The Ger­many-based SEG Au­to­mo­tive, man­u­fac­turer of starter mo­tors, elec­tri­fi­ca­tion com­po­nents and gen­er­a­tors, is work­ing on sev­eral new prod­ucts for im­prov­ing fuel econ­omy and in turn re­duc­ing CO2 emis­sions. Re­cently, the com­pany launched a whitepa­per which dis­cusses ve­hi­cle pol­lu­tion that has been im­pact­ing coun­tries, in­clud­ing In­dia, and of­fers so­lu­tions to ad­dress the prob­lem ef­fec­tively. The pa­per also dis­cusses en­gine ef­fi­ciency strat­egy for In­dia that fo­cuses on mild hy­brid tech­nol­ogy for com­pact cars and light com­mer­cial ve­hi­cles.

SEG Au­to­mo­tive was es­tab­lished in 1913 as part of the Bosch group to man­u­fac­ture gen­er­a­tors, reg­u­la­tor switches and head­lights. SEG Au­to­mo­tive In­dia, the com­pany’s In­dian arm founded in 1989 as Bosch Ltd, was one of the first lo­cal com­pa­nies to pro­duce starter mo­tors and gen­er­a­tors in In­dia. In Jan­uary 2018, SEG Au­to­mo­tive was ac­quired by Zhengzhou Coal Min­ing Ma­chin­ery Group Co (ZMJ). It now op­er­ates as an in­de­pen­dent com­pany. The com­pany has 3 man­u­fac­tur­ing fa­cil­i­ties each in Na­ganatha­pura and Has­san, in Kar­nataka, and in Chen­nai.

Ac­cord­ing to Anil Ku­mar MR, Man­ag­ing Di­rec­tor & Pres­i­dent, SEG Au­to­mo­tive In­dia, “The in­ter­nal com­bus­tion en­gine (ICE) cou­pled to highly ef­fi­cient start/stop mo­tors and ad­vanced mild hy­brid driv­e­trains is the best op­tion to go with and to re­duce sig­nif­i­cant amounts of CO2 emis­sions dur­ing the life cy­cle of pas­sen­ger cars and light com­mer­cial ve­hi­cles in In­dia.”

SEG Au­to­mo­tive In­dia pro­vides so­lu­tions for all seg­ments of the au­to­mo­tive in­dus­try in­clud­ing three-wheel­ers, pas­sen­ger cars, com­mer­cial ve­hi­cles, offhigh­way ve­hi­cles, sta­tion­ary en­gine ap­pli­ca­tions, and across all drive tech­nolo­gies.

The com­pany be­lieves that though there are talks of com­plete elec­tri­fi­ca­tion be­tween 2025 and 2040 as a part of the Paris dec­la­ra­tion, that will hap­pen only in phases. “The main trend (guid­ing prod­uct devel­op­ment) is the CO2 re­duc­tion which is driv­ing our prod­uct port­fo­lio and 2025 is a mile­stone. We see in­di­ca­tions to this from some gov­ern­ments and dis­cus­sions in the re­gions where the new mile­stone re­gard­ing the CO2 tar­get is set. If you fol­low the Paris dec­la­ra­tion tar­gets, then by 2025 elec­tric ve­hi­cles will still have a mar­ket share of about 15%, which means that 85% of the cars will still have com­bus­tion en­gines. And, hence, we need to do some­thing about that, and in­crease the ef­fi­ciency of in­ter­nal com­bus­tion en­gines,” Juer­gen Sch­nei­der, Vice Pres­i­dent Tech­nol­ogy and Prod­ucts, SEG Au­to­mo­tive Ger­many GmbH, said.

The In­dian au­to­mo­tive in­dus­try will be mov­ing to BS-VI norms

in 2020. SEG, with its global ex­pe­ri­ence in of­fer­ing so­lu­tions to Euro VI ve­hi­cles, has al­ready started its work on BS-VI with the In­dian man­u­fac­tur­ers to make them fu­ture-ready. “Be­ing a Tier 1 sup­plier with a fo­cus on fu­ture tech­nolo­gies, we are work­ing for an­other big chal­lenges com­ing in by 2022 in the form of CAFE norms. We have al­ready be­gun the dis­cus­sion with our cus­tomers to reach the fleet av­er­age of 113 gm per km. There are sev­eral tech­nolo­gies which work in com­bi­na­tion in­clud­ing high ef­fi­ciency of gen­er­a­tors, start-stop tech­nol­ogy of starters and also the use of mild hy­brids. Be­ing a full-line prod­uct sup­plier, cus­tomers would get the right choices to select the best suitable one,” Ku­mar said.

