ENERGY STUDY OF A 4STROKE, 4-CYLINDER, SPARK-IGNITION INTERNAL COMBUSTION ENGINE

Abstract
Abstract – The present work is an energy study of a 4-stroke, 4-cylinder, spark-ignition internal combustion engine. First, we swept all that is related to engines in general, then we focused on spark ignition engines, their architecture, their operating systems in parallel with other ancillary systems. In the analytical part, the different relations of the parameters of a Renault 19 1.4D engine have been cited. In the numerical part, we tried to calculate all the parameters of this engine. Finally, a graphical comparison was made between the yields in the theoretical case and the real case. Keywords - Energy Study - Spark Ignition Engine - Efficiency.
