Operator presence system that warns if the operator is out of the seat while operating key functions. ComfortCommand™ seat with air suspension, lumbar support, swivel, fore-aft and lateral attenuation, backrest angle adjustment, adjustable left-hand armrest, and 40-degree right-hand seat swivel. The standard CommandView III cab offers unsurpassed visibility, operator comfort, control placement, and ride and sound quality. The following diagrams illustrate how air flows through the engine (PSS).įor added performance and efficiency, the engine passes the exhaust gases through an EGR cooler before it enters the engine. The gases mix with the rest of the incoming air from the turbocharger and aftercooler before entering the cylinders. In addition, EGR allows for advanced timing, leading to optimal performance of the engine, maximizing fuel economy.Įxhaust airflow enters into the EGR cooler from the exhaust manifold near the turbocharger.īased on engine load, air temperatures, and rpm, the ECU opens or closes the EGR valve, allowing a measured percentage of exhaust gas to enter the intake manifold. Replacing excess oxygen with cooled exhaust gas leads to lower combustion temperatures, creating less NOx. The EGR valve, in conjunction with the venturi and ECU, allows a controlled amount of exhaust gas to enter the intake manifold to mix with the incoming fresh air. Higher pressures created by our Final Tier 4 (FT4)/Stage IV high-pressure fuel system extend intervals between automatic cleanings.ĮGR reduces the high temperatures where nitrogen oxide (NOx) compounds are formed in the engine cylinders by replacing excess oxygen with a prescribed amount of cooled exhaust gas.Įxhaust gases contain more carbon dioxide than oxygen. 
In most cases, filter cleaning does not impact machine operation or require operator involvement. If natural filter cleaning cannot be achieved based on temperature, load, and speed, then particulate matter (PM) must be removed using an automatic cleaning process sometimes referred to as active regeneration. The engine control unit (ECU) and exhaust temperature management (ETM) system work together to continuously regenerate the exhaust filter using a natural cleaning process sometimes referred to as passive regeneration. The John Deere exhaust filter is integrated into the engine design and electronics to provide a seamless operator experience.
