Title: Combustion method for four-cycle diesel engine, and combustion device
Inventor: AKEDA MASAHIRO
IPC: F02B1/12
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To drastically reduce an ignition delay time of main injection fuel to reduce a pressure increase rate of in-cylinder pressure by igniting the main injection fuel with auxiliary combustion flame. SOLUTION: In an intake stroke, auxiliary injection fuel 3 is sprayed onto a high-temperature circumferential wall face part 6a of a combustion chamber 2 to form a fuel liquid film 3a on the circumferential wall face part 6a. During a main injection early time E after the auxiliary injection, the fuel liquid film 3a is rapidly evaporated by retention heat of the high-temperature circumferential wall face part 6a to form evaporated mixture of a concentration enhanced to within a combustible region in a combustion chamber peripheral part 9a. In a compression stroke B, auxiliary combustion of the evaporated mixture of the concentration within the combustible region is started by compression heat, and auxiliary combustion flame generated by the auxiliary combustion is maintained until a start time (i) of main injection of main injection fuel 4.  In a nearly final stage of the compression stroke B, the main injection fuel 4 mainly injected from a fuel injection nozzle 1 is ignited by the auxiliary combustion flame to start combustion.

Filed: 1987-10-20
Abstract: PURPOSE:To speed up printing by utilizing an arm comprising a thin sheet that is folded at the sides thereof so as to increase the intrinsic frequency of the arm in the direction in which a printing operation is performed, as well as to eliminate any deleterious effect that would be caused by the oscillation mode in the direction normal to the printing-operating direction. CONSTITUTION:An arm 11 comprising a thin sheet that is folded at the sides thereof has a printing wire 17 connected to one end thereof and is inserted in a groove 18a provided in a first connecting member 18 at the other end to be brazed in place. Since the arm is formed of a thin sheet and is hence light, the intrinsic frequency of a printing hammer is increased, and high-speed printing can thereby be attained. In addition, since the arm is folded at the sides thereof, the rigidity of the arm in the direction normal to the direction in which a printing operation is conducted is markedly improved, whereby the frequency of the oscillation mode in this direction is increased, and deleterious effects that would be caused by this oscillation can thus be eliminated. Furthermore, since the arm is inserted in a groove provided in a connecting member and is brazed in place, the productivity of the printing hammer is improved, and hence it is possible to reduce the production cost thereof.
