Title: Engine control system
Inventor: SUEMATSU TOSHIO
IPC: F02D41/22
Filed: 1982-06-23
Abstract: PURPOSE:To prevent accidents due to erroneous operations of a group of sensors at the time other than idling by a method wherein an engine control system transmits no control signal to a bypass valve control section or transmits a DC signal of a predetermined level except when the engine is idling. CONSTITUTION:The control system for the engine 2 comprises the sensors 4, 6, 8, 10, 12 and 14, the engine control section 18 and the bypass control section 20 adopted to control the lifting amount of the bypass valve 30 in a pipe passage bypassing a throttle valve through the control signal 18 whose duty ratio varies depending on the operation condition of the engine 2. Except when the engine 2 is idling, the control signal including a higher harmonic component and having a variable duty ratio is not transmitted to the bypass control section 20 so that it is made possible to prevent noises from overlapping the outputs of the sensors. Further, when the engine is not idling, the bypass passage is closed and the air pressurized by a supercharger 44 prevents the lowering of the pressure of the sucked air.

Abstract: PURPOSE:To perform effectively the treatment for improving the residual stress in the welded parts of a branched pipe by forming a high frequency induction coil m a specified shape in case of improving the residual stress of the welded parts by heating the whole parts of the welded parts of a base pipe and a branch of the branched pipe. CONSTITUTION:Since the residual tension stress is caused in both the welded parts 4, 6 of a branched pipe 1 in which a branch 5 is welded 6 to a nozzle stub member 3 welded 4 to a base pipe 2, the branched pipe 1 has such faults that the strength of the pipe 1 is lowered and also its corrosion is increased, if leaving as it is. To convert the residual tension stress into compression stress, a high-frequency induction heating coil 7 is divided into an upper side part 8 and a lower side part 9 by means of a horizontal plane contg. the centerline of the base pipe 2. Furthermore, the upper side part 8 is divided into a branched part 10 and a base pipe side part 11 and both the parts 10, 11 are respectively divided into two parts in the vertical direction and uniform magnetic flux density distribution is given for the surrounding parts by means of the electric conduction. The strength and the corrosion resistance of the welded parts are improved by heating uniformly the base pipe 2 and the branch 5 part and transferring the residual tension stress caused at the time of the welding to the compression side.
