Mercedes launched new C 200 CGI in India

Mercedes-Benz today launched its new C 200 CGI model in India with gasoline engine technology. “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.
