摘要： An intake system for an internal combustion engine in which the inflow characteristic of a mixture of gas is varied by a partition wall provided replaceably in an intake port opening, whereby the output characteristic of the internal combustion engine is regulated to a desired condition, and a vehicle having appropriate operating characteristics is provided. A replaceable partition wall A is mounted in an intake port opening 1a of an internal combustion engine. The partition wall A is composed of a plate P that differs in length as compared to other plates. The plate P is inserted into an upper-lower pair of grooves provided in the intake port opening 1a, whereby the plate P is replaceably mounted, and the inflow characteristic of a mixture of gas sucked in through the intake port opening 1a is varied by replacement of the plate P thus mounted, whereby the output characteristic of the internal combustion engine is regulated to a desired condition.

摘要： To provide a two-cycle internal combustion engine including a combustion chamber; a chamber portion adjacent to the combustion chamber; a communication passage between the combustion chamber and the chamber portion; and a control valve, provided in the communication passage, for opening the communication passage nearly at a point of time when a scavenging opening is closed and closing the communication passage at a mid point in the compression stroke, wherein an air-fuel mixture flows from the chamber portion side into the combustion chamber via the communication passage by operating the control valve, which engine is intended to eliminate scattering of fuel in the chamber portion due to splashing of part of the stream of fuel sprayed from a fuel injector. A portion, on the chamber portion side, of the communication passage is taken as a gas passage for communicating the control valve to the chamber portion. A fuel injector for injecting fuel is provided at a mid point in the gas passage via a connection passage in such a manner as to be directed to the inner wall surface of the gas passage while being slightly tilted toward the control valve. A fuel sump recess is provided in a cylinder block at a boundary between the control valve and the gas passage, and fuel is injected in the recess.

摘要： An internal combustion engine includes a combustion chamber, a chamber portion, and a communication passage for communicating the combustion chamber to the chamber portion. A valve for opening/closing the passage allows a high compression gas to be charged into the chamber portion and an air-fuel mixture to be injected from the chamber portion into the combustion chamber. A lubricating system keeps the opening of the passage to the combustion chamber and a surface of a piston facing to the opening well lubricated. The lubricating system includes an oil supply hole opening in a same direction as the opening of the passage to the combustion chamber. The oil supply hole may be positioned under the opening of the passage, or may be provided between a lower edge of the opening of the passage and a piston ring of the piston, when the piston is located at a bottom dead center.
