Control method for oil injection of engine

The invention relates to a control method for oil injection of an engine. The control method comprises the steps that first operation data of the engine are obtained; determining whether the engine is in a first state or a second state based on the first operating data; and when the engine is in the first state, the engine is controlled to conduct oil injection in the cylinder for one time, when the engine is in the second state, the engine is controlled to conduct oil injection in the cylinder for two times, and the interval between the two times of oil injection is preset duration. Corresponding oil injection control methods are adopted according to different operation data of the engine, so that fuel of the engine is fully mixed with air, the combustion efficiency is improved, and oil consumption is reduced. 本发明涉及一种发动机的喷油的控制方法，该控制方法包括：获取发动机的第一运行数据；基于第一运行数据确定发动机处于第一状态或第二状态；在发动机处于第一状态下，控制发动机在缸内进行一次喷油，在发动机处于第二状态下，控制发动机在缸内进行两次喷油，且两次喷油之间间隔预设时长。针对发动机的不同运行数据采用相应的喷油控制方法，使发动机燃料与空气充分混合，提高燃烧效率，降低油耗。
