Abstract: PURPOSE:To determine optimal ignition time in consideration of purification of exhaust gas and consumption of fuel, by using a conventional negavite pressure spark advancement characteristic as a reference and opening or closing a changeover valve to control the application of negative pressure to a second negative pressure chamber. CONSTITUTION:A first and a second negative pressure chambers 13, 27 are provided. These chambers differ in operation starting negative pressure level from each other.

Title: High carbon steel excellent in punchability and hardenability
Inventor: FUNAKAWA YOSHIMASA
IPC: C22C38/00
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To improve punchability and hardenability by specifying respective grain sizes of carbide and ferrite. SOLUTION: This steel contains 0.2wt.% C and is composed essentially of carbide and ferrite, and further, the grain sizes of carbide and ferrite are regulated to <=2.0μm and 0.5-1μm, respectively. Hardenability is greatly affected by the grain size of carbide; that is, the surface area, in comparison with the total volume, of the carbide is increased by finely precipitating the carbide in the steel and the entering of the carbide into solid solution in the course of heating and holding is accelerated and, as a result, excellent hardenability can be obtained. Further, punchability is controlled by the grain size of ferrite; that is, the steel is softened with the increase of ferrite grain size and die life is prolonged, but the height of burr at the time of punching breaking is increased. Accordingly, the ferrite grain size is specified to a value in the above proper range in order to combine the quality of a punched product with die life.
