启动柴油机，怠速空转2～3min，用手触摸各缸排气口及喷油器附近的缸盖，若某缸温度过高，可初步断定该缸供油量偏多。
(3)当机温超过50℃时，加大油门，让发动机在额定转速下运转，同时查看各排气口的烟色，注意倾听气缸的声音。若某缸冒黑烟，说明供油量过大，以工程机械装用较多的135系列柴油机为例，可将喷油泵调节齿杆向停油方向拉出，松开调节齿轮上的锁紧螺钉，取一根细铁棒插入油量控制套筒的小孔内，用榔头轻敲，使其向右转动，便可减小供油量，反之则增加。
当某缸有清脆的敲击声，且启动困难，说明供油开始过早；若某缸温度偏高，甚至有火焰喷出，则可能是供油开始时间过迟。如135系列柴油机，各缸供油开始时间的调整，是以油泵柱塞的位置决定的。当供油开始时间过迟时，应将定时调节螺母与螺钉旋出一些，供油开始时间过早，则将此螺钉拧紧一些。
(4)检查供油提前角
一般可用溢油法来检查供油提前角，即将油泵一头的高压油管接头松开，将连接喷油器一端的接头拆下，把油管转向水平位置，然后拧紧油泵的高压油管接头，油门拉到，打开减压摇车，直到高压油管出口处冒出几滴柴油时为止。擦净油管出口处的柴油，再慢慢转动飞轮。同时注意观察高压油管出口处的油面，在其开始上动的瞬间立即停止转动飞轮。此时，水箱或机体上的刻线应对准在飞轮上止点前16～20°之间。如果两者在对准以前就有油溢出，说明供油提前角太大，供油过早；如果超过了才有油溢出，说明供油提前角偏小，供油过晚。
值得注意的是，对多缸柴油机，需安装玻璃管和指针，测量缸在压缩上止点时与开始供油时风扇皮带轮上两记号之间的弧长，以确定供油提前角是否正确。同时还要检查各个单体泵供油间歇是否相同，如果不同，可调节柱塞与挺杆之间的间隙或油泵与机体之间的垫片厚度，使供油间歇达到一致。
当供油提前角过小或过大时就需要调整，不同机型的供油提前角的调整方法不同。新195和190型柴油机，是通过增减喷油泵与机体之间的铜垫片来调整供油提前角的。增加垫片供油时间变晚，反之则提早。190-1和1105型柴油机，是调整喷油泵随动柱上的调整螺钉来调整供油提前角的，向里（外）拧螺钉则供油时间变晚（早）。4115型柴油机是通过调整花键接盘与喷油泵传动齿轮的相对位置来改变供油提前角的，花键接盘连同喷油泵的花键轴套顺时针转动一个孔，则供油提前角增加3°，使供油提早，反之，逆时针转动一个孔，则供油提前角减小3°，使供油时间变晚。
