The Dispersion of the Heat Flow in the Engine Compartment. Case Study on Ford Fiesta 1.4i

Abstract

This paper presents a study concerning the influence of the dispersion of the heat upon the air filter and the intake manifold. The data was registered in real time with the help of thermo imaging camera at different operating regimes, route and traffic installed on a FORD Fiesta car, equipped with a gasoline engine with a cylindrical capacity of 1.4l. The propeller group is mounted transversely, a front constructive solution. The gas circulation is a inline cross flow type with the intake manifold placed in front of the engine and the exhaust manifold behind the engine. The air circulation through the air filter is a loop flow type having the in/out port orientated towards the front of the vehicle. This study wants to determine the influence of the materials which were used for the construction of the air filter and of the intake manifold upon the performance of the internal combustion engine. The results obtained after the tests allow us to determine the optimum parameters on the efficiency of the heat transfer.
