WORK-LIFE BAL­ANCE SHAFT

Torque (Singapore) - - CONTENTS - EDI­TOR DAVID TING davidt@sph.com.sg

Ac­cord­ing to Audi’s tech­nol­ogy por­tal, a pair of bal­ance shafts can elim­i­nate the free sec­ond-or­der in­er­tial forces that de­tract from the me­chan­i­cal smooth­ness of an in­line 4-cylin­der re­cip­ro­cat­ing en­gine.

The bal­ance shaft is lo­cated in the crank­case, car­ries coun­ter­weights and counter-ro­tates at twice the speed of the crankshaft. The bal­ance shaft brings bal­ance to the force of in­ter­nal com­bus­tion, so to speak. I could use one now to re­bal­ance my ed­i­to­ri­alengine ca­reer and my every­thing else.

Be­cause the os­cil­lat­ing mo­tion of the pis­tons in my head gives me a lane-split­ting headache, the con­nect­ing rods in my petrolpump­ing heart feel rather dis­con­nected and my cre­ative-think­ing crankpins seem cranky. At some point on the long, wind­ing and in­ter­est­ing road that took me from avid writer to angsty edi­tor, my oc­cu­pa­tion be­came my main pre­oc­cu­pa­tion.

Hope­fully, you’ll be sim­i­larly en­grossed when read­ing this well-bal­anced is­sue.
