Filed:

Oct 16, 2006

Appl. No.:

11/581315

Inventors:

Stephen M. Wiley - East Peoria IL, US
Brian K. Garman - Groveland IL, US
Earl A. Pilgrim - Peoria IL, US
Scott A. Leman - Eureka IL, US

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

F01L 1/18

US Classification:

123 9039, 123 9016, 123 904

Abstract:

An engine that includes two intake and two exhaust valves for each cylinder is equipped for single valve constant lift engine braking. The exhaust valves may be actuated in a conventional manner via a rotating cam and a rocker arm coupled to a bridge that spans between the pair of exhaust valves. Engine braking is accomplished by actuating a brake actuator to hold one of the exhaust valves partially open, while the other of the two exhaust valves is allowed to close. Seating velocity of the non-braking valve is limited by including a second actuator button, namely a valve seating actuator, on the rocker arm that engages the valve bridge above the non-braking valve as it moves toward its closed position when the brake actuator is actuated.

International Classification:

F02D 13/04
F02D 13/06

US Classification:

123321, 123320

Abstract:

The present disclosure is directed to a method of retarding an engine. The method includes selectively retarding the engine in a first mode configured to produce a first level of retarding at a first intensity of noise by selectively opening at least one exhaust valve between ninety degrees and zero degrees of an engine crank angle prior to top-dead-center of a compression stroke. The method also includes selectively retarding the engine in a second retarding mode configured to produce a second level of retarding at a second intensity of noise by maintaining an opening of at least one exhaust valve throughout the entire compression stroke.

US Classification:

60295, 60286, 60303

Abstract:

A regeneration device is disclosed. The regeneration device may include a housing and a perforated plate. The housing may have a passage configured to receive a flow of combustion air, and a separate bore configured to receive an electrical device. The perforated plate may be mounted to the housing to at least partially define an air chamber. Furthermore, the regeneration device may include at least one purge passageway located to communicate combustion air from the air chamber with the bore.

G01M 17/00
F02D 35/02

US Classification:

123320

Abstract:

A system to prevent engine stalls for a machine having a power source is disclosed. The power source is in communication with a controller, which is configured to determine the temperature of the power source and compare the temperature of the power source to a predetermined threshold temperature. The controller is configured to disable power source braking if the temperature of the power source is less than the threshold temperature. The controller is further configured to determine the power source speed and the travel speed of the machine, and disable power source braking if the power source speed and machine travel speed are less than predetermined thresholds.

Abstract:

An regeneration system for use in a power system is disclosed. The regeneration system may include a source of intake air, an engine brake configured to reduce the speed of an engine by compression and release of the intake air, and a valve configured to divert a portion of the intake air to an auxiliary device. The regeneration system may further include a controller in communication with the engine brake and the valve. The controller may be configured to move the valve to reduce the portion of intake air diverted to the auxiliary device when the engine brake is active.
