Combustion Chamber Design Features to Reduce Knocking in S.I. Engines
Knocking in S.I. engines occurs due to uncontrolled combustion of the air-fuel mixture which results in high pressure and temperature. This can cause damage to the engine and reduce its efficiency. The following combustion chamber design features can reduce knocking in S.I. engines:
1. Wedge shaped combustion chamber: A wedge-shaped combustion chamber has a small surface area, which reduces the flame travel distance and ensures that the flame front moves smoothly and quickly across the combustion chamber. This reduces the chances of knock.
2. Short flame travel distance: A short flame travel distance reduces the time available for uncontrolled combustion to occur. This is achieved by designing the combustion chamber in a way that the distance between the spark plug and the farthest point of the chamber is minimized.
3. T-head: A T-head combustion chamber design has the spark plug located near the inlet valve. This allows the flame front to travel towards the exhaust valve, which reduces the chances of knock.
Therefore, options 3 and 4 are correct as they mention the wedge-shaped combustion chamber and short flame travel distance. Option 1 is incorrect as the location of the spark plug near the inlet valve is a feature of the T-head combustion chamber (option 2) and not the wedge-shaped combustion chamber.
