A poppet valve operating system for an internal combustion engine features variable valve lift and camshaft phasing. A planetary phaser uses control inputs which are shared with a variable lift mechanism. The phaser adjustment and the variable lift mechanism are controlled by a single positioning motor.

Poppet cylinder valve operating system for internal combustion engine

An intake and exhaust system for a dual mode HCCI engine, which provides superior intake temperature control and homogeneity for engine operation in SI and HCCI modes, as well as during transition between SI and HCCI modes and vice-versa. The system includes adjusted intake cam movement event lengths for intake valve operation at specified modes of operation. The system further includes at least one cam profile switching device operatively connected to intake and exhaust valves in an engine for controlling event length, maximum lift, and valve opening/closing timings for the intake and exhaust valves. The system yet further includes a bifurcated intake system and camless valve actuators for controlling intake valves for facilitating operation in SI or HCCI modes, as well as transition between SI and HCCI modes and vice-versa.

Method and apparatus for controlling operation of dual mode HCCI engines

A poppet valve operating system for an internal combustion engine includes a finger follower which is driven by an intermediate rocker. The intermediate rocker selectively converts motion imparted by a drive cam into either a purely translational trajectory, or into a mixed translational and rotational trajectory, so as to open a poppet valve which is ultimately actuated by a finger follower interposed between the intermediate rocker and the valve.

Cylinder valve operating system for internal combustion engine

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.
