In-Vehicle History Recording of Diesel Engine Performance Parameters 810982

Recently developed portable instrumentation has now made feasible and practical the accurate history recording of diesel engine fuel consumption for load factor data along with engine speed and other performance parameters during actual vehicle operation. Engine load factor data is determined by the instantaneous fuel consumption as a percentage of full load fuel consumption and is important in the design and the application of engine components and accessories. The required instrumentation consists of a precision fuel metering system, an electronic tachometer, temperature transducers, and compact integrated circuit histogram data recorders.
