An Introduction
This is a closed type steam engine. Water and Oil has to be poured in to the closed operating cylinder of this Engine. When it is heated, in between the boiling point of water and smoking point of oil, the oil gets converted into heat transfer fluid and the water gets converted into working fluid, which enables the engine to get activated.
Parts and Figures
This Engine will function in four stages viz., heating, expansion, cooling and contraction
Heating
In this stage, the wet steam absorbs the heat from the surface of the hot oil and converts it into Dry steam.

Expansion

In this stage, the dry steam gets expanded. The expanded dry steam pushes the power piston upwards. As the result, flywheel rotates. Simultaneously, by the movement of flywheel, the Displacer piston moves downwards and replaces the expanded dry steam into cooler.
Cooling

In this stage, Dry steam looses it’s heat in the cooler and gets itself converted into wet steam.
Contraction

In this stage, the wet steam gets contracted. As a result, the power piston moves downwards and so flywheel rotates. Simultaneously, by the movement of flywheel, the Displacer piston moves upwards and replaces the contracted wet steam on the hot oil surface.
In all these four stages, the same steam recycles itself in the closed operating cylinder and activates the engine.
Analysis
By using final temperature of fluids formula and steam table, to convert an open type engine having 18 hp, into a closed type steam engine, the input energy required for working fluid(steam) and heat transfer fluid(oil) will be 1 hp. After subtracting the input energy (1 hp) from the output energy (18 hp), the balance OUTPUT GAIN(17 hp) can be utilized for the functioning of the vehicle or generation of electricity. The engine can also be started with the help of inverter battery.
