Press Information 12 March 2015 Mercedes-Benz Diesel Engines: Top 10 Facts Mercedes-Benz has equipped its cars with special systems to reduce dieselparticulate emissions since the 124 series in 1988 – and in 1990 the first Mercedes-Benz was launched with an emission control system and exhaust gas recirculation to exceed even the stringent standards set in North America Today, Mercedes-Benz cars use Clean Diesel engines called ‘BlueTEC’ – and have done since 2006 – meaning they have consistently been among the most efficient, cleanest engines you can buy. They use a series of complex filters, each reducing exhaust emissions – both Nitrogen Oxide and particulates – bringing an end to the black soot associated with diesel engines The rate of efficiency gains has been relentless – five years ago, a C-Class (C 350 CDI) emitted 154 g/km of CO?. The equivalent model today, the C 300 BlueTEC Hybrid, emits 98 g/km of CO? All Mercedes-Benz diesel engines carrying the BlueTEC badge (excluding the E 300 BlueTEC Hybrid) use AdBlue? technology to help reduce the harmful nitrogen oxides found in the vehicles’ emissions. AdBlue? is a solution composed of urea and demineralised water – it is non-toxic, colourless and odourless. AdBlue? is injected into the engine’s exhaust gases by the BlueTEC system – resulting in a chemical reaction which converts the nitrogen oxide into harmless nitrogen and water vapour In the UK, over Mercedes-Benz 14,000 cars equipped with the AdBlue? system were registered last year Every new Mercedes-Benz car with a diesel engine is equipped with ECO start/stop, a system that automatically shuts down the engine when the car is at a standstill Diesel Particulate Filters (DPF) have been fitted to Mercedes-Benz cars since 2003 Mercedes-Benz offers a comprehensive choice of engines – including a range of petrol, diesel, petrol-electric Hybrid, diesel-electric Hybrid and fully electric cars Mercedes-Benz is adding to this choice with two new petrol-ele
