A New Innovative Direct Distributed Injection System of Fuel for Internal Combustion Engines

This paper is proving, via numerical simulation, that using the software program Fluent that the proposed Invention Patent is feasible as a viable solution to improve the combustion conditions inside the combustion chambers of internal combustion engines. The Romanian Invention Patent Number 123482 is protected according the International Laws. Fuel injection is a system for admitting fuel into an internal combustion engine. It has become the primary fuel delivery system used in automotive engines, having replaced carburetors during the 1980s and 1990s. A variety of injection systems have existed since the earliest usage of the internal combustion engine. The authors are proposing a new concept of a new Direct Distributed Injection System of Fuel for Combustion Engines. The fuel injection systems that exist and are deployed in practice have an essential shortcoming: the fuel is injected inside the cylinder using a single injector that disregarding the complexity, being placed in a central position, it cannot fill completely the combustion chamber and the mixture rates between fuel-air, due to the fact that the fuel droplets are leaving from a single central point, cannot collide one against other, so that the said fuel-air mixing rates are lower since the dimensions of the fuel droplets are relatively rough. The Invention is proposing a shift of the injection paradigm, instead of using one central injector to have in place an injection system which is leading to better colliding conditions of fuel droplets against each-other, with the end of a finer diameter of the resulting fuel droplets which in turn will lead to better combustion conditions.
