1.新式活塞环 河南省鑫福集团公司新近研制成功一种能自动调节间隙的新式活塞环,已经国家内燃机监督检验中心等权威部门鉴定。该产品技术思路新颖,在攻克内燃机活塞环“早磨、漏油、漏气”百年顽症中取得了重大突破,具有节能、环保、增加动力和延长发动机使用寿命等突出特点。 “鑫福活塞环”把一个活塞环分成上下两片,它们之间以斜面拼对起来。在活塞的往复运动中,上下片受挤压而轮流伸缩,起到了与气缸壁自调间隙的作
1. New piston ring Henan Xin Fu Group successfully developed a new piston ring automatically adjust the gap, the National Internal Combustion Engine Supervision and Inspection Center and other authorities have been identified. The product has a novel technical concept and made major breakthroughs in tackling the chronic problem of internal combustion engine piston ring “early grinding, oil leakage and air leakage”. It has the outstanding features of energy conservation, environmental protection, increased power and prolonged engine life. “Xin Fu Piston Ring” to a piston ring is divided into two pieces, between them with a bevel fight together. In the reciprocating motion of the piston, the upper and lower pieces are squeezed and take turns retractable, played with the cylinder wall self-adjusting clearance for
