EGR valves/throttles

EGR throttle

In today’s automotive market, exhaust emission standards play a key role. Vehicle manufacturers are forced to develop innovative solutions to reduce emissions of harmful substances. One of such solutions is the EGR valve

The EGR (Exhaust Gas Recirculation) throttle is responsible for recirculating part of the exhaust gases from the exhaust system to the engine intake system. Its goal is to reduce emissions of nitrogen oxides (NOx), which are one of the main air pollutants emitted by vehicles. The throttle is equipped with a modulator that allows precise control of exhaust gas recirculation depending on current driving conditions and engine requirements.

The operation of the EGR valve is extremely complex. At low engine speeds, the modulator controls the opening of the EGR throttle, allowing more exhaust gases to be recirculated. As a result, the combustion temperature is lowered, resulting in reduced nitrogen oxide emissions. At high engine speeds, the modulator reduces the opening of the EGR throttle, reducing exhaust gas recirculation and providing greater engine power and flexibility.

EGR throttle – benefits

The EGR valve has several significant benefits. Firstly, it contributes to meeting stringent exhaust emission standards. Thanks to precise control of exhaust gas recirculation, it is possible to reduce nitrogen oxide emissions, which translates into cleaner air and better environmental quality.

Secondly, the EGR throttle with modulator affects the vehicle’s performance. Correct adjustment of exhaust gas recirculation to driving conditions translates into greater power, torque and engine flexibility. Thanks to this, the vehicle can provide high efficiency and driving comfort both on long routes and in urban conditions.

It is also worth mentioning the economic benefits. Reducing nitrogen oxide emissions allows for compliance with exhaust emission standards, which may result in lower ecological road tolls and tax breaks, which translates into lower vehicle operating costs.

Arcoore EGR valve

The EGR valve is designed for reliability and durability. Components are carefully well-fitted and constructed from high-quality materials to ensure optimal performance and minimize the need for maintenance.

However, it is worth remembering that the damper, like any advanced technology, may require periodic maintenance and cleaning. Accumulation of soot, oil or other contaminants may affect its performance and effectiveness. Therefore, it is important to regularly monitor the condition of the EGR valve as well as its maintenance and cleaning.
