For testing purposes, Volvo has fielded three FM trucks with Euro 5-compliant, 13.0-liter diesel engines that have been modified for LNG operation. Volvo's reasoning behind developing this complex system is actually quite simple. The company envisions a future where long-haul trucks operate on renewable biogas and biodiesel, which reduces our dependence on oil and lowers overall emissions. Lars Martensson, environmental director at Volvo Trucks, describes the importance of weening the world's vehicles off oil in this way:
Hit the jump for more on Volvo's field trial of the methane-diesel long-haul trucks.Increased use of gas is a bridge towards climate-neutral transports. Biogas production is already taking off in many countries. We're currently in a transition period, moving from decades of dependence on oil to a society built on renewable fuels. When trucks can operate on 80 percent pure biogas and 20 percent pure biodiesel, carbon emissions will be 80% lower than with conventional diesel technology.
