Construction and working

• Torque Multiplier • Higher power out put • Boost pressure

Turbo charger

Turbo charger Operation

COMPRESSOR SELECTING COMPRESSOR SIZE

SUPPORTING SYSTEM FOR TURBO CHARGER

OLING SYSTEM FOR TURBO CHAR

INTER COOLING FOR AN TURBO CHARGER

OOSING THE TYPE OF INTER-COO

•AIR/AIR INTEERCOOLER •AIR/WATER INTERCOOLER • AIR-TO-WATER INTERCOOLER

WATER SYSTEM FOR TURBO • WATER PUMPS • RESERVOIR • WATER INJECTOR

TURBOCHARGER LUBRICATION

SELECTING LUBRICATING OIL

• TYPES OF LUBRICANTS • WATER COOLED BEARING HOUSING • OIL FLOW PRESSURE REQUIREMENTS

These are good guidelines for virtually all turbo: Min. pressure (PSI) Min. flow(gal/min)   Idle hot Maximum load
