Question

1. explain how gasoline powers an engine?
2. how much air is needed to burn 1 gallon of gasoline?
3. what are the byproducts created from a gasoline engine?
4. what is the purpose of a fuel filter?
5. what is a fuel injector?

Explanation:

1. Gasoline is ignited in the engine's cylinders. The combustion creates high - pressure gases that push the pistons, converting chemical energy to mechanical energy.
2. Approximately 14.7 pounds of air is needed to burn 1 gallon of gasoline in a stoichiometric mixture. This is based on the air - fuel ratio for complete combustion.
3. Byproducts of a gasoline engine include carbon dioxide, water vapor, carbon monoxide (in incomplete combustion), nitrogen oxides, and unburned hydrocarbons.
4. The purpose of a fuel filter is to remove contaminants such as dirt, rust, and debris from the fuel before it reaches the engine, protecting engine components.
5. A fuel injector is a device that sprays fuel into the engine's intake manifold or cylinders in a precise amount and at the right time for efficient combustion.

Answer:

1. Gasoline is ignited in cylinders, combustion pushes pistons converting chemical to mechanical energy.
2. About 14.7 pounds of air for stoichiometric combustion.
3. Carbon dioxide, water vapor, carbon monoxide, nitrogen oxides, unburned hydrocarbons.
4. Removes contaminants from fuel to protect engine.
5. Device that sprays fuel precisely for combustion.
