Effect of Intake Conditions and Combustion Factors on Gasoline and Diesel Engines Performance and Exhaust Emissions

Ahmed Sayed A. Hassan, Ali Saeed Al-Shahrany.


Abstract
The study aimed to investigate the effects of intake conditions, including water injection, filter presence, and temperature variations, on the performance of petrol and diesel engines. The experiment was conducted on single-cylinder four-stroke engines at varying speeds and loads. The composition of the exhaust emissions was analyzed to determine the combustion method. The results indicated that injecting a mixture of water and air into the engine inlet could reduce engine emissions by 17-33% and exhaust temperature by 13-35% for both engines. When an air filter and water injection were present, air flow restrictions in the air inlet led to better combustion and less unburned mixture due to increased air availability. The study also investigated the impact of combustion parameters on heat generation and emissions inside the combustion chamber of gasoline and diesel engines. The parameters studied included intake temperature, intake pressure, equivalence ratio, compression ratio, engine speed, turbulence kinetic energy, and combustion chamber design. The test results showed that higher intake temperatures lead to increased heat generation, increased overall engine efficiency, and reduced CO2 and NOx emissions in gasoline engines. Increasing the value of the parity ratio also led to improved overall efficiency of the two engines.

Key words: Gasoline engine; Diesel engine; Four strokes; Combustion; Water injection; Emission
