Abstract: A strap for securing an exhaust treatment device is disclosed. The strap may have a coupler on a first end and a loop on a second end. The loop may include an inner portion, a curved portion, and an outer portion of the strap. The outer portion of the strap may be secured to the inner portion of the strap at a point of securement to form the loop. The outer portion may form an angle with respect to the inner portion that is no greater than about 10 degrees as the outer portion diverges from abutting the inner portion.

Abstract: A thermostat assembly for a combustion engine having at least one cylinder is disclosed. The assembly has a cylinder head configured to cap off the at least one cylinder, the cylinder head having a recess fluidly connected to a coolant passage of the combustion engine. The assembly also has a thermostat located completely within the recess.

Abstract: An exhaust stack is disclosed for protecting exhaust system components from liquid entering an exhaust stack discharge port. The exhaust stack includes a first section defining a first flow passage extending along a first longitudinal axis and a second section having an open end and defining a second flow passage extending along a second longitudinal axis.

Abstract: An engine exhaust aftertreatment system including a bend routing an exhaust flow in a curved direction to a straight part. A nozzle is mounted in the bend to introduce a spray of a fluid with a axis of symmetry into the exhaust flow. The axis of symmetry intersects the exhaust flow traveling in the curved direction at a intersection angle of less than 50 degrees.

Abstract: An exhaust system for a power system contained in an engine compartment. The exhaust system includes a mount for two or more exhaust treatment devices and an enclosure surrounding the two or more exhaust treatment devices. The enclosure defines a space with a higher temperature than a space defined by the engine compartment during steady state operation of the power system. At least one electronic or fluid device is coupled to the enclosure or mount and located on an exterior of the enclosure.

Abstract: A damper assembly including an input member, an output member, and a transfer assembly is disclosed. The input member is configured to receive a torsional input. The output member is configured to provide a torsional output. The transfer assembly is coupled between the input member and the output member and includes a ring, a first guide, a second guide, a first spring, and a second spring. The ring defines a first linear slide path that has a first end and a second end, and a second linear slide path that has a third end and a fourth end. The first guide is slideable within the first linear slide path and coupled to the input member. The second guide is slideable within the second linear slide path and coupled to the input member. The first spring is positioned between the first guide and the second end of the first linear slide path. The second spring is positioned between the second guide and the fourth end of the second linear slide path.

Abstract: A thermostat assembly for a combustion engine having at least one cylinder is disclosed. The assembly has a cylinder head configured to cap off the at least one cylinder, the cylinder head having a recess fluidly connected to a coolant passage of the combustion engine. The assembly also has a thermostat located completely within the recess.

Abstract: A fluid system for an engine is disclosed. The fluid system has a manifold with a plurality ports, and a retention device configured to constrain the manifold relative to the engine in only a single translational direction. The fluid system also has a plurality of tubes configured to communicate fluid from the ports with the engine and to constrain the manifold in the remaining translational directions.

Abstract: An internal combustion engine, particularly suitable for use in a motor vehicle, is provided with a combustion air supply, an exhaust manifold, and a bypass venturi assembly. The bypass venturi assembly includes a housing having an outlet, a combustion air inlet connected and in communication with the combustion air supply, and an exhaust gas inlet connected and in communication with the exhaust manifold. A venturi nozzle is positioned in communication with the combustion air inlet. The venturi nozzle defines a bypass venturi section therein. The venturi nozzle and the housing define an exhaust gas venturi section therebetween terminating at an induction area. The venturi nozzle has a plurality of through holes in communication with a downstream portion of the exhaust gas venturi section. The exhaust gas inlet terminates at the induction area. A bypass valve is positioned to open and close the bypass venturi section.

Abstract: A vibration isolation or noise attenuation and fluid sealing system, for use in connection with internal combustion engine components. For example, for use in the mounting of a valve cover or rocker arm cover upon a cylinder block or cylinder head, or for the mounting of an oil pan cover upon an oil pan housing. The system has an isolation medium or member mechanically and/or chemically bonded to a peripheral flange portion of the cover member. A sealing flange member is chemically and/or mechanically bonded to the isolation member or medium. The three components being a one-piece unitary cover assembly. The fluid leakage along the interfaces defined between the three components is effectively eliminated. The one-piece assembly is secured to the cylinder block or head, or the oil pan housing, by shoulder bolt fasteners. The fasteners exert compressive forces upon the isolation member so as to vary the stiffness and frequency characteristics thereof.
