Intake/outlet pipe optimization method for rotary engine

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.

Description

CROSS-REFERENCE[0001]This application is a divisional application of a pending application Ser. No. 14 / 212,773 filed on Mar. 14, 2014, entitled “INTAKE OUTLET PIPE OPTIMIZATION METHOD FOR ROTARY ENGINE”.BACKGROUND OF THE INVENTION[0002]1. Field of Invention[0003]The present invention relates to an intake / outlet pipe optimization method for a rotary engine and an apparatus thereof, and particularly to the method and apparatus that control the length, diameter and shape of the intake pipe and outlet pipe, so that the pressure of the air pipes is corresponsive to the pressure of an air chamber of the engine to enhance the engine power.[0004]2. Description of Related Art[0005]In general, a conventional rotary engine has the advantages of high power-to-weight ratio, small volume, fewer components, and compact structure, and the intake and outlet pipes of the engine are smooth pipes The engine divides a cylinder into three air chambers by a triangular rotor. When the rotor rotates a round...

Benefits of technology

[0008]In view of the shortcomings of the prior art, it is a primary objective of the present invention to overcome the shortcomings by providing an intake / outlet pipe optimization method for a rotary engine, wherein the pressure wave in the intake pipe together with the pressure in the air chamber of the rotary engine are adequately adjusted by the appearance alternation of the intake / outlet pipe to improve the air intake status of the engine and enhance the performance. Without changing the design of engine body, the shape, length and diameter of the intake / outlet pipe can be adjusted. Compared with the conventional straight intake / outlet pipe, the shape of the intake pipe of the invention is tapered to adjust the pressure of the air pipe and increase the air intake, so as to enhance the engine power.

[0017]Through Different combinations of the pipe length, pipe diameter, and pipe shape described in the step (D) to adjust the amplitude and frequency of the pressure wave in the intake pipe in accordance with the instantaneous chamber pressure, the engine can be situated at a proper or better air intake status, and the mass of air intake will be increased to enhance the performance.

Problems solved by technology

Unlike a general piston engine that can control the intake and exhaust timing by adjusting the intake / exhaust valves to achieve an optimized status, the power output of the rotary engine is confined to the arrangement of its fixed geometric appearances and cannot be changed without hardware modification.

On the other hand, if the pressure is higher in the air chamber than the intake pipe, the air in the chamber will flow reversely into the intake pipe, meaning that the air intake process temporarily stops, or even more the air flows out from the intake pipe, and thus resulting in an insufficient air intake.

At present, most of the methods of enhancing the engine performance emphasizes on the appearance of the combustion chamber or the ignition timing, and thus incurring a higher cost and a longer time for modifying the engine body or using an additional turbocharger to provide a higher inlet pressure and a greater air intake to enhance the performance.

However, a too-high pressure in the intake pipe will increase the fuel consumption rate, and a portion of fuel gas is discharged from the outlet pipe, and thus failing to comply with the economic and environmental protection requirements.
