Description

内加热发动机 技术领域
本发明属于节能减排技术领域，具体是涉及一种内加热发动机。
 背景技术
斯特林发动机是英国物理学家罗巴特斯特林于 1816 年发明的。是通过气缸内冷却、压缩、吸热、膨胀为一个周期的循环来输出动力，斯特林发动机是一种外燃发动机。其有效效率一般介于汽油机与柴油机之间。其优点 1 、适用于各种能源，燃料。尤其适合工业余热利用。 2 、噪音小。 3 、不受气压影响。缺点 1 、热量损失大。 2 、体积大功率小。 3 、反应慢。目前已在航天、海洋、太阳能等各个领域少量的应用。很多热衷于和从事低炭环保研究人员做出利用斯特林发动机对工业余热、发动机排气余热进行回收利用的方案，由于目前斯特林发动机的缺点还不能有效地利用和推广。
本发明目的是利用降低碳排放的热能转化成电能。是通过改变斯特林发动机的外加热方式，提供一种内加热发动机。
本发明保留了斯特林发动机的所有优点，改善了热损失大，功率小，热效率低，起动慢的缺点。提供一种在热缸内加热做功方式的发动机。改变斯特林式发动机外加热方式，在热缸内设置固定加热功能的设施和在移动的活塞上设置加热功能的设施，启动时热缸内的固定加热设施和移动的活塞加热设施同时加热散热，推动活塞输出动力。通过气缸内冷却、压缩、吸热、膨胀为一个周期的循环来输出动力。目前斯特林发动机的活塞多用中空多隔层隔热方式，不能加热还有热损失。本发明利用加热活塞方式，使热缸内加热面积增加，相比同类体量型号的斯特林发动机能获得更多的热量，产生更大的功率。热缸内设有隔热保温装置，热量损失会减小。双向同时加热升温速度快，启动时间也会缩短。
本发明目的是充分利用工业余热、发动机排气余热接入所述发动机的固定加热设施和移动活塞加热设施，在热缸内加热推动活塞驱动所述发动机输出动力。还可以利用多种燃料在热缸内的固定加热设施和移动的活塞加热设施中设置燃烧装置燃烧加热，驱动所述发动机运行。
