Abstract:
An internal combustion engine comprises a housing including a combustion cylinder, a piston including a piston skirt reciprocally disposed within the combustion cylinder and having a piston pin, the piston skirt defining a bottom surface and having a lubrication passage therein, the lubrication passage having an inlet in the bottom surface of the piston skirt and an outlet adjacent the piston pin, a connecting rod including an eye pivotally disposed about the piston pin, the eye having a lubrication bore oriented to provide at least intermittent fluid communication between the piston pin and the outlet of the lubrication passage, and a lubrication applicator adapted to apply lubricant to the inlet of the lubrication passage.
Abstract:
An internal combustion engine includes a cylinder block with a cylinder bore. A cylinder head is attached to the cylinder block and covers the cylinder bore. A cylinder liner within the cylinder bore has a distal end, an inside diameter, and an annular recess extending radially outwardly from the inside diameter at the distal end. A piston is reciprocally disposed within the cylinder liner. An annular scraping ring positioned in the annular recess has an inside diameter which is smaller than the inside diameter of the cylinder liner and is configured to scrape deposits from the piston. The scraping ring extends axially beyond the distal end of the cylinder liner. An annular sealing ring is separate from, located by and positioned radially outwardly adjacent to the scraping ring. The sealing ring directly engages and seals between the cylinder head and the distal end of the cylinder liner.
Abstract:
A fluid leak limiter for a high-pressure fuel injection system is disclosed. The fluid leak limiter may have a body at least partially defining a central bore with a fluid inlet and a fluid outlet, and a sleeve piston. The fluid leak limiter may also have a spring located to bias the sleeve piston toward a first flow-blocking position. The sleeve piston may be movable by a first pressure differential between the fluid inlet and the fluid outlet against the bias of the spring toward a flow-passing position at which fluid from the fluid inlet is allowed to flow to the fluid outlet. The sleeve piston may also be movable by a second pressure differential between the fluid inlet and the fluid outlet against the bias of the spring toward a second flow-blocking position at which fluid from the fluid inlet is inhibited from flowing to the fluid outlet.
Abstract:
An exhaust manifold assembly for use with an internal combustion engine includes a segmented exhaust manifold with a first segment and a second segment. The first segment has an inlet end for connection with the internal combustion engine and an outlet end. The second segment has an inlet end for connection with the internal combustion engine and an additional inlet end connected with the outlet end of the first segment. An exhaust connector is connected between the outlet end of the first segment and the additional inlet end of the second segment. The exhaust connector includes an inner tubular element, an outer tubular element and a bellows. The outer tubular element is positioned radially around the inner tubular element. The bellows engages the inner tubular element and biases the inner tubular element against the first segment or the second segment. The bellows also engages the outer tubular element and biases the outer tubular element against the other of the first segment or the second segment. The exhaust connector is held in place between the segments using only compressive loading therebetween.
Abstract:
A cylinder liner assembly for an internal combustion engine is disclosed. The assembly includes a cylinder head, a cylinder block defining a top deck surface and a cylinder bore extending from the top deck surface, and a cylinder liner mounted in the cylinder bore. The cylinder liner includes a flanged end extending over the top deck surface of the cylinder block. A hardened annular deck plate is provided about the cylinder bore between the flanged end of the cylinder liner and the cylinder block to prevent cracking of the cylinder block when the flanged end is clamped between the cylinder head and the cylinder block. The hardened annular deck plate has a hardness in the range of about 25 to about 60 on a Rockwell "C" scale, and preferably about 50 on a Rockwell "C" scale.

Abstract:
An internal combustion engine includes a cylinder block with a cylinder bore. A cylinder liner within the cylinder bore has a distal end with an outside diameter. A cooling ring has a first inside diameter, a larger second inside diameter and a plurality of radial coolant passages. The first inside diameter is positioned closely adjacent to the outside diameter at the distal end of the cylinder liner. The second inside diameter is radially spaced apart from and defines an annular coolant channel with the outside diameter of the cylinder liner. The radial coolant passages are in fluid communication with the annular coolant channel.
Abstract:
A cylinder liner for an internal combustion engine is externally threaded at a first end portion. An annular groove having a threaded first side surface is disposed in a cylinder head. The cylinder liner is screwthreadably engaged with threaded annular groove, forcibly engaged with an end surface of the annular groove, and sealed by side thread loading. A seal member and ring disposed about the cylinder liner and in a coolant passage isolates the threads from coolant fluid and optimizes cylinder liner cooling. A minimum crevice volume is provided between the annular groove and the cylinder liner.
