Though they remained influenced by de Havilland practice their products began to diverge and eventually contained original designs.〔〔 By the mid-1930s they had several four cylinder air-cooled inverted inline engines on offer, including the R.4L-02 displayed at the 1936 Paris Air Show.〔 Though it shared a name with a post-war model, the two engines were very different: the 1936 engine produced from about 4 litres and with a dry weight near ,〔〔 the later reached from 6.3 litres at a weight of .〔 During the Occupation of France and in the years shortly after World War II, Régnier designed and produced a set of three simplified four-cylinder inverted air-cooled inline engines of increasing capacity and power, the 4J, 4K and 4L. The specifications of the post-war 4L engine are similar, though not identical to, those of the pre-war R.4, whilst those of the pre-war R.4L specifications are closer to that of the post-war 4K.〔〔 In 1946〔 or 1947,〔 Régnier, now nationalised, was absorbed into SNECMA and the 4L engines, the most widely used member of the series,〔 became the SNECMA-Régnier 4L. Notable constructional features, shared with the 4J and 4K engines,〔 included machined steel cylinder barrels with external baked-on anti-corrosion varnish and separate cylinder heads with unusual metallo-plastic seals, held to the crankcase by long bolts. Screwed-in plug bushes and valve seats were made from aluminium-bronze. The 4L's five-bearing steel crankshaft was forged, as were the duralumin connecting rods which had split, steel backed, bronze bearings. The crankcase was cast from aluminium alloy.〔〔 SNECMA continued to produce the 4L series until at least 1956.〔 The most prolific type to use it was the military Nord NC.856A, with 112 examples.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SNECMA Régnier 4L」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
