The reason behind Vapor lock in IC engines is ___________.

Explanation:

Vapor Lock in IC Engines

• Vapor lock is a condition that occurs in internal combustion (IC) engines where the fuel supply to the engine is interrupted or partially blocked due to the formation of vapor or fuel bubbles in the fuel delivery system. This can lead to engine stalling, difficulty in starting, and poor engine performance.
• Vapor lock happens when the fuel in the delivery system, typically in the fuel lines or carburetor, vaporizes due to high temperatures. When the fuel turns into vapor, it creates bubbles that can block the flow of liquid fuel to the engine. This interruption can cause the engine to run lean, misfire, or stop running entirely.

Causes of Vapor Lock:

• High ambient temperatures, which can cause the fuel to vaporize more easily.
• High engine compartment temperatures, often due to prolonged idling or slow traffic conditions.
• Low fuel pressure, which can reduce the boiling point of the fuel and make it more prone to vaporization.
• Use of fuels with high volatility, which are more likely to vaporize at lower temperatures.
