Question

Hydrogen combustion with air at stoichiometric condition results in:

• A. Reduced HC, CO and NOx emissions
• B. Reduced HC and CO with increased NOx emissions
• C. Reduced HC with increased CO and NOx emissions
• D. Reduced CO with increased HC and NOx emissions

Hint:

Optimizing combustion conditions and exhaust treatment technologies is key to managing NOx emissions in hydrogen-powered engines.

Answer 1

The Correct Option is B

Hydrogen combustion at stoichiometric conditions significantly reduces hydrocarbons (HC) and carbon monoxide (CO) but can lead to higher NOx emissions due to higher combustion temperatures.
