Volvo trucks set to run on LNG and bio­gas

Australian Transport News - - News -

Liq­uid nat­u­ral gas and bio­gas is be­ing in­tro­duced to the lat­est Volvo trucks in or­der to bring them into line with Euro 6 com­pli­ance stan­dards.

The Volvo FH LNG and FM LNG will boast the same per­for­mance and fuel con­sump­tion of Volvo’s diesel-pow­ered trucks, the com­pany says.

Avail­able in 420hp ( 313kW) and 460hp ( 343kW), the trucks are ex­pected to re­sult in 20-100 per cent lower CO2 emis­sions, de­pend­ing on the choice of LNG or bio-LNG, ac­cord­ing to the man­u­fac­turer.

The trucks are pow­ered by gas en­gines util­is­ing diesel cy­cle tech­nol­ogy, rather than the Otto cy­cle typ­i­cally used for gas-pow­ered ve­hi­cles. The 460hp gas en­gine de­liv­ers max­i­mum torque of 2300Nm, with the 420hp ver­sion giv­ing 2100Nm.

Volvo di­rec­tor of en­vi­ron­ment and in­no­va­tion Lars Mårtens­son says both the cli­mate and bal­ance sheets will win with the new en­gines.

“We can now o er an al­ter­na­tive with low cli­mate im­pact that also meets high de­mands on per­for­mance, fuel e ciency and op­er­at­ing range,” Mårtens­son says.

“This is a com­bi­na­tion that our cus­tomers in re­gional and long haulage re­quire.”

Truck tanks are lled with LNG, with the big­gest fuel tank vari­ant con­tain­ing enough LNG for a range of up to 1000km. The fuel is warmed up, pres­surised and con­verted into gas while driv­ing, be­fore be­ing in­jected into the en­gine.

To ig­nite the gas, a small amount of diesel is added at the mo­ment of in­jec­tion.

While Aus­tralia has been slower to adopt LNG tech­nol­ogy, there is move­ment to­wards less re­liance on fos­sil fu­els that is likely to make al­ter­na­tives like LNG in­creas­ingly ap­peal­ing.

Volvo FM LNG and FH LNG truck sales will be­gin next year.
