ORGANIZATIONAL PROFILE

Ashok Leyland is a commercial vehicle

manufacturing company based inChennai,India.

It sells about 60,000vehicles and about 7,000engines

annually.

It is first in India's automobile history to win the ISO

-9002certification.

It is the second largest commercial vehicle company

in India in the medium and heavy commercial vehicle

(M&HCV) .

INTRODUCTIONThe engine is the automobile’s source of power .It is a complex device with hundreds of moving parts supported by a number of complicated systems .The modern automobile internal combustion engine converts energy contained in fuel into efficient, inexpensive transportation .

During the short history of the automobile ,hundreds of different engine designs have been invented ,built and tested .Each type of engine layout has certain advantages and drawbacks, but today only a few designs are in wide use.

Ashok Leyland had a collaboration with the Japanese company Hino Motor from whom the technology for the H-series engines was bought. Many indigenous versions of H-series engine were developed with 4 and 6 cylinder and also conforming to BS2 and BS3 emission norms in India.

Future Module

Ashok Leyland, the Hinduja Group flagship, today launched the NEPTUNE

engine ushering in a new era in engine technology. Designed and developed in-

house from a clean sheet, the NEPTUNE family of engines has been globally

benchmarked for greater fuel efficiency, lower maintenance, longer life, greater

reliability and superior NVH (Noise, Vibration and Harshness) characteristics.

NEPTUNE engine will be available in BS-III and BS-IV versions and is also

package protected for BS-V and BS-VI. The highly modular sub-system design

ensures maximum vehicle uptime and better NVH characteristics while the CRS

with electronic-governance ensures high fuel efficiency, easy serviceability,

lower life cycle cost and reliability.

Conclusion

Working in an industry like ASHOK LEYLAND has been an enriching

experience .Here in the training I came to know about all the process being

followed are health monitoring when applied to prime movers such as the diesel

engine have long been appreciated: reduced unscheduled down-time and increased

availability.

When it comes to the development of environmentally friendly technologies,

Ashok Leyland has developed Hythane engines.

Aside from the full expansion planned for the company, Ashok Leyland is also

paying close attention to the environment. In fact, they are one of the companies

showing the strongest commitment to environmental protection, utilizing eco-

friendly processes in their various plants. Even as they thrust into different

directions, Ashok Leyland maintains an R&D group that aims to uncover ways to

make their vehicles more fuel efficient and reduce emissions.
