A detection system (59) for determining spark voltage of a spark plug (54) in a capacitive discharge ignition system (52) is disclosed. The detection system may have a sensor circuit (60) configured to detect occurrence of a spark by measuring a voltage on a low side (78) of a primary coil (68). The detection system may also have an electronic control unit (58) connected to the sensor circuit. The electronic control unit may be configured to receive a signal from the sensor circuit indicating that the voltage exceeded a threshold. The electronic control unit may be further configured to determine a spark time based on the signal, and determine a spark voltage based on the spark time. 公开了种用于确定电容性放电点火系统(52)中的火花塞(54)的火花电压的检测系统(59)。该检测系统可以具有传感器电路(60)，其配置成通过测量初级线圈(68)的低侧(78)上的电压来检测火花的发生。该检测系统还可以具有连接到传感器电路的电子控制单元(58)。该电子控制单元可以配置成从传感器电路接收指示电压超过阈值的信号。该电子控制单元还可以配置成基于信号来确定火花时间，并且基于火花时间来确定火花电压。
