description: The purpose of my work is to study the effect of compression ratio on various characteristics of the combustion process in a petrol engine. To achieve the objectives, I have used a combination of theoretical and experimental methods. In the theoretical part of the work, I analyzed literature sources and models describing the combustion process in the engine. The experimental part included testing of the engine with different compression ratios in laboratory conditions. The main results: 1. Combustion efficiency: The results showed that an increase in compression ratio leads to an increase in the thermodynamic efficiency of the engine. 2. Emissions: With increase in compression ratio, a decrease in carbon monoxide (CO) and unburned hydrocarbon (HC) emissions was observed. However, at too high compression ratios, nitrogen oxide (NOx) emissions increase, requiring additional neutralization systems. 3. Engine durability: Higher compression ratios can also increase stresses on engine components, which can have a negative impact on engine life.
