Chemistry in Automobiles:
For an internal combustion engine to move a vehicle down the road, it must convert the energy stored in the fuel into mechanical energy to drive the wheels. In your car,the distributor and battery provide this starting energy by creating an electrical "spark",which helps in combustion of fuels like gasoline. Below is the reaction depicting complete combustion of gasoline in full supply of air:
2C8H18(l) + 25O2(g) → 16 'X' + Y
‘A student while walking on the road observed that a cloud of black smoke belched out from the exhaust stack of moving trucks on the road.’ Choose the correct reason for the production of black smoke:

Spark. The spark ignites the fuel-air mixture in the engine's cylinders, causing a controlled explosion that pushes the pistons down and turns the crankshaft. This converts the chemical energy in the fuel into mechanical energy, which is then used to rotate the wheels and propel the vehicle forward.
Chemistry plays a crucial role in the combustion process. The fuel used in automobiles is typically a hydrocarbon-based compound, such as gasoline or diesel. When these fuels are burned, they undergo a chemical reaction known as combustion. During combustion, the hydrocarbon molecules react with oxygen from the air to produce carbon dioxide (CO2), water (H2O), and energy in the form of heat.
The combustion process is carefully controlled to ensure efficient and complete burning of the fuel. This is achieved by maintaining the correct air-fuel ratio, which refers to the ratio of air molecules to fuel molecules in the combustion chamber. In gasoline engines, the ideal air-fuel ratio is around 14.7:1, meaning there are 14.7 parts of air for every one part of fuel.
To achieve this optimal ratio, the carburetor or fuel injection system in an automobile carefully meters the amount of fuel that is delivered to the engine. The fuel is mixed with air in the intake manifold before entering the combustion chamber. This ensures that the fuel is evenly distributed and allows for complete combustion.
Chemistry also plays a role in improving the performance and efficiency of automobile engines. For example, the use of additives in gasoline can help improve fuel economy, reduce emissions, and prevent engine deposits. These additives often contain chemical compounds that act as detergents, dispersants, or anti-knock agents, which help clean the engine and prevent knocking or pinging during combustion.
In addition, catalytic converters in automobiles are designed to reduce harmful exhaust emissions. These devices contain catalysts, usually made of precious metals such as platinum, palladium, and rhodium, which promote the conversion of harmful pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), and unburned hydrocarbons (HC), into less harmful substances like carbon dioxide, nitrogen, and water.
Overall, chemistry plays a vital role in the operation, performance, and environmental impact of automobiles. Through the careful control of combustion processes and the use of additives and catalysts, chemistry helps improve fuel efficiency, reduce emissions, and enhance the overall driving experience.
