Q6. Answer following questions by True or False 1. Injector that sprays into the intake system operate at the same pressure of the carburetor. 2. Swirl in the cylinder enhances the mixing of air and fuel to give a homogeneous mixture in the very short time. 3. Flame development region is consumed 80% of the air-fuel mixture. 4. Maximum temperature and pressure of flame propagation occurs somewhere between 20" and 30° aTDC for a four-stroke cycle. 5. Knock caused by self-ignition could occur in SI engines as well as in CI engines. 6. Detonation is the minimum combustion time possible without actually having an instantaneous constant-volume reaction. 7. Combustion in a CI engine is a flame front moving through a homogeneous mixture. 8. Fuel injection time in CI engine is usually starting at about 15° bTDC and ending about 5° aTDC. 9. Exhaust blowdown occurs when the exhaust valve starts to open somewhere around 60° to 40° bTDC. 10. The average temperature in the exhaust system of a typical CI engine has been lower than SI engine exhaust.
