A failure judgment device for a thermostat 16 arranged in a circulation passage 13 of cooling water 12 in an engine 1 includes a water-temperature sensor 18 for detection of a temperature of cooling water 12 having passed through the engine 1, and a contro...

The present invention relates to a method and system for detecting a presence of a block heater in an automobile. In one embodiment, an automobile includes an engine, a radiator, an engine coolant temperature ("ECT") sensor, and/or an engine control unit (...

There are occasions when an intermittent abnormality occurs in a water temperature sensor (16) that is of a type that does not cause a sudden change in a detection value of the water temperature sensor (16). The movement of the detection value of the water...

The device has a sensor (7a,7b) for measuring a component temperature mounted on the internal combustion engine, further sensors for direct or indirect detection of engine revolution rate, fuel injection quantity, charging air temperature and cooling water...

The device has a bearer structure (4), two sensor elements (2,3) accommodated on the structure, a device for feeding at least a sub-flow (V1') of an engine induction flow (V1) to the first sensor element and a device for feeding at least a sub-flow (V2') o...

A on-board-diagnostic (OBD) system is disclosed for a vehicle having an intercooled supercharged engine 12. An engine management system (EMS) 38 monitors the difference in air temperature 28, 34 across an intercooler 20 and increments a counter 40 if there...
