The DOC-only engine models complement an initial line-up of Tier 4 engines from Kubota that utilized diesel particulate filters (DPF). Skid Steers Rise to the Tier 4 Emissions Challenge If the engine is started for even a short time diesel fuel will ruin the SCR catalyst which is very costly to replace and will be out of warranty. This is the only practical way this brand employs to meet governmental regulations. 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). Mahindra has a new innovation that enables them to meet the stringent Tier 4 final standard without the use of SCR which uses DEF and DPF. What year did John Deere put DEF on tractors?

And even the ones that have adopted the changes do not apply it to all their high horsepower (hp) brand series. For example, the John Deere 7290R we tested last September now meets FT4 requirements using a combination of SCR, DOC, DPF and coded EGR technologies. Health studies are now focusing on what particle size is the primary cancer causer and new European standards specify limits on different particle sizes. 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. DEF requires a separate tank and delivery system. So when an engine company announces they are introducing a line of engines with a different configuration to meet customer demand, you need to know what that demand is.
