Optimized diesel engines

In Mercedes-Benz passenger cars, the fourth generation of common-rail direct injection (CDI) adapts fuel injection even more precisely to various conditions of load and engine speed. The higher injection pressure increases the engine’s output and, thanks to its superior combustion, reduces raw emissions. The piezo injectors also match the fuel injection to the momentary driving situation.

This means lower levels of emission, fuel consumption, and noise. The four-cylinder CDI engine in the Mercedes E-Class develops 150 kW (204 hp) while only consuming 5.3 to 5.0 liters per 100 kilometers (fuel consumption, combined cycle)*. As compared to the predecessor model, this means a 20 percent higher output and 24 percent lower CO₂ emissions (CO₂ emissions, combined 139 - 130 g/km, energy efficiency class: A)*. The V6 turbodiesel unit, used for example in the Mercedes-Benz C 350 CDI BlueEFFICIENCY, in combination with the 7G-TRONIC PLUS automatic transmission and the ECO start / stop function offers superior output and torque: 195 kW (265 hp) and 620 Nm – with a combined consumption figure from 6.0 to 5.9 liters per 100 kilometers (CO₂ emissions combined: 157 - 154 g/km, energy efficiency class: C)*

The new CDI technology is also used in Daimler’s smallest vehicle: The current smart fortwo cdi has a combined fuel consumption figure of just 3.3 liters per100 kilometers, corresponding to CO₂ emissions of only 86 grams per kilometer. This agile city car thus defends its world-leading position as the CO₂ champion among vehicles with internal combustion engine.

The Fuso “6R10” engine complies with JP 09, currently the world’s most stringent emissions standard. This powerful engine is being used for the first time in Japan in the Fuso Super Great. All engines of the New Engine Generation (except the EPA 07) include BlueTec emission technology for a significant reduction in the emissions of nitrogen oxides, particulate matter, and CO2 – and are the same time highly economical.

The 6R10 for the Fuso Super Great, with a displacement of 12.8 liters and power outputs currently ranging from 257 kW (350 hp) to 338 kW (460 hp), is ideally suited to the customer requirements of the Japanese market.
In future, the New Engine Generation will also power Mercedes-Benz trucks. This already opens the door to maximum-efficiency combustion engines of the next generation, which in conjunction with BlueTec emission technology, exhaust gas recirculation, and a closed-loop diesel particulate filter will meet the Euro 6 standard.
