摘　　要：电控汽油喷射能有效地改善发动机的性能,特别对小型无人机发动机,可以实现空中飞行过程中对发动机各参数的实时控制。本文以试验研究为手段,介绍了电控汽油喷射在小型无人机发动机上应用研究的初步成果,然后从理论上分析了电控汽油喷射改善发动机性能的因素和潜力,并且强调了它在小型无人机发动机上应用的重要性。The electronically controlled gasoline injection can improve the engine performance, especially for the engine of the mini-unmanned air vehicle (Mini-UAV), which can realize the real-time control of all the engine parameters during the process of flying and make the engine performance go up to a new stage and furthermore promote the development of UAV technology. The paper introduces the initial results of the application research on petrol spurt controlled electronically to the UAV's engine are presented, and how the gasoline injection is controlled electronically to improve the engine performance is described.
