Title: Misfire detection method by air-fuel ratio controller of internal combustion engine
Inventor: UENO SADAYASU
IPC: F02D41/22
Filed: 1987-04-22
Abstract: PURPOSE:To discriminate a misfire cylinder, display it and interrupt the fuel injection in that misfire cylinder by comparing the output pattern or compensated pattern of an air-fuel ratio detector with the stored misfire pattern condition such as a crank position. CONSTITUTION:The CPU inside a control unit 6 receives the detected signals from an air-fuel ratio sensor 5, an air flow meter 2, a crank angle sensor 3 and so on. When the fluctuations in r.p.m and the fluctuation in air flow rate are below the respective stored data, the CPU determines that the engine state is in the normal state. When the normal engine state is confirmed, the CPU reads the compensatory value of the air-fuel ratio (or the output value of the air-fuel ratio) for each cylinder. Next, the CPU calculates the average of the compensated air-fuel ratios of the cylinders and calculates an error between the detected air-fuel ratio in a cylinder and the average ratio. When this error is greater than the misfire reference error data stored in the ROM, the CPU determines that a misfire occurs in said cylinder, displays said misfire, and inhibits the fuel injection from the fuel injector 7 of said cylinder therein.

Title: Low speed system for carburetor
Inventor: ABE TETSUO
IPC: F02M3/09
Filed: 1983-06-01
Abstract: PURPOSE:To maintain air fuel ratio constant with a fuel flow which corresponds to the quantity of air intake all the time by controlling negative pressure at the idle port of a carburetor corresponding to the negative pressure in a suction pipe. CONSTITUTION:A low speed fuelsystem 5 is provided with an air passage 9 having a control valve 11. The negative pressure at an idle port 8 decreases in such a way that the negative pressure in the suction pipe downstream from the throttle valve 4 is delivered to the chamber 15 of a diaphragm 14 via pipe 17 and the valve 11 is opened against the resistance of a spring 16 according to the negative pressure, then air is delivered via a passage 9. Thus, although the negative pressure in the suction pipe is intensified and large quantity of fuel tends to flow from the idle port 8, air coming through the passage 9 decreases negative pressure, as a result, the fuel flow can be reduced and quantity of fuel flow can be set in response to the quantity of intake air.

Title: Hydraulic buffer
Inventor: IMAIZUMI TOMIO
IPC: F16F9/32
Filed: 1988-04-20
Abstract: PURPOSE:To reduce the size of a buffer and to prevent air from stagnating in the interior of a liquid chamber by setting the capacity in a range positioned above the upper end of a cylinder in a close space larger than the effective capacity in the cylinder, which is produced when a piston reaches the other end of the cylinder. CONSTITUTION:A cylinder is retained substantially vertically, with a bottom cap 27 down, and the interior of the bottom cap 27 is filled up to a level indicated by a broken line with oil. After that, the cylinder is put in the substantially horizontal state, so that oil in the bottom cap 27 is fed into liquid chambers 20a, 20b of a cylinder 20 through a communicating hole 31, and space corresponding to the volume of fed-in oil is formed in the bottom cap 27. Then, surplus oil due to a decrease in the capacity of the cylinder 20, which results from a piston rod 23 enters the cylinder 20, is absorbed by the above space. In this arrangement, a reservoir chamber 27f is disposed in the outer periphery of the end portion of the cylinder 20, so that the total length can be reduced, and air can be prevented from staying in the interior of the liquid chambers.
