用于监测发动机润滑系统机油油压状况的保护系统
摘要：
本实用新型涉及一种用于监测发动机润滑系统机油油压状况的保护系统，包括压力传感器、机油保护器和至少两个点火器，机油保护器包括处理器、压力信号检测电路、转速信号检测电路、熄火控制电路、延时电路、电源电路，电源电路将点火线圈产生的电压转换为机油保护器的供电电压为机油保护器供电，压力信号检测电路监测润滑油道的机油压力信号，所述转速信号检测电路监测发动机转速信号，处理器将发动机转速信号与转速设定值进行比较，将机油压力信号与压力设定值进行比较，输出控制信号给熄火控制电路，熄火控制电路控制发动机熄火停机。其能够保证发动机不会因为缺少机油或者润滑油压过小、润滑不良而造成发动机曲轴等运动部件抱死损坏发动机。
摘要（英）：

The utility model relates to a protection system for $monitoring engine lubrication system machine oil oil pressure situation, including pressure sensor, oil protector and two at least point firearms, oil protector includes treater, pressure signal detection circuitry, rotational speed signal detection circuitry, flameout control circuit, delay circuit, power supply circuit, and oil protector 3 that oil protector 1 that power supply circuit produced oil protector 0 be oil protector is the oil protector power supply, and pressure signal detection circuitry monitors the machine oil pressure signal of lubrication oil duct, rotational speed signal detection circuit monitors engine speed signal, and the treater carries out the comparison with engine speed signal with the rotational speed setting value, carries out the comparison with oil pressure signal with the pressure setting value, and output control signal gives flameout control circuit, and flameout control circuit control engine is flame -out to shut down. It can guarantee that the engine can not be because of lacking machine oil or lubricating oil pressure undersize, lubricated bad and cause moving part locking such as engine crankshaft to damage the engine.
