摘要： A spark plug is located in a combustion chamber so as to decrease the combustion time of the charge inducted into the combustion chamber. The charge is formed, before inducted into the combustion chamber, by mixing an air-fuel mixture and substantially inert gas such as exhaust gas so that the weight ratio of the fuel combusted in the combustion chamber and the substantially inert gas falls within the range from 1:13.5 to 1:18.5 during normal engine operation.

摘要： A vacuum signal is produced, which is representative of a function of the flow rate of engine taken air and which is employed for directly or indirectly operating a diaphragm unit of an exhaust gas recirculation control valve, by admitting atmospheric air into a vacuum from a vacuum source by employing a solenoid valve in such a manner that the solenoid valve varies the amount of admitted atmospheric air in accordance with the flow rate of engine taken air.

摘要： An auxiliary flow control valve is disposed in an exhaust gas recirculation passageway at a location upstream of a main flow control valve controlling the flow rate of exhaust gases recirculated into an intake system. Two conduits communicating with an intake manifold communicate with a vacuum chamber of a servo motor controlling the main flow control valve. One of the conduits has formed therein a restriction to limit the flow rate of fluid therethrough. A check valve is disposed in the other conduit to close the same when the vacuum in the intake manifold is increased and constant and to open the other conduit when the vacuum in the intake manifold is reduced.
