IVECO announce that they have combined with Boral to test compressed natural gas powered cement mixers.
In a fleet of 170 trucks most of which are IVECO Acco 2350G 8×4 diesel units, Boral has been testing five CNG powered trucks for the past six months with great success, mostly operating out of its Penrith, Preston and Liverpool sites.
The standard diesel trucks are IVECO Acco 2350G models running 6 cylinder, 8.3 litre Cummins ISC engines producing 285HP and 800 ft lbs torque at 2200rpm. The twin-steer front axles are Dana I140-S type with a capacity of 12.7 tonnes. Rear suspension is Hendrickson HN402 rubber block type with a capacity of 18 tonnes. Transmissions are Allison WT-MD3560P, 6-speed automatics.
The five CNG powered trucks are fitted with 6 cylinder, 8.3 litre Cummins C Gas Plus engines developed in conjunction with Cummins Westport of Canada. Derived from diesels, these spark ignition engines with a compression ratio of 10:1 produce 280HP and 850 ft lbs of torque.
These are 3rd generation CNG engines featuring multi-point sequential lean-burn induction technology and state-of-the-art electronic engine management. The result is a high performance, very clean running, perfectly reliable engine ‘straight out of the box’ that requires no further tinkering or tuning. Testing conducted by Cummins indicates that theses engines exceed ADR 80/02 emission standards, subject to official certification. They are a marked improvement over the 2nd generation electro-mechanical induction CNG engines.
