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： 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.

摘要： A first plunger pump serves to inject fuel into the combustion chamber of an internal combustion engine during first periodical compression strokes as the crankshaft of the engine rotates. A second plunger pump serves to inject fuel into the combustion chamber during second periodical compression strokes as the crankshaft rotates. The maximum fuel injection quantity during each second compression stroke of the second plunger pump is smaller than that during each first compression stroke of the first plunger pump. A sensor detects load on the engine. A mechanism serves to advance the timing of the first compression strokes relative to that of the second compression strokes with respect to the rotational angle of the crankshaft as the detected engine load increases. The characteristic curve of the rate of the sum of the fuel injections effected by the first and second plunger pumps with respect to the rotational angle of the crankshaft can vary in accordance with the engine load.

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.
