Turbomachine component having an internal cavity reactivity neutralizer and method of forming the same
A turbomachine component includes a body having an exterior surface and an interior surface, an internal cavity defined by the interior surface, and a reactivity neutralizing member arranged within the internal cavity. The reactivity neutralizing member is configured and disposed to neutralize turbomachine combustion products on the interior surface of the body.
Vane insertable tie rods with keyed connections
A gas turbine engine includes a combustor, a first turbine section in fluid communication with the combustor, a second turbine section in fluid communication with the first turbine section, and a mid-turbine frame located axially between the first turbine section and the second turbine section. The mid-turbine frame includes a first frame case, a second frame case, a vane positioned between the first frame case and the second frame case, and a spoke extending through the vane and connecting the first frame case to the second frame case. The spoke includes a tie rod having a first end connected to the first frame case at a keyed connection.
Method and apparatus for winding a return spring with a two piece rotor for a cam phaser
A camshaft phaser, including: a drive sprocket; a stator; a rotor at least partially rotatable with the stator; a rotor extension fixedly connected to the rotor, having a slot at at least one outer circumferential position; a spring for biasing the rotor relative to the stator, having a first and a second end, the first end secured in the slot in the rotor extension and the second end secured on the stator.
Layered diaphragm
In at least some implementations, a carburetor has a metering system that controls fuel flow from a fuel source to an air-fuel passage. The metering system includes a metering diaphragm sealed to a body of the carburetor to at least partly define a metering chamber between the metering diaphragm and the body, and the metering diaphragm has a continuous layer and a discontinuous layer. The continuous layer is responsive to fluid pressure within the metering chamber and moves against the discontinuous layer to open a metering valve to allow fuel flow from the fuel source and into the metering chamber when said fluid pressure is below a reference pressure.
SCR-module
Reciprocating-piston internal combustion engines having different power outputs are to be equipped simply, reliably and inexpensively with a device for the selective catalytic reduction of the exhaust gases having an SCR module for a reciprocating-piston internal combustion engine, comprising a housing and/or a frame, an exhaust-gas section which delimits a flow duct for guiding through exhaust gas, having an inlet opening for introducing the exhaust gas and an outlet opening for discharging the exhaust gas, an SCR catalytic converter which is arranged inside the flow duct, at least one injection element for adding a reducing agent, for example ammonia or a urea solution, to the exhaust gas which is guided through the flow duct. This problem is solved by virtue of the fact that the SCR module comprises at least one delivery device (13) for feeding the reducing agent to the injection element at a predetermined pressure.
Method of modifying engine oil cooling system
A method of modifying the oil cooling system of a diesel engine includes the steps of removing the original equipment liquid-to-liquid heat exchanger and installing a manifold having a configuration adapted to match the mounting configuration of the oil passages of the original equipment liquid-to-liquid heat exchanger. The manifold has an oil outlet port directed to a remotely mounted oil cooler. The manifold also has a water passage having a configuration that is adapted to match the mounting configuration of the water passages of the original equipment liquid-to-liquid heat exchanger. The water passage causes the entirety of the flow of water to be discharged back to the water cooling system of the engine where it is circulated by the water pump through the water cooling passages in the engine.
Cable-operated actuating device for a motor vehicle
The present invention relates to a cable-operated actuating device for a motor vehicle, in particular for a transmission, comprising: an actuating means having a recess for inserting a coupling connector of a cable control, a blocking means which is radially displaceable in the recess and in a radially outer position permits an axial displacing of the coupling connector in the recess and in a radially inner position axially fixes the coupling connector against an inserting direction in a positively connected and/or frictionally connected manner, a housing, which receives a connecting point between the coupling connector and the recess, and an actuating means for radially displacing the blocking means, which can be actuated outside the housing.
Industrial gas turbine exhaust system with modular struts and collars
An integrated single-piece exhaust system (SPEX) with modular construction that facilitates design changes for enhanced aerodynamics, structural integrity or serviceability. The SPEX defines splined or curved exhaust path surfaces, such as a series of cylindrical and frusto-conical sections that mimic curves. The constructed sections may include: (i) a tail cone assembly fabricated from conical sections that taper downstream to a reduced diameter; or (ii) an area-ruled cross section axially aligned with one or more rows of turbine struts; or both features. Modular inner and outer diameter inlet lips enhance transitional flow between the last row blades and the SPEX, as well as enhance structural integrity. Modular strut collars have large radius profiles between the SPEX annular inner diameter and outer diameter flow surfaces, for enhanced airflow and constant thickness walls for uniform heat transfer and thermal expansion. Scalloped mounting flanges enhance structural integrity and longevity.
Engine cover integrated captive fastener
An engine cover assembly having an integrally attached captive fastener or part-in-assembly fastener for attachment to an engine is disclosed. The engine cover assembly includes an engine cover having a fastener aperture formed in a recessed area thereof and a captive fastener assembly integrally attached to the cover. The captive fastener assembly includes an elongated fastener having a head or shoulder, a load limiting spacer disposed next to the shoulder of the elongated fastener, and a load limiter positioned next to the load limiting spacer. The load limiter has shoulders formed at both ends. The elongated fastener has a threaded end for attachment to a threaded insert positioned in the engine. Insulators are attached to the load limiting spacer and are positioned to either side of an area of the engine cover adjacent the fastener aperture, thus capturing the engine cover between the elongated fastener head and the load limiter.
Laser welding method and engine cooling structure
A cylinder block (10) includes an inter-bore flow passage (14) between adjacent bores (12). Each inter-bore flow passage (14) is formed by closing an opening-side groove portion (15) continuous from a cylinder block deck face and a bottom-side groove portion (16) with the use of a lid member (20) made of copper, and the lid member (20 is laser-welded to a groove wall face of the opening-side groove portion (15). Before the laser-welding, the lid member (20) has recesses (26) that are interspersed in a direction, in which a laser beam travels, at any one of connected portions at which the lid member (20 is connected to the groove wall face of the opening-side groove portion (15).
