Abstract: A rocker arm assembly comprises a first arm, a second arm, and a latch assembly. The first arm comprises a main cam interface end, a body comprising a shaft port configured to pivot on a rocker shaft, and a valve end configured to lift and lower when the main cam interface end is acted on by a cam lobe. The second arm is overlaid on the first arm. The second arm comprises a secondary cam interface end, a latch lip end, and a shell connecting the latch lip end and the secondary cam interface end. The shell is configured to pivot relative to the first arm. The latch assembly is mounted to the body. The latch assembly is configured to selectively latch and unlatch the first arm with respect to the second arm.

Abstract: A system and method for improving the functioning of a turbocharged diesel engine equipped with a cylinder deactivation system includes detecting when the turbocharged diesel engine is at risk of compressor surge, and then delaying the implementation of the cylinder deactivation. The delay may be a set period of time, or it may be determined by performing a set of instructions effective for estimating changes in intake manifold pressures over time if cylinders are deactivated, and then comparing the intake manifold pressure estimates to acceptable intake manifold pressure information. A formula for performing the required estimates is provided.

Abstract: A method for controlling vehicle speed comprises selecting an engine speed profile for a vehicle. Road grade data is received and processed to determine a road grade for the vehicle. Vehicle speed data is received and processed to determine a vehicle speed for the vehicle. A cylinder deactivation mode for a valvetrain of a multi-cylinder engine of the vehicle is selected. The cylinder deactivation mode comprises deactivating one or more intake valve, exhaust valve, and fuel injection for one or more cylinder of the multi-cylinder engine. The selected cylinder deactivation mode provides a controlled deviation from the selected engine speed profile at the road grade and vehicle speed.

Abstract: A method of providing a rocker arm set for a valvetrain includes providing a first rocker arm configured as a switching rocker arm for a first intake valve, and providing a second rocker arm configured as a fixed rocker arm for a second intake valve, the second rocker arm operating in a normal Otto cycle mode. The first rocker arm operates in a late intake valve closing (LIVC) mode where the first rocker arm is configured to close the first intake valve later than the second intake valve.
