Question 3Motor Plants - Assistant Engineer

The correct answer is A) 17.6 kg/cm2. To calculate the cylinder mean effective pressure (CMEP), we can use the formula: CMEP = (Indicator diagram area) / (Indicator diagram length) x (Scale of the indicator spring). Given information: - Indicator diagram area = 22 cm2 - Indicator diagram length = 12.5 cm - Scale of the indicator spring = 1 mm = 1 kg/cm2 Plugging in the values: CMEP = (22 cm2) / (12.5 cm) x (1 kg/cm2) CMEP = 1.76 kg/cm2 Therefore, the cylinder mean effective pressure is 17.6 kg/cm2, which is the correct answer. The other options are incorrect because they do not match the calculated value of 17.6 kg/cm2.
