Description The investigation was carried out on the comparative study of performance parameters of combine-harvesters.
The main objectives of the study were to compare the existing engine performance data with the results obtained from the
test report released by testing institutes and to study the extent of labor, fuel and cost involved in testing the engine.
Kirloskar engine (Model 6R-1080) used in three different makes of combine harvesters, was tested three times with
combines at NRFMT&TI (Hisar) during different years. Although this model of engine was already tested at
A.R.A.I.(Pune) as per the BIS codes. The average mean values of engine performance data, tested at NRFMT&TI (Hisar)
were compared with the engine performance obtained at A.R.A.I. (Pune). Ashok Leyland engine (Model ALU-400) used
in 22 different makes of combine harvesters was tested 22 times with combines at NRFMT&TI (Hisar) in different years.
The testing performances of Ashok Leyland engines used in 22 different combines were compared on the basis of mean
values of performance data. Four testing performance parameters of engine viz. power (kW), torque (N-m), fuel
consumption (l/h) and specific fuel consumption (g/kW-h) were selected to compare the engine performance, as given in
the engine test report of the combine harvester. Mean values of all the performance parameters in Kirloskar engines
(Model 6R 1080) obtained under varying speed and varying loads in different testing institutes were similar. The
percentages of variations in all the testing parameters were found to be very low in varying speed and varying load test.
There was no significant effect on performance parameters of the engine tested during different periods and different
testing institutes. So, there was unnecessary expenditure in conducting testing of Kirloskar engines (Model 6R 1080) again
at combine testing institute with no fruitful contribution to the results already obtained at A.R.A.I.(Pune). Performance of
all testing parameters in Ashok Leyland engines (Model ALU-400) obtained under varying speed and varying load tests
were also similar. There was no significant effect on engine performance parameters in varying speed and varying load
tests in engines tested during different periods, at NRFMT&TI (HISAR). Performance of all the testing parameters in
Ashok Leyland engines (Model ALU-400) obtained in maximum power test and five hours rating test were similar. The
percentages of variations in all the performance parameters were found to be very low in maximum power test and five
hours rating test. There was non-significant difference in engine performance parameters under maximum power test and
five hours rating test of engine tested during different periods, at NRFMT&TI (HISAR). Total cost of complete testing of
engine of combine harvester, at NRFMT&TI (Hisar) observed was Rs. 1.38 lacs. Retesting of Kirloskar and Ashok
Leyland engines used on combine harvesters, resulted in extra expenditure of Rs.1.38 lacs on testing and also unavoidable
delays. Therefore this practice needs to be reviewed at the testing institute level to economize the cost of combine testing.
Retesting of engines of combines at testing institutes may be discontinued to save time, labor, energy and money.
