Intelligent Engine Running Hour Meter
Abstract: The mechanism of the present invention comprises of a microcontroller and a service indicator for the engine and its accessories. The vehicle speed and distance covered input is provided to the controller through the instrument cluster. The engine speed signal is taken through the alternator. The process incorporated in the controller is in such a way that it logs the engine running time based on the engine speed, vehicle speed and distance travelled. The weightage is given for three different types of load for the engine viz total engine running time in locomotion, total engine running time at idle rpm and total engine running time in loaded condition. The time is logged at the idle rpm if the engine continues at idle for more than 2 minutes. The time is logged for loaded condition if the vehicle speed is less than 5 kmph and the engine rpm is more than 1.2 times the idle rpm, this is to take into account the powertrain take off applications where in the engine is loaded but the vehicle is not running. An indication for service is provided through the means of a display in the cluster. In addition to that, there will be separate indication for the replacement of fuel filter, air filter etc. Once the service/replacement is done, the driver/mechanic has to reset the time counter for the next servicing cycle. This can also be used as a tool for warranty claim settlement, if the service is skipped. Figure - 2
