摘要： An improved lubrication system and method for the normally contacting and abutting piston pin and connecting rod journal bearing surfaces of an internal combustion engine that includes an inertia pump in a connecting rod. The inertia pump reacts to the movement of the connecting rod and conveys a predetermined measure of lubricating oil at a high enough pressure to overcome the forces which cause the surfaces to normally maintain contact. By separating the normally contacting surfaces of the pin and the connecting rod journal, the surfaces become lubricated. Several embodiments of inertia pumps provide variations in implementing the invention.

摘要： A fuel injector system for raising fuel to its supercritical state and injecting the supercritical-state fuel to the combustion chamber of an internal combustion engine is disclosed. A plurality of injector embodiments provides alternative ways to heat the pressurized fuel to its supercritical state. Injection of supercritical fuel into the combustion chamber is known to improve fuel entrainment and reducing ignition delay to thereby increase combustion rate, which leads to an increase in fuel efficiency. According to some embodiments, the system provides for preventing coking that may otherwise occur in an exhaust gas heat exchanger used for preheating the high pressure fuel. In other embodiments, engine cold start assistance is provided by storing pressurized, heated fuel in an insulated container.

摘要： A combustion chamber in an opposed-piston, internal-combustion engine is disclosed in which the pistons tops are designed so that when they approach each other, they induce a tumble flow in one or two hemispherical spaces defined in the piston tops. The combustion chamber further includes injectors side mounted in the cylinder wall. In one embodiment, the tumble flows in the two hemispheres are in the same direction and in another embodiment, in opposite directions. In yet another embodiment, there is only one injector and one hemisphere in which a tumble flow is induced.

摘要： An improved oil and gas seal assembly for an internal combustion engine that includes a scraper ring retained within an annular containment groove that, in several embodiments, is formed in the side wall of the cylinder and sized to allow the scraper ring to be fitted therein. The depth of the annular containment groove is sufficient to allow the scraper ring to be expanded during assembly with the piston and during engine operation when the assembly is exposed to vibration and heat variations. A resilient element surrounds the scraper ring within the annular containment groove in order to apply inward forces to the scraper ring and keep it in contact with the movable piston skirt side wall, and also in contact with at least one wall of the groove to prevent an alternative migration path for oil or combustion gases.

摘要： By providing an electrically-controlled turbocharger (ECT) on a compression-ignition (CI) engine, the engine can be provided a desired lambda and a desired EGR fraction over the range of operating conditions. When lambda in the exhaust is leaner than the desired lambda, electrical energy to the electric motor of the ECT is reduced to bring actual lambda to desired lambda. Analogously, when lambda in the exhaust is richer than the desired lambda, electrical energy to the ECT is increased.

摘要： Reciprocating motion can be converted to rotary motion through a crankshaft and a connecting rod. In a connecting rod that is primarily in tension, two opposing connecting rods can be coupled to a single journal. Two bearing caps are placed over the journal, the bearing caps having fingers that extend away from the bearing cap with the fingers of the two bearing caps being enmeshed. Fingers of each bearing cap are coupled to the connecting rods. The resulting joint is compact and lighter weight with a shorter journal than prior joints.
