PROPULSION FEATURE The hydrogen fuel cell is the most promising realistic electric technology for industrial applications such as long-haul transportation, says FPT's Annalisa Stupengo. prototype evolution of that engine, which should be on sale by 2020. The Cursor 13 NG Evo prototype uses a new cylinder head design with a pent-roof combustion chamber with tumble intake ports, designed for positive ignition combustion. The engine also benefits from a higher-pressure direct injection fuel system, to deliver reduced emissions during transient operation. A high-pressure cooled exhaust gas recirculation (EGR) system helps to reduce throttle losses at part load and a variable valve timing system with cam phaser technology works to achieve improved volumetric efficiency. TRUCK & OFF-HIGHWAY ENGINEERING FPT now has natural gas engines from 3.0- to 12.9-L capacity, delivering 134 to 460 hp, to suit light, medium and heavy commercial vehicle and bus applications. The engine's CO2 emission levels are said to be 9% lower than those of a similarly powered diesel engine, with a 98% cut in particulate matter and 48% lower NOx emissions. "Natural gas is the only green answer that is fully available now," said Stupengo. "It is a reality today in our on-road applications and will soon feature in offroad as well."
