What is Brake Power of Diesel Engine?

The actual work of turbocharges is to increase the inlet pressure. Therefore increasing pressure would be a cause an increase in temperature would be an effect. Here, it is asked about cause not the effect. Hence the answer C is valid.

Please give the Brake power formula with detail explanation.

Thank you.

I think this depends on turbo charger principle.

When the pressure of inlet air is high, more amount of air can be accommodated in the cylinder which will result an increase in the O2 content and will provide a better combustion. This will increase the output power.

By supercharger intake the air pressure increases.

What is the meaning of constant parameters here?

Deepak patil said:   1 decade ago
Break power depends on pressure & temperature. So increase in press increases temp & indirectly B.P. also.

Kunal said:   1 decade ago
B.P = pmlan/60, where pm = break mean effective pressure.

Turbocharger is a turbine driven device that increases an engine's efficiency and power by forcing extra air into the combustion chamber, the turbine can force more air and proportionately more fuel into the combustion chamber that atmospheric pressure alone.
