Abstract: An internal combustion engine cylinder head camshaft bearing ladder 210, is provided which includes a first body with an aperture to facilitate threaded connection 202 of the body to a cylinder head 2 with a cut out 212 for receiving a cam shaft 67, the first body also having a pocket 218, and a solenoid actuator 220 positioned within the pocket 218 for activating a switchable rocker arm assembly 9.

Abstract: A cam cover gasket 207 is provided which includes a generally compliant first material 210 having an upper surface for contact with a cover 200 and a lower surface for contact with an engine head 2, a generally rigid bracket frame of a second material 222 connected with the first material 210, and a solenoid actuator 232 connected with the second material 222.

Abstract: A variable lift cylinder valve system for an internal combustion engine includes a poppet valve operated by a rocker arm which is articulated about a translational pivot having its placement determined by a control shaft which operates a control arm in contact with the translational pivot such that rotation of the control shaft produces translational motion of the pivot so as to control the lift ratio of the rocker arm.

Abstract: A barrel throttle valve assembly (20) for use in an air intake system of an internal combustion engine. The barrel throttle valve assembly (20) includes a barrel (32) mounted within a housing (22), with the barrel (32) preferably including an upstream orifice (42), and idle notch (44) and a downstream orifice (46) for controlling the flow of idle air through the valve when the barrel (32) is in a substantially closed position, thus increasing the sensitivity of the valve at idle conditions. Also, preferably, a seal (48) and spring (54) is employed to reduce air leakage around the barrel (32).
