The search for alternative fuel for transport vehicles and also replacement of internal combustion engines in order to reduce the harmful emissions have been forcing the vehicle manufacturers to innovate new technology solutions for meeting the stringent legislative targets. Mexico’s commitment for de-carbonisation of transport sector and meeting the environmental goals is shaping it especially, and with this, it favours the move towards electrification of the vehicles. The aim of the present work is to numerically evaluate the possibility of replacing the IC engine in the existing hybrid vehicles with the Hydrogen fuel cell system. This work modelled a Hydrogen fuel cell vehicle based on Toyota MIRAI and validated the fuel economy performance of the vehicle using experimental data. This validated model was used to estimate the fuel economy for real-world drive cycles generated in 2019 from Mexico City.

The present work attempted to investigate the performance and emission characteristics of a diesel engine using conventional diesel fuel with mixtures of animal and vegetable derived bio-diesel that are available in Mexico and ultra low sulphur diesel with varying proportions. This work aimed at studying the performance of the engine at representative ambient conditions of Mexico City which is at an altitude of 2240m above sea level. The work identified that the levels of CO in the exhaust has a strong correlation with the proportion of bio-diesel in the conventional diesel fuel used. However, the performance of the engine, torque and power, are not affected significantly by varying the proportion of animal and bio-derived fuels in diesel fuel. In addition it also identified the correlation between the proportions of bio-diesel in diesel with the engine out particulate matter and the performance of diesel oxidation catalyst.
