摘要： Suction unit for an engine of horizontal single-cylinder direct injection type intended for producing a swirl in a suction air stream by means of a helical intake port, wherein, firstly, the intake port is formed to be "S"-shaped with its mid-section linear and prolonged for increasing the inertia force imparted to the suction air stream without increasing the width of the cylinder head and, secondly, the linear mid-section of the "S"-shaped intake port is formed to continue smoothly into an helical section so that the suction air stream enters unattenuated and guided by the helical passage to swirl up to approx. 180.degree. under acceleration before it enters a combustion chamber and the powerful swirl thus produced is further developed as it advances toward the center of the combustion chamber.

摘要： A gas-mixture-ignition-time estimation apparatus for an internal combustion engine estimates the temperature of a premixed gas mixture for PCCI combustion (i.e., cylinder interior temperature Tg), while relating it to the angle CA, on the basis of a state quantity of the cylinder interior gas at the time of start of compression (CAin) (heat energy of the cylinder interior gas at the time of start of compression), the amount of a change in the state quantity of the cylinder interior gas attributable to compression in a compression stroke (minute piston work), and the heat generation quantity of a cool flame generated in PCCI combustion prior to autoignition (hot flame) (cool flame heat generation quantity Aqlto). A time when the cylinder interior temperature Tg reaches a predetermined autoignition start temperature Tig is estimated as an autoignition start time (Caig) of the premixed gas mixture related to PCCI combustion. Since the cool flame heat generation quantity Oqlto is taken into consideration, the autoignition start time related to PCCI combustion can be estimated accurately.

摘要： A pressure boosting unit (110) is provided in each fuel injection valve of an engine (1). A pressure of fuel to be supplied to the fuel injection valve from a common rail (3) is boosted as required. An ECU (20) causes low pressure injection to be performed with the pressure boosting unit 110 being in a non-operated state, and high pressure injection to be performed with the pressure boosting unit (110) being in an operated state, and the pressure of the fuel being maintained at a boosted pressure. Based on the result, the ECU (20) corrects a fuel injection period of the fuel injection valve. Also, after the correction of the fuel injection period is completed, fuel injection is performed before the pressure of the fuel reaches the boosted pressure after the pressure boosting unit starts to be operated. Based on the result, operation starting timing of the pressure boosting unit is adjusted.
