Abstract: PURPOSE:To make a detection circuit operate only when it is necessary by connecting a drain and a gate between the source of a N-channel type MOS transistor and a substrate voltage, and making a drain signal into a substrate voltage detection signal. CONSTITUTION:The source of a P-channel type MOS transistor PTrQp111 is connected to a power supply voltage, the gate of the transistor is connected to a control signal N100, the gate of NTrQn111 is connected to a control signal N100, and its source is connected to the drain and the gate of Qn112. Also, the source of Qn112 is connected to the drain and the gate of Qn113, and the source of Qn113 is connected to a substrate voltage VBB. The drain of QP111 is outputted as a substrate voltage detection signal N111 through a two-stage magnetic circuit. Then, when the signal N100 is a logical voltage 'L', the output logical voltage of the signal N111 is determined by the voltage of voltage VBB. In response to this, in the case of a logical voltage 'H', Qp111 is turned OFF, a current is does not flow from the power supply to a substrate, and the signal N111 is fixed to 'L'. Consequently, the detection circuit operates only when it is necessary, and a low power consumption can be realized.

Title: Control method for air-fuel ratio of variable suction swirl system internal-combustion engine
Inventor: OKUMURA TAKESHI
IPC: F02D41/00
Filed: 1984-03-12
Abstract: PURPOSE:To prevent the occurrence of failure in ignition, by a method wherein, in an internal combustion engine equipped with a suction negative pressure- operated varying swirl system, when the negative pressure of a suction pipe is below a given value, a fuel amount is increased. CONSTITUTION:From the number Ne of revolutions of an engine read in a step 1 and a pressure P of a suction pipe read in a step 2, a reference injection amount TAUb is determined in a step 3. In a step 5, it is decided whether the opening of a throttle read in a step 4 is brought to an operation range in which suction swirl takes place. In a step 6, a plug F, which indicates that swirl is not effected, is set. Since a valve for controlling swirl can not be operated when the negative pressure of the suction pipe is below a given value, a device is formed so as to protect against swirl when the negative pressure of the suction pipe is below the set value, and a fuel amount is increased. This prevents the occurrence of a failure in ignition.
