For over a decade, John Deere engines have been a core part of environmental sustainability strategy for Atlas Copco, a manufacturer of a full line of gen-sets and portable air compressors.
Most recently they partnered on three new air compressor models that meet Final Tier 4/Stage IV emissions standards.
“John Deere took a building-block approach in the development of emissions technologies over the years,” said Mark MacInnis, engineering manager at Atlas Copco. “It was gradual, rather than throwing a lot of new technology to the user all at once. For an OEM, it makes engine integration from tier to tier straightforward.”
John Deere Final Tier 4/Stage IV technology is ideal for our new air compressor solutions,” MacInnis said. “Selective Catalytic Reduction (SCR) used in tandem with EGR is the best approach to reducing nitrogen oxides (NOx). SCR and DPF collectively provide better transient response time compared to solutions that do not use a DPF.” In addition, he adds that John Deere Final Tier 4/Stage IV engines will use less DEF than competitive engines on the market, and he estimates that for every 100 gallons of fuel burned, the compressors will consume about 3 gallons or less of DEF. This new compressor model will also have enough fuel capacity to run 10 hours under full load. “This is important in remote, stationary applications where the ability to refuel will be limited,” McInnis says.
While adapting to accommodate Final Tier 4/Stage IV emissions was an ongoing process, McInnis was confident that partnering with John Deere will continue to be an asset for future product enhancements. “It’s been proven in the past and we’ve had good durability throughout the tiers, and I don’t expect that to change.”
