• JCB Ecomax engines meet Tier 4 interim (or “Tier 4i”) legislation through the use of patent-pending, in-cylinder technologies that offer a cleaner, more efficient combustion process.
JCB machines featuring the company’s award-winning Ecomax engines — an innovative solution to Tier 4 interim emissions legislation — were on display for the first time in North America at the American Rental Association’s Rental Show in Las Vegas, Feb. 10-13, 2013.
JCB Ecomax engines meet Tier 4 interim (or “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 is the only leading equipment manufacturer in the world to have met the stringent Tier 4i emissions legislation without the use of diesel particulate filters (DPF) or after-treatments such as Ad-Blue– resulting in the world’s cleanest and most efficient off-highway engines.
The JCB Ecomax engine builds on the success of the company’s original Dieselmax engine. Ecomax retains the same key characteristics such as high torque at low engine revs, robustness and reliability as well as low noise and vibration. The engine was developed following a $126 million investment program, and it has undergone over 110,000 hours of testing across a range of diverse applications, machines and environments.
As well as the obvious environmental benefit from reduced emissions, the JCB Ecomax engine also offers customers improved torque throughout the rev range, coupled with noticeably 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 74hp to 173hp range, including JCB backhoe loaders, Loadall telescopic handlers, wheel loaders, the TM range of telescopic boom wheeled loaders, JS excavators, rough terrain forklifts and skid steer loaders.
