Valve, causes a claggy, sticky, build-up of Carbon that eventually solidifies over time.

How does exhaust gas recirculation ( EGR ) reduce NOx emissions?

Exhaust gas recirculation (EGR) is the most common technology to reduce nitrogen oxides (NOx) emissions on diesel internal combustion engines (ICE). EGR takes exhaust gases from the exhaust manifold and reintroduces them into the intake manifold, mixing them with fresh air. By doing this, the main ingredients of NO x emissions are reduced:

Why does an EGR cooler lower the temperature of exhaust gas?

The EGR cooler (radiator) lowers the temperature of the exhaust gas before it is introduced into the air charge stream. The lower the temperature, the higher the density, the better the efficiency in reducing the NO x emissions.

How does the EGR valve position sensor work?

The position sensor of the valve is linear and provides a signal proportional to its supply voltage (usually 5V). The EGR valve position sensor signal is set to increases in the direction of the opening of the valve. The position sensor is used for three main reasons:

What happens if you have a bad EGR valve?

When the valve is opened, exhaust gases are allowed through the vehicle’s EGR system to help control vehicle emissions. When the EGR valve has an issue, it can cause problems with the flow and operation of the EGR system, which can lead to increased emissions and performance issues. Usually, a bad or failing EGR valve will produce any these 4…
