Abstract

Design Engineer often require vital information related to field operating condition, which can be used to improve and optimize their designs. To meet this need a data logging/analyzer system has to be developed. Existing systems available in the market which are capable of logging field data are complex, costly and are not able to determine the overall performance of vehicle due to its limited functionality.

The purpose of this paper is to develop a Data logging and Analyzer System using CANlog4 device that will help us to determine the Engine performance of “John Deere 5000 series Tractor”. The CANlog is a programmable device used to log data on CAN bus. Software is developed in LTL programming language for CANlog device such that it will monitor the Tractor CAN bus and will log the engine performance parameters on the bus. An offline analysis is performed on the logged data using ICE-GlyphWorks tool which will help us to Graphing of logged data for performance comparison.

In this paper the behavior of various engine performance parameters like break torque, break power, indicated power, friction power, mechanical efficiency, mean effective pressure and specific fuel consumption are studied over its speed range which will helps us to do the performance comparison. Also the time distribution of parameters like engine speed, engine torque, engine break power, engine percent load, fan speed, ambient air and coolant temperature are graphically summarized using Histogram which will helps us to know the concentration areas of the particular parameter over its test period of time. It has been observed from the result that the maximum torque and maximum power developed by the engine is 307 Nm and 64.57 kW at the speed of 1332 rpm and 2450 rpm respectively. The maximum power loss observed is 36kW and the average pressured generated inside the cylinder is 400kN/m2. The maximum mechanical efficiency of the engine is observed at the speed of 1900 rpm. The engine speed is more concentrated between the ranges 2000 to 2250 rpm during its test period of time.
