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: There is provided a method of starting an internal combustion engine having a combustion chamber and an intake valve which opens during an intake stroke of an engine cycle to allow air to be inducted into the combustion chamber. The method comprises cranking the internal combustion engine with advanced closing timing and a reduced lift of the intake valve without combustion of air and fuel in the combustion chamber from a stroke of the engine cycle prior to a first intake stroke of the combustion chamber since an engine start request, starting combustion of air and fuel in the combustion chamber after the first intake stroke, and retarding closing timing of said intake valve from the advanced closing timing and increasing the valve lift after the combustion is started. Accordingly, air charge in the combustion chamber may increase properly conforming to the engine speed increase caused by the combustion. Therefore, the torque derived from the combustion of the charged and fuel may increase the engine speed moderately after the beginning of the combustion.

Abstract: A turbo-charged internal combustion cylinder assembly includes a combustion chamber which may be communicably connected to a compressor via an intake port through an intake manifold and aftercooler so the compressor may provide pre-combustion gases to the combustion chamber when the intake valve is open. An exhaust port communicably connects the combustion chamber to an exhaust manifold. An exhaust valve may open to exhaust post-combustion gases to the exhaust manifold while an intake valve is substantially closed, and the exhaust valve may open to admit post-combustion gases to the combustion chamber while the intake valve is substantially open and an exhaust port pressure in the exhaust port is higher than a combustion chamber pressure in the combustion chamber. A fuel injector may admit fuel to the combustion chamber. A spill valve may control a rate of fuel injection to the combustion chamber, the spill valve having a first position providing a maximum fuel injection rate, a second position providing a substantially zero fuel injection rate, and at least one intermediate position providing an intermediate fuel injection rate between the maximum fuel injection rate and the zero fuel injection rate.

Abstract: The invention relates to a valve control for actuating at least one valve, especially an inlet or outlet valve of an internal combustion engine, wherein the dimension of the valve lift of the at least one valve corresponds to a superposition of two cam profiles which can be adjusted in phases in relation to each other and are displaced synchronously. The aim of the invention is to improve the construction and functioning of the valve control. As a result, a guiding means between an intermediate element and the first cam profile is embodied as third cam profile which is formed in a complementary manner with respect to the first cam profile and rotates in a synchronous manner therewith.

Abstract: A drive of a variable valve lift mechanism for driving a control shaft controlling a variable valve lift mechanism provided between an engine valve and an engine valve operating cam in order to change lift amount of the engine valve, comprises: a rotational force generating actuator; power conversion means for converting a rotational force of the rotational force generating actuator into a pivoting force of the control shaft; and a casing containing the power conversion means with the rotational force generating actuator coupled to an outer face of the casing. One end of the control shaft protrudes outward from one side of an engine body. The casing into which one end of the control shaft is inserted is attached to the one side of the engine body through fixing means which can be repeatedly attached and detached. Thus, it is possible to avoid the engine body from being complex and improve maintainability.
