| 20100031917 | INTERNAL COMBUSTION ENGINE - There is provided an internal combustion engine in which the inside thereof is uniformly cooled. In an engine serving as the internal combustion engine, a piston reciprocates within a bore provided in a cylinder block, and a connecting rod coupled to the piston transmits motive power to a crankshaft. The internal combustion engine includes a rear-side oil jet through which oil is injected from the connecting rod side of the piston to a skirt inner region and a skirt outer region of the piston. | 02-11-2010 |
| 20110197847 | CONNECTING ROD-PISTON GROUP - The invention relates to mechanical engineering, in particular to units for piston machines, primarily internal combustion engines. A connecting rod and piston assembly comprises a piston, which is accommodated in a cylinder and is provided with a head and an insert, a piston pin, and a connecting rod with top and bottom heads and a bar. The insert is in the form of a hollow, box-like stiffening rib that transmits reactive load from the connecting rod to a housing via contact surfaces. The top head and a part of the connecting rod bar are accommodated in the box cavity, and a hole for the piston pin is provided in the side walls of the insert box. The head is connected to the insert with the aid of a hinged joint so that the head can self-center along the cylinder surface by moving in all directions with respect to the insert on a plane that intersects the longitudinal axis of the cylinder. The housing is provided with mating contact surfaces which interact with the contact surfaces of the insert and which are located on separate supporting elements secured on the housing. The technical result consists in increasing the performance, reliability and service life of machines which use the described assembly and in achieving high specific mass and dimensional parameters of such machines. | 08-18-2011 |
| 20110203547 | PISTON AND CONNECTING ROD ASSEMBLY HAVING IMPROVED COOLING CHARACTERISTICS - A piston and connecting rod assembly wherein the piston includes an inner cooling gallery defined in the body thereof beneath the crown of the piston, an outer cooling gallery defined between the skirt of the piston and the body and beneath the crown. A pin bore is formed in the body. A connecting rod is adapted to interconnect the piston and crankshaft where the connecting rod has at least one end with a bore extending therethrough and adapted to be aligned with the pin bore of the piston. At least one end of the connecting rod is in fluid communication with the inner cooling gallery of the piston and includes a reservoir formed on the end of the connecting rod which is adapted to collect coolant therein. | 08-25-2011 |
| 20140014060 | RECIPROCATING PISTON FOR A RECIPROCATING PISTON ENGINE AND RECIPROCATING PISTON ENGINE, AND CYLINDER OF A RECIPROCATING PISTON ENGINE - The invention relates to a reciprocating piston composed of ceramic material for a reciprocating-piston engine with crank drive, wherein the reciprocating piston is rigidly screwed to a piston rod by a screw, wherein between the reciprocating piston and the piston rod there is braced at least one disc composed of metallic material, wherein the screw is composed of a metallic material, wherein the coefficient of thermal expansion α | 01-16-2014 |
| 20140251256 | Double-Reed Exhaust Valve Engine - An engine based on a reciprocating piston engine that extracts work from pressurized working fluid. The engine includes a double reed outlet valve for controlling the flow of low-pressure working fluid out of the engine. The double reed provides a stronger force resisting closure of the outlet valve than the force tending to open the outlet valve. The double reed valve enables engine operation at relatively higher torque and lower efficiency at low speed, with lower torque, but higher efficiency at high speed. | 09-11-2014 |
| 20160123224 | SPRING LOADED PISTONS - Embodiments include a spring loaded piston in an internal combustion engine. In certain embodiments, the internal combustion engine may include a two stroke, one cylinder piston engine having first springs connecting between a piston and a cylinder head and second springs connecting between the piston and the base of the piston cylinder. The first springs are relatively compressed when the crankshaft is at top dead center while the second springs are relatively relaxed when the crankshaft is at top dead center and vice versa at when the crankshaft is at bottom dead center. During the power/intake stroke, some of the fuel's energy is delivered to the crankshaft and some is used to compress the second springs. The stored energy in the second springs is delivered to the crankshaft during the exhaust/compression stroke while the second springs return to their relatively relaxed condition and vice versa for the first springs. | 05-05-2016 |
