The most important facts you need to know about the urea (AdBlu) injection on modern diesel powered passenger cars in North America.
AdBlue is a liquid cleansing agent added to the Catalytic Reduction system of the Clean Diesel to further reduce emissions. A Clean Diesel engine with proper maintenance plus AdBlue, will produce ultra low emissions without compromising engine performance.
The AdBlue is mandatory in North America since, modern clean diesels have a particulate filter which is paired with the urea injection to reduce nitrous oxides. Nitrous Oxides (NOx emissions) are the trade marks of diesel combustion process.
Both manufacturers BMW and Mercedes has it in their fleet of high tech clean diesels to comply with the strict North American emission requirements. North American emission requirements has been government mandated.
The important fact is if your modern diesel automobile has a urea injection system then it needs to be replenished periodically. Otherwise you may not be able to restart your engine, once you turn it off and the add blue tank is empty.
The AdBlue urea is held in a separate onboard tank and fed into the metering module with a pump.
Average consumption of AdBlue is around 0.1 L/100 km, or 1 to 3 per cent of diesel consumption.
The system can't be fooled, it does check the liquid level and will test the quality of the fluid (the effectiveness that is). If there is water in the place of the AdBlue the engine may not restart and the vehicle may need to be towed to have the system reinitialized.
For that reason it's a wise thing to have some AdBlue on board just in case if you need it.
It's worth to mention the system designed to give you plenty of time before your car runs low in this vital fluid to the operation of your modern diesel engine with ultra low emissions.
Also worth to mention as well if you drive more spirited your reduction system will run longer and will effectively use more AdBlue fluid to keep the emission control system operating at maximum efficiency.
These are the need to know facts about your AdBlue emission reduction system on today's modern high performance diesel automobiles for a daily driver.
