摘要： In a knocking control device comprising an exhaust bypass valve driven by the diaphragm actuator and a knocking control circuit, the amount of bypassed exhaust gas is adjusted in accordance with the knocking, the upper and lower limits regarding the opening degree of the control valve are determined in accordance with the opening degree of the throttle valve and the signal determining the upper limit concerning the opening degree of the control valve is prior to the signal determining the opening degree of the control valve due to the knocking signal when the opening degree of the throttle valve is changed. Thus, an increase in the output of the engine and an improvement in specific fuel consumption is achieved and the durability of the engine is improved due to the elimination of knocking and a decrease in the temperature of the exhaust gas.

摘要： In an internal combustion engine having a plurality of cylinders, an air-fuel ratio signal is sampled and held for a selected cylinder, and an air-fuel ratio feedback amount is calculated in accordance with the sampled and held air-fuel ratio signal. During a learning control, a cylinder on the leanest side is determined by changing the selected cylinder. During a feedback control without the learning control, the selected cylinder is fixed as the cylinder on the leanest side.

摘要： An intake system for intercommunicating a carburetor and a combustion chamber of internal combustion engines which has a cylinder head, an intake port provided in the cylinder head, an intake valve located in the intake port and an exhaust manifold communicated with the combustion chamber. At least two intake passages are provided to join together at that part in the intake port which is immediately before the intake valve. One of the intake passages passes through the exhaust manifold, whereby the atomized fuel particles in an air-fuel mixture to be sucked in the combustion chamber can be positively vaporized without accompanying high temperature rising of the mixture.
