Abstract: This control apparatus estimates a full combustion correspondence period CP, which is the period from an ignition timing SA to a combustion completion time CAe, and controls a VVT advancement amount (burnt gas quantity, overlap period, intake valve open timing) such that the estimated full combustion correspondence period CP coincides with a constant target full combustion correspondence period CPtgt. The full combustion correspondence period CP substantially maintains a one-to-one relation with the VVT advancement amount at which HC, CO2, etc. start to increase, even when the ignition timing SA changes. Thus, even when the ignition timing changes, the burnt gas quantity (overlap period) can be properly controlled. As a result, without increasing the discharge quantities of HC and CO, the discharge quantity of NOX can be reduced. In addition, pumping loss can be reduced, whereby fuel consumption can be improved.

Abstract translation: 该控制装置估计作为从点火正时SA到燃烧完成时间CAe的周期的全燃烧对应期间CP，并控制VVT前进量（燃烧气体量，重叠期间，进气阀开放正时），使得估计 全燃烧对应期CP与恒定目标全燃相关期CPtgt一致。 即使当点火正时SA改变时，全燃烧对应期间CP基本维持与HC，CO 2等开始增加的VVT提前量的一对一关系。 因此，即使当点火正时变化时，也可以适当地控制燃烧气体量（重叠期间）。 结果，在不增加HC和CO的排出量的情况下，可以降低NOX的排出量。 此外，可以减少泵送损失，从而可以提高燃料消耗。

Abstract: A supercharged engine has a geometric compression ratio ser to 16 or more and is designed to perform a compression self-ignition combustion under an air-fuel ratio leaner than a stoichiometric air-fuel ratio at least in a low engine speed range. On a lower engine load side than a given engine load within an engine operating region at which the compression self-ignition combustion is performed, a fresh air amount is reduced and an effective compression ratio (ε′) is increased, as compared with a higher engine load side than the given engine load within the engine operating region, and, on the higher engine load side than the given engine load, a supercharging pressure based on a supercharger (25) is increased to increase the fresh air amount, and the effective compression ratio (ε′) is reduced, as compared with the lower engine load side than the given engine load. This makes it possible to perform the compression self-ignition combustion under a lean air-fuel ratio in a wider engine load range to effectively enhance engine thermal efficiency, while eliminating a need for an operation of forcedly raising/lowering a temperature of fresh air.

Abstract: A system for controlling intake airflow of an engine includes a mode determination module, a throttle valve control module, and a valve actuation module. The mode determination module generates a mode signal based on an engine speed signal and an engine load signal. The mode signal indicates one of a spark ignition mode and a homogeneous charge compression ignition mode. The throttle valve control module generates a valve control signal based on the mode signal, a temperature signal, and a plurality of valve position signals that indicate positions of first and second throttle valves. The throttle valve control module controls the positions of the first and second throttle valves to regulate flow rates of intake air into an intake manifold of the engine via a heat exchanger based on the valve control signal. The valve actuation module actuates the first and second throttle valves based on the valve control signal.

Abstract: In an internal combustion engine control device, when the engine stops, a variable valve actuation device is controlled to change an operating mode of each of intake valves to a specific state where an all-cylinder valve closed period, during which the intake valves of all engine cylinders are all kept in their non-lifted states, occurs, and a crank position change mechanism is controlled to change a crankshaft-rotation stopped position to a crankangle included within the all-cylinder valve closed period. When restarting the engine, the variable valve actuation device is controlled to bring the operating mode of each of the intake valves closer to an engine-start desired lift characteristic suited to an engine condition, prior to cranking action.
