Heat engines operation preventing device, has thermal and oil pressure switches with time lag relays for preventing operation of heat engine when temperature of cylinder head is high, and relays for signaling temperature fault

摘要

The device has electrical circuits connected on a thermal switch (1) and an oil pressure switch (3). The switches have time lag relays (Rt1, Rt2) for preventing the operation of a heat engine when the temperature of a cylinder head of the heat engine is high, and relays (T1, T2) for signaling the temperature fault. A thermostat (5) is fixed on the cylinder head using a clamp.
