摘要： A cylinder block for an automotive in-line multiple-cylinder internal combustion engine, comprising an outer wall structure, an elongate cylinder row structure spacedly located within the outer wall structure including a plurality of cylinder sections whose neighboring cylinder sections are integrally connected with each other, and first and second connecting wall portions which integrally connect the cylinder sections at the extremities of the cylinder row structure with the outer wall structure so as to define independent coolant passages at the opposite sides of the cylinder row structure, thereby improving flexural and tortional rigidities though produced by die-casting.

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： The cooling system of an engine consists of a cooling fan for cooling an engine coolant and a drive pulley which is, in turn, drivably rotated by the crank shaft of the engine. The mechanical connection between the drive pulley and the cooling fan is released during engine acceleration under urban area cruising conditions, in order to stop or slow down the rotational speed of the cooling fan.

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.

摘要： Two spark plugs are disposed in each combustion chamber of an internal combustion engine to effectively ignite the air-fuel mixture which is mixed with a relatively large amount of the exhaust gases which is supplied into the combustion chamber from the exhaust system of the engine. Each spark plug is located so that the electrodes thereof lie at the same height as the center of an intake valve seat in the combustion chamber.

摘要： Intake and exhaust valves and an intake port of an internal combustion engine are arranged so that strong swirl turbulence of the inducted air-fuel mixture is produced in the combustion chamber. The swirl turbulence improves the combustion of the air-fuel mixture mixed with exhaust gases, initiated by the ignition with two spark plugs disposed in the combustion chamber.
