To meet the Tier 3 regulation, most engine manufacturers added an Exhaust gas recirculation (EGR) circuit to their engine to reduce the amount of oxygen in the combustion chamber. The answer is simple just check the SCR indicator light on your dash panel. However, DEF is reserved for their high-horsepower tractor equipment. That allows us to operate without regening. First, they need to be familiar with the systems their manufacturer has chosen to go with and the associated warnings and maintenance requirements those systems carry. interval but some manufacturers claiming the interval will be up to 15,000 hrs. When you get to the regeneration step is when it changes the way you can use the machine. The system requires diesel exhaust fluid, also known as DEF. Press Esc to cancel. The pros are better fuel economy, increased horsepower, more optimized combustion, fewer regenerations issues, less wear on the engine and in addition it only releases nitrogen and water vapor into the air.

MANUFACTURERS I think the ISB variant used in the Ram trucks was the last one to get DEF in all models and it was for the 2013 model year, but some Ram models changed over to DEF in 2011. :confused2::confused2: Its the same old story, played out now several times over. The new high-horsepower tractor engines that are equipped with SCR are programmed to stop working when your tractor runs out of DEF. For those not willing to accept the changes there has been a shift to olderused diesel engines or remanufactured diesel enginesthat have been grandfathered in. Sum of the smaller kubotas like some models in the l series still don't have them. Are the new engines higher installed cost, the reason Kubota didn't use them on their tractors? Then the exhaust travels to a Diesel Oxidation Catalyst (DOC) and diesel particulate filter (DPF) where the DOC further cleans particulate matter with increased heat while the DPF collects the remaining soot. And that year Winnebago still had a few non DEF chassis that they were allowed to build. In 2010 the regulations got even tighter.Many thought that the era of big power and torque were over and vowed to never purchase a new truck ever again. You must log in or register to reply here. New Holland tractors started using DEF in 2011 to meet governmental mission regulations.

EGR systems cool and combine certain amounts of exhaust with incoming fresh air (remember the saying, the solution to pollution is dilution) to lower combustion temperature and reduce nitrogen oxides to an acceptable level. EGR systems generally operate automatically but come with the worry of needing to override the regenerative process in enclosed areas such as a barn. That being said they may have been left over 2013 models, it made no difference to me I did not want the added garbage. That is pretty basic emissions technology but comes with complexity and cost. It's success lead to the creation of Kubota Tractor Corporation in California. 20 Facts You Need To Know About Diesel Exhaust Fluid (DEF) The Environmental Protection Agencywas created in the footsteps of the Clean Air Act of 1970.

I checked 9 tractor brands to find out whether they use DEF; which of their series use DEF and the year it was adapted. At 15% DEF tank level (Low), warning lamp is illuminated (solid yellow, Warning level 1), At 5% DEF Tank Level (Empty), warning lamp flashes yellow and Inducement Level 1 is initiated, After 45 Minutes of Level 1, Inducement Level 2 is initiated (flashing red DPF symbol + solid stop lamp), At 0% DEF Tank Level, the Tank has Leakage and Inducement Level 2 is initiated (probably already initiated), Inducement progressively reduces engine performance in stages, limiting useful work and motivating the operator to add DEF to the DEF tank, Once the tank is refilled, engine performance is restored. Usually the first digit of the date code represents the batch number and the next 6 digits reflect the date the batch was filled at the factory. The 1.1 percent increase in that example didnt sound all that bad, but the overall estimate for most nonroad categories was for a 1-3 percent hike. The DEF as part of the Selective Catalytic Reduction system (SCR) turns NOx into pure nitrogen and water vapor. TYM tractors built since 2010 are equipped with SCR and require DEF. However, most of these brands made by TYM are always treated independently. We have also compiled a list of the most popular manufactures of DEF here. Fuel mileage can be improved by as much as 5%-7%. For every 50 gallons of diesel fuel burned you will use 1 gallon of DEF. you think EGR is bad now just wait and see whats comming in 3-4 years. Like Marty and Diane, we've had no trouble with the system at all. Lastly, when DPF filters require servicing the removal of ash remember, the EPA and California Air Resources Board (CARB) have labeled the residue a hazardous waste. All new on-highway engines manufactured after. My 2011 Winnebago has a non-DEF 140 hp ISB engine. The high horsepower engines are equipped with the SCR and therefore can use DEF.

In an SCR system, the exhaust passes through a DPF or a combination of DPF and DOC first, then doused with a mist of water and urea commonly referred to as diesel exhaust fluid (DEF). DEF is closely regulated and has precise requirements for maintaining chemical purity and contains ingredients that are crucial to working in conjunction with the SCR system. Larger 2-5 gallon tanks usually have a small date code imprinted on the label of the product. This system uses a catalyst in the exhaust system of applicable diesel engines. I'm not too worried about egr. Since Kubota has announced that many of their midsize engines will be available without a Particulate filter next year does this mean that the current 60 series models will use those new engines when they are available? WARRANTY For example it would take over two years a constant rate of 125 degrees F for the DPF to turn into ammonia and evaporate.
