Abstract: A waste heat recovery system connects a working fluid into passages formed within an internal combustion engine. The fluid passages transport the working fluid to high temperature areas of the engine, raising the temperature of the working fluid near the phase change point or above the phase change point. The heated working fluid drives an energy conversion portion located downstream from the engine. The heat absorbed by the working fluid decreases the load on an engine cooling system as well as driving an energy conversion portion, improving fuel efficiency.

Abstract: A high-efficiency mechanism for variable valve actuation with increased engine architecture applicability is described. The high efficiency mechanism introduces an intermediate lever having a secondary cam profile forming a variable oscillating cam between a rotating camshaft and a rocker arm.

Abstract: Rib configurations for increasing the structural efficiency of a cylinder head, which relates to a peak combustion pressure capability of the cylinder head. In addition to increasing peak combustion pressure, the rib configurations may also improve sealing of the cylinder head and may improve the durability of an associated cylinder head gasket.
