Abstract: PURPOSE:To securely detect abnormal combustion due to a lowering in oxygen concentration, by providing a first abnormality discriminating means for discriminating abnormal combustion, and a second abnormality discriminating means capable of discrimination between abnormal combustion due to a lowering in oxygen concentration and abnormal combustion due to other cause. CONSTITUTION:A microcomputer 51 is provided therein with a first abnormality discriminating means for discriminating abnormal combustion on the basis of a signal from a flame detecting means 52, an electric energy controlling means 57 for determining an electric energy W to be supplied to a heater so as to eliminate the deviation of a temperature based on a signal from a temperature detecting means 53 from a preset target value, based on the devia tion, a combustion quantity controlling means 58 for determining a combustion quantity and controlling an oil feeding means 55, and a second abnormality discriminating means 59 operated when combustion is discriminated as abnormal combustion by the first abnormality discriminating means 56. When combustion is discriminated as abnormal combustion by the first abnormality discriminating means 56, the second abnormality discriminating means 59 compares a required electric energy obtained from the combustion quantity with the electric energy supplied being supplied to the heater, and performs abnormality discrimination based on the deviation between the two electric energy values compared. Therefore, it is possible to discriminate abnormal combustion due to 8 decrease in combustion quantity and abnormal combustion due to a lowering in oxygen concentration from each other.

Title: Suction cylinder for fuel injection apparatus
Inventor: MIKI KEIJI
IPC: F02M69/00
Filed: 1978-02-10
Abstract: PURPOSE: To prevent deterioration in fuel-air ratio common to the increase in the opening of a throttle valve by means of a butterfly valve operatable by the motive pressure of a gas, arranged on the upstream of the throttle valve in a suction passage.  
     CONSTITUTION: A butterfly valve 10 is arranged on the upstream of a throttle valve 2 in a suction passage 5 and at the bottom of the end of a by-path 4. When no gas flows through the passage 5, a counter-weight 13 allows the valve 10 to close the passage 5. When a gas starts flowing, the motive pressure of the gas turns the valve 10 clockwise to let the gas flow therethrough. When a large amount of gas is supplied for rapid acceleration, the counterweight 13 checks the increase in the opening of the valve 10, avoiding rapid opening of the valve 10. Thus, the valve 10 slows down the increase in the amount of gas in such a manner that the engine speed slowly reaches the desired value, avoiding disorder of the engine.
