Detroit Diesel Series 149
The Detroit Diesel 149 is a series of diesel engines by Detroit Diesel which first came out in the early 1960s.
The first configuration was a naturally aspirated 12V149 rated at about 600 hp (450 kW) soon followed by a naturally aspirated 16V149 rated at about 1,000 hp (750 kW). As manufacturers in the marine, construction, mining, and many other industries required more power output, Detroit added turbocharging and intercooling to the engine. Over a period of time, Detroit Diesel continued to further the design of the engine. They finally brought the engine up to 137.5 hp (102.5 kW) per cylinder and 406 ft·lbf (550 N·m) torque per cylinder; needless to say, this is a considerable amount of power coming from 149 cubic inches (2,440 cc) per cylinder. Much of this increase in power could be contributed to DDEC III (the third generation of Detroit Diesel Electronic Controls) electronics, thermal barrier (ceramic) coating of piston domes & fire deck, by-pass valve controlled blowers and Separate Circuit Charge Cooling (SCCC) system.

Famous quotes containing the word series:
“Through a series of gradual power losses, the modern parent is in danger of losing sight of her own child, as well as her own vision and style. It’s a very big price to pay emotionally. Too bad it’s often accompanied by an equally huge price financially.”
—Sonia Taitz (20th century)
