Abstract: A power generation system has a power source and an aftertreatment system connected to the power source. The aftertreatment system is adapted to treat an exhaust of the power source. The aftertreatment system has a particulate filter that is dimensioned to be interchangeable with a muffler.

Abstract: An exhaust system in an internal combustion engine has an exhaust manifold, an exhaust flange is connected to the exhaust manifold, and a turbocharger is connected to the exhaust flange. The turbocharger has an exhaust inlet flange connected to the exhaust flange. The exhaust manifold has a first passage and a second passage, and the exhaust flange has a first exhaust port and a second exhaust port. The exhaust ports of the exhaust flange each have a generally triangular cross-sectional configuration.

Abstract: A fuel injector assembly for use in an electrically-controlled engine having a fuel injector and an electrical adapter. The fuel injector has a first set of electrical connectors and a second set of electrical connectors. The electrical adapter has a body, a first set of electrical receptacles, a second set of electrical receptacles, and a plug interface. The first set of electrical receptacles are electrically connectable with the first set of electrical connectors. The second set of electrical receptacles are electrically connectable with the second set of electrical connectors. The plug interface has a first set of electrical contacts electrically connected to the first set of electrical receptacles. The plug interface also has a second set of electrical contacts electrically connected to the second set of electrical receptacles.

Abstract: A cylinder head of an engine has a body, at least one recirculation chamber, and a flow control system. The body defines at least one orifice, and the recirculation chamber is in fluid communication with the at least one orifice. The flow control system has an inlet flow position and an outlet flow position. A method of operating an engine having at least one recirculation chamber and at least one combustion chamber containing a pressurized fluid includes transferring a portion of the pressurized fluid from the at least one combustion chamber to the at least one recirculation chamber when the pressurized fluid reaches a first predetermined pressure value. The method also includes transferring the portion of the pressurized fluid from the at least one recirculation chamber to the at least one combustion chamber when the pressurized fluid in the at least one combustion chamber reaches a second predetermined pressure value.

Abstract: An engine has a cylinder head having a first surface and a second surface spaced from the first surface. A valve is moveably connected to the cylinder head. A rocker arm is connected to the valve, and a rocker shaft having a first location spaced a maximum distance from the cylinder head is connected to the rocker arm. A support member has and an actuator fluid passage network. The actuator fluid passage network defines a volume. The support member is connected to the cylinder head and is positioned such that a majority of the volume of the actuator fluid passage network is between the first location of the rocker shaft and the second surface of the cylinder head.

Abstract: A reciprocating internal combustion engine used a crankshaft to develop rotating motion. A rotary pulse detonation engine can be adapted to rotate a shaft. A combustor portion of the rotary pulse detonation engine is spaced from an axis of the shaft a preestablished distance therebetween in a mass member. An intake portion and an exhaust portion of the combustor portion is positioned in a parameter of the mass member. A combustion portion of the combustor portion is interposed the intake portion and the exhaust portion. The combustion portion has a frustoconical first position which converges to form a deflagration wave and progresses into a detonation. The deflagration to detonation transition occurs in the transition region. A combustible fuel and air mixture is combusted in the combustor portion creating a high speed jet exiting the exhaust portion and rotating the shaft.

Abstract: During assembly, shipping and handling before a mechanically-actuated fuel injector is installed into an internal combustion engine, the fuel injector tappet often accidentally disconnects from the fuel injector body. This separation of the tappet from the fuel injector body is caused by a force placed upon the tappet by a biasing means, such as a spring, that pushes the tappet away from the injector body. The fuel injector of the present application solves this problem through the interaction of a retention clip, a retention opening in the fuel injector body, and a retention slot in the fuel injector tappet. The retention clip has a body and a protrusion. The retention clip body is contained within the fuel injector body, and the protrusion extends through the retention opening and into the retention slot. After it is assembled, the fuel injector of the present application remains connected during shipping and handling and permits easy installation into an internal combustion engine.

Abstract: A method and a system for treating an internal combustion engine exhaust gas using a hydrocarbons as fuel. The internal combustion engine exhaust gas contains particulates and toxic substances. Such particulates and toxic substances being liquid and gaseous hydrocarbons, carbon monoxide, and Nox. The system uses carbon dioxide to interact with the exhaust gas. The carbon dioxide is stored within a container at its triple state. The carbon dioxide and the exhaust gas are conducted through an emission exchanger. The exhaust gas is scrubbed or cleaned by the carbon dioxide and the hydrocarbons, carbon monoxide, Nox, and particulate emissions are carried away by a carbon dioxide gas stream. The cleaned exhaust gas can be discharged into the atmosphere. The carbon dioxide gas stream can be cleaned by passing the same through separator components which remove the pollutants therefrom.

Abstract: A piston insertion machine for inserting piston assemblies into respective cylinders of an internal combustion engine. The piston insertion machine eliminates the need for individually lifting and inserting the piston assemblies into the respective cylinders. The piston insertion machine includes a barrel assembly for holding the piston assembly. A first set of components pivot the piston barrel assembly (and thus the piston assembly) from an upright position to a horizontal position. Another component inserts the piston assembly into the cylinder of the engine block.

Abstract: Modern internal combustion engines produce high temperatures and pressures in the combustion chamber of the engine that place immense stresses on the engine's pistons. These temperatures and pressures can cause pistons to deform or wear and prematurely fail. One of the primary means of overcoming these detrimental effects on a piston is increasing the efficiency of heat rejection from the piston. One method of increasing the amount of heat drawn away from the piston is increasing the surface area of the inner surface of the piston crown so that a cooling medium, such as oil, can contact the inner surface and draw heat therefrom. Installing or forming an annular fin in the underside of the piston increases the surface area for oil to contact and permits precise targeting of piston locations from which heat is to be evacuated. Such annular fins can be quickly and easily installed or formed for use with any type of pistons, such as forged, cast, composite or mechanically joined pistons.
