JCB EcoMax Tier4i engines made their North American debut at The Rental Show. These engines meet Tier 4 interim (Tier 4i) legislation through the use of patent-pending, in-cylinder technologies that offer a cleaner, more efficient combustion process. As a result of this technology, JCB meets the stringent Tier 4i emissions legislation without the use of diesel particulate filters (DPF) or after-treatments, such as Ad-Blue.
As well as the obvious environmental benefit from reduced emissions, the JCB Ecomax engine offers customers improved torque throughout the rev range, coupled with reduced fuel consumption. JCB Ecomax engines can run on standard engine oils, unlike engines with after-treatment solutions, which require a more expensive CJ4 oil to function correctly.
The “no after-treatment approach” also allows for an innovative recalibration option. This option allows JCB dealers to recalibrate the Ecomax engine to lower injection pressures and turn off the exhaust gas regeneration (EGR) function without any hardware changes. In effect, this recalibration takes the engine out of the EPA emissions tier system and opens it up for export to non-legislated countries that only offer lower quality fuels with higher sulphur content. This maximizes the residual value of used machines for customers and dealers alike without sacrificing the engine’s advanced features.
Because these engines do not require DPF or after-treatment, their dimensions and space claim on machines remain unchanged. This removes the need for any increase in chassis length or hood size maintaining the machines’ excellent maneuverability and visibility.
The JCB Ecomax engine range has been extended to meet the needs of machines spanning the 74 to 173 hp range, including Loadall telescopic handlers and rough-terrain forklifts.
