Asir Bro, i would like to correct few details presented by you. In BS6.2 diesel engines (mostly >2L), various exhaust processing units will be placed in following order 1. Diesel Oxidation Catalyst/Catalytic converter (this will have temperature & oxygen sensors) 2. Selective Catalytic Reduction (SCR) system (this will be monitored by Nox sensor 3. Diesel Particulate Filter (DPF) (this will have differential pressure sensor & particulate matter sensor). SCR system will only spray urea solution into exhaust stream for Nox reduction and it will not aid in burning the soot particles accumulated in DPF. Only high temperature achieved through passive/active regeneration will burn the soot particles accumulated in DPF.
DPF issues are common for BS 6 vehicles especially Ford Ecosport. Service people say to drive the vehicle continuosly for 50 kmph above. Mileage is also low compared to BS 4
Informative video. தெரிந்த விஷயத்தை ஒரே இடத்தில் உட்கார்ந்து கதைபோல் சொல்லாமல் காரின் under chase பகுதியில் நின்று exhaust spares பற்றி practice ஆன விளக்கம் அளித்துள்ளீர்கள். நல்ல முயற்சி. நன்றி 🎉
I would like to appreciate Bro. Asir for the making and presentation of this video. This video clears that there is a chemistry working between him and chemistry.
Having driven Petrol and Diesel both Diesels are more fun to drive with their torquey nature....petrols on the other end are more silent refined not to mention more environment friendly... BS6 Diesel cannot even beat BS4 Petrol
I am having Tata Altroz Diesel since 2020. Initial 1 year i was facing soot clogging issues frequently and I suffered a lot to understand this DPF issue. later I understood this mechanism, so first thing I stopped using normal Diesel and started using Indian oil Xtra Green Diesel only and I changed my driving style to adapt the car behavior like using low gear in higher RPM in city and take into highway drive for a while. By following this my car forgot to blink soot clogging light past 3 years. 😊 Enjoy the Diesel cars. Happy Motoring 🚗
you could have explained how the combustion mechanism works in petrol engine vs diesel engine. adding to your point further info on how combustion happens, Petrol engines via combustion of petrol fuel (low molecular weight) + air in presence of spark plug to release energy, hence complete combustion to release as gas. however in case of diesel engines it is via compression of diesel fuel (high molecular weight) + air under high compression will auto ignite and release energy hence incomplete combustion, if excess fuel is injected (or for high torque requirement applications more fuel injected) is remaining inside the combustion chamber. hence high carbonaceous material due to compression may not burn fully resulting in soot or carbon black remnants in exhaust gas.
Asir bro..Message came that you had Viral fever. How is it now..The way you presented the video with usual lengthy lecture , it seems you are back to normal.. Main point is if you are going to use the car only in city traffic conditions with mostly slow speeds then passive regeneration is not possible. Only active mode is to be used. If mainly used for long distance driving then it is ok.
Hi brother super explanation about DPF I’m using i20 diesel BS6 sometimes i may receive DPF warning symbol on cluster i will take to high way and drive in high rpm with lower gear within 10-15 mins it will clear even though it is not equipped with ad blue liquid.
Nice content... we are having xuv700 where we littrellay dont know how to maintain such car and its requirement of DPF and all, only short intro was given at car showroom due to excitment we didnt bother much into it. This content really helps ppl and as you mentioned ,now a days disel cars are less polluting than b4 its viable to buy diseal cars instead of ev where we r still at initial stages ppl with lots of options and money can daringly can buy ev's.
Diesel car shld be promoted. Make the infra possible . Govt shld build infra for sure. We pay toll and go and still traffic jam is happening in 4 6 or 8 lane roads..
