Across 4. Turbocharger that drives the crankshaft 5. Colours you find on components that have been overheated 7. assembly comprised of turbine shaft and compressor wheel 8. dots on turbine shaft caused by hot shut downs 10. Oil holes are beveled to aid oil flow and prevent contaminants from shavings 11. This cools cleans and lubricates the turbocharger 13. valve that prevents turbocharger slowing on the closing of the throttle valve 14. Function of turbocharging that adds power 16. The point of fuel injection in a diesel engine 18. Seperate Circuit After Cooler 21. engine driven compressor 22. Bore size is larger than the stroke length 23. Oils internal resistance to flow 25. Used to increase air density 26. The filter that protects the engine in the event of a primary air filter failure 28. This device controls turbocharger shaft speed by diverting exhaust around the turbine 29. Twisting force on the crankshaft 31. Efficiency of using the fuels heat energy 32. Promotes a chemical reaction but is not used up in the reaction 33. The tendency of a body at rest to stay at rest or if in motion to stay in motion 34. Turbocharger bearings rotate in the housing, they are ___________ Bearings 36. Damaging rattling noise from the engine ( spontaneous combustion) 37. Manifold pressure above atmospheric pressure

Down 1. Total cylinder volume devided by residual volume 2. Bottom Dead Centre 3. Turbocharger arrangement that has a low pressure turbo feeding a smaller high pressure turbo 6. Jacket Water After Cooler 7. Compressor wheel that changes the direction of the air through 90 degrees 9. The turbocharger component that is driven by the turbine 12. The efficiency with which you fill the cylinder on the intake stroke 15. Top dead centre 17. uses water to measure pressure differential 19. Wear caused by contaminants in the oil 20. This drive dampens out crankshaft speed variation 24. Function of turbocharging that allow for engine operation at altitude 25. Welding process that uses friction to fuse the components 27. Intake and exhaust valve open at the same time Valve __________ 30. Piston movement from TDC to BDC 31. The exhaust drives this component 35. Bearing that controls axial play
