Does a Diesel Vehicle Consume More Fuel When the EGR Valve is Clogged?

[JulietteMarie]

Diesel vehicles do not consume more fuel when the EGR valve is clogged. Below is relevant information about the EGR valve: 1. When the EGR valve is clogged, the amount of engine exhaust decreases, leading to an increase in the volume of fresh air. For the mechanical system, this results in improved engine performance and better fuel efficiency; 2. The EGR valve (Exhaust Gas Recirculation valve) is a mechatronic product installed on diesel engines to control the amount of exhaust gas recirculated back into the intake system. It is typically located on the right side of the intake manifold, near the throttle body, and is connected to the exhaust manifold via a short metal pipe. Its function is to regulate the amount of exhaust gas entering the intake manifold, allowing a certain quantity of exhaust gas to flow back into the intake manifold for recirculation.
