摘要： In a compression ignition engine employing a variable valve actuation mechanism variably adjusting an intake valve characteristic including at least one of an intake valve lift and an intake valve closure timing, a control system operates to temporarily lower an effective compression ratio of the engine by controlling the intake valve characteristic during a cranking period of cold starting operation. At a point of time when a predetermined cranking speed threshold value has been reached owing to a cranking speed rise, the effective compression ratio is risen by controlling the intake valve characteristic. After combustion of the engine has been stabilized, the intake valve characteristic is brought closer to a desired value determined based on engine operating conditions by way of closed-loop control.

摘要： The pressure prevailing in a variable volume chamber which controls the compression ratio developed by a piston, is used control the movement of a valve which regulates the supply and draining of the chamber. During high load the high pressure is used to drain the chamber while under light load the lower pressure permits the chamber to be supplied with hydraulic fluid in a manner which tends to fill the same during induction phases and the like when the pressure in the cylinder is low.

摘要： To induce high compression engine operation hydraulic fluid is fed into a variable volume chamber defined between an outer piston and an inner one which is reciprocatively disposed therein via a supply passage which includes a one-way valve. When low compression engine operation is required the pressure supplied to a valve chamber in which a spool valve is disposed is increased to the point whereat the spool valve moves to a position wherein the supply passage is closed and a drain and transfer passages are opened. The drain passage leads directly to the cylinder bore so as to enable the hydraulic fluid in the variable volume chamber to be vented unrestrictedly. The transfer passage permits a small amount of hydraulic fluid to flow through the variable volume chamber to the drain passage in a manner which cools the same and prevents degradation of the hydraulic fluid retained in the one-way valve and the like.
摘要翻译：为了引起高压缩发动机操作，液压流体被供给到限定在外活塞和内部活塞之间的可变容积室中，所述可变容积室通过包括单向阀的供应通道往复地设置在内部活塞中。当需要低压缩发动机运转时，供给到其中设置有滑阀的阀室的压力增加到滑阀移动到供给通道关闭并且排出和输送通道打开的位置的点。排水通道直接通向气缸孔，以使可变容积室中的液压流体不受限制地排放。传送通道允许少量的液压流体以可冷却的方式流过可变容积室到排放通道，并防止保持在单向阀等中的液压流体的劣化。

摘要： A parallel guide portion as an integral structure of a sprocket and a vane, as well as a slant guide portion, are arranged alternately on the same circumference, with circumferential gaps being formed between said guide portion and the parallel guide portion, said guide portion having a shape such that the circumferential gaps become smaller in one axial direction of a cam shaft. Wedge members are disposed in the circumferential gaps respectively and are moved in one axial direction to fill up the circumferential gaps, thereby fixing the phase between the sprocket and the vane into a locked state. The wedge angle of each wedge member is set sufficiently small and, by utilizing varying torques acting on the cam shaft, said members are each moved and locked in one axial direction with a spring. Said members are actuated in an opposite axial direction with oil pressure to release the locked state, thereby permitting a phase angle control. By utilizing a varying torque acting on the cam shaft, the phase of the cam shaft is returned for itself to an intermediate position and is locked without looseness.
