US Classification:
123 9016, 123 9015, 123 9039
Abstract:
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.

US Classification:
123432, 123 9011, 123302, 123308
Abstract:
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.

International Classification:
F16H 7/08 F16H 7/12
US Classification:
474111, 474110, 474109, 474134
Abstract:
A camshaft drive system for an internal combustion engine includes a drive sprocket fixed upon a crankshaft of the engine and a driven sprocket fixed upon a camshaft of the engine. A flexible power transmission element extends between the drive sprocket and driven sprocket. A tensioning device for the flexible power transmission element includes a linear actuator and a number of movable contactors for engaging and tensioning both the slack side and the tight side of the power transmission element, such that proper phasing of the camshaft with respect to the crankshaft is maintained.

International Classification:
F02D 28/00 F01L 1/34
US Classification:
701105, 123 9017
Abstract:
A method for controlling an electric variable cam timing (VCT) actuator is disclosed. The method includes during engine shutdown, adjusting camshaft position with an electric VCT actuator to a target starting location, applying a first current to the electric VCT actuator to maintain the target starting location, and during engine startup before camshaft position feedback becomes available, applying a second current to the electric VCT actuator to maintain the target starting location.

Abstract:
Embodiments for routing exhaust in an engine are provided. In one example, an engine method comprises, during a first condition, firing a subset of cylinders and routing all exhaust from the subset of cylinders through a first exhaust manifold coupled directly to a catalyst and not a turbocharger, and during a second condition, firing all cylinders, routing a first portion of exhaust through a second exhaust manifold coupled to the turbocharger, and routing a second portion of exhaust through the first exhaust manifold. In this way, exhaust can be directly routed to a catalyst under some conditions.
