Caterpillar introduces medium speed machines that meet Tier4 and TierIII requirements
Caterpillar (ship hangar location) has been able to offer Cat C280 medium speed diesel engines (purchased from the US Environmental Protection Agency (EPA) Tier 4 and International Maritime Organization (IMO) Tier III requirements.
According to Caterpillar, the Cat C280 medium-speed diesel engine is available in 8-cylinder, 12-cylinder and 16-cylinder models. It is available as a (regular and diesel-electric) mainframe (purchased from the product library) with a power range of 2,300-5,060 kW. It can also be used as an auxiliary generator (product library supply) group. 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 ownership and operating costs are achieved. We have achieved success by increasing the efficiency of the engine (purchasing supply). Unlike previous engines that meet various Tier requirements, because of the choice of catalytic reduction (SCR) system In place, a large amount of nitrogen oxides will be reduced, and our engine that meets Tier 4 requirements can operate at optimum fuel efficiency. Any concerns about the cost of diesel exhaust fluid (DEF) due to the selective catalytic reduction system are used. The improved fuel efficiency is largely 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. â€
It is reported that since January 2014, the EPA Tier 4 standard applies to all newly constructed US flagged vessels, and all newly constructed vessels will need to meet the IMO NOx emission control zone from January 2016. (NECA) requirements.
