Check all the engines system like cooling
system, fuel system and attachment of rope
brake dynamometer.
• The fuel which is weighted at outside is
filled up in the fuel tank.
• Insert the ignition key and start the engine
by cranking.
• First, the engine should be run on No-load
Condition. And note down the time of start
of engine.
• The idling (No load mode), is adjusted by
the adjustable screw provided at the throttle
body in such a way that the speed of the
engine during idling is maintained about
1500 rpm.
• Then, allow the engine to run on this
condition up to one hour and after one hour
shut off the engine.
• Then, the door of the fuel tank is opened and
remaining fuel in the fuel tank is drawn
outside and weighed again.
• Note down the fuel consumption of engine
on idling condition during one hour running.
• Then, 10 Kg. weight is applied on the rope
brake dynamometer, by adjusting the dead
weight on the rope so that, the net load on
the engine (W –S) = 10 Kg, where W =
Dead Weight (L * 9.81) N. and S = spring
Pull (N).in running condition of engine at
1500 rpm constant.
• Then, again the fuel tank is filled with the
weighted fuel and allows the engine to run
on same condition for one hour.
• After one hour, shut-off the engine and
drawn out the remaining fuel from the fuel
tank by opening bottom door and
weightened it.
• Note down the fuel consumption of engine
on 10 Kg. load condition during one hour
running.
• Repeat the same procedure for applying the
load 20, 30 and 40 Kg. successively and
note down the fuel consumption for 1 hour
running of engine.
