Why We Do Not Use Same Technology To Start Both Si/cl Engine ? |
|
Answer» The S.I. or spark ignition engine uses PETROL. as a FUEL and the Ci. or compression ignition engine uses diesel as a fuel. Both the fuels has different compression ratio.
So in case of SI engine, the compression ratio is not sufficient for fuel to burn so a spark PLUG is USED, whereas in ci engine, the compression ratio is so high that due to its internal heat the fuel is combusted so there is no need for a spark plug. So the technology used in SI engine is different from CI engine. The S.I. or spark ignition engine uses petrol. as a fuel and the Ci. or compression ignition engine uses diesel as a fuel.
