Mercedes-Benz unveiled its roadmap for gasoline engine technology in India. "The CGI technology heralds a new era in gasoline engines with improved output, optimized consumption and even more impressive emission statistics" commented Prof. Dr.-Ing. Bharat Balasubramanian, Vice President Product Innovations & Process Technologies, Group Research & Advanced Engineering, Daimler AG, speaking to media persons at the launch event.
The CGI technology makes its debut in the C-Class. Dr. Wilfried Aulbur, Managing Director and CEO of Mercedes-Benz India explained the rationale: "The C-Class is in most cases the first touch point of customers with our brand. Mercedes-Benz stands for exciting products and cutting edge technologies; what better way to reinforce this promise than by offering the C 200 CGI as the harbinger of the CGI revolution in gasoline engines!"
The CGI technology is the first of its kind in the world to use sophisticated petrol direct-injection engine with spray guided combustion process. CGI engines use piezo-injectors (also seen on the global F700 DiesOtto concept presented by Daimler AG). With the new technology, the engine can run with high excess air and thus offer excellent fuel efficiency. Thanks to multiple injection, it is for the first time possible to extend this lean-burn operating mode to higher rpm and load ranges too.
Among the most important components of this innovative direct petrol injection system are the fast-acting piezoelectric injectors. They have nozzles which open outwards to create an annular gap just a few microns wide. This gap shapes the fuel jet and produces a uniform, hollow-cone-shaped spray pattern. The microsecond response times of the piezoelectric injectors provide the basis for delivering multiple injections per power stroke, and thus for lean-burn operation. By allowing flexible and efficient control of the combustion process they play a key part in ensuring the engine's outstanding fuel efficiency. The engine’s innovative injection procedure makes for much better fuel and thermodynamic efficiency than the wall-guided combustion process previously employed with direct injection.
Mercedes-Benz has replaced the previous 4-in-line KOMPRESSOR Technology with the world's first spray-guided direct petrol injection. Thus in the C-Class, the C 200CGI replaces the C 200 Kompressor in the model range. The C 200 CGI BlueEFFICIENCY equipped with the new engine technology consumes just 11.4 km /litres of fuel knocking 0.78 litres off the values of the C200Kompressor. CO2 emissions are also reduced from 215g/km to 201 g/km. The debutante offers an output of 137kW at 5600rpm (approx. 5% increase over the C 200Kompressor). At the same time it offers increased bottom-end torque of 285 Nm at 2400-4000 rpm (C 200Kompressor = 240 Nm @ 3500 - 4500rpm ). Thus the C 200CGI is keenly tuned in with the environmental objectives of lower emission at the same time becoming even more pleasurable to drive, more sporty and quick.
As well as an exciting design and hallmark Mercedes refinement, the Mercedes-Benz C-Class displays state-of-the-art technology such as the AGILITY CONTROL package with selective damper control and the PRE-SAFE system with anticipatory occupant-protection measures. Furthermore, independent studies confirm that the C-Class has the highest resale value in the medium-size category, while the latest breakdown statistics compiled by the ADAC (German Automobile Association) reveal that it is the most reliable car in its class.
The Mercedes-Benz C 200 CGI is priced at Rs. 26,25 Lacs Ex-showroom Mumbai. ( Ex Delhi is 28.98, Ex-Bangalore = 29.23 )
