8/18/2019 TD002 Methanol Brake Power

1/2

Objective:

To determine the brake power of IC engine using Methanol in alternate fuel engine.

Apparatus:

Mega Tech dynamometer/Generator with alternate fuel engine (Model DG-I)

 Technical Data: 

Bore size=!mm

"tro#e=$!mm

%om&ression ratio='

"we&t *olume=+,mm

 Theory:

Brake Power:

 e may define Bra#e .ower as follows

“The power generated by the engine and is measured at output shaft is known as brake

 power” 

Mathematically it can 0e e1&ressed as

BrakePower=2πNT

Facts about Methanol:

Methanol was first manufactured 0y the destructi*e distillation of wood and therefore#nown as wood alcohol4 It is used as a less e1&ensi*e fuel and is ma5orly used in racing

cars4 6ther than that it has an u&&er hand o*er gasoline in the sense that it 0urns o*erlower tem&erature than gasoline which increase it7s utility4
