Engine is a horizontal, single piston engine (1 on drawing) with power rods (2 on drawing) extending from the sides of the piston through the ends of the engine (although one rod may be used if desired for a special purpose). The ends of the engine are bolted to the flanged master cylinder. Piston has compression rings on each side with lubrication grooves circling the piston between the compression rings. At one end of the cylinder the water methanol and/or ethanol mix is injected via a electronic injector (5 on the drawing) along with the explosive gas or gasses and air mix via an electronically controlled valve (6 on the drawing). Note injector and valve are shown both above and below the cylinder for the purpose of demonstrating they may be located in various places as to the desire of the manufacturer and the purpose intended for the engine. The explosive gas or gasses are ignited via an electric spark from a source (7 on the drawing). Exploding gas converts the water/alcohol mix to steam vapor with the gas, steam, and alcohol powering the piston toward the other end of the cylinder. At the center of the engine the piston passes under an electronically controlled lubrication injector (8 on the drawing). A sensor trips the injector. Note the lubrication may either come from the top down or the bottom up depending on the size of the engine and the lubricant choice of the lubrication engineer. Opposite of the lubrication injector is an electronically controlled drain valve (8a on the drawing). The piston passes beyond the electronically controlled air injector (3 on the drawing) and the electronically controlled exhaust valve (4 on the drawing). When it passes the sensor for the air injector the air injector near the piston and the electronically controlled exhaust valve on the opposite end of the engine open. The cylinder area behind the piston is flooded with fresh air to condense the steam and hot gasses. This cools the engine and provides noise pollution control by creating a cooled (non expanding) gas to enter the exhaust pipe. The power cycle then repeats itself with the air injector closing prior to the piston return and the exhaust valve on the opposite end of the engine closing immediately before the arrival of the piston. Again, this is done via sensors embedded in the piston and the cylinder. Sequence control of the electronic injectors, valves, and input from sensors is per code developed and operated within computer chip and related components operating as the master electronic control.
On larger engines the exhaust valve may also drain out some lubricant which may be collected in a commercial oil/water separator then recycled while the cooled gas or gasses flow out through the exhaust system. The water may be recycled or pumped out as per the desires of the manufacturer. Lubrication of the power rods is as the lubrication of the piston with compression rings either located closely within the extension or connected to the power rod and separated by a distance equal to the journey of the piston. Multiple engines may be used as deemed necessary by the manufacturer of the product to be powered.
