More specially, the disclosed system is designed to use to improve the combustion efficiency of the internal combustion engine (ICE) by using pure liquid oxygen.

BACKGROUND OF THE INVENTION

Transportation systems are a fundamental part of logistics and planning whenever vehicles are used to move people or items from one location to another. In current situation there are number of means are available in present transportation system. In other words, it can be said that these transportation systems are developed in a wide variety of sizes. Local transport networks spanning the bus network for a city and its suburbs are common, as are country-wide delivery networks for haulage firms. In every aspect human activity transportation is much important, without transportation it is impossible for humans to commute from one place to another and without commute they are not able to achieve their needful daily tasks. Therefore, transportation plays major role in life of humans. In transportation system number of users are rely on fossil fuel powered vehicles as the fuels used in it are easily available. Despite being a finite resource, it is available in plenty. These fuels are generating high amount of energy during combustion in which it can easily converted from chemical energy into mechanical energy by using internal combustion engine (ICE). Due to its various advantageous factors over the other fuels, it is more convenient for the usage.

The road transport sector is one of the largest consumers of commercial fuel energy within the transportation system in world and accounts for nearly one third part of the total liquid commercial fuel consumption by all sectors. Therefore, the usage of petroleum products and its derivatives which are derived from hydro carbons is increased and consumption for road transportation have quadrupled in last few decades due to about nine times increase in the number of vehicles and four-fold increase in freight and passenger travel demands. Therefore, to accomplish these demands high amount of fossil fuels are consumed by number of customers. As results, day by day the number of pollution levels increases in exponential manner and due to immense pollution, there is huge environmental degradation. By doing study and analysis on pollution and its impact on environment many researchers conclude that among all the sectors automotive sector is one of the major sectors contributing to the pollution, because the vehicles run on diesel and petrol and other alternative fuels as fuel produces exhaust gases after combustion which are hazardous for humans as well as environment. These vehicles contribute to pollution through various types of pollution like brake pollution, tyre pollution, particle pollution, toxic emission from engines etc.

With the rapid development of industrial technology and the continuous improvement of people's living standards, the number of various transportation vehicles has increased by leaps and bounds. Due to which it has negative impact on air quality and energy saving, because the engine generates harmful gases such as carbon dioxide, carbon monoxide, and hydrocarbons after combustion of fuel. In addition to that nitrogen oxide compounds, sulphur dioxide, and PM2.5 with fine dust which are all discharged into the air in large quantities, causing pollution to the environment, which is also one of the important reasons for the haze weather.

Therefore, to reduce pollution and to protect the environment the pollution control drive initiated across the globe which also provides boost to use of alternative fuels as well as more fuel-efficient systems to overcome the different types of pollution. At present, although various automobile and engine manufacturers have made great technological progress in energy saving and environmental protection. However, they are still not ideal in improving fuel combustion efficiency and due to the low fuel combustion efficiency, it is become an important factor that causes unsatisfactory exhaust emission indicators.

There are several or numerous attempts are made and different types of techniques are used by doing modification in existing technologies to improve the combustion efficiency and overall performance of the engine. By providing improved ignition system and providing larger throttle body or by providing high compression ration with much larger cylinder head performance of an internal combustion engine may be enhanced but these solutions are much costlier and it requires more design considerations of engine systems.
