We remove the EGR, the intake manifold, and the throttle body, mechanically cleaned the carbon build-up, and put everything back. While this servicing is inevitable in high-mileage Direct Injection (DI) engines. What's strange is that this car has done less than 40K kms. ๐๐ผ๐ ๐ฑ๐ถ๐ฑ ๐๐ต๐ถ๐ ๐ต๐ฎ๐ฝ๐ฝ๐ฒ๐ป ๐ถ๐ป ๐ฎ ๐น๐ผ๐-๐บ๐ถ๐น๐ฒ๐ฎ๐ด๐ฒ ๐ฐ๐ฎ๐ฟ? ๐ฅ๐ฒ๐ฎ๐๐ผ๐ป #๐ญ: The EGR or Positive Crankcase Ventilation (PCV) systems might be defective or poorly designed off the bat. Premature profound carbonization is often symptom of a problem with PCV or EGR. ๐ฅ๐ฒ๐ฎ๐๐ผ๐ป #๐ฎ: Insufficient highway driving. If you don't drive on the open road for about 30-60 mins every fortnight, your engine oil is going to get pretty dirty byย blow-by, especially in a diesel engine, which does a lot more volume of EGR.ย Short trips and cold starts exacerbate the formation of sludge in the inlet system and once it's there, it stays. However, highway driving does not clean up any contaminationโ mechanical cleaning is the only remedy. Cars that donโt get a lot of highway driving should have engine oil changed twice a year instead of annually. ๐๐ฎ๐ป ๐ณ๐๐ฒ๐น ๐ฎ๐ฑ๐ฑ๐ถ๐๐ถ๐๐ฒ๐ ๐ฝ๐ฟ๐ฒ๐๐ฒ๐ป๐ ๐๐ต๐ถ๐? No. In a DI engine, fuel is directly injected into the combustion chamber and is thus completely separate from the inlet air system until the the inlet air gets into the cylinder. Fuel additive in a DI engine never physically interacts with the inlet air system. ๐ช๐ต๐ ๐ฎ๐ฟ๐ฒ ๐บ๐ฎ๐ป๐๐ณ๐ฎ๐ฐ๐๐๐ฟ๐ฒ๐ฟ๐ ๐ผ๐ฝ๐๐ถ๐ป๐ด ๐ณ๐ผ๐ฟ ๐๐ ๐ฒ๐ป๐ด๐ถ๐ป๐ฒ๐ ๐ถ๐ป๐๐๐ฒ๐ฎ๐ฑ ๐ผ๐ณ ๐ฝ๐ผ๐ฟ๐ ๐ณ๐๐ฒ๐น ๐ถ๐ป๐ท๐ฒ๐ฐ๐๐ถ๐ผ๐ป? Because DI engines are more efficient and responsive. They offer better better fuel economy and lower emissions. ๐ง๐ฎ๐ธ๐ฒ ๐ฎ๐๐ฎ๐: Sadly, complexity is the enemy of reliability. In this case, highway driving is the primary line of defense. . . . . #directinjection #portinjection #cars #diesel #petrol #gasoline #engines #emissions #exhaustgases #egr #manandmachine #justkeepdriving (at Hyderabad) https://www.instagram.com/p/CHU-GHOJvmU/?igshid=yv0nk8rhrtzz
