Abstract

An intake/outlet pipe optimization method for a rotary engine, comprising the steps of: (A) providing a rotary engine; (B) providing a simulation software package, to perform a series of simulations for the rotary engine according to different combinations of a pipe length, a pipe diameter, a pipe shape and a pipe angle, to determine an optimal combination of the pipe length, the pipe diameter, the pipe shape, and pipe angle, to obtain an optimal power output for the rotary engine; and (C) performing tests for the rotary engine, by utilizing the optimal combination of the pipe length, the pipe diameter, the pipe shape, and pipe angle obtained in step (B), to obtain a test optimized power output for the rotary engine.

First claim

What is claimed is:

1. An intake/outlet pipe optimization method for a rotary engine, comprising the steps of:
(A) providing a rotary engine;
(B) providing a simulation software package, to perform a series of simulations for the rotary engine according to different combinations of a pipe length, a pipe diameter, a pipe shape and a pipe angle, to determine an optimal combination of the pipe length, the pipe diameter, the pipe shape, and pipe angle, to obtain an optimal power output for the rotary engine; and
(C) performing tests for the rotary engine, by utilizing the optimal combination of the pipe length, the pipe diameter, the pipe shape, and pipe angle obtained in step (B), to obtain a test optimized power output for the rotary engine.

2. The intake/outlet pipe optimization method for a rotary engine as claimed in claim 1 , wherein the simulation software package is a WAVE software product of Ricardo.

3. The intake/outlet pipe optimization method for a rotary engine as claimed in claim 1 , wherein since the pipe length, the pipe diameter, the pipe shape, and the pipe angle are varied simultaneously in combinations, the rotary engine is custom made into different sizes to fit into a limited space of an installation site depending on actual space limitations, and still providing optimized power output for the rotary engine.

4. The intake/outlet pipe optimization method for a rotary engine as claimed in claim 1 , wherein the pipe shape of the intake pipe is a tapered pipe shape, and the airflow direction is from the intake side with a relatively larger cross-sectional area to the engine side with a relatively smaller cross-sectional area.

5. The intake/outlet pipe optimization method for a rotary engine as claimed in claim 1 , wherein the pipe shape of the outlet pipe is a tapered pipe shape, and the airflow direction is from the engine side with a relatively larger cross-sectional area to the outlet side with a relatively smaller cross-sectional area.

6. The intake/outlet pipe optimization method for a rotary engine as claimed in claim 1 , wherein the pipe shape of the intake pipe and the pipe shape of the outlet pipe control the taper angle of the pipe, and the angle is an included angle between an open end of the pipe and the engine side.

7. The intake/outlet pipe optimization method for a rotary engine as claimed in claim 1 , wherein the pipe angle control range is from 0 degree to 50 degrees, and the pipe angles have values of a plurality of intervals in between.

8. The intake/outlet pipe optimization method for a rotary engine as claimed in claim 1 , wherein the pipe length control range is from 100 mm to 1500 mm, and the pipe length have values of a plurality of intervals in between.
