Diesel engine maker Cummins posted its most profitable fourth quarter results on record, with a rush of sales on engines that did not have to conform to new emissions standards that took effect Jan. 1, reports the Indianapolis Business Journal.
Cummins posted $3.4 billion in sales in the fourth quarter of 2009, up 3 percent from the same period in 2008.
On those revenues, the company saw $270 million in profits, up from $43 million in the same period of 2008, reports the Wall Street Journal.
Cummins said that customers bought the previous generation of engines because they were cheaper and more familiar than new-generation engines that comply with diesel emissions standards by the EPA and the California Air Resources Board.
In November, heavy duty 11- and 13-liter diesel engines from Volvo and Mack passed emissions tests that showed them to be compliant with EPA standards without having to use emissions credits.
