摘要： PURPOSE:To increase the cleaning efficiency of exhaust gas and suppress a generation of harmful components after an engine is started, by feeding the exhaust gas to a catalytic converter through a bypass line and promoting the warming-up operation when the engine is in its warming-up operation. CONSTITUTION:When an engine is in operation warming-up, the bimetal element 47 undergoes no change and a valve rod 45 is pressed leftward by a spring 46, so the second chamber 36 is linked to an intake manifold 9 through paths 56, 48. While the first chamber 35 is communicated with an intake duct 21 through a path 57. Because of a small degree of opening of a throttle 14, the intake duct 21 is at a pres sure almost equal to the atmospheric pressure, and the intake manifold 9 is at a negative pressure. This causes a diaphragm 33 to be pressed into the second chamber 36 to allow a rod 34 to open a waste gate valve 29, and the exhaust gas is fed to a catalytic converter 24 through a bypass pipe 26 without passing through a turbine T of a turbocharger 13.

摘要： PURPOSE:To achieve an alleviation of the supercharging efficiency of an internal combustion engine and heat load to an oxygen sensor installed in its exhaust system by providing a by-pass pipe on an exhaust pipe which communicates to the turbine of a turbo-charger so as to control the amount of exhaust gas by utilizing of the engine temperature and negative pressure. CONSTITUTION:A turbo-charger 13, which comprises a compressor C and turbine T, is provided with an intake system 9 and exhaust system 12 of an engine 1. In the exhaust system 9, are provided a pipe 26 by-passing over the turbine T and a control valve 29 adapted to open or close the pipe 26, and an oxygen sensor 38 and ternary catalytic converter 24 are also installed in the exhaust system 9 at a position downstream the by-pass pipe 26. The valve 29 is actuated by an actuator 32 driven by a negative pressure, in addition to that, the second chamber 36 of the actuator 32 is capable of introducing a negative pressure from an intake pipe via a change- over control valve 40 and a check valve 53. The valve 40 is opened when the temperature of cooling water 42 exceeds a predetermined value so as to introduce the negative pressure into the second chamber 36, resulting in an opening of the valve 29. A certain degree of negative pressure is also led into the first chamber 35 of the actuator 32 in accordance with the volume of air intaken. The opening degree of the valve 29 is adjusted by the pressure difference between the first and second chambers.

摘要： PURPOSE:To greatly accelerate the combustion speed of an engine under low load by providing a secondary throttle valve in each suction passage running behind a primary throttle valve, and an auxiliary suction passage for bypassing the secondary throttle valve. CONSTITUTION:Under low load operation where a primary throttle valve 25 opens little, the pressure in a suction duct 24 comes approximately equal to the atmospheric pressure. On the other hand, the pressure in a suction manifold 22 downstream the primary throttle valve 25 is greatly reduced to a negative pressure, thereby causing each secondary throttle valve 26 to be closed completely as shown by a dotted line 26a. Branch pipe 30 forcedly leads air fuel mixture at a high speed into appropriate combustion chambers 5, in each of which powerful swirl is generated as indicated by an arrow W. Each swirl greatly accelerates the combustion speed under low load. Under a high load operation, as each of the secondary throttle valve 26 is kept nearly closed at a position 26b, knocking can be prevented.

摘要： PURPOSE:To suppress the rotation bending deformation of a shaft section by coupling the shaft section of a ceramic turbine wheel with the shaft receiving hole of a metal support shaft via a tapered portion. CONSTITUTION:A tapered boss section 14a and a columnar tip section 14b are provided on the shaft section 14 of a ceramic turbine wheel 15, and this shaft section 14 is coupled with a shaft receiving hole 16 formed in a metal support shaft 11 and provided with a columnar back section 16a and a tapered opening section 16b. Accordingly, even if the shaft section 14 and the support shaft 11 are thermally deformed, the coupling gap is not changed due to the tapered structure, thus the rotation bending deformation of the shaft section 14 can be suppressed.

摘要： PURPOSE:To prevent the lowering of the output of the Diesel engine at the time of speed reduction during the high speed operation of the engine by a method wherein a vehicle speed detecting switch is attached to the intake throttle valve control device in series with an acceleration switch by the ON-OFF operations of which the control device is operated. CONSTITUTION:A switching device comprising a rod 17 and a diaphragm 16 is attached to an intake throttle valve 14 of a Diesel engine provided with a turbocharger and the negative pressure from a negative pressure tank 24 is supplied to the diaphragm 16 through changeover valves 21 and 23. Further, the vehicle speed detecting switch 29 is provided in a drive circuit of a relay switch 27 for controlling the changeover valve 21, in series with the acceleration switch 28. Thus, when the engine is operated at a speed higher than a predetermined speed, the accelerator is returned to its original position to enable a gear change operation to be made so that even if the switch 28 is turned ON, the switch 29 is kept ON to keep the valve 21 ON and the atmospheric air is introduced into diaphragm chambers 18 and 19 to thereby keep the throttle valve 14 opened to a sufficient degree.

摘要： PURPOSE:To check the occurrence of knocks by a method wherein a specific cylinder is put in a state in which the knocks tend to occur by controlling an air fuel ratio of a mixed gas and the occurrence of the knocks in the specific cylinder is detected, in a high load operation region. CONSTITUTION:A resistor 27 is inserted in a control circuit of a fuel injection valve 12 of a cylinder 5 and a knock senser 35 is provided near the cylinder 5. At the high load operation requiring the amount of the fuel to be increased, a valve opening characteristic of the fuel injection valve 12 is changed by the resistor 27 as compared with other characteristics, the cylinder 5 is supplied with the mixed gas of the air fuel ratio closer to the theoretical air fuel ratio as compared with other cylinders, and the same is put in a state in which the knocks tend to occur as compared with other cylinders. Accordingly, the occurrences of the knocks in the cylinder 5 are detected by the knock senser 35, thereby enabling the knocks to be checked against the occurrence.