SC60 starter mo­tor

In or­der to re­duce CO2 emis­sions the com­pany is ready with its new SC60 starter mo­tor. This 2.2kg mo­tor can re­duce up to 8% CO2 emis­sion and fuel con­sump­tion in com­pact cars. The mo­tor au­to­mat­i­cally shuts down the en­gine when the ve­hi­cle idles, hence re­duc­ing fuel con­sump­tion and im­prov­ing the over­all fuel econ­omy. This is achieved with the help of sen­sors at the ped­als and the crankshafts. The en­gine can be in­stantly reignited by press­ing the clutch, avoid­ing the has­sle of go­ing through a con­ven­tional ig­ni­tion method. SC60 start-stop

starter mo­tor, with re­li­a­bil­ity of more than 250,000 start­ing cy­cles, is an ideal fit for the small petrol and diesel en­gines in the In­dian mar­ket to re­alise the ben­e­fits of the starts­top func­tion. SEG cur­rently man­u­fac­tures this starter mo­tor lo­cally with high lo­cal devel­op­ment and ap­pli­ca­tion con­tri­bu­tion.

About the com­pany’s new SC60 Start/Stop mo­tor, Ku­mar said, “We in­tro­duced Start/Stop tech­nol­ogy first in In­dia in 2008. How­ever, it was mostly fit­ted in larger cars. The new SC60 mo­tor has been de­vel­oped fo­cus­ing the In­dian mar­ket for smaller com­bus­tion en­gines: it is among the small­est of its kind in the world and can be fit­ted on to com­pact cars, yet it pro­vides up to 1.2kW start­ing power.”

48V Boost Re­cu­per­a­tion Ma­chine

SEG is also bet­ting big with its new 48V Boost Re­cu­per­a­tion Ma­chine (BRM) for diesel hy­brids. This mo­tor, when cou­pled to an ICE, uses brake force re­cov­ery tech­nol­ogy to charge a 48V lithium ion bat­tery. It con­verts the ki­netic en­ergy pro­duced by brak­ing to elec­tri­cal en­ergy, which then is stored in the bat­tery. This stored en­ergy func­tions as a ‘torque booster’ to re­duce the turbo lag from diesel mo­tors and it can even be em­ployed in an ad­di­tional ‘Coast­ing’ func­tion for re­laxed yet ef­fi­cient driv­ing. Ac­cord­ing to the com­pany, the 48V BRM can pro­duce as much as 10kw (13bhp) and 56Nm of torque from 12kw (16bhp) of en­ergy re­cu­per­a­tion.

BRM em­ploys the brak­ing force re­cov­ery tech­nol­ogy (re­cu­per­a­tion) fa­mil­iar from For­mula 1 to re­duce fuel con­sump­tion by up to 15%. In the medium term, 48V will be in­dis­pens­able for achiev­ing CO2 emis­sion tar­gets - af­ter all, 85% of new ve­hi­cles will still be equipped with an in­ter­nal com­bus­tion en­gine even in 2025. The so­lu­tion also proves ben­e­fi­cial for con­sumers - in con­trast to EVs and PHEVs, the cost of the unit is re­cov­ered through fuel sav­ings. BRM is a cost-ef­fec­tive and easy-to-im­ple­ment mild hy­brid so­lu­tion, as it re­places to­day’s gen­er­a­tor at its ac­tual lo­ca­tion in the drive belt. In the case of re­gen­er­a­tive brak­ing, where the bat­tery gets charged dur­ing brak­ing, the BRM uses the charged en­ergy to boost the IC en­gine when needed. The BRM also en­ables the coast­ing fea­ture, where the ICE/elec­tric mo­tor is turned-off above a cer­tain speed and the BRM pro­vides enough en­ergy stored in the bat­tery ear­lier to counter fric­tion forces and wind, to keep the ve­hi­cle mov­ing at a con­stant speed. These so­lu­tions help re­duce CO2 emis­sions by up to 15%, Sch­nei­der ex­plained.

Re­plac­ing ICE is still a big chal­lenge. It re­mains doubt­ful whether this is pos­si­ble be­yond a premium seg­ment less in­clined to e-mo­bil­ity. E-mo­bil­ity is not go­ing faster be­cause many peo­ple are not buy­ing EVs. The SEG white pa­per has iden­ti­fied 2 main present per­sonal dis­ad­van­tages: high ac­qui­si­tion cost, and lim­ited charg­ing in­fras­truc­ture. In ad­di­tion to these are the risk fac­tors of un­cer­tain re­sale value, range re­stric­tions and long charg­ing time.

Talk­ing about the elec­tric mo­bil­ity, Sch­nei­der said, “The re­duc­tion of CO2 will drive a change in mix of mo­bil­ity. We can­not rely to­tally on EVs for mo­bil­ity. There will be change to­wards elec­tri­fi­ca­tion. But it will be step by step. While elec­tric cars will be used for shorter dis­tances and in some other cases, longer dis­tance could still be cov­ered by ICE or hy­brid ve­hi­cles.”
