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.

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： 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： An interconnecting slot is formed between a main transfer port (heated by the passage of hot gases during an expansion phase) and an auxiliary transfer passage (cooled by the passage of non atomized fuel injected into the swirl chamber with which the main and auxiliary ports are associated) to prevent thermal stress damage which would otherwise be apt to occur.
