汽油发动机点火系统点火率计(或称断火测试仪)是汽车电器在试验台上进行三针放电试验时,定量测定点火系断火的仪器。以往测点火系断火是用目测耳听的方法,而点火率计实现了用数字直读式判断断火与否。该仪器能定量测定每1000次(或100次)点火中实际点火、断火次数和点火百分率,并用 Gasoline engine ignition system Ignition rate meter (also known as broken fire tester) is a test fixture on the test bed for three-pin discharge test, the quantitative determination of the ignition system off the fire. In the past, the ignition system was measured by the method of measuring the ears, and the ignition rate meter was used to determine whether the digital direct-readout fire or not. The instrument can quantitatively measure the actual ignition, the number of fire and the percentage of ignition every 1000 (or 100) ignition, and use
