[#1] 直六回歸, 估佢唔到, 係.. ...賓士 http://www.autoblog.com/2016/10/31/2017-mercedes-benz-new-engines-inline-six-cylinder/ Mercedes-Benz unveiled four new engines, including a gasoline-powered 3.0-liter inline-six, a diesel variant of the 3.0-liter inline-six, a 4.0-liter twin-turbocharged V8, and a twin-turbocharged 2.0-liter four-cylinder. The gas-powered inline-six and the new V8 will power the 2017 S-Class when it gets its facelift, while the automaker is still figuring out where to place the other motors. Mercedes confirmed to Autoblog that the new V8 will be sold in the upcoming S-Class in the US, but the automaker doesn't plan to sell a four-cylinder S-Class here. The inline-six engines are a return to form for Mercedes as the automaker offered the engine layout in its vehicles until the late '90s. Dubbed M256, the 3.0-liter engine was built with the intention of electrification in mind and, therefore, comes with an Integrated Starter-Alternator (ISG), an electric auxiliary compressor, and intelligent turbocharging. These components allow the engine to make more power than the old V6 engine while also being more fuel-efficient. The M256 makes 408 horsepower and over 368 pound-feet of torque, while the older M276 V6 engine was good for 333 horsepower and 354 pound-feet of torque. A worthwhile improvement. 新turbo有個0.3秒 70000rpm 電子輔助増壓, 起機..冇turbo-lag! 其實即係而家F1 1600 turbo 嘅MGU-H 技術一部份? The turbocharger, ISG, and electric auxiliary compressor all work together to save fuel and reduce turbo lag. The ISG handles the majority of the work when the vehicle sets off, the electric auxiliary compressor fills in the gap until the larger turbo kicks in, and the new turbocharger spools up to ridiculous speeds – 70,000 rpm – within one third of a second. The ISG is part of a 48V electrical system that also handles the car's water pump and air-conditioning compressor, which makes drive belts irrelevant and reduces the overall length of the engine. |
