Document Summary
Ice=a device that converts one form of energy into mechanical energy so as to produce motion by burning of the working fluid internally. generates power by combustion of fuel in cylinder. Turbo/super=flip intake and exhaust and higher starting p. Si combustion stages: stage 1: ignition and flame development (5% mixture burned) Electrode gap: too small, quenching of the flame nucleus too large, spark intensity reduced. Mep=avg p when exerted over the stroke wud produce the same work as the varying pressure. Indicated=refers to a calculated value that is generated from a parameter that is found directly through a device or indicator. Imep=mep calculated from in cylinder pressure, avg cylinder pressure over engine cycle. Combustion eff=amount of fuels chemical energy that is released inside the engine during combustion. Thermal eff=relates actual work per cycle to the amount of fuel chemical energy released in the combustion process.
