Cummins India reported a 20.6% rise in third-quarter profit on Wednesday, as demand for its engines and power generator sets recovered following a hit from new emissions norms. The Indian unit of U.S. truck engine maker Cummins posted a consolidated profit after tax of 4.99 billion rupees ($60.2 million) for the quarter ended Dec. 31 from 4.14 billion rupees a year earlier. Sales rose 16.8% to 25.10 billion rupees on the back of stable demand for its newly launched and more expensive power generator sets.
