喷油泵的供油量调整包括额定转速(高速)供油量、怠速供油量、启动供油量、校正供油量以及停机供油量等项目。各种供油量是由柴油机制造厂经过反复试验确定的,可根据规定数据来调整。额定转速供油量保证柴油机在额定负荷时所需油量；怠速供油量为维持柴油机空运转时为克服内部阻力所需的油量；启动供油量用以保证发动机的启动,比额定负荷供油量约高50%；校正供油量用于短时超负荷；
Fuel pump fuel supply volume adjustment, including the rated speed (high speed) fuel supply, idle fuel supply, start fuel supply, fuel supply correction and shutdown fuel supply and other projects. A variety of fuel supply by the diesel engine manufacturer after repeated testing to determine, according to the provisions of the data to adjust. Rated speed fuel supply to ensure that the diesel engine at rated load oil required; idling fuel supply to maintain diesel engine idle time to overcome the internal resistance required oil; start fuel supply to ensure that the engine starts than the rated load About 50% higher fuel supply; correct fuel supply for short-term overload;
