The range of mechanical efficiency for automobile engines is
The measurement of frictional power by Willians line is applicable to
The most accurate method of determining fp is by
In the air box method of measuring air flow, the air box is provided to
The best method of measuring speed is by
Mechanical or electrical tachometer can also be used for measuring are not very accurate. For accurate and continuous measurements of speed of magnetic pick-up placed area a toothed wheel coupled to the engine shaft is used. The magnetic pick-up will produce a pulse for every revolution and a pulse counter will accurately measure the speed.
Volumetric efficiency is a measure of
Indicated power is directly proportional to
IP = Ma x network
Sankey diagram represents
Which among the following type of engine indicators are most commonly used?
A single cylinder engine running at 2200 rpm develops a torque of 8 Nm. The indicated power of the engine is 2 kW. What is the loss due to friction power as the percentage of brake power?
