What are the effects of a clogged engine exhaust gas recirculation pipe?

Once the engine exhaust gas recirculation pipe is clogged, it can cause a series of problems. Problems caused by clogging: The exhaust gas produced after combustion in the engine combustion chamber needs to be discharged through the exhaust pipe. Once clogged, it can lead to a series of issues, such as engine overheating, backfiring, exhaust pipe rupture. In mild cases, it may cause engine shaking, while in severe cases, it can lead to stalling, difficulty starting, or even failure to start. Effects of a damaged exhaust valve: A faulty car exhaust valve increases emissions, reduces fuel economy, and causes unstable idling. The exhaust valve, also known as a gasoline separator or pressure control valve, is installed between the compressor outlet and the condenser inlet. Through separation, it improves the heat transfer effect between the condenser and the evaporator.
My vintage car once had a clogged EGR tube issue. After driving it for a few years, the engine started gasping for air, idling as shaky as a rusty fan, and acceleration became terribly sluggish. The fuel consumption skyrocketed from 8 liters per 100 km to 12 liters – what a wallet-crusher! At the repair shop, the mechanic explained that the blockage prevented exhaust gas recirculation, leading to thickened carbon deposits inside the engine, increased temperatures, and accelerated wear. If left unfixed, it could fail emission tests, get stuck during annual inspections, or even damage the catalytic converter. Since then, I’ve been using cleaner on the intake ports every six months to avoid a repeat disaster.
