On August 15, 2026, the Ecological Environment Code of the People’s Republic of China officially came into effect. This is not simply a new “emissions standard” to be met. Instead, it represents a fundamental systemization of air pollution control, mobile source management, emission control systems, fuel and additives, production and sales, in-use maintenance, recalls, testing […]
The Evolution of Diesel Emission Control Diesel engines have long been the workhorses of heavy-duty transportation, agriculture, construction, and marine applications. Their efficiency and durability are unmatched – but their lean-burn combustion produces two pollutants that are particularly challenging to control: particulate matter (soot) and nitrogen oxides (NOx). Unlike gasoline engines, which can use a […]
The Heart of Gasoline Emissions Control The three-way catalytic converter (TWC) is arguably the most important emissions control device ever invented. Since its introduction in the 1970s, it has prevented billions of tons of pollutants from entering the atmosphere. Yet despite its decades of service, the TWC remains a marvel of chemical engineering – a […]
The Dawn of a New Emissions Era The European Union has officially ushered in a new era of vehicle emissions regulation with the publication of Regulation (EU) 2024/1257 on May 8, 2024. Euro 7 represents the most ambitious and comprehensive emissions standard ever developed, covering not just tailpipe pollutants but also brake dust, tire wear, […]
