Driver safety re­view

NT News - Motoring - - NEWS -

THE Na­tional Trans­port Com­mis­sion wants feed­back on driver safety pro­pos­als.

They are in a draft doc­u­ment re­leased un­der the As­sess­ing Fit­ness to Drive Com­mer­cial and Pri­vate Ve­hi­cle Driv­ers ( AFTD) pro­gram.

Pub­lished by Aus­troads and the NTC, the AFTD doc­u­ment out­lines na­tional med­i­cal stan­dards for driver li­cens­ing.

NTC safety se­nior man­ager Jeff Pot­ter said the re­vised doc­u­ment cov­ered the as­sess­ment of driv­ers and their abil­i­ties.

‘‘The pub­li­ca­tion has been im­proved to fo­cus on how the symp­toms of a per­son’s con­di­tion may af­fect their driv­ing rather than just the di­ag­no­sis,’’ Dr Pot­ter said.

The draft doc­u­ment is avail­able at JCB said it has cre­ated the world’s clean­est offhigh­way en­gine us­ing a new emis­sion re­duc­tion sys­tem.

De­vel­oped by Bri­tish en­gi­neer­ing firm Ri­cardo, the Twin Vor­tex Com­bus­tion Sys­tem en­ables the elim­i­na­tion of ex­haust af­ter treat­ment, pro­vid­ing an op­tion for off-high­way op­er­a­tors.

It uses a re-en­trant com­bus­tion-bowl de­sign with in­jec­tor-noz­zle ge­om­e­try which work with cooled ex­haust-gas re­cir­cu­la­tion, high air-fuel ra­tio and in­jec­tor pres­sures as well as elec­tri­cal ac­tu­a­tors for the ex­haust and air-man­age­ment sys­tems.

The technology will make its de­but in the new JCB Eco­max T4 en­gine.

Ri­cardo global diesel prod­uct group di­rec­tor Ian Penny said the sys­tem was a break­through in clean offhigh­way en­gine power and that trucks could ben­e­fit from it.
