Abstract: A variable valve actuation system for providing discrete exhaust and intake valve lift profiles for various operating modes of an internal combustion engine. The variable valve actuation system includes exhaust and intake rocker assemblies, exhaust and intake hydraulic extension devices operatively coupling corresponding rocker assemblies with respective engine valves and exhaust and intake control valves for selectively supplying the pressurized hydraulic fluid to the extension devices so as to independently switch them between a pressurized condition and a depressurized condition. The engine further includes an exhaust brake provided to initiate a small lift of the exhaust valve during the engine braking operation while the exhaust extension device maintains the exhaust valve open during a compression stroke for bleeder-compression release braking. The exhaust and intake valves can be adjusted independently to provide combinations of valve lift modes.

Abstract: A line of small internal combustion engines, including twin cylinder engines and single cylinder engines. The engines each include a crankcase, and one or more cylinder members attached to the crankcase, the cylinder members being separate components from the crankcase. A number of different crankcases are provided for various types of single and two cylinder engines, the crankcases having common mounting structure to which the cylinder members may be attached. Thus, the manner in which the cylinder members are attached to the crankcases is the same for each of the different types of crankcases. Two different types of cylinder members are provided, one having a side valve or “L-head” valve train, and the other having an overhead cam (“OHV”) valve train. The cylinder members are therefore modular components which may be selectively used in a variety of different types of engines.

Abstract: A method for generating an acceleration profile for a valve operating cam of an internal combustion engine varies an adjustment point of an initial draft acceleration profile curve such that a determinant of a set of equations defining valve motion constraints and scaling factors is forced to zero. The equations may then be solved for values of the scaling factors which are applied to the initial draft acceleration profile curve to generate a desired profile which satisfies valve motion constraints.

Abstract: Method and arrangement for delivering EGR gas to combustion spaces in a multi-cylinder, four-stroke internal combustion engine. Each cylinder, with an associated piston, has at least one inlet valve and at least one exhaust valve (10) for controlling fluid interconnection between the combustion space in the cylinder and an intake system and an exhaust system, respectively. A rotatable camshaft (18) having a cam curve (23) is designed to interact with a cam follower (17) for operation of the exhaust valve (10) during a first opening and closing phase. The cam curve (23) is also designed to interact with a second cam follower (20) during a second opening and closing phase which is phase-offset in relation to the first aforementioned opening and closing phase. This configuration facilitates the cylinder being connected to the exhaust system during the induction stroke, once the exhaust stroke is completed.
