Abstract: A variable valve device can change valve operations of a cylinder head in which a cam chain is disposed at a center in a predetermined direction where cylinders are arranged and spark plugs are arranged by recessing outer walls on both sides in the direction in a concave shape. The device includes, for each cylinder, a rocker shaft extending along the direction, rocker arms supported by the rocker shaft, a connecting pin disposed in a pin hole of one of the rocker arms, a return pin disposed in a pin hole of the other of the rocker arms, a pressing member that causes the connecting pin to push the return pin, and a repulsive member that causes the return pin to push back the connecting pin, and the pins and the members are separated from the plug in a direction orthogonal to the direction in a plan view.

Abstract: A split-cycle internal combustion engine includes a variable displacement compressor having two or more cylinders, an adjustment mechanism for varying the displacement volume of the compressor and possibly the phase between the compressor and the motor, and a rotary motor having two or more expansion chambers. A passage valve system located between the compressor and the motor transfers working fluid and combustion exhaust products, and, in addition, mechanically and thermally isolates the compressor from the high pressures and temperatures present in the motor.

Abstract: Disclosed is a method for determining the state of rotation of a camshaft of a vehicle engine, notable in that the method for determining the state of rotation of the camshaft determines that the state of rotation of the camshaft is “in the process of stalling”, corresponding to an intermediate state of rotation, when the time elapsed since the last detection of a camshaft wheel tooth-front by the sensor exceeds Tcam_cal, Tcam_cal being defined as the theoretical length of time needed for the camshaft wheel to cover an angular distance equal to the maximum angular distance separating two successive camshaft wheel tooth-fronts at a camshaft rotational speed corresponding to a predetermined low engine speed higher than the minimum engine speed tolerated by the engine.

Abstract: A control device for an internal combustion engine includes an air-fuel ratio controller to execute a stoichiometric operation in which an air-fuel ratio of an air-fuel mixture in a combustion chamber of the internal combustion engine is set to a stoichiometric air-fuel ratio and a lean operation in which the air-fuel ratio is set to an air-fuel ratio leaner than the stoichiometric air-fuel ratio. A ignition timing controller is to calculate at least one ignition timing control parameter based on a laminar combustion velocity and to control an ignition plug provided in the combustion chamber to ignite based on the at least one ignition timing control parameter in a transitional state between the stoichiometric operation and the lean operation.

Abstract: An adjustable camshaft for a valve drive of an internal combustion engine may include an inner shaft extending through an outer shaft with a cam element disposed on the outer shaft. The cam element may be connected rotationally conjointly to the inner shaft. The cam element may have a shaft passage with an internal bearing surface, which, together with a bearing surface on an outer side of the outer shaft, forms a plain bearing arrangement for the rotatable arrangement of the cam element on the outer shaft. The bearing surface on the outer side of the outer shaft and/or the internal bearing surface of the shaft passage of the cam element may include one or more sections with a spherical shape.
