Which of the following feature(s) is/are used in the combustion chambe...
Reducing knock in a spark-ignition (S.I) engine is crucial to ensure efficient and reliable operation. Knock refers to the undesirable combustion phenomenon that occurs when the air-fuel mixture in the combustion chamber detonates spontaneously instead of being ignited by the spark plug. Knock can lead to engine damage and reduced performance. To reduce knock in the combustion chamber design of an S.I engine, the following features are used:
Wedge-shaped combustion chamber: One of the key features used to reduce knock is the design of a wedge-shaped combustion chamber. The wedge-shaped combustion chamber has a narrow end, where the spark plug is located, and a wider end, where the fuel-air mixture is ignited. This design promotes a more controlled and efficient combustion process by allowing the flame to propagate from the spark plug towards the wider end of the combustion chamber. The wedge shape helps in achieving better flame propagation and reduces the chances of knock.
Short flame travel distance: Another important feature used to reduce knock is the use of a short flame travel distance. The flame travel distance refers to the distance that the flame front needs to travel from the spark plug to reach the farthest end of the combustion chamber. By reducing this distance, the time it takes for the flame to reach the farthest end is minimized. A shorter flame travel distance ensures that the combustion process is completed before the pressure and temperature rise to levels that can cause knock.
Explanation of the correct option:
Among the given options, option 'C' includes both the wedge-shaped combustion chamber and short flame travel distance. This combination of features is effective in reducing knock in an S.I engine. The wedge-shaped combustion chamber promotes better flame propagation, while the short flame travel distance ensures that the combustion process is completed quickly, minimizing the chances of knock. Therefore, option 'C' is the correct answer.
In conclusion, reducing knock in the combustion chamber design of an S.I engine is achieved through the use of a wedge-shaped combustion chamber and a short flame travel distance. These features promote better flame propagation and ensure that the combustion process is completed efficiently, minimizing the chances of knock.
