Embodiment Construction

[0099]The present invention is a novel rotary engine construction having at least one rotor and at least one rotating combustor fluid control device (CCFC) whose rotation is synchronized with the rotation of each rotor. Two stationary buffer seals are located at both ends of the short axis of the rotor housing and divide the latter into two separate spaces, a first intake and compression chamber and a second expansion and exhaust chamber downstream of the first space. Each CCFC receives compressed oxygen-containing fluid from the intake chamber, injects fuel into the compressed fluid, ignites the air-fuel mixture, and delivers combustion products to the expansion chamber.

[0100] To understand the utility of the engine structure of the present invention, first see Figure 1-3 , which shows several drawbacks of prior art Wankelfa rotary engines.

[0101] figure 1 There is shown a typical prior art Wankel rotary engine, generally indicated by reference numeral 10, comprising:...

Abstract

An improved rotary engine system has two stationary buffer seals located at the two ends of the minor axis of a rotor housing that divide the rotor housing into two separate volumes. A first volume is an intake and compression volume and a second volume downstream to the first volume is an expansion and exhaust volume. A rotating combustion chamber flow control device (CCFC) is synchronized with a rotor, for receiving compressed fluid from the first volume, for receiving fuel injected by a fuel injector located within a corresponding CCFC, for igniting and burning an air-fuel mixture, to allow combustion products to expand in the second volume, and for transferring the combustion products to the second volume. In one embodiment, the CCFC is synchronized with two longitudinal shafts fitted at centers of first and second housings, respectively, in each of which are located a pair of side by side rotors.

Description

technical field [0001] The present invention generally relates to rotary engines. In particular, the present invention relates to improvements in the Wankel engine and similar rotary engines which, when applied to prior art engines, effectively increase their power output and efficiency and enable higher cycles. Background technique [0002] The manufacturers of the Wankel rotary engine attempted to provide an internal combustion engine that would overcome most of the disadvantages of the reciprocating piston engine, while at the same time running smoothly, having a higher power-to-weight ratio and being more efficient than the reciprocating piston engine. High rotation speed. After many years of development, the Wankel engine, despite its theoretical advantages over reciprocating piston engines, several practical limitations prevented its widespread acceptance. Consequently, only a limited number of manufacturers were involved in Wankel engine production. [0003] figur...
