Title: Overheat preventing method for speed control system pump
Inventor: MASAOKA MAKOTO
IPC: F04D15/00
Filed: 1981-08-20
Abstract: PURPOSE:To aim at economic operation free from overheating by setting up overheat preventing escape piping provided with a built-in solenoid valve as well as a flow meter in a pump discharge line, while providing the pump with a rotational speed signal generator, through which each signal of flow and rotational speed is inputted into an arithmetic unit and controlling the valve so as to release a minimum flow of liquid discharge which satisfies a fixed formula via the said escape piping. CONSTITUTION:A rotation signal Ni from the rotational speed signal generator installed in the pump and a flow signal Qi from the flow meter installed in the discharge line are inputted to an arithmetic unit and when these relationships between them are found to be Ni>=alphaQi (alpha: constant), a solenoid valve is fully opened, then the valve is kept up in a full-open state till the condition of Ni<= betaQi (beta: constant) is satified, and when it is satisfied, the solenoid valve is, in turn, fully closed. On the other hand, when the case is of Ni<alphaQi, the valve is left without being fully opened; solenoid valve operation is achieved after some time waiting for finding of the condition of Ni<betaQi.

Inventor: NISHIMURA HIROBUMI
IPC: F02B23/08
Filed: 1986-06-05
Abstract: PURPOSE:To obtain a high output engine by forming a combustion chamber for one intake port and exhaust port which are arranged in the direction of cylinder row in a four-valve engine and forming a skewish zone for the other intake port and exhaust port. CONSTITUTION:Two intake ports 14a and 14b and two exhaust ports 15a and 15b are arranged on a cylinder head 12 nearly at right angles to the direction of cylinder row. A combustion chamber 16 in nearly semicircular recessed form is formed between the intake port 14a and exhaust port 15a, and a skewish zone 18 in a minute gap is formed from a piston between the intake port 14b and the exhaust port 15b. A spark plug 28 is arranged close to the outer part of the intake and exhaust ports of the combustion chamber 16. Since, further, the first intake passage 20a is connected in the tangential direction of the intake port 14a, the intake mixed gas secures the direction performance by the wall surface of the combustion chamber 16, and swirl is not attenuated, and the combustion efficiency can be improved, and the scavenging around the spark plug is permitted. Further, since the position of the spark plug prevents the interference with the intake and exhaust passages, setting of a large diameter is permitted, and a high output can be obtaind by increasing the intake/ exhaust quantity.

Title: Idle rotational speed control device for internal combustion engine
Inventor: KAWAI KATSUHIKO
IPC: F02D41/14
Filed: 1989-05-24
Abstract: PURPOSE:To enhance the accuracy of control by compensating an integrated value of deviation between a detected rotational speed and a desired value in a feed-forward manner in accordance with a load status variation before the integrated value being limited within a predetermined range. CONSTITUTION:A status variable limiting means limits a status variable set by a status variable setting means, within a predetermined range, and an integrated value limiting means limits an integrated value of deviation between a detected rotational speed calculated by an integrated value calculating means and a desired value, within a predetermined value. A control value limiting means limits a control value which is obtained by a control value computing means from the status variable and the integrated value delivered from these limiting means, within a predetermined range, and an adjusting means controls the engine rotational speed to a desired rotational speed. In this arrangement, when a detecting means detects a load status variation, an integrated value correcting means corrects the integrated value at that time in accordance with the status variation, and accordingly, the control value is corrected in a feed-forward manner. Thus, the responsiveness is satisfactory even though a status variation occurs. Thereby it is possible to control the engine rotational speed in a desired condition.
