Focus On Emissions Off-Highway Diesel Engines Promoting clean air, fluid efficiency, and engine performance

John Deere takes a focused approach to fluid efficiency and engine performance. In this guide, you’ll learn about engine emissions and how John Deere is meeting emissions requirements while maximizing performance, uptime, and efficiency. John Deere engines operate efficiently using ultra-low sulfur diesel as well as biodiesel blends. Biodiesel is an oxygenated fuel made from a variety of agricultural resources such as soybeans or rapeseeds. For more information about biodiesel, consult your engine operator’s manual, contact your local John Deere engine distributor or equipment dealer, or...

Understanding engine emissions A small but real challenge Regulations require off-highway engine manufacturers to remove almost all emissions pollutants such as nitrogen oxides (NOx), carbon monoxide (CO), hydrocarbons (HC), and particulate matter (PM). Most remaining engine exhaust is made up of elements commonly found in the air like nitrogen (N2), oxygen (O2), and water vapor (H2O). Engine exhaust is primarily made up of the following elements 99.7% Products of complete combustion N2 – Nitrogen O 2 – Oxygen CO 2 – Carbon dioxide H2O – Water NOx – Nitrogen oxides, caused by high...

More choices for meeting worldwide emissions regulations John Deere PowerTech diesel oxidation catalyst/selective catalytic reduction (DOC/SCR) engines join our complete lineup to give OEMs more choices for meeting Final Tier 4/ Stage IV emissions regulations. We continue to provide diesel oxidation catalyst/diesel particulate filter/selective catalytic reduction (DOC/DPF/SCR) engines, which deliver premium performance when the job requires it and are ready to meet Stage V regulations in the EU. We also offer a full line of Tier 3/Stage III A, Interim Tier 4/Stage III B, and engines...

As of 2019, the countries highlighted on this map require diesel engines to meet emissions requirements. Check with your regulatory agency for specific emissions regulations.

EPA nonroad emissions regulations *In the 50 to 74 horsepower category there are two options. Option 1 requires a reduced PM level (0.30 vs. 0.40) but allows Final Tier 4 to be delayed one year (2013). NOTE: The vertical dashed lines separating the years show when the seven-year life of the Tier 2/3 Equipment Flexibility Provision ends and engines can no longer be placed in vehicle production. John Deere engines comply with the two major nonroad emissions regulations — the U.S. Environmental Protection Agency (EPA) and the European Union (EU). We also provide engine configurations that are...

Emissions technologies John Deere uses a combination of innovative engine designs and new technology to meet varying application and emissions requirements around the world. Air-to-air aftercooled Air-to-air aftercooling not only reduces NOx, it allows increased low-speed torque and improved engine durability. It is the most efficient method of cooling intake air to help reduce engine emissions while maintaining low-speed torque, transient response time, and peak torque. Turbocharged Fixed geometry turbocharger Fixed geometry turbochargers are sized for a specific power range to maximize...

Fuel injection systems Exhaust filters High-pressure common-rail (HPCR) fuel injection system Diesel oxidation catalyst (DOC) The high-pressure common-rail fuel system provides constant control over fuel injection variables such as pressure, timing, duration, and multiple injections. The DOC reacts with exhaust gases to reduce carbon monoxide, hydrocarbons, and some particulate matter (PM). Diesel particulate filter (DPF) – Stage V ready Exhaust filters are used to reduce particulate matter. John Deere engines with DPF technology are Stage V ready. The engine industry expects that Stage V...

Emissions technologies Diesel engines can be configured to produce less NOx or less PM, but not at the same time. That’s why John Deere gives you a choice of two Final Tier 4 engine and aftertreatment configurations to best fit the needs of your application. JOHN DEERE EPA FINAL TIER 4 SOLUTIONS Engines that produce less NOx during combustion require the use of an exhaust filter to treat the increased PM, but also provide greater DEF efficiency that allows the use of a smaller DEF tank. Engines that produce less PM during combustion meet Final Tier 4 regulations without a DPF, but consume...
