Abstract: An intake/outlet pipe optimization method includes the steps of providing a rotary engine, measuring the pressure in an operation of the engine, designing the appearance of the intake/outlet pipes, adjusting the pressure wave in an air pipe and the pressure in an air chamber of the engine to increase the air intake and improve the output horsepower of the engine. The intake pipe is a tapered pipe having the pipe diameter on an intake side greater than the pipe diameter on the engine side; and the outlet pipe is an inversely tapered pipe having the pipe diameter on the engine side smaller than the pipe diameter on the outlet side.

Abstract: A micro jet gas film generation apparatus aims to eject a gas to a work object which is desired for cooling or insulating from heat. The micro jet gas film generation apparatus has a spout formed at a diameter of 5-100 μm to generate a gas film on the work object. As the diameter of the spout of the micro jet gas film generation apparatus is small, the micro jet gas film generated from the spout cannot produce a large eddy due to the lack of sufficient energy, hence can maintain a thin film after a long distance ejection to improve cooling and heat insulation performance. Moreover, due to the small diameter of the spout, it also consumes less gas and can reduce the amount of gas required.
