To go more in-depth into JCB’s recent announcement of its “one-can” strategy for its Tier 4 Final EcoMax engines, I sat down with Alan Tolley, the manufacturer’s director of engine programs during the big Bauma 2013 show in Munich.
JCB says its Tier 4 Final approach builds on its Interim strategy, still staying away from the use of a diesel particulate filter and a diesel oxidation catalyst while introducing a selective catalytic reduction system on engines above 74 horsepower.
JCB is incorporating its SCR system into a single exhaust muffler, which it says can in many cases will replace the existing exhaust, giving the engines the compact dimensions desired by machine designers.
Watch Tolley’s comments in the video below.
