摘　　要：直接点火有利于改善汽油发动机的排放、提高点火系统的可靠性。本文提出了直接点火系统次级电压与点火能量的设计计算模型，设计了LJ276Q发动机直接点大系统，研制了样品，并进行了排放对比试验，研究的结果可为今后直接点火及电喷点火系统设计提供有效的手段。Direct ignition is beneficial to improving the exhaust emission of gasoline engine and thereliability of ignition system. A design and calculation model for secondary voltage and ignition energy ofdirect ignition system has been proposed, a direct ignitaiton system for LJ276Q engine has been designed, prototype has been made and emission comparison test has been conducted. The research result provideseffective method for the design of direct ignition and electric injection ignition system in the future.
