advance angle

基本解释

After a self adaptive ignition unit is applied, the ignition advance angle of the engine is automatically changed according to different fuels.
采用自适应燃料点火器可根据发动机使用燃料的不同自动改变点火提前角。
The test on the(influence) of changing fuel supply advance angle on fuel economy was carried out on single cylinder diesel engine separately using diesel fuel and ethanol-diesel blend fuel.
在单缸柴油机上分别使用纯柴油和乙醇柴油混合燃料，进行了改变供油提前角对发动机燃料经济性影响的试验。
The test result shows that the influence is more sensible when the ethanol-diesel blend fuel is used, and it is beneficial for increasing the fuel economy to reduce suitably fuel supply advance angle.
结果表明：使用乙醇柴油混合燃料时，供油提前角的改变对燃料经济性的影响比较敏感，且相对使用纯柴油，适当减小供油提前角对提高燃料经济性有利。

What the MotionPlus adds is better sense of the exact hitting angle, which makes for better ball placement in advance modes, but provides quite a considerable learning curve.
