AbstractIn-cylinder flow field structure in an internal
combustion (I.C) engine has a major influence on the combustion,
emission and performance characteristics. Fluid enters the
combustion chamber of an I.C engine through the intake manifold
with high velocity. Then the kinetic energy of the fluid resulting in
turbulence causes rapid mixing of fuel and air, if the fuel is injected
directly into the cylinder. With optimal turbulence, better mixing of
fuel and air is possible which leads to effective combustion. A good
knowledge of the flow field inside the cylinder of an I.C
engine is very much essential for optimization of the design
of the combustion chamber for better performance especially
in modern I.C engines like gasoline direct injection (GDI),
homogeneous charge compression ignition (HCCI)
engines.The main objective of this work is to study the incylinder
fluid flow field characteristics of a single-cylinder
engine to see the effect of intake manifold inclination at
equivalent rated engine speed using Particle Image
Velocimetry (PIV) under various static intake valve lift
conditions. To facilitate the PIV experiments, the metal cylinder of
the engine was replaced by a transparent one. For every operating
test condition, 50 image pairs were captured and processed using
DAVIS software. From the results, it is seen that the in-cylinder
flow structure is greatly influenced by the intake manifold
inclinations irrespective of intake valve lift. Maximum Turbulent
Kinetic Energy (TKE) was highest at full intake valve lift
irrespective of the inclination. Also, the maximum TKE was
the highest for 600 intake manifold inclination compared to
other inclinations irrespective of the intake valve lift at
equivalent rated engine speed. Finally, it is concluding that
the analysis carried in this work is useful in predicting the
flow and inturn optimizing combustion chamber of modern
I.C engines. 德国LaVision PIV/PLIF粒子成像测速场仪 汽车发动机多参量测试系统 Imager LX PIV相机
