A 4-cylinder gasoline engine has an efficiency of 0.230 and delivers 205 J of work per cycle per cylinder. When the engine fires at 23.3 cycles per second, what is the work done per second?
As the engine consist of 4 cylinders, the work per cycle is given by,
W = 205 * 4 = 820 Joules/cycle
Number of cycles per second = 23.3 cycles in one second, given
This solution calculates the work done per second by 4-cylinder gasoline engine.
