DEVICE FOR DIAGNOSTICS OF POWER PLANTS AND FOR DETERMINING OPERATIONAL PARAMETERS OF VEHICLES Russian patent published in 2007 - IPC G07C5/08 

FIELD: controlling and measuring equipment, possible use during testing, examination and operation of mobile agricultural devices, vehicles, caterpillar vehicles and other mobile objects, fitted with diesel engines, and also for complex diagnostics of their technical condition during operation.

SUBSTANCE: in accordance to the invention, introduced to the device are: indicator of quantity and quality of admixtures in the oil of oiling system, two indicators of cooling liquid pressure, fifth and sixth primary converters and informational display for showing failures of power plant. Indicator of quantity and quality of admixtures in the oil of oiling system through the fifth primary converter is connected to third input of analog-digital conversion block. Two cooling liquid pressure indicators through the sixth primary converter are connected to fourth input of analog-digital conversion block. Second input of analog-digital conversion block is connected to third output of block for controlling transmitter-receiver, and output is connected to input of comparison element. First output of comparison element is connected to key, and second one - to information display of power plant failures.

EFFECT: increased operational reliability of power plants of vehicles due to expanded range of diagnosed parameters, lowered laboriousness of measurements during registration of operational parameters, expanded functional capabilities of the device.
