In this invention sleeve is used to improve the two stroke engine. It is a magic device which eliminate the use of mixing of lubricant in the fuel.

In this invention we provide the radial grooves and spherical grooves in place of washers which were used in prior TESLA TURBINE. The washers take sufficient space even then the discs tend to stretch, deform and vibrate. If number of washers increased the space decreased accordingly efficiency decreased. In the p...

A DAS turbine in which the fresh air enter and gained the heat energy from the burning gases under the boundary layer of DAS turbine in one or more sets.

In the present invention the tesia turbine is made with the material which is poor heat conductor. Due to poor heat conductivity the eddy currents does not formed which was responsible for poor torque and efficiency. In the present invention these drawbacks is abolished.

A two stroke internal combustion engine made with an exhaust valve near top dead center and inlet port bottom dead center which runs on any fuel used by conventional internal combustion engine.

According to figure 1 to 4: The main cone (5) is having angular slots (6) at the inner side. Big opening of the cone is closed by the cover plate (4). The main cone can rotate along with cover plate on the bearings (1) (2). When the charged fluid or steam enter through the pipe (8) in the inner cone which is not ...

In the present invention a single valve controls the suction stroke, compression stroke, power stroke and exhaust stroke. This valve having a cylinder attached with a conventional valve on one side. Cylinder having openings which are matching with the exhaust port during up and down motion. The conventional valve co...

In the present invention the testa turbine modified with boundary line separator. This separator improves the torque of tesia turbine which was the main drawback of prior tesia turbine. The main hindrance in commercialisation of tesia turbine is weak torque. In the present invention this hindrance abolished. ...
