Diesel exhaust fluid (DEF) is a harmless solution consists of 32.5 percent urea and 67.5 percent ionized water. It is a censorious component of SCR technology, which has been broadly received as the most effectual means to lessen NOx and meet outflow needs assigned by the EPA in its Tier 4 standards.
In order for the reactant conversion procedure to work accurately, fleets require to hold the DEF tanks on their vehicles top up the similar as they would for fuel. That DEF is then inserted into a vehicle’s exhaust stream, where it melt down harmful NOx outflow and turns them into nitrogen and water after burning. DEF consumption is approximately 2 percent of fuel consumption, but it can vary depend on such agents as load ratings, duty cycle, and functioning of vehicles, among others.
Cleanness and Contamination: Smart buying decisions are condemning to the positive result of any fleet. The purchase and usage of low-quality DEF can lead to notable results that are extra maintenance and rise in costs. If blended or contaminated DEF is utilised in a vehicle, the reactant converter in the DEF system can help the notable damage, leading to increase in recess.
Shelf Life: There is some argument as to the longevity of DEF and its level of usefulness as time moves on. While DEF’s urea in the end degrades, and the fluid itself decays into ammonia gas, DEF can be looked for to manage its effectiveness for more than a year. It is actually tough to get the DEF to a position where it won’t perform well within two years. To maximize its lastingness, however fleets should think about:
- Preserving DEF at room temperature.
- Stopping DEF from being lay bare to direct sunlight.
- Buying DEF housed in non transparent bottles, rather than clear bottles.
- Holding DEF from being lay bare to temperatures less than 12 degrees F.
- Putting the heating rods, insulation blankets and/or heating blankets around DEF tanks on a vehicle to fight cold temperatures.
Run Low: It is condemning for fleets to pay attention to the indicators that their vehicles are running low on DEF to make sure that they curtail the danger of downtime, keep away the extra repairs and hold their charges in check. Relying on the brand of engine in the vehicle deck out with SCR technology, particular warnings will acquaint with a driver if they require topping up the DEF tank. If the system does not have the accurate DEF, or runs out of DEF, the reduction procedure cannot take place as planned and out flowing of NOx will rise up.
It’s hard to have closed systems,” “If you acquire something else into DEF, a small bit will pollute quite a bit. That is why accurate and daily examining of DEF is such an essential practice for fleets. Ensure that it is what you consider it is.
