Patent number: 8156926Abstract: A filtration system is disclosed. The filtration system includes a valve lid defining a chamber. The chamber is configured to extend substantially in a second direction. The filtration system also includes a filter element associated with a lower portion of the chamber. The filtration system further includes a passageway in flow communication with the lower portion of the chamber. The passageway is configured to provide flow communication for a mixture of oil vapor and crankcase fumes flowing into the chamber substantially in a first direction and substantially upward direction. The first direction is generally orthogonal to the second direction. The chamber is configured such that the flow of the mixture into the chamber results in at least a portion of the oil vapor collecting in the filter element, and at least a portion of the crankcase fumes flowing through the filter element.Type: GrantFiled: July 29, 2008Date of Patent: April 17, 2012Assignee: Caterpillar Inc.Inventors: James Richard Weber, Justin Werner McMenamy

Patent number: 7100552Abstract: A method of controlling a variable valve actuation system is provided. A cam assembly is operated to move an intake valve between a first position where the intake valve blocks a flow of fluid and a second position where the intake valve allows a flow of fluid. At least one operating parameter of the engine is sensed. A valve actuation period is determined based on the at least one operating parameter. A valve actuator is engaged with the intake valve to prevent the intake valve from returning to the first position in response to operation of the cam assembly. The valve actuator is released to allow the intake valve to return to the first position at the end of the determined valve actuation period.Type: GrantFiled: May 14, 2002Date of Patent: September 5, 2006Assignee: Caterpillar Inc.Inventors: Jason Kenneth Bloms, James J.

Patent number: 6928969Abstract: A method of controlling an engine is provided. At least one operating parameter of the engine is sensed. The engine is operated in a first mode in response to the sensed operating parameter being at one of a predetermined first set of conditions. In the first mode, a cam assembly moves an intake valve from a first position when a piston starts an intake stroke and the cam assembly returns the intake valve to the first position when the piston completes the intake stroke. The engine is operated in a second mode in response to the sensed operating parameter being at one of a predetermined second set of conditions. In the second mode, the cam assembly moves the intake valve from the first position when the piston starts an intake stroke and an actuator prevents the intake valve from returning to the first position in response to the cam assembly.Type: GrantFiled: May 14, 2002Date of Patent: August 16, 2005Assignee: Caterpillar IncInventors: Jason Kenneth Bloms, James J.
