摘要： A compression-ignition "split-cycle" engine (100) comprises: a cylinder block (200) with an expansion cylinder (6) having an expansion piston (7) that is adapted to move alternatively between a top dead center (ETDC) and a bottom dead center (EBDC) by a crankshaft mechanism (20) that causes a predetermined position of the expansion piston (7) to correspond to a predetermined crankshaft angle; a compression cylinder (2) having a compression piston (1 ) that is adapted to move alternatively between a CTDC and a CBDC according to a predetermined angular phase shift in delay to the expansion piston (7); a cylinder head (30) that closes the cylinders and comprises a crossover passageway (5) with an opening (5a) in constant communication towards compression cylinder (2) and an opening (5b) having a transfer valve (4) towards expansion cylinder (6), an intake valve (3) and a exhaust valve (9); a means for opening/closing the transfer valve (4); a means for opening/closing exhaust valve (9) at predetermined moments of the alternative cycle of the pistons, and a fuel injector (8) in the crossover passageway (5). The opening movement of the transfer valve (4) is carried out in advance 20° or more of crankshaft angle with respect to the crankshaft angle of the ETDC, such that from the opening instant up to reaching the ETDC there is a substantial equalization of pressure between the cylinders, such that between the ETDC and the CTDC a transfer occurs of the comburent fluid between the two cylinders, and such that injector (8) injects the fuel (8a) starting from the achievement of the ETDC.
摘要翻译：一种压燃式“分段循环”发动机（100）包括：具有膨胀缸（6）的缸体（200），所述膨胀缸具有膨胀活塞（7），所述膨胀活塞适于在上死点（ETDC）和通过使所述膨胀活塞（7）的预定位置对应于预定曲轴角度的曲轴机构（20）产生下止点（EBDC）; 具有压缩活塞（1）的压缩缸（2），所述压缩缸适于根据到所述膨胀活塞（7）的延迟的预定角度相移而在CTDC和CBDC之间交替地移动; 汽缸盖（30），所述汽缸盖关闭所述汽缸且包括具有朝向压缩汽缸（2）持续连通的开口（5a）的交叉通道（5）和具有朝向膨胀汽缸（4）的转换阀（4）的开口（5b） 6），进气门（3）和排气门（9）; 一个用于打开/关闭转换阀（4）的装置; 用于在活塞的替代循环的预定时刻打开/关闭排气阀（9）的装置和位于交叉通道（5）中的燃料喷射器（8）。转换阀（4）的打开运动相对于ETDC的曲轴角度预先进行20°或更大的曲轴角度，使得从打开时刻开始到达ETDC，压力的基本均衡使得在ETDC和CTDC之间发生在两个气缸之间的燃烧流体的转移，并且使得喷射器（8）从实现ETDC开始喷射燃料（8a）。
