Abstract: A method for engine braking on a type III valvetrain diesel engine comprises, on a first downstroke of a reciprocating piston, deactivating a normal intake lift profile on a first intake valve to implement a deactivated intake profile. Before a first upstroke of the reciprocating piston completes, a late intake valve closing lift profile is actuating on a second intake valve and beginning an engine brake lift profile on a first exhaust valve. On a second downstroke of the reciprocating piston, the engine brake lift profile on the first exhaust valve is completing and a normal exhaust lift profile is deactivating on a second exhaust valve to implement a deactivated exhaust profile on the second exhaust valve. Before a second upstroke of the reciprocating piston completes, a second engine brake lift profile is beginning on the first exhaust valve.

Abstract: A rocker arm can comprise a forked outer arm assembly and a T-shaped inner arm assembly comprising an inner arm body comprising a valve side, a latch side, a bearing hole on the valve side, and a latch body on the latch side, the latch body comprising inner arm extensions extending away from the latch body. A pivot axle can connect the outer arm assembly to the inner arm assembly so that the inner arm assembly is configured to pivot with respect to the outer arm assembly. A latch assembly can comprise a latch configured to selectively extend to and retract from a latch seat on the latch body to selectively lock the inner arm assembly with respect to the outer arm assembly or unlock the inner arm assembly to pivot within the outer arm assembly.

Abstract: An engine roller lifter for use in a leak-valvetrain of an internal combustion engine includes a body, a roller and an anti-rotation plug. The body includes an outer peripheral surface configured for sliding movement in a bore provided in the engine. The bore is supplied oil by an oil passage communicating therewith. The body defines an opening. The roller bearing is rotatably mounted to the body and is configured for rolling contact with an engine camshaft. The anti-rotation plug is received at the opening and has a plug body including an anti-rotation protrusion that extends radially beyond an outer peripheral surface of the plug body. The anti-rotation plug can be staked into the opening of the body.

Abstract: A method for operating a 6-cylinder engine connected to a driveline including a transmission. The method includes: monitoring a rotational speed of a crankshaft of the 6-cylinder engine: monitoring a gear selection of the transmission; and operating the 6-cylinder engine in one of Order 3, Order 1.5 or Order 1 based on whether the selected Order avoids operating the 6-cylinder engine at a critical speed that corresponds to a natural harmonic frequency of the driveline, wherein priority is given to operating in Order 1.5, Order 1 then Order 3, in that order.

Abstract: A method of operating a system including a hydrogen internal combustion engine and a supercharger between a normal operating mode and an engine braking mode. In the normal operating mode, the supercharger operates at a first rotational speed to deliver air to an intake manifold of the engine. In the engine braking mode, the supercharger operates at a second rotational speed to deliver air to the intake manifold and a restriction is provided to increase a pressure ratio across the supercharger.
