“…A number of methods of realizing early three-way catalyst (TWC) light-off have been considered in previous studies [2], but the main approaches are increasing the temperature of the exhaust gas or reducing the weight of the catalyst or of the substrate. However, increasing the temperature of the exhaust gas generally has a negative effect on the thermal efficiency of the engine, reducing fuel efficiency.…”

Brazilian Emissions Regulations are getting tighter in the coming years. With PROCONVE L7 in Jan-2022 and PROCONVE L8 in 2025, regulated emissions limits will significantly decrease, such as, the NMOG + NOx standard from 130 mg/km (PL6) to 50 mg/km (PL8).This challenge will necessitate better aftertreatment performance, with expected increases the catalytic converter PGM content, and consequently higher system cost. same TWC formulation, as well as, with reduced precious metal content. Prior to testing, all samples were oven-aged at 900°C to represent an end-of-life condition. Emission testing procedures followed the USEPA FTP75 protocols. Results from this study confirmed that the advanced low mass substrate can significantly reduce emissions (THC emissions by roughly 13%) or allow for lower PGM loadings without emissions penalty.

“…From the perspective of sustainable development and environmental protection, many countries have introduced strict policies and emission standards to reduce the consumption of fossil fuels and the emission of motor vehicle exhaust pollutants [8][9][10][11][12]. Researchers are actively looking for ways to reduce pollutant emissions from engines, including engine modifications, vehicle exhaust after-treatment, and improvements in combustion technologies [13].…”

The use of zero-carbon and carbon-neutral fuels reduces emissions of conventional pollutants, but their emissions can be toxic and have various adverse effects on human health. This article reviews the possible combustion products of zero-carbon and carbon-neutral fuels, as well as their cytotoxic effects and potential health risks. At the same time, the review outlines biological models and toxicity detection methods commonly used in pollutant toxicity studies. Metals, nitrogen oxides (NOX), and ammonia (NH3) emitted from the combustion of metal fuels, hydrogen fuels, and ammonia fuels in zero-carbon fuels are harmful to human health. Exhaust emissions from carbon-neutral fuels, particularly biodiesel, and their blends with gasoline/diesel are cytotoxic, leading to severe cellular damage, such as oxidative damage, inflammatory responses, DNA damage, cell death, or apoptosis. Moreover, the normal function of the human body’s respiratory, cardiovascular, immune, digestive, urinary, and nervous systems may also be impacted by these fuel emissions according to cytotoxic research. Cytotoxicity of fuel combustion products is usually related to the fuel type, time, dose, and cell line used in the experiment. This review provides some ideas for the exhaust emission management of zero-carbon and carbon-neutral fuels and human health assessment. It also presents a theoretical and experimental basis for further research, including in vivo experiments.
