A. Discuss how the (Cetane & Octane ) numbers are affected by the following engine parameters: А. 1) Ignition delay 2) Method of injection 3) Engine Design 4) Compression ratio 5) Type of ignition 6) Flame speed В. Discuss Why? 1) The two-stroke cycle engine must always have an intake pressure boost. 2) In compression ignition engines, no fuel is added to the incoming air, so that compression is done on air only. 3) In two- stroke SI engines, scavenging lasts until piston passes BDC and closes intake and exhaust ports. 4) In Dual cycle, combustion occurs once at constant volume and continued at constant pressure.
