Abstract
In order to acquire considerable performances of Diesel engine admission´s routes, a mathematical example was drawn up, based on the finite element technique, which is specialized in two phases: liquid gas in 2D, modularly settled. Each module presents one of the processes supported by the fuel inside the intake manifold. In this work, the author intend to draw up a mathematical example in order to describe the procedures supported by liquid particle to the admission pipe´s wall of a Diesel engine.
Keywords: Diesel engine, mathematical example, fuel, intake manifold, liquid particle.
