A 2 litre four stroke direct injection diesel engine is designed to run at 4500 rpm with a power output of 45 kW . The volumetric efficiency is found to be 80 percent. The brake specific fuel consumption is $0.071 \mathrm{~kg} / \mathrm{MJ}$ and the fuel has a calorific value of $42 \mathrm{MJ} / \mathrm{kg}$. The ambient conditions for the test were 200 C and 1 bar. Calculate (a) BMEP

Explanation

The problem requires us to calculate the brake mean effective pressure of a 2-litre four-stroke direct injection diesel engine.
