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