Clean engine

JCB Power Systems has developed a combustion system for the latest JCB Dieselmax engine, the JCB Ecomax T4 4.4 L. The solution eliminates the need for any exhaust aftertreatment and features reduced fuel consumption and improved reliability and packaging, according to the company. The Ecomax T4 meets Tier 4 Interim emissions standards without a DPF; cooled exhaust gas recirculation is used to clean up the gases before they are passed from the engine, eliminating the need for any exhaust aftertreatment components. JCB and Ricardo used CFD, FEA, and a combustion bowl to improve the process, and Delphi developed an electronic control system with a learning capacity to ensure the engine stays within its intended parameters even as components settle. Variable geometry turbochargers have been integrated on all but the 55 kW (74 hp) engine.
