Title: Combustion chamber for subsidiary chamber type engine
Inventor: IMOTO KOUJI
IPC: F02B19/08
Filed: 1983-06-14
Abstract: PURPOSE:To lower the specific fuel consumption of an engine and to purify the exhaust gas of the same, by making the sectional area of the passage of a nozzle port of a subsidiary combustion chamber at the opening on the side of the subsidiary combustion chamber greater than that on the side of a main combustion chamber by enlarging the portion of the nozzle passage located near the opening on the side of the subsidiary combustion chamber. CONSTITUTION:A nozzle port 3 of a subsidiary combustion chamber 2 is curved in the manner of satisfying the following relationship, theta1<theta2, where theta1 is the discharge angle of the opening end located on the side of a main combustion chamber 1 and theta2 is the discharge angle of the opening end located on the side of the subsidiary combustion chamber 2. The portion of the wall surface of the nozzle passage located on the side of the center line B-B of a cylinder and near the opening on the side of the subsidiary combustion chamber 2 is enlarged in a straight form such that the sectional area f2 of the nozzle passage of the opening located on the side of the subsidiary combustion chamber is made greater than that f1 of the nozzle passage of the opening located on the side of the main combustion chamber 1. With such an arrangement, gas flow from the subsidiary combustion chamber 2 to the main combustion chamber 1 is made smooth and penetration of jet in the main combustion chamber 1 is increased, so that mixing and combustion of fuel are promoted. Thus, it is enabled to lower the specific fuel consumption, to purify the exhaust gas, to reduce the noise, to increase the engine speed and to improve the starting performance of the engine.

Title: Disconnection detecting method for signal circuit and disconnection detecting system using the same detecting method
Inventor: WADA TAKETSUGU
IPC: G08B29/06
Filed: 1989-04-25
Abstract: PURPOSE:To easily detect the incomplete disconnection of a signal circuit by transmitting the pulse signals in a fixed cycle with superposition on the DC voltage, charging the capacitor set at the termination of the signal circuit for each output of the pulse signal, and comparing the peak value of the charging current with a prescribed level. CONSTITUTION:The pulse signal of peak value V1 is superposed on the DC voltage V of a signal circuit l and transmitted, and a capacitor C is charged by the pulse signal via the circuit l. The charging current of the capacitor C increases and decreases according as decrease and increase of the resistance value of the circuit l respectively. As a result, the disconnection can be decided when the charging current of the capacitor C is reduced less than a prescribed level after monitoring the peak value of the charging current at the termination side of the circuit l. Thus the disconnection phenomena including the incomplete disconnection of the line can be easily detected.
