摘要： An engine equipped with an electronically controlled fuel injection system is provided with an EGR control system which accurately regulates the EGR rate in accordance with a vacuum signal produced at a venturi formed in the intake passageway of the engine, under low and medium load engine operating conditions. However, under high speed and high load engine operating conditions, a part of intake air is bypassed through a bypass passage connecting the upstream and downstream sides of the venturi in order to prevent increase of the flow resistance of the intake air.

摘要： A multiple-cylinder spark-ignition internal combustion engine for an automotive vehicle, in which the ratio of the inactive compounds in the mixture gases produced in each combustion chamber to the fuel component in the combustible mixture inducted into the chamber is maintained within a predetermined range and the spark plug for each engine cylinder is arranged so that the flame travel from the spark plug is reduced to a minimum for promoting the combustion reaction to proceed in the least possible time. Improvements are further made in respect of the exhaust gas recirculation rate, the location and measurements of the spark plug, the configurations and measurements of the engine cylinder and the arrangement of the intake and exhaust ports so as to reduce the concentrations of toxic compounds in the exhaust gases without impairing the performance efficiency of the engine.

摘要： An engine is provided with two spark plugs in each combustion chamber to ignite stoichiometric air-fuel mixture mixed with a large proportion of inert gases to lower NOx emission level. The engine is equipped with hydraulic valve lifters which are mechanically connected to intake and exhaust valves to control the valve overlap of the intake and exhaust valves. By the action of the valve lifters, the valve overlaps are increased in the normal driving operation range of the engine to prevent discharge at the terminal stage of exhaust valve opening exhaust gases containing a considerably large amount of hydrocarbons.

摘要： A multi-cylinder internal combustion engine has siamesed exhaust ports each of which is shared by two adjacent cylinders. The valve timings of intake and exhaust valves of the two cylinders are so adjusted that flow of the exhaust gases from one cylinder is not obstructed in the siamesed exhaust port by the flow of the exhaust gases from the other cylinder in order to prevent power outputs of the two cylinders from being unbalanced.

摘要： An internal combustion engine of the reciprocating piston type, which is provided with an exhaust gas recirculation circuit to suppress the formation of NOx and has two or three spark plugs for each combustion chamber. There is a substantial overlap of the opening periods of exhaust and intake valves, so that a portion of the combustion gas is left unexhausted. The combustion chamber has a simple shape such as hemisphere, and the spark gaps of the plural spark plugs are arranged distant from each other in each combustion chamber so as to respectively share approximately equally divided portions of each combustion chamber. The number of the spark plugs is two when the volume of the recirculated exhaust gas, including the unexhausted combustion gas, is about 50% at the maximum of the volume of air admitted into the combustion chamber but three when the recirculated exhaust gas amounts to about 60% of the air at the maximum.
