    Abstract: A vehicle may include a drive axle, an engine assembly, a coupling device, and an engine load management system. The engine assembly may include a valvetrain including a fixed-lobe camshaft and intake and exhaust valves supported by the engine assembly. The fixed-lobe camshaft may include a first lobe engaged with the intake valve to open the intake valve and a second lobe engaged with the exhaust valve to open the exhaust valve. The first and second lobes may be fixed relative to one another to define a constant valve overlap condition that provides for opening of the intake valve before the exhaust valve is fully closed, creating an engine operating condition that results in combustion instability below an engine load limit. The engine load management system may be in communication with the engine to prevent engine operation below the engine load limit.

    Abstract: A valve train for use in an engine is provided. The valve train includes a rocker arm assembly having a valve side arm and a cam side arm. A valve is coupled to the engine and is in contact with the valve side arm. A pushrod is reciprocatable by a camshaft and is in contact with the cam side arm. An overload feature is located on at least one of the rocker arm assembly or the pushrod. The overload feature has a reduced cross-sectional area calibrated to activate at a predefined load.

    Abstract: An internal combustion engine includes a plurality of cylinders each having intake and exhaust valves and at least one camshaft timed to operate the valves with a high performance fixed overlap. Each camshaft has a cam phaser controlled to equally vary the intake and exhaust valve timing for superior full throttle performance over the engine speed range; Valve deactivation mechanisms operate to deactivate up to half the cylinders during idle and light load operation for increasing fuel efficiency and emission control and maintaining stable operation of the operating cylinders. The engine may also be started with half the cylinders cut out and then run with stable operation in this mode during idle and light load because the increased load on the operating cylinders gives stable operation with an increased valve overlap permitting increased performance and emission control at higher load operation on all the cylinders.

    Abstract: A method for extending the operating range of engine fuel injectors fed by a pressurized fuel system includes operating the fuel system at a controlled lower fuel pressure during engine operation in a lower power range, and operating the fuel system at a controlled higher fuel pressure during engine operation above the lower power range. An engine embodying the method may include a fuel distributor connected with the injectors for supplying the pressurized fuel and a pressure control operative in response to a prescribed engine condition, such as supercharger boost pressure, to maintain injector fuel supply pressure at a lower value during engine operation in a lower portion of the power range and at a higher value during engine operation in a higher portion of the power range. The dual or multiple fuel pressures provide greater fuel output for increased power in the higher power range with consistent fuel delivery for stable idle and engine operation in the lower power range.
