Hi,
Thanks for the reply. I am using a kind of an electro-magnetic brake to apply the load.
The readings at the low revs and high load are actually the last readings that i took before i started unloading the engine. I start with no load on the engine and then start applying the load. However if i go beyond the highest loading pt.(lowest rpm point), the engine starts to stall, the rpms decrease real fast and the engine stops. So either i am unable to see the peak or the lowest rpm point is my peak and i can't take a reading below that.
The point is my highest loading point seems to be my peak and any rpm greater than that gives me lesser torque and power. But going by other power curves, this shouldnt be happening. There should be lower rpms where i can get some torque without the engine stopping on me.
All the data points were taken with the engine on full throttle and the mixture setting on the optimum point for the engine.
Another thing i want to ask is whether the engine is tested at full throttle to get the curves or is the throttle position adjusted at each load setting to get the maximum torque at each engine rpm.?
Thanks,
Shyam.
