Hey RSM thanks for the updated figures!! Bikes the FE seems to be almost on par with the regular usage. But cars there seems to be lots of variations!!

ARAI Claimed Mileage Figures of Indian Cars

Hello friends, we all have heard about ARAI. It is very common now a days for manufactures to claim that they have an ARAI certified mileage of X km /l.

Now, what do they actually do apart from, well....checking mileage?

Yesterday, I was lead to this particular page on the ARAI website from a comment in a link that Visran posted in the Force One thread (http://www.theautomotiveindia.com/forums/newreply.php?do=newreply&p=235052)

It appears that they are actively involved in product development including engines.

Do any of you guys have any idea if one of these engines are being used in a production vehicle?

May be someone from Pune can throw some light on ARAI.

Re: ARAI Claimed Mileage Figures of Indian Cars

Dear Vinu,2011 jan report of Times of India about ARAI engines,which may give you some idea.
PUNE: City-based the Automotives Research Association of India (ARAI) has developed three high-power engines for the commercial vehicles segment which have evoked interest from several original equipment manufacturers (OEMs) from India and abroad.

Shreekant Marathe, director, ARAI, told the media on Monday that the organisation has developed the engines using in-house design and engineering capabilities. "The engines are now industry-ready and a few OEMs have shown interest in acquiring the design and technology from us," Marathe said.
He said a 6-cyllindar engines that runs on a combination of hydrogen and compressed natural gas (CNG) has been developed by the ARAI team. The engine can meet emission targets set by Euro 5 norms and can be relevant for OEMs in heavy or light commercial vehicles, sports utility vehicles and three-wheelers, Marathe said.

Another engine which will use homogenised combustion compression ignition technology is ready and it meets the Euro 4 emission norms. This engine is suitable for generator sets and heavy and light duty engines and offer diesel efficiency with CNG, Marathe said.

The third is a smaller, 3-cyllindar CRDI engine that meets Euro 4 and Euro 5 norms and is suitable for small passenger cars. The engine is used for manufacturing much heavier engines but ARAI engineers have adapted it for smaller capacity engines, said A V Mannikar, deputy director, ARAI. He said the engine is prototype-ready and will soon further undergo developments.

Marathe said the ARAI has successfully completed 'Size India' project to meet automotive industry's long-standing demand for large and robust anthropometric database representing civilian population to be used in automotive design.

The database now has over 5,000 scanned samples which can offer information on over 250 points and has been very popular with design houses and automotives manufacturer, he added.

Thanks Thenali, this has evoked interest in me as well. I wonder whose those OEMs are

ARAI’s 1,500-cc engine to be ready for sale in October - Indian Express

ARAI’s 1,500-cc engine to be ready for sale in October
The Automotive Research Association of India (ARAI) will finally make its 1500 cc engine, which is under development, ready for sale to automotive companies by October this year. It had been on the anvil for the past three years.

The first stage of the project will see development of an engine capable of producing 50 KW per litre power and its deployment in vehicles will help people reduce emission and fuel consumption.

A team of 15 engineers are working on the project, which will be completed by the third quarter of this calendar year. It will be offered to companies the following month. N V Marathe, Head of Powertrain Engineering department of ARAI who is leading the research on the project said that in the first stage, the engine will produce a power density of 50 KW per litre.

He added that in subsequent stages, the engine will be developed with a higher power output that can reach upto 75 KW per litre. The 3-cyllinder engine will be used in small cars and light commercial vehicles, but its variants of two and four cyllinders would be developed in later stages that could also be deployed in larger cars.

“The engine prototype is ready and performance and combustion tests on the dynamometer have commenced. The experimental optimization through engineering approach will be carried out to achieve the first of the performance targets of 50 KW per litre and Euro 4 and Euro 5 emission levels. The emission development on the prototype would be complete towards the end of third quarter of this calendar year and the design will be offered to automotive companies by October,’ said Marathe.

Senior deputy director of ARAI, D J Kulkarni, said the decision on commercial exploitation of the product will be taken only after its completion. “We can license the design of the product but the final decision will be taken only after the project is completed,” he said.

ARAI has worked on the downsized model of engine development ensuring that there was no impact on power output and generation of required torque for smooth driving.

The technological challenge is to meet the desired power and torque requirements from the downsized engine as aggressive downsizing increases load on the engine. The basic concept of downsizing is to make the engine displacement smaller for the required power output. Smaller cylinder displacement also means thermal loss which is a big technological challenge,” said Marathe.





Mods: I do not know why you put such a misleading title [;)]
