For the same heat input and compression ratio, the most efficient cycle is
An air-standard Diesel cycle consists of the following processes:1-2: Air is compressed isentropically.2-3: Heat is added at constant pressure.3-4: Air expands isentropically to the original volume.4-1: Heat is rejected at constant volume.If γ and T denotes the specific heat ratio and temperature, respectively the efficiency of the cycle is
In an Ideal Otto cycle the air standard efficiency is 56.5%. if the heat added during the constant volume process is 1000 kJ/kg, determine the work done.
In an Otto cycle, the compression ratio is 9 : 1 and the pressure and temperature at the beginning of the compression process are 100 kPa and 10°C. The heat addition by combustion gives the highest temperature as 2500 K.Thermal efficiency of the cycle is:
An Otto cycle has a compression ratio of 8. If 250 kJ of work is extracted from the cycle, the heat rejected by the cycle is
Consider the following statements:1. Both Otto and Diesel cycles are special cases of dual combustion cycle2. Combustion process in IC engines is neither fully constant volume nor fully constant pressure process3. Combustion process in ideal cycle is replaced by heat addition from internal source in closed cycle4. Exhaust process is replaced by heat rejection in ideal cycleWhich of the above statements are correct?
In an Otto cycle, the compression ratio is 9 : 1, and the pressure and temperature at the beginning of the compression process are 100 kPa and 10° C respectively. The heat addition by combustion gives the highest temperature as 2500 K. The highest cycle pressure is:
An otto cycle has a compression ratio of 9. If 1000 kJ of work is extracted from the cycle, the heat rejected by the cycle is (take γ = 1.5)
In air standard cycle analysis of IC engines, which of the following statements is correct?
