摘要： PURPOSE:To freely inflate and float a float body in the air even indoors by blowing compressed air into an aperture from a hollow pole and floating the float body while inflating the float body to have a circular section. CONSTITUTION:A carp streamer 5 is formed out of nylon cloth as an example and has a mouth 5a as the aperture formed with a wire 13 having rigidity, such as piano wire, at its front end so as to be held open. A core bar 14 is disposed along a back part 5b in a part of the length of the body so that the weight of the carp streamer 5 itself can be supported. A flow regulator 18 is a flow regulating cylinder 19 made of a thin copper sheet. This flow regulating cylinder 19 is constituted to inflate the carp streamer by introducing air flowing in through the mouth 5a which is the aperture of the carp streamer 5 in the radial direction of the carp streamer 5. A supporting rod 6 is extended backard to generate a spacing 20 around the rod near the port 5a of the carp streamer 5 and is fixed and arranged to the supporting rod 21 in the vertical direction fixed to the supporting rod 6, to let the flowed-in air flow in the horizontal direction as shown by an arrow C.

摘要： PURPOSE:To promote mixture of air and fuel by a method wherein a re-entrant ring serving as a squish guard is protruded from the under surface of a cylinder head in a state to surround a fuel injection nozzle therewith and a compression flow is forced into collision with fuel spray through the gap of a cavity. CONSTITUTION:A re-entrant ring 2 is protruded from the under surface of a cylinder head 1 in a state to surround a fuel injection nozzle 3 therewith. A gap 7 is provided between the lip part 6 of a cavity 5 formed in the top surface of a piston 4 and the outer surface of the re-entrant ring 2. In which case, when the piston 4 is raised to a top dead center, a squish flow F1 is caused to flow through the gap 7 and injected in the cavity 5. The injection of the squish flow causes joining together of the squish flow F1 and a swirl flow F2 to promote a turbulence, improves mixture of it with fuel spray injected through the fuel injection nozzle 3 and in turn also causes improvement of NOx in exhaust gas.

摘要： PURPOSE:To enable high pressure injection without increasing a fuel injection pump side pressure by incorporating a constant residual pressure valve into a delivery valve of a fuel injection pump, and constituting an injection pipe of a taper pipe whose nozzle side is narrower than the other side. CONSTITUTION:A fuel injection nozzle 20 is connected to a pump unit 26 corresponding to a fuel injection pump 25 by means of a injection pipe 24. The fuel injection pump 25 is provided with a mechanical governor 27, and a control rack 28 is moved thereby, so that a supply quantity of fuel injected at one time is adjusted. In this fuel injection pump 25, a constant residual pressure valve 68 is incorporated particularly into a delivery valve 64 of the fuel injection pump 25, and the injection pipe 24 is also constituted of a taper pipe whose nozzle side is narrower than the other side. Thereby, high pressure injection can be attained without increasing lift of a cam 30 of the fuel injection pump 25.

摘要： PURPOSE:To restrain the generation of soot and black smoke by providing a conical bottom wall for a piston cavity, forming a down lip part in an opening, and shutting up flame in the piston cavity to the possible minimum level during a combustion process. CONSTITUTION:A piston cavity 4 formed inside of a piston is provided with a conical bottom wall 5 so as to possess an opening 3 on the top surface 2 of the piston 1. In the opening 3, a down lip part 7 is formed on a circular arc shape side wall 6 continuing to this conical bottom wall 5. The lip part 7 is constituted so as to shut up the flame in the piston cavity 4 to the possible minimum level during a combustion process. Thereby, since this flame is guided downward by means of the lip part 7, the flame can be shut up in the piston cavity to the possible minimum level during the combustion process. Thereby, situations such as the flame comes into contact with a comparatively low temperature part and generates soot and this causes black smoke and is discharged, can be prevented.
