We used Pb(C2H5)4in the gasoline to reduce:
- A
Consumption of fuel
- B
Price of fuel
- C
The octane number of fueL
- D
Knocking of engine
The addition of Pb(C2H5)4 in gasoline reduces knocking in the engine by increasing the octane number of fuel. Knocking is caused by premature combustion of fuel, which can damage the engine.
The addition of Pb(C2H5)4 in gasoline does not directly affect the consumption of fuel.
The addition of Pb(C2H5)4 in gasoline does not directly affect the price of fuel.
This option is also incorrect. The addition of Pb(C2H5)4 in gasoline increases the octane number of fuel, which measures the fuel's ability to resist knocking in the engine.
The addition of Pb(C2H5)4 in gasoline reduces knocking in the engine by increasing the octane number of fuel. Knocking is caused by premature combustion of fuel, which can damage the engine.
