First four-cylinder BLUETEC model: well on the way to complying with the EURO 6 emission standard
Mercedes-Benz is unveiling its highly environmentally-compatible BLUETEC technologyin combination with a consumption-optimised four-cylinder engine for the first time at the 2007 Geneva Motor Show. In terms of ensuring compliance with the even stricterEURO 6 emission standard, applicable to all new vehicles Europe-wide from 2015, theMercedes-Benz Vision C 220 BLUETEC shows the way ahead. Boasting an output of 125 kW (170 hp) and a peak torque of 400 Nm, the Vision C 220 BLUETEC consumes 5.5 litres of diesel per hundred kilometres.
With the Vision C 220 BLUETEC, Mercedes-Benz is providing a taste of things to come as part of its BLUETEC initiative which was launched in the US last autumn.
The initial impetus came from the market launch of the E 320 BLUETEC in North America in October 2006, which was timed to coincide with the introduction of low-sulphur diesel in that part of the world. A fuel consumption figure of 6.7 litres per hundred kilometres makes the E 320 BLUETEC one of the most economical vehicles in its class in the US.
With the first four-cylinder BLUETEC model, Mercedes-Benz illustrates just how versatile this innovative technology can be. Following the US launch, Mercedes Benz will also introduce BLUETEC in other markets. The technology is currently being adapted to European market requirements and further Mercedes Benz models, the aim being to also offer BLUETEC for European customers, starting in 2008.
BLUETEC high-tech for the cleanest diesels in the world
BLUETEC is a Mercedes-Benz developed technology designed to effectively reduce diesel vehicle emissions, especially nitrogen oxides – the only exhaust-gas constituents that are still higher in diesel engines than they are in their petrol counterparts due to the design concept involved. One of the key requirements is to effectively minimize the nitrogen oxides before they are produced. This is why the Mercedes-Benz engine specialists focus on optimizing the engines and their combustion processes.
In terms of “hardware”, the sophisticated four-cylinder power plant in the Mercedes-Benz Vision C 220 BLUETEC, like the standard-production engines, includes four valves per cylinder, third-generation common-rail direct injection, a turbocharger with a variable nozzle turbine and exhaust gas recirculation. A highly sensitive electronic engine management unit reacts precisely to an extremely wide range of operating conditions and, in so doing, optimizes the combustion processes.
The BLUETEC technology in the Mercedes-Benz Vision C 220 BLUETEC still includes an oxidizing catalytic converter, which reduces emissions of carbon monoxide (CO) and unburned hydrocarbons (HC), as well as a particulate filter. A modified NOx storage catalytic converter with a substantially extended service life, including patented on-board ammonia generation, is combined with an additional SCR catalytic converter to minimize nitrogen oxides. This process of exhaust-gas after treatment requires no additives.
Mercedes-Benz Vision C 220 BLUETEC combines environmental awareness, driving enjoyment and comfort
The results are impressive whichever way you look at them: on the one hand, the concept car equipped with a 6-speed manual transmission consumes just 5.5 liters of diesel per hundred kilometers (NEDC 2000); on the other hand, it delivers the same impressive output and torque figures whilst providing a unique combination of efficiency and driving enjoyment. By way of example, the sprint from 0 to 100 km/h takes 8.5 seconds and the top speed is 229 km/h.
The Mercedes-Benz Vision C 220 BLUETEC is prepared for future emission standards, even the considerably more stringent limits imposed by EURO 6, which will apply to all new vehicles Europe-wide from September 1, 2015. For instance, particulate emissions must be reduced by a factor of five by the time the EURO 5 standard is introduced on January 1, 2011 whilst EURO 6 stipulates nitrogen oxide limits that are only around 30 percent of the current limits. All Mercedes-Benz diesel vehicles with a particulate filter fitted as standard already undercut the particulate limits that apply from 2011 onwards.
