Title: Intake system for two-cycle internal combustion engine
Inventor: WATANABE HIDEO
IPC: F02B29/02
Filed: 1989-01-31
Abstract: PURPOSE:To reduce the extent of passage resistance as well as to keep off the promotion of enlargement in size by setting up a read valve in a joint between an intake passage and a crankcase corresponding to each cylinder, and constituting a carburetor so as to come nearer to the inverted V-shaped inside of an extension of a cylinder center axis and to go away from the extension as far as the upstream side of the intake passage. CONSTITUTION:An intake system consisting of a reed valve 40, an intake passage 42 and a carburetor 44 is set up an inverted V-shaped bank against a cylinder V shape to the shaft center of a crankshaft 22, and this inverted V shape has acuter angle than the cylinder V shape, while a center line of the intake passage 42 comes into contact with a circle of a diameter Dphi center ing on a crankshaft center 22a. Accordingly, the intake system is set up in the more inside than a cylinder center shaft extension. In addition, the intake passage 42 goes way from the extension in proportion as going to the upstream side. With this constitution, a sectional area of the intake passage 42 at the upstream of the reed valve 40 is large enough, whereby bend loss in a flow passage becomes lessened, and since fresh air is taken in a cylinder 28 and a scavenging passage 32 from the reed valve 40, passage resistance is thus reduced. In addition, a widthwise interval in a position of the carburetor 44 is narrow, so that the promotion of any enlargement for an engine can be prevented.

CONSTITUTION:A moving quantity of a document 17 of a linear image sensor 1 in the longitudinal direction is measured by a rotary encoder 14 and a counter 15. A keyboard 12 has a function of designating the character insert mode, the character insert position and plural inserted characters, and generates a character select signal by a designated number when a counter 15 generates a start pulse SP at a pattern designation position and gives a ROM address of a character pattern designated in the timing to a ROM 13 and also fed to a priority circuit 16 in the same timing as the data from the linear image sensor 1 after shading correction. The priority circuit 16 uses a priority signal SY delayed slightly from the start pulse SP to input the data to an interface 8 in precedence over the data from the ROM 13.
