Fastener Design Manual

by

Summary

This manual was written for design engineers to enable them to. choose appropriate fasteners for their designs.Subject matter includes fastener material selection, platings, lubricants,corrosion,locking methods,washers,inserts,thread types and classes,fatigue loading,and fastener torque.A section on design criteria covers the derivation of torque formulas,loads on a fastener group,combining simultaneous shear and tension loads,pullout load for tapped holes,grip length,head styles,and fastener strengths.The second half of this manual presents general guidelines and selection criteria for rivets and lock bolts.

Crankcase Pressure Control In An Internal Combustion Engine: Gt-Power Simulation

by

ABSTRACT

The crankcase ventilation system is a very important part of the internal combustion engine but not so much attention is usually paid on what happens in the crankcase. A lot of information is available on what happens in the combustion chamber but not so many papers have been published related to the crankcase ventilation. Actually, efficiency improvements can be obtained with an optimization of the crankcase ventilation system and so fuel can be saved and the overall emissions of reduced.

The present is a thesis describing the work done by the author in his internship with Chrysler LLC during the Joint Master Degree program between Politecnico di Torino and University of Windsor.

The work is aimed to simulate the crankcase ventilation system of Pentastar V6 3.6L engine with a 1D/CFD software to see possible ways of improvement and provide some baseline guidance in the initial selection of design parameters for future engines.
