一种多缸柴油机供油提前角的调整装置及方法
摘要：
一种多缸柴油机供油提前角的调整装置及方法，装置包括装配在柴油机中的齿轮室、连接盘和安置在齿轮室外左端面上的高压油泵，所述高压油泵的主轴端头伸入齿轮室内与连接盘连接；连接盘的右端面上连接有喷油泵正时齿轮，喷油泵正时齿轮的右端面上距离中心沿圆周方向设有三个等分贯穿的圆弧腰形孔，在腰形孔上放置有环形垫鉄；采用紧固螺钉将喷油泵正时齿轮连接在连接盘的右端面上；喷油泵正时齿轮的右端面上设有的圆弧腰形孔中至少在一个腰形孔的逆时针方向的末端且距离腰形孔处还设有一贯穿的圆孔；圆孔安装有一只螺母轴线与喷油泵正时齿轮端面平行的T形螺母；T形螺母内设有一钉头顶支在环形垫鉄上的支撑螺钉。本发明调整方便，调整精度高。
摘要（英）：

A device and method for adjusting a fuel supply advance angle of a multi-cylinder diesel engine includes a gear chamber, a connecting disc and a fuel pump, wherein the gear chamber and the connecting disc are in the diesel engine, and the fuel pump is at a left end surface outside the gear chamber. A main shaft end of the fuel pump extends into the gear chamber. A right end surface of the connecting disc connects to a timing gear. A right end surface of the timing gear has three penetrating circular-arc waist-shaped holes. Annular sizing blocks are arranged on the waist-shaped holes. A penetrating circular hole is at a tail end of the waist-shaped holes. The circular hole is provided with a T-shaped nut. A support screw is arranged in the T-shaped nut, and the screw head of the support screw is jacked against the annular sizing block.
