Rising demand for petroleum products in road transport, together with harmful exhaust emissions from internal combustion engines, is intensifying the need to improve vehicle energy efficiency and to introduce alternative fuels. This study evaluates the operational, energetic, and environmental performance of two passenger cars widely used in Uzbekistan — the Chevrolet Cobalt and the Chevrolet Tracker — when operated on a synthetic gas (syngas) blend, using a MATLAB/Simulink simulation framework. The adopted syngas composition consists of 55% CH₄, 20% H₂, 20% CO, and 5% CO₂. The simulation model jointly evaluates engine torque, power, fuel consumption, thermal efficiency, vehicle acceleration, and CO, CO₂, and NOx emissions under an urban driving regime. Relative to gasoline operation, the model shows a modest reduction in maximum torque (about 3%) and power (about 5%), accompanied by a substantial 17–19% reduction in fuel consumption, a 14% increase in thermal efficiency, and marked emission reductions of 62% (CO), 28% (CO2), and 48% (NOx). These results indicate that syngas is a technically viable and environmentally favorable alternative fuel for the passenger-car fleet operating under Uzbekistan's real-world driving conditions, and they establish a basis for vehicle-specific validation on the Chevrolet Cobalt and Chevrolet Tracker platforms.
