IPC: F02B25/16
Filed: 1994-12-27
Abstract: PURPOSE: To optimize the return timing of an exhaust reflected wave, and enhance engine performance by detecting the air-fuel ratio by introducing burnt gas from an introducing port only in a period until a scavenging flow reaches the introducing port of an auxiliary exhaust passage after ignition. CONSTITUTION: An ECU 15 calculates the target air-fuel ratio optimal for its operation condition on the basis of throttle opening and rotating speed of a two-cycle engine 1 detected by a throttle valve driving actuator 12 also serving as a sensor. On the other hand, an exhaust pipe length variable device 50 arranged in an exhaust pipe 8 is composed of a longitudinally movable variable convergence 51. Then, the ECU 15 finds the air-fuel ratio of burnt gas on the basis of a detecting value of an O2 sensor 30 arranged in an auxiliary exhaust passage 29, and controls the exhaust pipe length variable device 50 on the basis of a difference between this detecting air-fuel ratio and the target air-fuel ratio.  Therefore, an exhaust reflected wave reflected by an end part of the exhaust pipe 8 is regulated so as to return to a main exhaust port as a negative pressure wave just before an exhaust stroke of the next cycle, and exhaust efficiency of an engine 1 is enhanced, and performance can be improved.

Inventor: OGATA MASAO
IPC: G11B7/09
Filed: 1993-11-30
Abstract: PURPOSE:To decrease the galling of a metallic mold and to obtain a magnetic circuit which is of a small sized, right in weight, of a low cost and of high sensitivity by making the form of a permanent magnet so that widths of both end parts of the sectional plane of it are wider than the width of a center part. CONSTITUTION:In a conventional permanent magnet 50, an yield is lowered by the galling of the metallic mold and the generation of a crack because it is of a complicated form having the differences of level at its four corners. Contrary, this permanent magnet 1 is formed so that widths X of both end parts of the sectional plane are wider than the width X0 of the center part and then the center part is a flat. In the case of this shape, since the form of the magnet is nearly of simple block-shaped, problems such as the decrease of the yield, etc., can be improved. Moreover, in this case, since the width of the magnet 1 is made smaller than that of a yoke 8 and the leakage flux to the yoke 8 is decreased as compared with the conventional magnet, sensitivities of a focusing coil 5 and a tracking coil 6 are increased.
