Estimación del consumo de combustible y medición de CO2 en un vehículo con sistema de inyección CRDi 2.0 litros en arranque en frio

Abstract

The study analyses fuel consumption and CO₂ emissions in CRDi fuel-injected diesel engines. The theoretical foundations, evolution in South America and environmental benefits are reviewed. Fuel consumption and emissions are measured in a 2.0 L CRDi engine during cold start using scanners and gas analysers under various driving conditions. Statistical models are applied to identify factors influencing engine efficiency. The results allow optimisation of thermal management and fuel injection, contributing to strategies to reduce the environmental impact of modern diesel engines.
