Why does petrol operate using SI (Spark Ignition) instead of CI (Compression Ignition)?
Why does petrol operate using SI (Spark Ignition) instead of CI (Compression Ignition)?
- Petrol has a higher flash point and is less volatile, making it suitable for SI engines where it forms a more homogenous mixture with air.
- Petrol has a lower flash point and is more volatile, making it suitable for SI engines where it forms a more homogenous mixture with air. (correct)
- Petrol has a lower flash point and is less volatile, making it suitable for SI engines where it forms a more homogenous mixture with air.
- Petrol has a higher flash point and is more volatile, making it suitable for SI engines where it forms a more homogenous mixture with air.
Why is Diesel fuel not suitable for SI (Spark Ignition) engines?
Why is Diesel fuel not suitable for SI (Spark Ignition) engines?
- Diesel fuel has a lower flash point and is less volatile, making it unsuitable for forming a homogenous mixture with air in SI engines.
- Diesel fuel has a lower flash point and is more volatile, making it unsuitable for forming a homogenous mixture with air in SI engines.
- Diesel fuel has a higher flash point and is more volatile, making it unsuitable for forming a homogenous mixture with air in SI engines.
- Diesel fuel has a higher flash point and is less volatile, making it unsuitable for forming a homogenous mixture with air in SI engines. (correct)
Why is Diesel fuel suitable for CI (Compression Ignition) engines?
Why is Diesel fuel suitable for CI (Compression Ignition) engines?
- Diesel fuel has a higher flash point and is less volatile, allowing it to ignite under compression in CI engines.
- Diesel fuel has a lower flash point and is less volatile, allowing it to ignite under compression in CI engines.
- Diesel fuel has a higher flash point and is more volatile, allowing it to ignite under compression in CI engines.
- Diesel fuel has a lower flash point and is more volatile, allowing it to ignite under compression in CI engines. (correct)