Excellent content Asir sir.. please keep doing science episodes such as this more often... You are explaining automobile science quite well like velu sir..
one of the best of your videos. you well presented asir. Thank you. want to highlight few things... already diesel engines are so complex and need more maintenance, day by day due to noms we are adding more complex systems in that. Result end user will affect with more cost and etc... with this diesel engine performance now a days turbo petrol engines are serving. why users have to buy this complex systems with more cost. also we are convincing our ecosystem too. already euro countries stopped manufacturing low CC diesel cars...already in india low cc petrol engines 600, 800 cc are stopped. soon below 2.0L cc diesel engines manufacturing will be stopped. for taxi segments CNG's are pushed already. soon in fuel stations in cites diesel filling pumps hoses will be reduced.. so diesel vehicles may wait for long queue and required to fill. and this will replace this with CNGs hoses. also started seeing CNG'S for middle level heavy diesel vehicles in cites... very less time to say bye for smaller cc diesel engines cars...
16:06 actually mahindra provides additional feature . When the cluster shows dpf clog warning , additionally it also shows the option for the user to go for park regen mode .. where the user need to park the car , handbrakes should be engaged and in neutral then starts the park regen mode , the car automatically goes to 2k rpm for around 5mins then 2.5k rpm for some more minutes. Which will cause that optimum temporature to burn particulate matters. This feature actually helps the people who cant take for long trips always. I'm not sure whether it actually works like long run. But somewhats helps.. Lovely content by asir na❤
Awesome content and a need of the hour. Does this mean we don't have to worry about diesel vehicles being phased out by the government or the current manufacturers in the near future? Heard diesel vehicles were banned in some parts of Delhi were there is very high pollution.
Information about PM sensor is wrong: it is used for diagnosing a broken dpf and not for controlling or activating regeneration nor measure PM/soot. Please consider consulting with some experts before posting :)
Adblue dosing is for Nox control not for soot. DPF is only for soot (carbon) traping, regen works only based differential pressure sensor not on PM sensor. Understand the logic behind oxidation catalyst, dpf catalyst and scr catalyst different technologies used to control pollution with the different sensors. Lambda matters more here. EGR is one of the technologies used, there are different aspects to be considered in bs6. Understanding is important before sharing knowledge.
Hi motowagon, Thanks for providing some clarity on this DPF technology. What does ad blue does on these dpf technology? Recently I test drive a latest bs 6 for tuner and enquired it with the service guy but they informed as you need to know to maintain the dpf levels else it will be a issue for you on maintenance. Kindly provide some simple steps to follow on this dpf for all the common people which will be relief for all the diesel lovers 😊 Thanks in advance.

Hi Asir bro, இப்போ 2020 used ford ecosport வாங்கலாமா? ஃபோர்ட் service and spare parts availablity எப்படி இருக்கு? 8-9 lakhs ல ecosport வாங்குவது worth ஆ இருக்குமா? கொஞ்சம் answer பண்ணுங்க

Hello Asir sir, a great fan of your technical knowledge in Automobiles. Our family owns a Nissan Sunny K9K D engine and am a great fan for it in terms of power delivery, fuel efficiency and maintenance and the car itself. Was waiting for the global spec Nissan sunny/Almera/Altima to be launched in India but, was heartbroken to hear the discontinuity of it. Later on seeing your videos I came to know that it's because of K9K couldn't survive BS6. As said by you in this video, suzuki's exhaust structure couldn't stand modification for BS6. What could be the reason for K9K engine in your point of view? Because I am wondering for a long period, how can Mahindra's 2.2L Diesels survive BS6 but not a less capacity engine whose exhaust pollution particles would be less when compared (just my view) couldn't. Happy to hear in any part of your upcoming Podcasts. Thank you Sir. Big fan 🤩.
What about diesel engines with automatic transmission? Because automatic transmission shifts automatically during a certain rpm. Would that mean automatic transmission diesels have no regen issues if do not why? What is the law regarding diesel delete in india? My uncle who has Mahindra marazzo is fed up with the dpf issues.. Also, I wanna contact you regarding something do you have a number? Thanks.
Bro as per my understanding silencer or mufflerum, dpf filterum vera, (dpf filter is a part added to them) silencer or muffler can be without dpf filter aswell.
