AI Technical Summary

Benefits of technology

The present invention is about a type of engine that has a piston and a head plug. The engine body has a chamber and a passage that lets fluid enter it. The piston moves back and forth in the chamber during engine operation. The head plug can be adjusted to change how tightly the engine is compressed. This invention helps create energy in a more efficient way.

Problems solved by technology

For instance, prior art poppet valve assemblies are mechanically complex and expensive to design and build.
Such valve assemblies require an extensive amount of cyclical operation that tends to wear and fatigue the components, including the poppet valves.
Also, heat from combustion also tends to exacerbate any wear or fatigue experienced by poppet valve assemblies.
Prior art engines with rotary valves are also deficient.
For instance, prior art rotary valves experience warping of the valve components due to uneven heating of the valve body.

Embodiment Construction

[0038]Turning initially to FIGS. 1 and 2, the reciprocating engine 30 is constructed in accordance with a preferred embodiment of the present invention. The illustrated engine 30 is preferably a four-cycle internal combustion engine (IC engine) including two cylinders 32 and 34 that receive corresponding pistons 36. However, the principles of the present invention are equally applicable for use with alternative cylinder configurations. For instance, the invention could be used in connection with single cylinder engines (not shown) or multiple-cylinder engines (also not shown). In the case of multiple-cylinder engines, such engines could have the cylinders arranged in more than one row (e.g., a V-8 engine).

[0039]The illustrated engine 30 preferably operates as a spark-ignition engine, such as a gasoline-powered engine. However, the principles of the present invention are applicable where features of the engine 30 are used as part of an alternatively fueled IC engine, such a diesel-po...

Abstract

A reciprocating engine includes an engine body presenting an internal chamber and a fluid intake that supplies intake fluid to the internal chamber. The engine also includes a piston that oscillates within the internal chamber during engine operation. The engine body includes a block and a head that form the internal chamber.

Description

RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 61 / 790,816, filed Mar. 15, 2013, entitled ROTARY VALVE ENGINE, which is hereby incorporated in its entirety by reference herein.BACKGROUND[0002]1. Field[0003]The present invention relates generally to reciprocating engines. More specifically, embodiments of the present invention concern an internal combustion engine with a rotary valve assembly to control intake and exhaust flow. Embodiments of the present invention also concern an internal combustion engine configured to provide a variable compression ratio.[0004]2. Discussion of Prior Art[0005]Conventional internal combustion engines include poppet valves to control intake flow into the cylinders and exhaust flow out of the cylinders. Such valves open and close by moving along the axis of the corresponding valve stems. The valve mechanism of conventional engines that use poppet valves also includes a cam shaft that engages the val...
