In IC engine 1. the ideal air capacity of a two-stroke engine is the mass of air required to concurrently fill the total cylinder volume at inlet temperature and exhaust pressure 2. with increase in air-fuel ratio beyond the value for maximum power, there is a fall in power developed and this fall is more with higher values of air-fuel ratio. 3. the volumetric efficiency of the engine depends on the design of intake and exhaust manifold. Which of the above are correct?
