IPC: F02D23/00
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To display large braking force by providing a boost pressure control means executing boost pressure control in a different mode from the time of normal operation when an exhaust valve is opened in an engine braking device controlling opening/closing of the exhaust valve by supplying/discharging fluid pressure in an engine with a supercharger. SOLUTION: A brake unit 6 is provided at a top part of one exhaust valve 3a between two exhaust valves 3a, 3b opened/closed at normal valve timing by the rotation of a cam through a locker arm. The brake unit 6 is so constituted that a piston is pushed down by oil pressure when an operation switching valve 7 is opened at the 'ON' time of an engine brake switch so as to push down the exhaust valve 3a. When an engine brake is operated, a controller 8 judges the presence of load. At the loaded time, large braking force is required, so that target boost pressure is computed to heighten boost pressure at the loaded time compared to the unloaded time to control a waste gate valve 19 or the like.

Filed: 1992-09-30
Abstract: PURPOSE:To remarkably improve a forgery prevention effect by disabling the confirmation of a hologram image even by simply imparting a spherical wave or a plane wave by a collating a pattern generated by diffracted light from a second hologram with a reference pattern decided in advance.
