JCB Tier 4 Final Engine Strategy Simplifies Maintenance and Resale | Construction News


The unique design of  JCB’s Tier 4 Final engines simplifies maintenance and allows easier resale.

Engines over 74 hp meet stringent Tier 4 Final emissions legislation by using a compact, highly efficient SCR system for NOx reduction, but need no diesel particulate filter (DPF).

Engines less than 74 hp require no DPF and no SCR system, thanks to JCB’s efficient combustion technology that handles emissions within the engine combustion chamber.

 JCB Tier 4 Final engines over 74 hp offer:

  • Up to a 5% fuel efficiency improvement
  • A compact ‘one-can’ SCR exhaust solution
  • The ability to be de-emissionized for sale into less regulated areas.

JCB’s Tier 4 Final engines 74 hp and lower feature:

  • No DPF required
  • No SCR/DEF required
  • The ability to be de-emissionized for sale into less regulated areas.

Fewer replacement parts and service requirements on all engines mean fewer hassles between rentals, yielding higher rental utilization rates and a greater overall return on investment.

JCB’s Tier 4 Final engine packages can be installed in existing machinery without bulky alterations to the body, ensuring that machines retain excellent all-around visibility and easy service access.

It is possible to de-emissionize the Tier 4 Final range, to allow machines to be re-sold into less-regulated territories.

All JCB dealers worldwide will have the technology to remove the SCR kit, reduce fuel-injection pressures, and recalibrate engine controls to de-emissionize the EcoMax engines, changes that the U.S. EPA says can be made only after a machine has left the country.

A lubricity dosing filter may need to be added in some countries, depending on the quality of local fuel.

“We have continued to use innovative in-cylinder technology to reduce exhaust emissions within the JCB EcoMax engine, rather than relying on extensive after-treatment,” said Alan Tolley, director of engine programs at JCB Power Systems.  "Through recalibration and the addition of our one-can SCR solution, we have delivered a range of technologically advanced engines that meet the requirements of Tier 4 Final within existing packaging requirements."
