Abstract: The present invention relates to a powder for sintering containing a mixture of a metal powder and metal oxide particles having an average particle diameter of 5 nm or more and 200 nm or less, and to a sintered body.

Abstract: A fuel injection equipment including a fuel injector for injecting fuel into a fuel injected space of an internal combustion engine and a fuel pump is disclosed. A generator which is driven by the internal combustion engine and has characteristics of being increased in output voltage or output current with an increase in engine rotation speed is used as any one of an injector driving power supply for feeding the fuel injector with an exciting current through an injector trigger circuit and a fuel pump driving power supply. Use of the generator as the power supply permits the fuel injection equipment to be controlled without requiring a complicated control circuit.

Abstract: A method for controlling ignition timing of an internal combustion engine and an apparatus for practicing the method are disclosed which are adapted to determine ignition timing depending upon information on an engine speed detected, to thereby control the ignition timing. Pulsin signal counting is started evey time when a reference signal is generated from a signal generator to count first, second and third numbers N1, N2 and N3 of pulse signals, to thereby obtain information on an engine speed depending upon the difference between time T2 when the counting of the second number of pulse signals is completed and time T1 when that of the first number of pulse signals is completed, and then the information is used for obtaining ignition timing measuring time equal to a period of time between time T3 when the counting of the third number of pulse signals is completed and target ignition timing T1.
