Stages Of Combustion In Ci Engine. In the above Pressure vs cranks Angle diagram of the four-stroke spark ignition engine a b is the Compression process and b c is the combustion process c d is the expansion process. The small droplets of liquid fuel evaporate to vapor. Ie at top dead centre. - Air cell chamber - M Combustion.
Ignition Delay period Pre-flame combustion Uncontrolled combustion Controlled combustion After burning 21. This after burning may be there due to fuel particles residing in remote position in combustion space where flame front could not reach. This period is counted from the start of injection to the point where the pressure- time curve separates from the motoring curve indicated as start of combustion. The combustion in a CI engine is considered to be taking place in four stages. Stages of Combustion in CI engines four stages The Ignition Delay Period is also called the preparatory phase during which some fuel has already been admitted but has not yet ignited. As you can see that the pressure rise during the combustion process is at constant volume in the theoretical cycle.
The small droplets of liquid fuel evaporate to vapor.
Induction swirl turbulent combustion chambers. - Air cell chamber - M Combustion. High air temperature needed for this vaporization process requires a minimum compression ratio in CI engines of about 121. Ie at top dead centre. 12 a i Explain with a P-θ diagram the various stages of combustion in a CI engine 8 iidiscuss the characterstics of DIand IDI diesel engine 8 12b i What do you understand by turbo charging. As you can see that the pressure rise during the combustion process is at constant volume in the theoretical cycle.
