Caterpillar has been able to offer Cat C280 medium speed diesel engines that meet Tier 4 and Tier III requirements

It is reported that the Cat C280 medium-speed diesel engine has 8 cylinders, 12 cylinders and 16 cylinders. As the (regular and diesel-electric) mainframe covers a power range of 2,300-5,060 kW, the aircraft can also be used as an auxiliary generator set. Compared to earlier diesel engines, the machine has numerous advantages, which can reduce emissions, consume less fuel and have lower lifetime ownership and operating costs.

In listing the key advantages, Carter explained: "Although the Cat C280 medium speed diesel engine is well known for its long uptime, reliability and durability, we are a priority for these diesel engines that meet Tier 4 requirements. The lowest life cycle possession and operating costs are achieved. We have achieved success by increasing the efficiency of the engine. Unlike previous engines that meet various Tier requirements, the choice of catalytic reduction (SCR) system will reduce the amount of Nitrogen oxide production, our engine that meets Tier 4 requirements can operate at optimum fuel efficiency. Due to the choice of catalytic reduction system, any concern about the cost of diesel exhaust fluid (DEF) is greatly improved. offset."

It is vital to maintain maximum operational safety at all times. Unlike some other nitrogen oxide reduction technologies, the operation of the Cat C280 medium speed diesel engine does not interrupt operation even when a selective catalytic reduction (SCR) system fails or exhausts diesel exhaust fluid. There is no effect on the operation of the engine. ”

It is understood that from January 2014, the EPA Tier 4 standard applies to all newly constructed US flagged vessels, and all newly constructed vessels are required to meet the IMO NOx emission control from January 2016. District (NECA) requirements.
