Development of Cost Effective Non-Permeable and Leak-Proof Air Inlet System Ducting for Turbocharged Intercooled Modern Diesel Engine 2012-01-0959
The modern trend of engine downsizing for CO₂ reduction coupled
with stringent emission norms compel the engine air inlet system to
outperform the conventional designs. Modern turbo diesel engine air
inlet system handles higher & higher air flow, boost pressure
Air inlet system ducting designs have become complex due to oil
particles (received through PCV system), engine movement and
isolation for NVH.
Air inlet ducting failures; like oil mist leakage through joints
and seepage through hose wall cause high engine oil consumption and
most predominantly environment damage. Also to some extent boost
leakage in certain operating conditions. These failures reduce the
reliability and performance of engine in certain conditions.
This paper discusses design and development of cost-effective
non-permeable and leak-proof hose-piping system for turbocharged
diesel engine where PCV system was connected to air inlet system.
Different materials of hose, different types of clamp and oil mist
separators were selected to make various configurations for
testing. The configurations were made to pass through static and
dynamic tests. At the end final configuration was determined which
met cost, performance & reliability targets.
