The Daewoo K series Heavy Duty Diesel Engine - Development and Performance 2000-05-0072
To meet the more strict regulations against exhaust and noise emissions and the increasingly strong demand for higher power, better fuel economy and higher durability and reliability, Daewoo Heavy Industry Machinery Ltd. has recently developed the K series in-line 6-cylinder, 12.8 liter turbocharged and intercooled diesel engine for heavy duty commercial vehicles.
To achieve these targets, the newly advanced technology, high pressure electronic unit injecter (EUI), 4-valve design and the optimized combustion system, symmetric cylinder block with bed plate and decompression engine brake were adopted and developed. The EUI system is also capable of pilot injection and cylinder balancing.
This engine meets the EURO-3 emission regulations and has power ratings from 257 to 324 kW at 1800 to 2000 rpm, peak flat torque of 1960 Nm at 1000 to 1500 rpm. And very quiet noise characteristic and sufficient durability and reliability were achieved.
This paper describes the development and performance aspects of this engine
