Optimized Exhaust Gas Treatment for lower emissions & improved efficiency
Boost your exhaust gas treatment system with our advanced air control valves, designed to enhance operating efficiency and reduce emissions. Our innovative solutions regulate the flow of additional air into the exhaust system, accelerating catalytic converter heating for cleaner vehicle startups.
Modern catalytic converters require temperatures of around 200°C to function effectively. During cold starts, engines run with excess fuel to ensure smooth operation and prevent misfiring. By introducing precisely controlled air, our valves enable hydrocarbons to react exothermically, reducing warm-up times and lowering harmful emissions from the start.
With a scalable, modular design, Solero’s valves integrate seamlessly into various engine configurations. Suitable for both diesel and gasoline applications, they enhance catalytic converter efficiency, supporting cleaner emissions and improved environmental performance. Upgrade your exhaust gas treatment system today and contribute to a greener future.
Working principle
Air Supply for Faster Catalyst Heating
Exhaust air control valves play a crucial role in optimizing catalytic converter performance by precisely regulating the flow of additional air into the exhaust system. Their function is essential in the early stages of engine operation, particularly during cold starts when emissions are at their highest.
During a cold start, engines operate with excess fuel to ensure smooth running and prevent misfiring. However, at lower temperatures, the catalytic converter is not yet fully effective in reducing harmful emissions. The exhaust air control valve introduces a controlled amount of additional air into the exhaust stream, enabling an exothermic reaction with unburned hydrocarbons. This reaction generates heat, allowing the catalytic converter to reach its optimal operating temperature of approximately 200°C more quickly.
System Integration
By precisely controlling airflow, the valve ensures that excess fuel from cold starts is efficiently utilized to heat the catalytic converter rather than being emitted as pollutants.
