In a recent video that was shared online a mechanic shows how badly the intakes, Turbo as well as the EGR valve of a Honda Diesel Engine were filled up with soot. This has not been the only video that has showcased such issues with the BS6 engines, there have been loads of videos where similar issues were showcased in Diesel Engines.

To find out the reason behind such accumulation of soot in engine internals we have carried out an indepth research into the issue. Here are a few of the complications that would arise if your diesel vehicle has such issue.

low acceleration and heavy smoke during downshifting struggle while the vehicle is in high gears these are some of the most evident complications. This problem is being reported quite regularly in the new BS6 diesel engines that are currently on sale. Here are a few issues that might have been the reason behind such problems.

Oil Dilution- The Reason Behind DPF Clogging

BS6 engines that have been manufactured with late post Injections usually suffer from such problems as Engine oil dilution. Late Fuel Post Injections are some of the most commonly used technology that are used by manufacturers to provide the vehicle with a High Exhaust temperature necessary for active regeneration of DPF filters. Most new engines that have active DPF regen have such late fuel post- injections.

Oil Dilutions often cause the performance to drop and engines to fail. Beyond this vehicles that do not have any NOx Storage Catalyst often suffer from such issues as well.

Active Regeneration For DPF In Diesel Engines

The modern BS6 engines have been adapted in such a manner that they go through constant regeneration even while driving. Regeneration is achieved by High Exhaust temperature for which Late Post Injectors Continuously inject a small amount of fuel after the main cycle of combustion. Hence it can be said that the features that facilitate Regeneration of DPF filters also cause the engine to have Oil Dilution.

BS6- Time Duration Of The Engine Regeneration

While these late injections might not cause issues when the vehicle is new, over time with frequent cycles they might face oil dilution that affects the over all performance. Most of the times these late post fuel injections are timed to be closer to the exhaust valve opening during the expansion stroke.

BS6 Known DPF Issues

Users who have been primarily using their diesel vehicles in the city have reported increased instances of performance drop. As per the reviews it has become quite clear that while being driven in the city limits Diesel engines DPF filters would get clogged and cause the vehicles to loose their performance.

How To Check DPF Issues

If your vehicle has been showcasing similar signs of low performance we would recommend that you get your intakes, and EGR valve checked. Or you can opt for Endoscope camera test of your engine where the whole engine is reviewed by a small camera to check for any accumulations as well as other kinds of deposits on the walls of the cylinder as well as the head of the engine.
