Its a start I wasn't aware of. Kirloskar is an Indian heavy weight that doesn't get much attention here at the forum but I read a lot and foundsome intersting facts. They built the First Listeroid in 1946 the fist Petter AV1 in 1949. They've been in bed with Cummings, Briggs & Stratton and now Toyota. And now it would apear they are prepring to enter the US market. The question is will the Listeroid get a face lift?
Snip it....
Uprating of existing product (diesel engines) to meet Stringent exhaust emission norms,
stipulated by Govt., for diesel engines used for Genset
Brief Information :
There was a need to introduce Norms for exhaust emissions - for Diesel Genset, in view of increasing use of Gensets, and in keeping with the Govt. policy to ensure effective controls on Emissions.
IDEMA (Indian Diesel Engines Manufacturer Association) had series of meetings with Central Pollution Control Board (CPCB) to formulate the Norms. KOEL R&Engg played an active role in these interactions. The Norms were formally notified by Govt. in May 2002, to be implemented from July 2003. The Norms were quite stringent, in keeping with the Govt resolve to control the Emissions.
Country : India
Location :
All over India.
Duration :
1 Year.
The Challenge :
KOEL manufactures about 28 models of diesel engines, to suit Genset output from 5 KVA to 250 KVA. All these engines needed review of existing design and necessary up gradation, to meet the stipulated Norms. The time available was short, i.e. only 1 year.
The solution :
Typical engine model were first tested to map the existing Emission level so as to decide the parameters to be addressed.Then, the available knowledge base and design capabilities were fully utilized to decide the course of action.Prototype engines were developed and tested at A.R.A.I., to evaluate the effect on the emissions.
Resultant data base was used to firm up the changes required in the critical engine parts/ systems. Detailed interactions were held with MICO - supplier of fuel injection equipment, which is the main contributor in controlling the emissions.
6 of the engine families, covering 14 engine models, were successfully tested at A.R.A.I. & type approval was received, by end March 03.
KOEL was the first manufacturer to get Type approval for the subject Emission Norms.

Brief Information :
Agricultural Tractors manufactured in India are mostly in the power range of 20-60 HP, in which 30-40 HP range is the most popular.
Of late, requirement for smaller power range 20-30 HP is increasing.
While most of the engines used for this small power range are of 2 & 3 cylinder configuration, one manufacturer has a single cylinder air-cooled engine, rated at 22 HP. This tractor has its own market, mainly due to low initial cost.

The Challenge :
A major Tractor manufacturer approached KOEL, with a requirement to develop a single cylinder watercooled engine, rated at 25 HP/2250 PM, to suit a new Tractor model. While the OEM indicated a definite limit on the 'Cost' of the engine and the development time, the technical requirements included compliance to 'US Tier 1' Emission Norms - with provision for upgrading to 'US Tier 2' Norms - to facilitate export of Tractors to U.S.A. & other advanced countries. Considering the power/torque specifications, other technical requirement and the fast that it would be a cost effective' single cylinder engine - this would be a 'unique' design effort.
The solution :
Details of technical specifications were drawn up and mutually agreed upon to decide start the process.
Apart from addressing the basic design objectives of Low cost, high performance, single cylinder engine, many innovative approaches were followed - like extensive use of 3D modeling and 'concurrent engineering' - by involving major suppliers [castings/pressed parts etc] during the design stage itself.
As a result, the prototype engine was developed within a short span of 8 months - which must be a record for this type of activity wherein a new engine is designed and developed from - Scratch.
The prototype met most of the performance objectives at first go. Optimisation/refinement were done, where necessary, and a pilot batch was manufactured for various tests, including endurance tests on dynamometer as well as tests on Tractor. Problems faced during these tests were quickly de-bugged and a pilot batch of tractors is under extensive field tests at present.
