MTU’s Tier 4 Final diesel engines require no after-treatment
MTU’s new Tier 4 Final diesel engines were developed to meet EPA standards without the use of exhaust gas after-treatment in engines above 750 horsepower and no diesel particulate filter at any horsepower. The 2000 and 4000 Series engines are used in mining and construction applications. The Series 2000, a family of 12- and 16-cylinder V-engines with power ratings from 760 to 1,560 horsepower, is said to deliver up to 10 percent better fuel economy and have extended exchange intervals for major components such as injectors and high-pressure pumps. The engines combine four key technologies, including the following:
- Cooled high-pressure exhaust gas recirculation (EGR),
- Regulated two-stage turbocharging,
- Common rail fuel injection, and
- Advanced diesel engine controller (ADEC).
