02: A 4-stroke, 4-cylinder, 2.5 liter, SI engine operates on 3000 RPM. The engine has a compression ratio of
8.6:1, a mechanical efficiency of 86%, and an indicated power of 103 kW. Calculate: (i) Cylinder clearance
volume. (ii) Brake mean effective pressure. (iii) Output per displacement.
Q3: A race car burns nitromathane (CH;NO2) with air at an equivalence ratio of 1.1 assuming all nitrogen in fuel
ends up as N2. Determine the AF ratio and the percentage analysis of the combustion products.
04: The following data concerns a 4-stroke engine: I.V. opening period = E.V. opening period, I.V.C. = 56°
ABDC, E.V.O. = 47° BBDC, and the overlap angle = 33°. Calculate: all the missing angles, and the
opening period. Then, draw the valve timing diagram.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa15f0e0c-e022-44ae-be86-a85e15a3386f%2F7b907550-e544-47a8-b49a-844ec744ade2%2F78l9uho_processed.jpeg&w=3840&q=75)
