Internal Detonation Reciprocating Engine

Abstract

A method of rotating a crank shaft and in internal detonation engine are provided. The internal detonation engine comprises a deflagration to detonation transition section. The deflagration to detonation transition section is connected to a main cylinder, which houses a piston. Inducing a detonation wave from the deflagration wave and passing the detonation wave through a fluid, gives rise to high pressure and temperature in a cylinder and pushes a piston towards bottom dead center. An internal detonation reciprocating engine may be a single cylinder and may be either a two or four stroke engine. A two-stroke internal detonation reciprocating engine is similar to a four-stroke internal detonation reciprocating engine but has different valve placements. Detonations produce a more thorough combustion of the fuel and may, thereby, yield reduced emissions of carbon monoxide as compared to internal combustion engines.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to the field of reciprocating internal combustion engines. More particularly, the present invention relates to internal detonation reciprocating engines.BACKGROUND OF THE INVENTION[0002]A reciprocating engine, a piston engine, converts heat to mechanical energy. One or more pistons convert pressure into a rotating motion. A fuel-air mixture is introduced and ignited inside a cylinder, which houses a piston. Upon ignition, the hot gases expand, pushing the piston to the bottom of the cylinder. Piston recovery, return to the top of a cylinder, is achieved via either a flywheel or from the movement of additional pistons connected to a same shaft. The expanded gases are removed from the cylinder, exhausted by this stroke. The linear piston motion is converted to rotating motion via a connecting rod and a crankshaft. Increasing the number of combined pistons on a shaft yields a greater piston displacement volume and in t...

AI Technical Summary

Benefits of technology

[0007]It is well known that detonation is a more efficient form of combustion than the slow speed deflagration process that is employed in internal combustion engines. Detonation releases more energy than deflagration and causes the burnt products to have higher temperatures, pressures, and densities. In turn, more work may be derived from these products. Further, pulsed detonation combustion generates less entropy than an equivalent deflagration process.

[0014]An internal detonation reciprocating engine, according to the present invention, increases the efficiency of conventional internal combustion reciprocating engines.

Problems solved by technology

Diesel engines, making use of higher compression ratios, yield higher efficiencies than internal combustion reciprocating engines but still do not approach 55 percent.
