A method of modifying the oil cooling system of a diesel engine an engine oil supply outlet located in a horizontal plan includes the steps of removing the original equipment liquid-to-liquid heat exchanger and installing a manifold having an oil outlet port directed to a remote oil cooler and a bypass water passage providing an un-branched flow of water, whereby the flow of oil is directed to a remote oil cooler and the entirety of the flow of water in the bypass water passage is discharged back to the water cooling system of the engine without passing through an oil cooling or water cooling heat exchanger.

A mass air flow measurement apparatus for an internal combustion engine includes: a plurality of pressure sensors disposed at different locations along an air intake path of the internal combustion engine, each pressure sensor adapted to sense a pressure of air flowing into the internal combustion engine and output an electrical signal as a pressure signal corresponding to the sensed air pressure; a carburetor having a plurality of booster venturis, the carburetor rendered permanently inoperable to mix fuel with air flowing in the air intake path, a body of the carburetor configured to accept one or more of the plurality of pressure sensors for each of the plurality of booster venturis; and a calculation section that receives the pressure signals and generates a mass air flow signal as an output signal to an engine management system to control an electronic fuel injection system based on the received pressure signals.

Combustion equipment for use in a gas turbine engine is provided. The combustion equipment includes an inner and outer case, wherein the outer case encloses the inner case creating a cavity located between the two cases. The combustion equipment also has a fuel delivery device for delivering fuel into a combustion region within the inner case, wherein the fuel delivery device passes through a hole in the outer case and a corresponding hole in the inner case. The combustion equipment also includes a seal assembly to prevent the leaking of pressurized gas into the cavity located between the outer and inner cases via the hole through which fuel delivery device passes. The seal assembly includes a flexible sleeve that extends around the fuel delivery device and interconnects the inner case with the outer case, permitting relative movement of the inner and outer cases when the combustion equipment is in use.

A tool for installing a retrofit bearing having a length that extends beyond the original location of a tapered sleeve used to secure an original bearing and a method of performing the installation provide a reliable way to replace an engine bearing that supports and extends within a shaft end. The tool includes a flange with holes matching the engine block, a body coupled to the flange for accepting the captive portion of the replacement bearing, and a tapered sleeve disposed within the tool body for compressing a wire lock engaged with a mating channel of the replacement bearing when the captive portion is in the tool. The tapered sleeve has a diameter that mates with an inside diameter of an end of the engine shaft, so that the wire lock remains compressed until it engages with the channel provided in the engine shaft for the original snap ring.

Remanufacturing a used cylinder liner includes receiving a used cylinder liner having a fillet relieved of residual compressive stress via service in an engine, and compressing a material substrate of the cylinder liner forming a fatigue sensitive fillet, such that a non-uniform profile of the fillet is reshaped via plastic deformation of the material substrate. Residual compressive stress is restored to the fillet at least in part via the plastic deformation. A mask and used cylinder liner assembly for processing the used cylinder liner during remanufacturing is also disclosed.

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.

A mass-airflow measurement conversion apparatus for internal combustion engine carburetors includes a plurality of pressure sensors disposed at different location along an air intake path of an internal combustion engine, each sensor adapted to sense a pressure of air flowing into the internal combustion engine and output an electrical signal as a pressure signal corresponding to the sensed air pressure; and a calculation section that receives the pressure signals and generates a mass air flow signal as an output signal based on the received pressure signals.

An engine piston wrist pin installation tool, kit and method provide the ability to install a piston in an engine block while the corresponding piston rod is assembled to the crankshaft. The wrist pin aperture is first aligned with an access hole provided on the engine block, which may be performed by using a tapered alignment tool provided in the tool kit. A mounting flange configured for bolting to preformed holes in the engine block is first attached over the access hole, the alignment performed, and a tool including a cylindrical sheath that holds a wrist pin clip compressed and a rod that holds the wrist pin and clip is slid through a locking collar of the flange and secured in place. The rod is then pressed through the sheath to extend the wrist pin and wrist pin clip into the piston until the wrist pin clip snaps into place.

A combustor for use in a gas turbine engine and methods for assembling the same are disclosed. The combustor includes an outer case and a combustion liner. The combustion liner is arranged radially inward of the outer case. The combustion liner is arranged to define an annular combustion chamber.

A guide rod, which has a diameter expandable tip end portion and restricts the oscillation of a connecting rod and a piston, is inserted into a cylinder bore via an opening adjacent to a crank chamber of the cylinder bore, and the piston is inserted into the cylinder bore via a cylinder head mounting side opening with the connecting rod positioned at a leading end. The diameter of the tip end portion of the guide rod is increased in a hole of a semi-circular arc-shaped end portion positioned at tip end of the connecting rod in the insertion direction, and thus the connecting rod is engaged with the guide rod. The guide rod moves and the connecting rod is pulled into the cylinder bore until the semi-circular arc-shaped end portion of the connecting rod sits on a crankpin of a crankshaft.
