日本采用AR燃烧技术的二冲程发动机

Japanese 2-stroke Engine Adapting AR Combustion Technique

AR燃烧是能有效防止不利扫气的低速范围内易引起缺火的技术,简单地说,就是未燃混合气不只是依靠火花塞点燃,还有部分靠自燃燃烧促进扫气和减少HC。AR燃烧发动机可有效地增宽二冲程发动机致命弱点的低速扭矩,AR技术不适用于小排量摩托车发动机。

AR combustion technique is one enabling effectively to avoid misfire happening in low speed range. which is not favorable to scavenging, that is, the unburned mixed fuel will be ignited not only by the spark plug, but also (part of the fuel) by self-combustion . which can improve scavenging and reduce HC. AR combustion engine is able to effectively widen the low-speed torque of 2-stroke enging. But AR technique does not fit small-displacement motorcycle engine.
