Cummins has been associated with the Indian subcontinent for five decades. The stage was set way back in 1962, when a partnership between Kirloskar and Cummins crystallized into a 100-acre manufacturing campus in Pune. Within a span of three years from commencing operations, the business venture started to generate profits. Thereon, the partnership continued to flourish, till up till 1997, when the Kirloskar’s sold their ownership; resulting in Cummins Inc. increasing its stake to 51% and the rest being traded on the Bombay Stock Exchange. This led to the formation of Cummins India Limited, a consolidated subsidiary of Cummins Inc.

Today, Cummins India Limited has grown to become the country’s leading manufacturer of diesel and natural gas engines. It is only one of the eight legal entities (including four joint ventures) of the Cummins Group in India, signifying Cummins’ increasing presence in the country. Comprising of four business units - Industrial Engine, Power Generation, Distribution, and Automotive, Cummins India Limited is also the largest entity of the Cummins Group in India.

• The Industrial Engine Business caters to the industrial sector with its broad spectrum of diesel engines ranging from 18 HP to 3500 HP. The range is designed to power varied market segments such as Construction, Mining, Compressor, Marine, Rail, Agriculture, Pumps, Oil & Gas, Power Generation and Defense.
• The Power Generation Business addresses standby and prime power needs through the design and manufacture of pre-integrated generator sets, transfer switches, paralleling equipment and controls.
• The Automotive Business integrates Cummins’ diesel and natural gas engines with related technologies such as filtration, exhaust, turbo, fuel and coolant systems and lube oil to serve the commercial vehicle segment in India.
• The fourth business, Distribution operates under the brand name ‘Cummins Sales and Service India’. Acquired in 1967, with the objective of providing products, packages, services and solutions for uptime of Cummins equipments, it has since been engaged in the business of sale of engines, and providing after-market support to customers in India, Nepal and Bhutan.
