摘要： An internal combustion engine operating generally in accordance with a thermodynamic cycle called the General Cycle, achieving maximum efficiency with limited pressure and temperature, and having an expansion ratio RE, a compression ratio RC and an Atkinson ratio A. The Atkinson ratio is in the range from 1.1 to 1.8, the expansion ratio is in the range from 22 to 50, and the compression ratio is in the range from 20 to 36. Given engine parameters, an optimum efficiency RE-RC pair can be determined. The engine may include a high ratio of stroke length to bore, or may be of an opposed piston construction.

摘要： An introduction pipe has a first communication pipe, which is branched from a first intake passage and is connected to a resonator box, and a second communication pipe, which is branched from a second intake passage and is connected to the first communication pipe. The length of the first communication pipe between the branch point at which the first communication pipe is branched from the first intake passage and the connection point at which the second communication pipe is connected to the first communication pipe is defined as a first length. The length of the second communication pipe between the branch point at which the second communication pipe is branched from the second intake passage and the connection point at which the second communication pipe is connected to the first communication pipe is defined as a second length. The first length is unequal to the second length.

摘要： A system having an engine is provided. The system includes a high pressure (HP) turbocharger and a low pressure (LP) turbocharger connected in series with each other. The system also includes a first valve assembly configured to selectively bypass at least a portion of the exhaust from the engine to the LP turbocharger. The system also includes a storage tank configured to store a pressurized fluid and configured to be in fluid communication with the HP turbocharger and the LP turbocharger. The system further includes a second valve assembly in fluid communication with the storage tank, the HP turbocharger and the LP turbocharger. The system also includes a controller operatively coupled to the first valve assembly and the second valve assembly. The controller is configured to selectively operate the first valve assembly and the second valve assembly based on a change in a load requirement on the engine.

摘要： To balance a “low-temperature scavenging effect” and a “high-temperature scavenging effect.” A scavenging system applicable to a leading-air type two-stroke air-cooled engine has a low-temperature scavenging passage and a high-temperature scavenging passage. The low-temperature scavenging passage has first and second passages and includes scavenging ports at upper end parts thereof. The high-temperature scavenging passage has first and second passages and includes scavenging ports at upper end parts thereof. An air is filled through a piston groove into the passages. The low-temperature scavenging passage has a relatively small capacity. The high-temperature scavenging passage has a relatively large capacity.

摘要： Systems and methods are provided for controlling a purging operation of a fuel vapor canister in a boosted engine. One method comprises purging stored fuel vapors from the fuel vapor canister to an inlet of the compressor via an ejector while bypassing a canister purge valve, the ejector being fluidically coupled to the fuel vapor canister by a distinct passage coupled upstream of the canister purge valve, where motive flow through the ejector may be regulated by a shut-off valve. The shut-off valve may be adjusted based on whether or not the engine is boosted.

摘要： The motorcycle includes: a supercharger that pressurizes intake air to supply the pressurized intake air to an engine; and an intake air tank forming an air intake chamber therein, which air intake chamber is provided at the downstream side of the supercharger with respect to an intake air flow direction and stores the intake air. The air intake chamber structure further includes an intake pipe formed as a separate body from the intake air tank and mounted on the intake air tank. The intake pipe serves as an inlet of the air intake chamber and projects inward of the air intake chamber. A projecting end portion of the intake pipe has a passage area that increases toward the downstream side in the intake air flow direction.

摘要： Methods and systems are provided for enhancing purge flow when applying shallow intake manifold vacuum. An alternate purge route that circumvents the more restrictive canister purge valve and directs purge vapors through a branched path via a less restrictive mechanical purge valve is used during low intake manifold vacuum conditions. By enabling higher purge flow rates when manifold vacuum is lower, a more complete canister cleaning is ensured.

摘要： The present invention uses the exhaust gas of an internal combustion reciprocating engine to drive a turbine. The turbine is position around the cylinder. The turbine is connected to systems that will use the energy to improve the total system efficiency. One such system would be connected to a compressor to create the force induction required for two-stroke engines.
