Title: Ignition timing control method for engine
Inventor: MATSUO NORITAKA
IPC: F02P5/15
Filed: 1985-09-24
Abstract: PURPOSE:To improve the output of an engine in an engine speed range higher than one for the maximum torque by controlling the ignition timing to be delayed in angle from a specified value for increasing the exhaust gas temperature when the exhaust gas temperature in an exhaust pipe is dropped. CONSTITUTION:While an engine runs, an exhaust gas temperature signal from a temperature sensor 10, and an engine speed signal from an engine speed detector 13 are inputted into an ignition timing control device 12 through amplifiers 11 and 14. In this control device 12, the optimum exhaust gas temperature for the engine speed is read out from a memory means so as to allow the outputted optimum exhaust gas temperature to be compared with the inputted actual exhaust gas temperature. And an ignition device 15 is controlled in such a way that the ignition timing is set so as to allow the exhaust gas temperature to come close to the optimum exhaust gas temperature. That is, when the actual exhaust gas temperature is below the optimum exhaust gas temperature, the ignition timing is controlled to be delayed in angle from a specified value for increasing the exhaust gas temperature so as to increase the output of the engine.

Title: Transmission gear operation unit
Inventor: INOUE YOSHIO
IPC: F15B15/24
Filed: 1984-10-12
Abstract: PURPOSE:To enable both hitting tone of a transmission gear and wear generated at engagement of the gear to be prevented, by reducing the output of a piston rod through restriction of a free piston in its advance after completion of synchronization of the transmission gear. CONSTITUTION:When both a fixed piston 10 and a free piston 11 move from their neutral positions to the right by more than l1 distance, a stopper ring 35 hits one side restriction part 36 of a groove part 34. Accordingly, the free piston 11 is restricted in its advance while the fixed piston 10 moves further to the right apart from the pushing step pat 21 of the free piston 11. In this case, the output of a piston and 8 is small, because the fixed piston 10 is not pushed in the moving direction by the free piston 11. Therefore, neither hitting tone nor wear can take place at the stopper of the piston rod 8 or on the gear side of a transmission gear.
