摘要

After the successful introduction of the 2,2-L ECOTEC engine with gasoline direct injection in 2003 for use in Opel vehicles, General Motors now introduces the 2.0-L ECOTEC turbo engine with direct injection and dual continuously variable cam phasing in the Model Year 2007 Pontiac Solstice GXP. These technologies help the ECOTEC engine produce more power with excellent response, while maintaining the lower fuel consumption of a small displacement port-injected engine. Producing 260 SAE horsepower (~194 kW) and 260 lb.-ft. (~350 Nm) of torque, the engine is GM's highest specific output production engine ever and is the most powerful production engine in the ECOTEC family. The engine is GM's first direct injection offering in North America. The engine was developed with the global resources of GM Powertrain in the United States and Europe, drawing on expertise from the naturally aspirated ECOTEC direct-injection and dual continuously variable cam-phased engines and turbocharged engines already in production.

(〜350 Nm)的扭矩,这是通用汽车有史以来最高的单位输出量生产发动机,也是ECOTEC系列中最强大的生产发动机。该发动机是通用汽车在北美的首个直接喷射产品。该发动机是利用美国和欧洲的GM动力总成的全球资源开发的,并利用了已在生产中的自然吸气ECOTEC直接喷射,双连续可变凸轮相发动机和涡轮增压发动机的专业知识。
