Summary
A significant improvement of gasoline internal combustion engines is mandatory to meet the ever more stringent CO2 emissions limitations in various regions of the world. Water injection efficiently reduces combustion chamber temperatures, which opens a full panel of engine improvements, such as compression ratio increase, specific power output increase, engine and exhaust system protection. Additionally the emissions at engine start can be more easily managed.
In this paper, a study is made on how a water storage and delivery system can be designed to make it viable and acceptable for every day driving cycles across the world. It describes the introduction of a water injection in a compact high performance sports car, with limited available space. The challenge is to make such a compact system fit for all possible driving conditions.
