Thanks to development worth about $122 million, JCB’s Ecomax diesels won’t need a DPF to meet Tier 4 Interim limits. Twin Vortex combustion design jointly developed with Ricardo, and electronic controls from Delphi, are among new features. Its 4.4-liter and 4.8-liter model will use cooled EGR and second-generation common-rail high-pressure fuel injection.
