Abstract: PURPOSE:To dissolve the influence generated by back-blow of such as fresh air toward a supercharger, so as to reduce the drive loss and to raise the output, by setting check valves adapted to check a counter-blow of fresh air toward the pressure-charging means side, and setting a driving mechanism adapted to open exhaust valves earlier than intake valves. CONSTITUTION:In heavy load range of an engine, an intake air control valve 16 is opened, and on the other hand, an exhaust gas control valve 34 is closed. Then, exhaust valves 31a, 31b are opened according to the descendent motion of a piston, to blow-out the exhaust gas abruptly. Next, suction vales 21a, 21b are opened to blow-in the fresh air from suction ports 20a, 20b toward a combustion chamber 2, respectively, and by this matter, cross scavenging is performed by the exhaust gas and the fresh air. At this time, a counter-blow of the fresh air is prevented by check valves 18a, 18b. Next, a part of the fresh air is stored in exhaust ports 32a, 32b and an exhaust manifold 33 for a while, by exhaust pulse effect, and after that, the stored fresh air is pushed into the combustion chamber 2 as this fresh air is blown back. At this time, dynamic pressure which acts on intake ports 20a, 20b is checked by the check valves 18a, 18b, respectively.

IPC: F24H3/04
Filed: 1987-06-22
Abstract: PURPOSE:To prevent the visual indicator from flickering so it may not be distracting where there is a slight fluctuation in the room temperature etc. by continuing the supply of input signal for a certain period of time to the indicator which indicates the heating level based on the output from a heating level determining means. CONSTITUTION:A room temperature sensing means 1 senses the room temperature based on the signal from a room temperature sensor 2, and a heating level determining means 3 determines the heating level based on the deviation between the changing signal from the room temperature sensing means 1 and a preset temperature. A heating control means 4 controls the rate of heating on the basis of the signal from the heating level determining means 3. A data storing means 5 stores the signal from the heating level determining means 3 at regular intervals and supplies data to a heating level indicating means 6. By this constitution, even if room temperature data read in response to minutely changing room temperatures fluctuates, causing an apparent change in the heating level, the previous heating level display is maintained until a retainer timer counts up, preventing the display from flickering.

The power supply of the circuit 2a is shifted in the direction where the part in which the linear output range of the circuit 1 gets out of that of the circuit 2a is equal to 0. An an optimum shift extent is secured by obtaining coincidence between the linear areas of both circuits 1 and 2a so that the coincidence is secured between the linear areas serving as the buffer circuits. Thus the Vss' can be shifted to the Vss by -Vbp and the Vdd' can be shifted to the Vdd by -VBP respectively.
