Tractors are used for a variety of tasks such as plowing, tilling, harvesting, and transporting goods. They are an essential tool in the farming and construction industry. In recent years, the US Environmental Protection Agency (EPA) has introduced new regulations that require diesel-powered tractors to use Diesel Exhaust Fluid (DEF) to reduce emissions. In this article, we will discuss what tractors require DEF and why it is important to use it.
What is DEF?
DEF, also known as AUS32, is a solution of 32.5% urea in deionized water that is used to reduce nitrogen oxide (NOx) emissions in diesel engines. It is a clear, non-toxic, and non-flammable liquid that is injected into the exhaust stream of a diesel engine. DEF is stored in a separate tank and is dosed automatically based on the engine's needs. DEF is consumed at a rate of approximately 2-3% of the diesel fuel consumed by the engine.
What tractors require DEF?
Tractors with diesel engines that are rated above 75 horsepower and were manufactured after January 1, 2014, require DEF. This includes tractors used in farming, construction, and industrial applications. DEF is required to meet the EPA's Tier 4 emissions standards, which require a reduction in NOx emissions by 90% compared to Tier 3 standards. Tractors that do not meet these standards are not allowed to be sold in the US.
Why is DEF important?
DEF is important because it helps to reduce NOx emissions from diesel engines, which are harmful to the environment and human health. NOx emissions can lead to the formation of smog, acid rain, and respiratory problems. By using DEF, diesel engines are able to operate more efficiently and emit fewer harmful pollutants into the air. DEF also helps to improve the lifespan of the engine, as it reduces the wear and tear caused by soot and other pollutants.
Conclusion
In conclusion, DEF is a necessary component for tractors with diesel engines rated above 75 horsepower that were manufactured after January 1, 2014. It is important to use DEF to reduce harmful NOx emissions, meet EPA standards, and improve engine performance and lifespan. As the farming and construction industry continues to grow, it is important to use environmentally responsible practices and technologies to reduce the impact on the environment.
