JCB Ready For Stage 5
By Ian Cameron07 June 2019
JCB Power Systems will use a combination of next-generation particulate control technology, incorporating a diesel oxidation catalyst (DOC), integrated diesel particulates filter (DPF) and selective catalytic reduction (SCR) to meet European Stage 5 emissions regulations.
The new standards came into force on January 1, 2019 for engines below 56 kW and above 130kW. They take effect a year later on January 1, 2020 for engines in the 56-129 kW range.
JCB Stage 5 engines have been designed to fit beneath existing engine canopies, so they will not require redesign of machinery to accommodate the additional hardware and will not negatively impact visibility from the cab, the company said.
JCB’s three litre Dieselmax engine is rated at 55 kW with a maximum torque of 440Nm. It powers JCB’s backhoe loaders, Loadall telescopic handlers and other mid-range machines. It features a compact after-treatment system comprising JCB’s particulate control technology and auto-stop which shuts down the engine after a period of idling to minimise fuel consumption, said JCB.
The Stage 5 version of the 4.8 L EcoMAX engine, which powers JCB Loadall telescopic handlers, mid-range wheeled loading shovels and the larger TM telescopic wheeled loaders, produces 81-129kW and has peak torque outputs from 516Nm to 690Nm.
It features the compact after-treatment system comprising JCB’s particulate control technology with an SCR urea injection system for NOx reduction, and benefits from the adoption of a wastegate turbocharger and auto-stop technology that shuts down the engine after a period of idling to minimise fuel consumption.
