Implementation of 80MHz NodeMCU Lolin for Realtime Precision Maintenance Scheduler CPS Calculation on a Volvo In-Line D16C610 Engine

Abstract

The frequent use of the Volvo engine for mechanical hauling necessitates a real-time and intelligent approach to when and how to perform periodic maintenance. The single or double trailer (vessel) that the Volvo FH16 prime mover truck is equipped to pull may weigh between 280 metric tons. Unfortunately, the Service-Meter (SM), which counts engine operating hours without accounting for engine speed, load, or oil temperature, serves as the primary basis for the maintenance schedule. As a result of this faulty parameter, the maintenance schedule became inefficient and flawed. A NodeMCU Module is installed on an ECU to include crankshaft rotation to Hour Meter parameter which used to decide when to carried out the periodic maintenance. The wear components inside the engine that is in contact with rotating or moving parts such as crankshaft, camshaft, piston cylinders specifically the rings, cylinder liner, and connecting rod are all depend on the number of crankshaft rotation. By including the crankshaft RPM when the engine is operating, using SMconv, The most frequent maintenance service (PS250) is carried out approximately every 11 days (previously every 15 days). By making PS250 more frequent which means replacement of engine oil, engine oil filter, and secondary fuel filter (racor filter) will be done more frequently. The result and effect of the maintenance is therefore in accordance with metal wear pace inside the engine. Therefore, by modifying the SM parameter the more frequent maintenance service is expected to make make better MTBF and MTTR thus resulting in longer engine lifetime.
