新型0.9 L 2缸增压汽油机是Fiat动力传动技术公司发动机开发的重要里程碑。被命名为“Twinair”的汽油机是极度小型化的杰出代表,不仅其总排量被减小,而且气缸数也减少了。通过废气涡轮增压与Multiair可变气门机构相结合,达到了出众的发动机功率,即相当于排量比其大50%的自然吸气发动机的功率,而且至少节油25%,废气排放满足目前实施的欧5排放标准。此外,Twinair 2缸汽油机的整个系统是按欧6排放标准要求设计的。由于采取了全面的优化措施,其噪声-振动-平顺性性能也成了小排量发动机的新标杆。
The new 0.9 L 2-cylinder supercharged gasoline engine is a key milestone in Fiat Drivetrain’s engine development. The petrol engine, named “Twinair”, is an outstanding example of extreme miniaturization not only with its overall displacement reduced but also with fewer cylinders. Combined with Multiair variable valve train through exhaust gas turbocharger, superior engine power is achieved, which is equivalent to naturally aspirated engine with 50% displacement and at least 25% more fuel economy, exhaust emissions meet the current Implementation of the EU 5 emission standards. In addition, the entire system of the Twinair 2-cylinder gasoline engine is designed to meet Euro 6 emission standards. Due to the comprehensive optimization measures, the noise-vibration-ride comfort has become a new benchmark for small displacement engines.
