Analysis of a Turbocharged Diesel Engine Progress Report 2 11/5/09 Jenelle Pope

Background

Project Steps Installation Check Out Compressor – air flow rate Radiator – sizing of heat exchanger Intercooler – sizing Selection of components Next Steps –Instrumentation Locations –Power Increase – based on airflow –Heat Exchanger Area

Turbocharger installed in engine Turbocharger fits where the old one did Brackets and oil lines fit Turbocharger runs with engine

Turbo Compressor Airflow out of the compressor, mass flow CFM = airflow rate CID = cubic inch displacement = 395 RPM = revolutions per minute = 2000 VE = volumetric efficiency = 80% Correcting for a boost pressure of 18psi:

Radiator Calculations Owner define –Cost –Size (dimensions) Surface Area, U Overall heat transfer, U

Intercooler Calculations Same as radiator Different flow rates and temps

Heat Exchanger Selections Unknown value for U Unknown value for A Discussion with manufacturer Feasibility: –Cost –Size (dimensions)

IntercoolerRadiator

Next Steps Instrumentation Locations –Inlets/outlets of heat exchangers Increased Engine Power –Based on airflow Validate Heat Exchanger Selections –Includes estimate on fin area based on actual measurements –Fit checks –Tube routing
