JCB has a ‘one can’ solution for Tier 4 Final.
Using highly efficient combustion technology, the 4.4litre and 4.8litre Ecomax engines meet the required standards without the use of a diesel particulate filter (DPF).
JCB’s Ecomax engines have also been recalibrated for Tier 4 Final, resulting in a further 5% fuel saving compared to previous models.
A compact selective catalytic reduction (SCR) solution with a urea-based additive will be used on engines above 55kW. The SCR catalyst is incorporated into a single exhaust silencer, in most cases replacing the existing exhaust box, to provide a ‘one can’ solution.
It is a solution that remains compact, posing no further problems to install in a wide variety of machines without costly modifications to bodywork.
The range also includes four-cylinder Ecomax engines for industrial power units and G-Drive installations for generators and portable power equipment.
JCB said these engines have been specifically designed for the US market to meet EPA requirements, and lower Tier variants are available for less regulated markets.
