摘要： In order to avoid the formation of smoke and HC when the compression ratio of a swirl chamber type Diesel engine is lowered either by design or by operation in rarified atmospheres, the fuel injector is located on one side of the center axis of the swirl chamber so as to maximize the distance for which the injected fuel can travel before contacting a wall of the chamber and the auxiliary transfer port through which a fraction of the injected fuel is fed to the main combution chamber is arranged so that the axis thereof intersects the axis of the fuel injector and therefore the trajectory along which fuel is injected, at a point defined within the swirl chamber per se and on the opposite side of the center axis with respect to the fuel injector.

摘要： In order to promote a good flame dispersion within the combustion chamber of a swirl chamber type Diesel engine, a shaped recess formed in the piston crown is arranged to have a trench portion into which the flame from the swirl chamber is injected and mirror image flame dispersion portions on either side of the trench which terminates at the periphery of the piston crown. This arrangement inhibits the formation of secondary flame flows which tend impede desirable patterns within the flame disportion portions and simultaneously enlarges the dispersion area. In addition, careful selection of the dimensions of the transfer port which interconnects the swirl chamber and the main combustion chamber, and the various sections of the shaped recess, promotes further reductions in HC and smoke emissions.
摘要翻译：为了在涡流室型柴油发动机的燃烧室内促进良好的火焰分散，形成在活塞冠部中的成形凹部被布置成具有沟槽部分，来自涡流室的火焰被注入到该沟槽部分中，并且镜像火焰分散沟槽两侧的部分终止于活塞顶部的周边。这种布置抑制二次火焰流的形成，这阻碍了火焰不均匀部分内的期望图案，并同时扩大了分散面积。另外，仔细选择将涡流室和主燃烧室相互连接的输送口的尺寸以及成形凹槽的各个部分的尺寸，进一步降低了HC和烟雾的排放。

摘要： A fuel injection pump serves to periodically inject fuel into an internal combustion engine. A movable control member serves to determine the quantity of fuel injected during each fuel injection stroke in accordance with the position of the control member. A permanent magnet is movable together with the control member. A stationary magnetically-permeable member serves to conduct magnetic flux generated by the permanent magnet. The magnetic flux conducted by the magnetically permeable member depends on the position of the control member. A Hall element unit serves to sense the conducted magnetic flux and generate a first signal indicative of the actual position of the control member. A second signal indicates a desired position of the control member. A device, responsive to the first and second signals, serves to adjust the actual position of the control member to the desired position thereof.
