Engines that power JCB agricultural machinery will be recalibrated to meet Tier 4 Final emissions regulations while providing up to 5% more fuel efficiency. The manufacturer announced its strategy this week.
"We have continued to use innovative in-cylinder technology to reduce exhaust emissions within the JCB Ecomax engine, rather than relying on extensive aftertreatment," says Alan Tolley, director of engine programs at JCB Power Systems. "Through recalibration, and in some cases the addition of our one can SRC solution, we have delivered a range of technologically advanced engines that meet the requirements of Tier 4 Final within existing packaging requirements."
A compact selective catalytic reduction (SCR) solution with a urea-based additive will be used with engines above 74 hp. The system will be incorporated into a single exhaust muffler and use a 2% to 3% ratio of exhaust additive to fuel.
