How to Clean a Car's GPF?
1 Answers
Cleaning a car's GPF depends on the situation: 1. If the indicator light is green, drive more on highways to allow the GPF to handle the deposited particles by itself; 2. If the light is yellow, increase the exhaust temperature to burn off the carbon deposits. Here is more information about the forms of GPF in gasoline engine exhaust pipes: 1. GPF is installed integrated with TWC, close to the exhaust pipe. 2. GPF is installed downstream of the TWC. 3. A four-way catalyst is formed by coating the three-way catalyst on the GPF substrate. 4. After prolonged use, a PM layer will form on the surface of the GPF, causing a throttling effect in the exhaust pipe, increasing exhaust resistance and fuel consumption.
