Title: Combustion chamber of subchamber type in diesel engine
Inventor: NAKANISHI KOUICHI
IPC: F02B19/18
Filed: 1981-05-26
Abstract: PURPOSE:To improve a combustion characteristic at low speed high load operation of an engine, by communicating main and subcombustion chambers through a communication hole, speading sectional area of its passage from the main chamger side to the subchamber side further setting area ratios of both end openings of the communication hole for area of a piston top to within a specific range. CONSTITUTION:The captioned engine is formed such that a main combustion chamber 4, formed by a piston 1, cylinder liner 2 and cylinder head 3, and a subcombustion chamber 9, constituted with a lower part by a cap 5, are communicted by a communication hole 6 drilled in the cap 5. In this case, the communication hole 6 is formed with its sectional passage to oval shape, simultaneously its sectional area is arrnged with a side of the subcombustion chamber 9 winder further with a side of the main combustion chamber 4 narrower. While ratio of area in an opening at the side of the subchamber 9 of the communication hole 6 to area of a top of the piston 1 is st to within a range of 1.6-2.5%, further raio of area in an opening at the side of the main chamber 4 to the area of the top of the piston 1 is similarly set to within a range of 0.7-1.6%. In this way, smoke concentration at low speed high load operation can be decreased to attain the desired end.

Title: Control device for vehicle
Inventor: YATOMI SATOSHI
IPC: B60W10/11
Filed: 1987-03-31
Abstract: PURPOSE:To prevent an automatic transmission from being shifted down unnecessarily by switching an intake air feed passage and prohibiting the shift of the speed change stage of the automatic transmission for the preset time when a main throttle valve control system fails. CONSTITUTION:When a control unit 12 judges that a main throttle valve control system fails, it turns off the electromagnetic clutch 14 of a throttle valve drive motor 13 to close a throttle valve 10. Furthermore, it opens a negative pressure side solenoid valve 21 and closes an atmosphere side solenoid valve 22 to open a shutter valve 19. Thereby, the intake air quantity is adjusted by an auxiliary throttle valve 18 mechanically connected to an accelerator pedal 16, and the traveling performance is secured. A signal to shift the speed change stage of an automatic transmission 25 is prohibited from being outputted until the preset time elapses after the failure occurs. Accordingly, the speed change stage is prevented from being shifted unnecessarily by the accelerator operation of a driver in response to the temporary reduction of the output, and the deterioration of the driving performance can be prevented.
