Effect of Inject Spray Angle on the Cylinder - in 3D Flow Distribution of Diesel Engine
Abstract：The paper gives calculation on the inject spray and combustion process in the combustion chamber of the direct injection diesel engine using the CFD software , analyze the differences of cylinder - in 3D flow distribution and NOx emission and the calculation results in different inject angle. The results shows that air in the combustion chamber concave gets to be consumed much worse when the inject angle increases and the high temperature zone is much close to the cylinder wall and cylinder head surface. Reduction of inject spray angle causes increase of NOx emission and injector thermal load.
