法国SEMT(Soci(?)t(?) d’Etudes deMachines Termiques)公司正进行一项试验研究:在不加大柴油机应力的情况下提高其容积功率。SEMT公司于1969年对柴油机进行第一次试验。增压器后空气被冷却到-30℃,柴油机功率提高了25～30%,但是由于扫气水蒸汽冻结、燃烧、柴油机体积大、冷却装置和干燥装置较复杂诸问题,影响了容积功率的进一步提高。目前SEMT公司在PA6系列四缸试验型样机上(4PA6)进行试验。PA6柴油机缸径280毫米,行程290毫米,压缩比ε为12.5,在
France SEMT (Société d’Etudes de Machines Termiques) is conducting a pilot study to increase its volumetric power without increasing the stress on the diesel engine. SEMT company in 1969 for the first test of the diesel engine. After booster air is cooled to -30 ℃, diesel engine power increased by 25 ~ 30%, but due to scavenging water vapor freezing, burning, large diesel engine, cooling devices and drying devices more complex problems affecting the volume power Further improve. SEMT company currently in the PA6 series of four-cylinder test prototype machine (4PA6) for testing. PA6 diesel engine bore 280 mm, stroke 290 mm, compression ratio ε 12.5
