Abstract: A cylinder head for an internal combustion engine has inlet and outlet valves for the charge cycle control in a combustion space of the cylinder head, which inlet and outlet valves are actuated by at least one camshaft. For providing a cylinder head system having the inlet valves and the outlet valves which is suitable for different internal-combustion engines with a manifold injection or a direct injection, the head system has constructional characteristics which are suitable for a first cylinder head variant with a manifold injection as well as for a second cylinder head variant with a direct injection. The second cylinder head variant is provided with injection nozzles installed from a longitudinal side which extend at an acute angle with respect to a plane extending between the second cylinder head variant and a cylinder housing when assembled on a cylinder housing.

Abstract: A cylinder head for a direct-injection spark-ignition internal combustion engine includes, for each cylinder, an inlet valve, an exhaust valve, a first receptacle, a second receptacle, and a third receptacle. The first, second, and third receptacles are respectively configured to receive an ignition device or an injection device. The first receptacle extends substantially parallel to the inlet valve. The second receptacle extends substantially parallel to the exhaust valve. A common camshaft is offset from a cylinder center plane and actuates the inlet valve and the exhaust valve via identically constructed valve actuating elements. The cylinder head is lightweight, compact and easy to assemble and is in particular suited for high performance engines.

Abstract: In a conventional internal combustion engine the cylinder wall constrains the connecting rod to a straight up and down motion. The wall of a valve-guide also constrains the valve movement to a straight up and down motion. In ACOFE, two staggered bellows constrain the connecting rod to a semi-straight up and down motion, and therefore eliminate the need for the cylinder. Two other smaller bellows constrain a valve to a semi-straight up and down motion, and therefore eliminate the need for the valve-guide.

Abstract translation: 在常规的内燃机中，气缸壁将连杆限制在直立的上下运动中。 阀导向器的壁也将阀门运动限制为直立的上下运动。 在ACOFE中，两个交错的波纹管将连杆限制在半直线上下运动，因此不需要气缸。 另外两个较小的波纹管将阀限制为半直的上下运动，因此不需要阀导轨。

Abstract: A cylinder head of a spark-ignition engine is divided into an upper cylinder head portion and a lower cylinder head portion by means of a division wall portion. An upper spark-plug hole is formed in the upper cylinder head portion, whereas a lower spark-plug hole is formed in the lower cylinder head portion. The relative position of lower spark-plug hole is based on the position of the spark plug screwed into a tapped hole formed in the lower cylinder head portion. The relative position of the upper spark-plug hole is based on engine parts mounted in the upper cylinder head. The axis of the upper spark-plug hole is thus designed to be offset from the axis of the lower spark-plug hole. Each of the upper and lower spark-plug holes has a tapered hollow portion in close vicinity to the division wall portion. Alternatively, the lower spark-plug hole is diametrically enlarged in comparison with the upper spark-plug hole, so that the lower spark-plug hole surrounds the entire circumference of the upper spark-plug hole.

Abstract: A multi-cylinder internal combustion engine includes an intake manifold having branch pipes connected to one side of a cylinder head and curved to allow the intake manifold to extend to directly above a cylinder-head cover, and intake-side spark plugs and fuel injectors which are incorporated in the cylinder head. The spark plugs are disposed outside a valve train chamber on a side of the valve train chamber where curved portions of the branch pipes are disposed, and the fuel injectors and ignition coils provided above the spark plugs are disposed between the valve train chamber and the curved portions in a direction normal to axes of the cylinders as viewed from a direction in which cylinders are arranged. The ignition coils are disposed so as not to overlap the branch pipes as viewed from a direction in which the ignition coils are attached to the cylinder head.
