The Setting
While I have been very choosy and skeptical about the aftermarket car detailing and modifications store, for the first time ever I took my car to an aftermarket care, but this time unlike myself - this was more of an experiment.
All this happened when my friend and his family moved into my nearby apartment and since we both speak a lot about cars and their maintenance - we obviously moved to this topic of the black smoke coming out of both our Ford TDCi. Both our cars are almost of the same age and have clocked 57K and his with 65K respectively.
While I have been very cautious and curious of the dipping oil levels from the engine of my EcoSport, he was more concerned about the Carbon leftovers within his Fiesta Classics exhaust.
Twist
My recent visit to the Ford ASS justified my suspected high oil consumption, and on acceleration - could see a high level of black smoke from the exhaust which is not comforting. Added to this - I have made up my mind to get the overhaul done - targeting a replacement of my engine block assembly with piston and rings provided I get some good Goodwill assistance from the company. (This should go to some thread soon)
While I have been suspecting, my driving style and of course my misfortune I started feeling like my engine is not breathing as it should, and hence went by friends suggestion on get the carbon cleaned through these guys called Car Cardiac Care, who are there Cochin. As my planned date of visit to Ford ASS to get the engine diagnostics was monday which is still a few days ahead - I went to the cardiac care to get some carbon out as I wait for a deeper diagnostics.
After doing a detailed study on facebook through customer reviews and a couple of Media coverage on the same enterprise I gave them a message, and they politely responded to me with a call fixing an appointment.
Visit
Next day morning 19th July, I drive down there drenched in rain, with my thoughts of low compression - i really started feeling my car is not breathing properly, which only made me get this decarbonation mandatory - despite the fact that my car might get an engine overhaul. I didnt have sufficient understanding or knowledge to judge when would be the right time to do it - is it before the overhaul or is it later. But I said lets get this done - probably this would be the right time to get this done.
Drove down to this "ok" place which was merely a neat garage with a couple of mechanics and two other cars around "Both belonged to the staff there", I had a warm welcome and they gave me an overview of what would happen during the next 30 mins.
They simply opened my air intake pipe and plugged in the device - which would push in Hydrogen and Oxygen into the engine for the next 30 mins, set on the device. The 30 mins was decided based on the size of my engine and of course my ODO reading. For cars above 1L it would take some 45 mins based on my understanding.

The monitor on top of the machine that pumped Oxygen and Hydrogen

They have removed the metal connector on top of the intake and have placed this hose with its cap reducing impurities flowing in
All this is with an idle engine and the variation in the sound was visible probably from the 10th or 12th mins since the pump in started. I could not spot anything on the exhaust pipes as yet, but the variation in noise was visible (Probably I started paying more attention to the engine noise since oil level came down). Now post the 30th minute, they closed the system and switched off my vehicle to do a test drive. They did not do a pre-test drive though.

Yes, just this thin pipe doing all the job.
The technician got into the car and started driving this for about 5 kms from the place, and he was trying to burn more carbon out by revving the engine beyond 2K to within 3K rpm, and he said the car doesnt feel any choking and he added that I should be able to judge it more clearly.
The Result
After for about 5 KM, I got into the driving seat, and I drove like I used to drive but added some load on the engine to test its change. To my shock (and hope I am better right here) I could see that
1) Visible variation in the engine noise (with glasses down / no AC / No Music) and probable I felt the car was breathing quite well.
2) Though not remarkable the accelerators responsiveness was quite improved in comparison to the last say 4-5K I have driven. I felt like the car had gained some fresh air in the way it drives now (of course not so remarkable).
Now that my car is going to the garage next Monday, my next visit there would be with my friend and his car. But I still feel that my general feedback or judgement would come only post about a day of driving - or may be at least 50K. I feel the effort is quite work the 3K spend on the car, which I would do again in my next 35K.
