Dynapachas been at the forefront of imagining the future and bringing in sea-changesand innovations that truly matter in the long term, writes Vishwesh Rai. And, so, complying with CEV Stage IV norms is more ofan opportunity rather than a challenge.

“Dynapachas come up with concept of ‘Cleaner, Greener, Smarter’. We have extensiveknowhow of implementing these solutions in Europe as well as North America andhave capitalized on it while introducing Soil Compactor model CA305 and Tandem Roller model CC425 CEV Stage IV with new features.”

From1^st of April 2021, India will have to comply with the new CEV stageIV regulations for all Construction Equipment Vehicles. This is a welcome move,and is a radical change indeed.

Thischange is the gateway to cleaner air, greener environment, and smartertechnology. It will bring in great sustainable environmental benefits.

Thenew CEV IV engine technology will come with engines that have many electronicupgrades, through which machines could offer extensive communication interface.The new CEV stage IV engine with Selective Catalytic Reduction (SCR) pairedwith Exhaust Gas Recirculation (EGR), offers excellent emission standards thathas lower NOx emission as well as 90 per cent lower particulate matters in theexhaust. Effectively, the air quality will improve so that everyone can breathefresh and easy.

Froma definitive start and many significant intermittent stages after that, we havenow reached this stage. So, what is the background and origin of thispath-breaking move? When and where did it all start from?

Indiais a signatory to the Paris climate agreement and has put forth emissionstandards for Construction Equipment vehicles or, in short, CEV, from 2007. The ParisAgreement is an international treaty on climate change, adopted in2015, covering climate change mitigation, adaptation, and finance.

TheAgreement was negotiated by 196 parties at the 2015 UnitedNations Climate Change Conference near Paris, France. The key objectivesof this agreement were – to keep the rise in temperature under control, toreduce the impact of climate changes, and to minimize the emission levels asmuch as possible.

So,India is bound to take concrete steps towards the hypothetical target of ‘zeroemission’ and, hence, the Indian Government has initiated the strictimplementation of CEV stage IV regulation norms from 1^st April 2021.This initiative has many environmental benefits and other subsequentadvantages.

We,across our global network, were amongst the first to accept and internalizethese changes. We have initiated the implementation of CEV IV norms and ourmany flagship products are now compliant to stage IV.

Dynapachas come up with concept of ‘Cleaner, Greener, Smarter’. We have extensiveknowhow of implementing these solutions in Europe as well as North America andhave capitalized on it while introducing Soil Compactor model CA305 and Tandem Roller model CC425 CEV stage IV with new features.

Wehave packed our machines with special features, like Smart fuel saving,Automatic vibration control, Digital LED colour display, LED working lights,etc. The Tandem Roller CC425 is modified with attractive look and improveddesign to provide better visibility and comfort for the operator that will helpcustomers to work efficiently.

Wehave two objectives in front of us:

• Targeting ‘near zero’ emissions

• Reduce PM (Particulate Matter) emission by 90per cent and NO_x (Oxides of Nitrogen – NO and NO₂) by 80per cent.

Otherharmful elements we are trying to reduce are CO – Carbon Monoxide, and HC –Unburned Hydrocarbons. Our main focus would be on few ‘After Treatment Systems’which are briefly described below.

Exhaust Gas Recirculation:EGR works by recirculating a portion of an engine’s exhaust gas back to theengine cylinders. This dilutes oxygen in the incoming air stream and acts as anabsorbent of combustion heat to reduce peak temperature in cylinder.

Diesel Oxidation Catalyst:DOC is a device that consists of a canister containing a honeycomb likestructure or substrate. The substrate has a large surface area that is coatedwith an active catalyst layer made of Palladium and Platinum (CatalyticConverter).

• As the exhaust gases traverse the catalystoxidation occurs.

• Oxidation catalysts can reduce more than 90 percent of the CO and HC emissions.

Selective Catalytic Reduction:SCR is a simple after treatment system which converts NO_x in theexhaust stream into harmless gases.

Diesel Exhaust Fluid or AdBlue: Thisis a non-toxic solution of purified water (67 per cent) and Urea (33 per cent).DEF from a storage tank is injected into the exhaust stream, and the exhaustand finely atomized DEF enter the SCR catalyst chamber together.

Construction and Agriculture Vehicles

InSeptember 2020, the agricultural machinery (Trem) and construction equipmentvehicles (CEV) norms were separated, new terminologies were introduced, and thecompliance dates were delayed. The new terminology replaces Bharat Stage(CEV/Trem)-IV and Bharat Stage (CEV/Trem)-V with Trem Stage-IV and Trem Stage-Vfor Agricultural Tractors and other Equipment, and CEV Stage-IV and CEV Stage-Vfor Construction Equipment Vehicles.

Encouraging upgradation to CEV Stage IV

Theseinnovations will ask for higher investment, but this will come with many addedtechnical advantages and will ensure desired results in reduced carbonfootprint and cleaner environment. To support our customers, Dynapac is alreadyrunning many projects in India with annual maintenance contract to ensurebetter uptime as well as long machine lifetime.

Thedesign also focuses on upgradation. It is in terms of common/interchangeableparts on CEV stage IV machines so that the unit does not need additional partsstock for fleet owners.

Dynapacmachines are built to last and, hence, we try to offer our machines a secondlife. So, we will support customers who would like to upgrade their BSII orBSIII machines with our new CEV stage IV machines.

Nowonder then that we were amongst the first ones to embrace this change, becauseat Dynapac, we are always at the forefront of imagining the future and bringingin sea-changes and innovations that truly matter in the long term. Moreover, wehave the world-wide experience of accepting the new developments and updatingour range of products according to it.

Justto let you know, we have already adopted CEV IV compliances to a few of ourstar performers in the category of Soil Compactors, Tandem Rollers and Pavers.

“CEVstage IV is an opportunity to upgrade to a Cleaner, Greener, and Smarter India!

Changingfor better is in Dynapac’s DNA. Since last eight decades, Dynapac has alwaysbeen at the forefront of sensing the environmental, technological anddevelopmental changes. And, we are also the first to fully operationalize thesechanges in our widest range of products and other offerings.

CEVstage IV is not new to us. Dynapac’s think-tank and the advanced R&Ddepartment were on it since quite long. Again, we are the first to introduceour series of CEV IV compliant Soil Compactors, Tandem Rollers, and pavers. Thesemachines are all set to raise the bar.

Thisis because we don’t take these changed norms as statutory compulsions. In fact,we look at them as an opportunity to upgrade to superior machine performance,advanced control mechanisms, better fuel efficiency, and enlarged profitmargins for our customers!

Wewould also like to introduce and launch our light compaction range of ourproducts to augment our vision as partner on the road ahead for allstakeholders of the company. In Light Compaction Equipment, we are offeringWalk behind Roller, Plates, Rammer, and Cutter.
