摘要： A cam-switching device switches between first and second cams provided so as to correspond to intake exhaust valves of an engine. In a case of switching from the first cam to the second cam, a cylinder resting unit stops the opening and closing operations of the intake and exhaust valves in the same combustion cycle, and a cam shaft moving unit starts sliding the cam shaft in a first cam angle range. In a case of switching from the second cam to the first cam, the cylinder resting unit stops the opening and closing operations of the intake and exhaust valves in the same combustion cycle, and the cam shaft moving unit starts sliding the cam shaft in a second cam angle range.

摘要： A piston and method is provided that inhibits the potential catastrophic damage to an internal combustion engine, thereby reducing the risk of costly damage to the engine. The piston includes a piston body having an upper combustion surface separated from an internal cooling chamber by a wall. The a pocket extends into the upper combustion surface to a closed bottom surface of the wall. A tubular member is disposed in the pocket. The tubular member extends upwardly from the upper surface. Should a valve head drop from its normal operating position, the valve head impacts the tubular member and forms a blow-by through passage extending from the upper combustion surface into the cooling chamber.

摘要： The invention relates to an internal combustion engine, especially a diesel engine, especially of a motor vehicle, with at least one working cylinder, wherein each working cylinder has at least two inlet valves and at least one outlet valve assigned thereto, at least two camshafts (16, 18) being provided, of which at least one camshaft (16, 18) actuates at least one inlet valve and also at least one outlet valve. On at least one camshaft (18), which actuates at least one inlet valve and also at least one outlet valve, an is arranged an adjuster (28) which adjusts valve control times of the inlet and outlet valves assigned to this camshaft (18), optionally earlier or later, relative to the valve control times of the at least one other camshaft (16).

摘要： A system for controlling valve opening/closing timing that allows an unlocking operation to be reliably performed is configured. When extracting a lock member from a recess, a second control valve is set to an unlock position, a first control valve is set to a predetermined position, and a relative rotation phase is displaced. As a result, the relative rotation phase is displaced in a direction opposite to the direction of displacement by cam average torque from a camshaft. Afterward, by setting the first control valve to a neutral position, the relative rotation phase is displaced by the cam average torque, and when this displacement occurs, a state in which the lock member is separated from an inner wall of the recess is created, thus facilitating extraction of the lock member from the recess.

摘要： An apparatus is provided for controlling an intake valve of a vehicular internal combustion engine. The apparatus includes a variable valve operating mechanism configured to vary a valve lift and a valve phase angle of the intake valve, and a controller. The controller calculates a desired first target value at a current engine operating condition, a reacceleration estimated value based on an engine rotational speed and estimated operating load upon reacceleration, and a second target value at which engine torque is equivalent to engine torque at the first target value. The controller sets the first target value as a control target value, and then switches the control target value to the second target value when a minimum clearance between the intake valve and a piston is determined to become less than a permissible value during variation of the intake valve from the first target value toward the reacceleration estimated value.
