The present invention provides internal combustion engines with double acting piston arrangement for improvement of power to weight ratio, which is an important metric to evaluate the performance of an internal combustion engine. Higher power to weight ratio reduces fuel consumption as the engine has to carry lesser weight of its own, making it more suitable in automobile and aircraft applications. In a double acting piston internal combustion engine, fuel is burnt twice by conducting power stroke on both sides of the double acting piston thus producing nearly twice as much power in same control volume.

It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
