The total friction mean effective pressure of a 4-cylinder Sl engine has a quadratic function with a = 92, b = 2.3 and c= 3.5. Three measurements have been done at three different engine rotational speeds N. The amep is found equal to 12.3, 21.4 and 28.7 kPa and the pmep is found equal to 11.03, 3.225 and 51.83 kPa at Nequal to 1500, 2500 and 5500 rpm respectively. If the mechanical efficiency is equal to 0.84, the indicated mean effective pressure at N = 6600 rpm is equal to (in kPa):
