Abstract: An fresh air/exhaust gas compact mixer and method for mixing fresh air with exhaust gases, is provided. The mixer includes a main body, an air inlet for receiving fresh air fluidly connected to an air intake passage within the main body, an exhaust gas inlet for receiving exhaust fluidly connected to an exhaust gas passage within the main body. The mixer also includes a bifurcation within the air intake passage for directing the flow of air through the passage, wherein the bifurcation decreases a cross section of the air intake passage downstream from the air inlet, thereby increasing the air velocity exiting the air intake passage. The narrowed cross section creates a localized vacuum, encouraging an increased flow of exhaust gas through the mixer, and creating superior mixing of the fresh air with the exhaust gases prior to exiting the mixer.

Abstract: A water pump apparatus is provided having a plurality of modular components, which allows for construction of various configurations of the water pump apparatus depending on specific vehicle requirements. The water pump apparatus modular components include a pump housing with a fluid chamber formed therein, a bearing housing for attachment to the pump housing, and a thermostat housing for connecting to the bearing housing and the pump housing. A method for forming modular components for assembling a water pump apparatus for use in an internal combustion engine is also provided.

Abstract: A modular system for constructing a coolant core/cylinder head structure, is described. The system comprises a modular coolant core having an inlet and an outlet, a plurality of passageways within an interior space of the coolant core, the passageways fluidly connecting, which create a specific coolant flow pattern between the inlet and the outlet, wherein the coolant core has a single pattern geometry for assembling into the cylinder head core box. Use of the individual modular coolant cores permits construction of customized cylinder heads, which use the same tooling across multiple engine platforms, while providing more uniform coolant velocity and heat rejection from cylinder to cylinder and improved structure with more uniform clamping load between head bolts around the combustion chamber.

Abstract: A fuel injector clamp and method of clamping a fuel injector includes clamp members each including a central body with a concaved section and two horizontally offset passageways. Clamp members are oppositely oriented such that the concaved section forms a region adapted to engage a fuel injector. Offset passageways are aligned such that a top passageway of one member is aligned with a bottom passageway of the opposing member. A fastening mechanism is passed through a first pair of aligned passageways to form a hinge, allowing clamp members to pivot about the hinge so a fuel injector can be disposed between the concaved sections. Members are then pivoted towards each other to close the clamp assembly; a second fastening mechanism is passed through a second pair of aligned offset passageways to lock the injector into place.

Abstract: A mount (50) for mounting an exhaust gas component (30, 32, 16) in an exhaust pipe (34) or in a component housing includes a spring band (54) and a plurality of spring fingers (64). The spring band (54) is configured to contact and substantially pass around an outer surface (52) of the exhaust gas component (30, 32, 16). The plurality of spring fingers (64) extend from the spring band (54) generally axially with respect to the exhaust gas component (30, 32, 16) and generally radially from the spring band. The spring fingers (64) contact the exhaust gas component (30, 32, 16).

Abstract: An actuator is provided for operating a valve in an engine. The actuator includes a casing forming an actuation chamber for holding a working fluid and having a first cylinder portion with a first opening and a second cylinder portion with a second opening. A first plunger is held slidably at least partially within the first cylinder portion and exposed through the first opening, and a second plunger is held slidably at least partially within the second cylinder portion and exposed through the second opening. The first plunger is reciprocally movable by action of a rotating cam to displace working fluid within the actuation chamber. The second plunger reciprocally movable by pressure exerted on the second plunger by the working fluid and arranged to exert force on a valve.
