Abstract This paperwork provides via numerical simulation using the software Fluent, the Invention Patent that it is feasible as a viable solution to improve the combustion conditions inside the combustion chambers of the internal combustion Engines. The paper proposes a new concept of the 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, cannot fill completely the combustion chamber, so that the fuel-air mixing rates are lower since the dimensions of the fuel droplets are relatively rough. The Invention proposes a shift of the injection paradigm, thus instead of using one central injector to have an injection system which leads to better colliding conditions of the fuel droplets against each-other, with the end of a finer diameter of the resulting fuel droplets which will lead to better combustion conditions. Keywords: Fuel injection, internal combustion engines, direct distributed injection system, numerical simulation; * ADDRESS FOR CORRESPONDENCE: Liviu Constantin Stan, Constanta Maritime University, 104 Mircea cel Batran street, Constanta 900663, Romania, E-mail address: liviustan14@yahoo.com/ Tel.: +0-040-755156939
