摘要： It is an object of the invention to enhance the possibility of realizing a required torque in a supercharging region where scavenging occurs in a control apparatus for a supercharged engine. In order to achieve this object, the control apparatus for the supercharged engine according to the invention determines an operation amount of an intake valve driving device from a target in-cylinder air amount that is calculated from a required torque, and determines an operation amount of a throttle from a target intake valve passing air amount that is obtained by adding an amount of air blowing through an interior of a cylinder to the target in-cylinder air amount.

摘要： Systems, apparatus, and methods are disclosed that include an internal combustion engine having a plurality of cylinders and at least one camshaft for opening at least one valve associated with the at least one cylinder. The camshaft includes a cam with a cam lobe defining a cam lobe profile having a base circle portion on a base circle of the cam lobe, a main cam lobe portion, and a low lift dwell portion that extends a constant height from the base circle along a substantial portion of the base circle to increase valve opening overlap and cylinder scavenging.

摘要： To improve the effect of preventing contamination of an element in an air cleaner. An air cleaner includes a first inlet (60) through which air is fed to an intake system air passage and a second inlet (62) through which air is fed to an intake system air-fuel mixture passage. An extended passage (72) leads to the second inlet (62), for example. A passage forming member (70, 204) forming the extended passage (72) is shaped to surround a periphery of the first inlet (60). The passage forming member (70, 204) forms a blown-back fuel diffusion preventing region (74) leading to the first inlet (60).

摘要： A stratified scavenging two-stroke engine includes a first scavenging passage that extends from a first scavenging intake that opens to the inside of the crankcase to a scavenging port that opens to the inside of a cylinder, and a second scavenging passage that branches from the first scavenging passage and extends to a second scavenging intake that opens to the inside of the crankcase. An air passage is provided to supply air for pre-scavenging into the first scavenging passage at a position closer to the first scavenging intake than a position at which the second scavenging passage branches from the first scavenging passage. A first check valve inhibits a flow of air from the first scavenging passage during an upward stroke of the piston, and a second check valve inhibits a flow of air and a gaseous mixture from the first scavenging passage during a downward stroke of the piston.

摘要： A controller for an internal combustion engine is provided. The engine includes a compressor, a three way catalyst, a canister, an evaporated fuel passage, an ejector, and a purge control valve. The controller includes an ECU. The ECU is configured to decrease an opening degree of the purge control valve in response to an increase in pressure on the downstream side of the compressor in a lean supercharging range. The is a range in which an operation air-fuel ratio of the internal combustion engine is leaner than a theoretical air-fuel ratio of the internal combustion engine, and in which the pressure on the downstream side of the compressor is higher than pressure on the upstream side of the compressor.

摘要： A system and methods are described for a turbocharged engine, comprising powering the engine using a first operating cylinder, supplementing the power using a second switchable cylinder, deactivating the second switchable cylinder responsive to a load below a first threshold, and closing a first shut-off valve downstream of a compressor during the partial deactivation to prevent a first turbocharger from imparting a delivery action into a second compressor during the partial deactivation. Embodiments are further described wherein a bypass line in a second exhaust line further serves as a short-circuit line to prevent the second compressor from imparting a delivery action against the closed first shut-off valve. A variable valve timing is then included to further optimize the combustion process during the partial deactivation.

摘要： A true two-stroke (power and exhaust) internal combustion piston engine combining direct injection of all combustion and working fluid elements with exhaust valve(s) that open early during the power stroke if cylinder pressure falls below exhaust manifold pressure, will operate efficiently from power levels produced by conventional four-stroke engines of a fraction of the displacement of the two-stroke engine to power levels attainable by conventional four-stroke engines of twice the two-stroke engine displacement. No additional external systems will be required to enhance performance or control emissions, as all such enhancements are equivalent to control of the combustion and working fluid components. The magnitude of the combustion charge determines the power, and the makeup of the combustion components determine exhaust emissions. Any implementation of the true two-stroke engine will have the further advantages of requiring only half the cylinders (space and weight) and an equivalent reduction in required support systems. No intake valve train, no intake filter or manifolds, no catalytic converter or exhaust gas recirculation will be required. Some implementations may eliminate other support systems entirely (starter, cooling, exhaust valve train, etc.)
摘要翻译：一个真正的二冲程（动力和排气）内燃活塞式发动机将所有燃烧和工作流体元件直接喷射在排气阀上，排气阀在动力冲程期间早期打开，如果气缸压力低于排气歧管压力，将有效地从传统的四冲程发动机产生的功率水平是二冲程发动机排量的一部分，达到二冲程发动机排量的传统四冲程发动机所能达到的功率水平。不需要额外的外部系统来提高性能或控制排放，因为所有这些增强功能都等同于对燃烧和工作流体组件的控制。燃烧费用的大小决定了功率，并且燃烧部件的组成决定了废气排放。真正的二冲程发动机的任何实施将具有仅需要一半的气缸（空间和重量）和所需支撑系统的等效减少的进一步的优点。不需要进气阀系，无进气过滤器或歧管，不需要催化转化器或废气再循环。一些实施方式可以完全消除其他支持系统（启动器，冷却，排气阀列等）
