller 30 determines the characteristic of the fuel that is supplied to the fuel injection valve 23, selects either the first fuel injection mode or the second fuel injection mode according to the fuel characteristic, and starts an engine 1 in the selected fuel injection mode.

摘要： During start-up of an in-cylinder fuel injection spark ignition engine (1), an engine controller (21) calculates a start-up fuel injection pulse width TIST on the basis of a cooling water temperature Tw, an engine rotation speed Ne, and a fuel supply pressure Pf to a fuel injector (8) (S1). When the fuel supply pressure Pf exceeds a required fuel pressure, the engine controller (21) executes stratified combustion by means of compression stroke fuel injection. By setting the required fuel pressure precisely in accordance with a start-up condition defined by the start-up fuel injection pulse width TIST and the engine rotation speed Ne, the opportunities for stratified combustion during start-up increase, and the amount of hydrocarbon discharge decreases.
