摘　　要：高压共轨柴油机是满足未来汽车排放法规的核心技术,曲轴信号和凸轮轴信号是高压共轨柴油机电子控制单元实时工作的关键,因此研究2个信号的同步具有重要意义。研究了柴油机的曲轴信号和凸轮信号之间的关系,并用32位单片机TC1796的通用定时器阵列(GPTA)模块中的局部定时单元(LTC)产生同步信号,保证了2路脉冲的同步误差为几个指令周期,降低了高压共轨柴油机电子控制单元的研发成本。High-pressure common rail diesel engine is essential to meet vehicle emission regulations in future.The crankshaft signal and the camshaft signal are the keys to ensure that the electronic control units of the high-pressure common-rail diesel engine work in real-time.The relationship between the crankshaft signal and the camshaft signal is studied,and sync signals are generated by using the Local Timer Cell(LTC) of the General Purpose Timer Array(GPTA) module in 32-bit single-chip microcontroller TC1796 to ensure two-way synchronization error of a few instruction cycles only and the cost reduction for development.
