摘要： An internal combustion engine (11) includes an exhaust gas recirculation system and a two-stage charge air compression system which utilizes a turbocharger (14) with an exhaust gas turbine (15) and a compressor (18); a motor-driven air charge compressor (22) connected to an inlet (20) of the turbocharger compressor (18); a two-input proportioning gas control valve (35) having a first inlet (36) to the atmosphere, a second inlet (37) connected with an EGR conduit and an outlet (39) delivering a mixture of air and exhaust gas to the inlet of the motor-driven compressor (22); and a controller (40) for operating the two-input proportioning gas control valve utilizing an algorithm for controlling the gas control valve to provide an optimal mixture of recirculated exhaust gas and air. Such systems can include a bypass conduit (28) with a check valve between an inlet (21) and outlet (23) of the motor-driven charge air compressor, an EGR cooler (45), an EGR particulate filter or trap (29), and an intercooler (24) for the compressed charge air.

摘要： The invention relates to a method for controlling an electric booster (12) in an internal combustion engine comprising an exhaust gas turbocharger (18, 32) in such a way that the electric booster (12) is connected using as little power as possible. The connection of said electric booster (12) depends on the power balance, said electric booster only being activated when the instantaneously available compressor power of the exhaust gas turbocharger (18, 32) is insufficient to provide the necessary power.

摘要： The present invention relates to a method of operating an internal combustion engine including at least one cylinder and a piston slidable in the cylinder, the method comprising the steps of:
supplying pressurized air from an intake manifold to an air intake port of a chamber in the cylinder;
selectively operating an air intake valve to open the air intake port to allow pressurized air to flow between the chamber and the intake manifold substantially during a majority portion of a compression stroke of the piston; and
operably controlling a fuel supply system to inject fuel into the chamber after the intake valve is closed.摘要翻译： 本发明涉及一种操作内燃机的方法，所述内燃机包括至少一个汽缸和可在气缸中滑动的活塞，所述方法包括以下步骤：将加压空气从进气歧管提供给腔室的进气口 圆筒; 选择性地操作进气阀以打开所述进气口，以允许加压空气在所述活塞的压缩冲程的大部分期间基本上在所述室和所述进气歧管之间流动; 并且在所述进气门关闭之后，可操作地控制燃料供应系统以将燃料喷射到所述室中。

摘要： A device for handling and recovering of kinetic energy in a fluid is presented which basically features a bladed impeller (11). The impeller is operated by an electric engine (12) and acts as a centrifugal blower yielding energy to the air when the main engine is in a low boost phase; otherwise in case of excessive boost pressure, the impeller receives the moving fluid which will drive its rotation, reducing pressure and absorbing the energy to operate the electric engine (12) which will act as a reversible electric machine, thus generating electric power.
