Worldwide, research is going on numerous types of engines that practice green and alternative energy such as natural gas engines, hydrogen engines, and electric engines. One of the possible alternatives is the air powered car. Air is abundantly available and can be effortlessly compressed to higher pressure at a very low cost. After the successful development of Compressed Air Engines, engineers shifted their focus in making this technology cost effective and feasible. This led to advancement in the field of pneumatics that is advanced Compressed Air Engine Kit (used for conversion of a small-two stroke SI engine to Compressed Air Engine) where its frugality and compatibility is kept at high priority. This research is in continuation with our previous project of development of an advanced Compressed Air Engine kit and optimisation of injection angle and injector nozzle area for maximum performance.

Increased demand and use of fossil fuels in transportation sector accompanied by the global oil crisis does not support sustainable development for the future generations to come. Not only that, today's on-road vehicles produce over one third of the CO and NOX present in our atmosphere and over twenty per cent of the global warming pollution. This air pollution carries significant risks for human health and the environment. Through clean vehicle and fuel technologies, it is possible to significantly reduce air pollution from our vehicles. In such a grim situation, Compressed Air Vehicles (CAV) powered by pressurized air stored in high pressure storage tanks seem to be one of the practical solutions available for tackling the fuel crisis and environment related issues.
