摘要： Multiple intake valves operatively associated in a common combustion chamber are advantageous in that the design achieves high output for an internal combustion engine. The subject modified cylinder head utilizes the advantages available in a multiple intake valve system, but further enhances the design by reducing heat rejection. In the subject modified cylinder head, three intake valves (38,40,42) having corresponding intake valve ports (26,28,30) and one exhaust valve (68) having an exhaust valve port (66) are operatively associated in a common combustion chamber. A reduction in heat rejection is achieved through a relationship between the cross-sectional areas of the intake and exhaust valve ports (26,28,30,66). The intake valve ports (26,28,30) are constructed so that their cross-sectional area is larger than about 69% of the combined cross-sectional area of the intake and the exhaust ports (26,28,30,66).

摘要： An engine includes an engine casing and a first piston configured to reciprocate relative to the engine casing. The first piston has a wall that defines a substantially cylindrical chamber. One or more second pistons are configured to reciprocate inside the substantially cylindrical chamber. A combustion chamber intake port and a combustion chamber exhaust port extend through the wall. A shutter is outside the wall and is movable between a first position substantially blocking fluid flow through the combustion chamber exhaust port but not blocking fluid flow through the combustion chamber intake port and a second position substantially blocking fluid flow through the combustion chamber intake port but not blocking flow through the combustion chamber exhaust port. An actuator causes the shutter to move between the first position and the second position in response to the first piston reciprocating relative to the engine casing.

摘要： An engine includes a first piston with surfaces that define a substantially cylindrical chamber inside the first piston and a passage into the substantially cylindrical chamber. One or more second pistons are arranged to reciprocate inside the substantially cylindrical chamber and to define, in cooperation with the substantially cylindrical chamber, a combustion chamber. A fuel injector extends at least partially through the passage in the first piston to inject fuel into the combustion chamber. The first piston is arranged to move in a reciprocating manner relative to the fuel injector.

摘要： Internal combustion engines have been developed having regeneration mechanisms for increasing efficiency and reducing emissions. Previous regeneration mechanisms have been complicated and costly. The present invention provides a simple regeneration member which is attached within a piston assembly. Thus the apparatus for attaching the regeneration member within the internal combustion engine greatly reduces the cost of the engine.

摘要： An exhaust gas recirculation system for use with an internal combustion engine comprising a heat exchanger, a first turbocharger, and a generator. The first turbocharger provides compressed fresh air to an intake manifold. The heat exchanger cools the exhaust gas for recirculation into the intake manifold. The generator provides turbocharger control by imparting stored energy back into the turbocharger. Turbocharger control allows the exhaust gas recirculation system to operate more efficiently and over a wide range of operating conditions.

摘要： Most internal combustion engines may be optimized for either power or efficiency. A dual mode internal combustion engine may operate in either a power mode or an efficient mode. The dual mode internal combustion engine has two four-cycle combustion chambers and a two-cycle compression/expansion chamber. The valve system is set up to introduce a fluid charge into the compression/expansion cylinder during the power mode. The fluid charge is compressed in the compression/expansion chamber and one of the combustion chambers. During the efficiency mode, the fluid charge is expanded first in one of the combustion chambers and further expanded in the compression/expansion chamber.
