John Deere's emissions solution

257 John Deere Power Systems says that its new PowerTech 13.5litre engine meets the Tier 4 Interim/Stage IIIB emissions legislation, along with the firm's latest 6.8litre and 9litre variants launched earlier. With this development the firm's entire engine range with power outputs of 130kW and over now meets the emissions requirements. The engine features the firm's proven PowerTech Plus Tier 3/Stage III A engine platform, which uses cooled exhaust gas recirculation (EGR) for NOx control and an exhaust filter for reducing particulates. The engine also has full-authority electronic controls, a four valve cylinder head, a high-pressure fuel system, series turbocharging and air-to-air aftercooling. It offers power ratings from 298-448kW.

Meanwhile the company has also developed a new JDLink telematics system available with the latest electronically controlled Tier 4 Interim/Stage IIIB off-highway diesel engines. The system features the latest generation of JDLink equipment monitoring and the new Service ADVISOR Remote program. These tools allow customers to monitor conditions and status of engines remotely, while also allowing technicians to perform engine diagnostics and some repairs.
