一、引言 从1968年开始,博杜安发动机公司开始研制一种包括4缸、6缸、8缸和12缸等机型的新发动机系列。 该系列发动机的技术要求是: ——严格保证发动机持续运转时转速为3000转/分,以便与50赫兹的双极发电机匹配。 ——最大的单缸工作容积应与3000转/分的转速相适应。 ——该系列中从4缸机到12缸机都要尽量保持设计的一致性。尤其要有尽量多的通用部件,如单个气缸盖、连杆和活塞、配气机构、飞轮外壳及飞轮,发动机的前端面等。 ——可靠性高、寿命长和维修保养简便。曲轴等主要部件的使用期限要达到15000小时以上。
I. INTRODUCTION Beginning in 1968, Baudouin Engine Company started to develop a new series of engines including 4-cylinder, 6-cylinder, 8-cylinder and 12-cylinder models. The technical requirements for this series of engines are: - Strictly guarantee a speed of 3000 rpm for continuous engine operation to match a 50 Hz bipolar generator. - The largest single-cylinder working volume should be adapted to 3000 rpm. - In this series from 4-cylinder to 12-cylinder engine should try to maintain the consistency of the design. In particular, there should be as many common parts as possible, such as a single cylinder head, connecting rod and piston, valve train, flywheel housing and flywheel, front end of engine and so on. - High reliability, long life and easy maintenance. Crankshaft and other major components of the useful life of up to 15,000 hours or more.
