Patent number: 7815533Abstract: 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.Type: GrantFiled: September 18, 2006Date of Patent: October 19, 2010Assignee: Ford Global TechnologiesInventors: Gary A. Vrsek, Michael Magnan, Kim Ku

Patent number: 7258104Abstract: 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.Type: GrantFiled: March 10, 2006Date of Patent: August 21, 2007Assignee: Ford Global Technologies, LLCInventors: Jialin Young, Brad Boyer, Kim Ku, Fang Shui, William Stockhausen

Patent number: 6932035Abstract: 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.Type: GrantFiled: January 28, 2005Date of Patent: August 23, 2005Assignee: Ford Global Technologies, LLCInventors: Fang Shui, Kim Ku
