Internal steam engine

Abstract

An internal steam engine comprising one or more cylinders containing pistons, injectors and heating means. Air is drawn into said cavities and compressed as the piston reaches top dead center. The injector means spray the charge of heated compressed air with a non-combustible liquid which is vaporized under constant pressure followed by expansion and power stroke by the piston. The exhaust of the air mixture from the piston cavity is released through the liquid supply tank where the vapor is condensed and recycled to complete a closed operating cycle. A new charge is taken in at the end of the exhaust following either a four- or two-stroke engine process. The heating means are controlled by the cylinder temperature and activated to provide heat to the compression as required. In difference to a conventional steam engine, which generates steam from water in a boiler outside the working cylinder, the internal steam engine vaporizes water intermittently inside the working cylinder and exclusively in each compressed air charge to initiate a power stroke by the piston.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to two- and four-stroke internal combustion engines in which useful work is generated from combustion of oxidizer and fuel which expansion acts upon the top of an reciprocating piston. Such engines use either spark ignition or compression ignition for the combustion of the air-fuel mixture. The basic components of the engines include the engine block, cylinder head, cylinders, pistons, valves, crankshaft and flywheel. Such combustion engines are fueled by refined petroleum products and constitute the main power source for vehicle locomotion in the world today. The sheer quantity of oil being burnt for this purpose represent a growing threat to our environment by emission of carbon dioxide which, greenhouse gas, allegedly is the main contributor to the present trend of global warming. The world demand for oil also gives rise to geopolitical supply problems involving national security and economic instability. [0002] In ...

Benefits of technology

[0003] In summary, the internal steam engine injects a non-combustible liquid inside the mechanical structure and operational characteristics of the common diesel engine. In contrast to the diesel process, the steam power stroke is accomplished at lower operational temperature and without emission of noxious gases. In comparison with conventional steam engines, which gener
