What does BlueTEC mean on a Mercedes?
selective catalytic reduction
BlueTec is Mercedes’ brand name for its system of selective catalytic reduction (SCR) or, in English, treating the exhaust gas of a diesel engine to reduce its emissions. So, a BlueTec car has the spray system, and a non-BlueTec car does’t.
What kind of engine does a Mercedes BlueTec have?
The heart of Mercedes diesel cars like the E320 BLUETEC is a 3.0-liter V6 turbodiesel engine. The engine has four valves per cylinder and each fuel injector is located at the center of the top of the combustion chamber, in the same location where most four-valve gasoline engines locate the spark plug, for optimum fuel burn.
What is the BlueTec system on an e320?
The BLUETEC system has a number of components that “scrub” the exhaust before it is released into the atmosphere. Two variants of the BLUETEC system exist, the NAC+SCR system and the AdBlue system. NAC+SCR is used on the 45-State version of the E320.
How does the Mercedes BlueTec exhaust system work?
AdBlue was introduced in the 2008 model year and sold in all 50 states. Exhaust leaves the engine and passes through a Diesel Oxidation Catalyst (DOC), which reduces carbon monoxide and unburned hydrocarbons in the exhaust.
What kind of heater does Bluetec diesel use?
DEF heater is another known weak points. All Bluetec vehicles use Diesel exhaust fluid, also known as AdBlue. It is stored in an external tank, and it would freeze in cold weather. To prevent this, DEF tank is equipped with an electric heater which can burn out.
Which is better Mercedes Benz E350 or E320 Bluetec?
High-tech diesel offers superior torque and fuel economy for $1000 more than an E350. There is a lot to appreciate about the new 2007 Mercedes-Benz E320 BlueTec.
What kind of engine does the Mercedes BlueTec have?
There is a lot to appreciate about the new 2007 Mercedes-Benz E320 BlueTec. For starters, it is powered by a technologically advanced 3.0-liter turbo-diesel V-6 that utilizes a sophisticated network of exhaust gas treatment devices that make the BlueTec the “world’s cleanest diesel,” according to Mercedes-Benz.
AdBlue was introduced in the 2008 model year and sold in all 50 states. Exhaust leaves the engine and passes through a Diesel Oxidation Catalyst (DOC), which reduces carbon monoxide and unburned hydrocarbons in the exhaust.
How does the Mercedes BlueTec particulate filter system work?
The AdBlue system houses the DOC and the particulate filter in a single housing. In addition to the NAC catalyst, ammonia is supplied by injecting a fluid called AdBlue into the exhaust upstream of the SCR catalyst. The addition of AdBlue fluid enables the SCR catalyst to reduce NOx emissions to a level even lower than the NAC-SCR system.
