一种将废气涡轮增压推进一步的节油发动机——废气涡轮复合式发动机,目前正在瑞典斯堪尼亚技术中心进行试验。这种发动机除具有常规的废气涡轮增压器外,在排气管内还装有一个燃气轮机。该发动机以斯堪尼亚牌柴油机(11L,262kW)为基础研制的,其功率可达294kW,而比油耗却降低了10g/(kW·h)。在研制的 An energy-saving engine-exhaust gas turbocompound engine that takes the turbocharger further forward is currently being tested at the Scania Technical Center in Sweden. In addition to the conventional exhaust turbocharger, the engine is equipped with a gas turbine in the exhaust pipe. The engine was developed on the basis of a Scania diesel engine (11L, 262kW) with a power of 294kW and a fuel consumption reduction of 10g / (kW · h). Under development
