Finning Meets Tier 4 Regulations with Latest 3500 Range Engine

With the Environmental Protection Agency’s (EPA) Tier 4 standards coming into full effect in 2017, Finning UK & Ireland (Finning) has launched the Cat 3516E – a new diesel engine from the acclaimed Cat 3500 series, to meet customer demand for low fuel emissions.

On 1 January 2017, all new engines with a maximum power of 1000bkW must meet the EPA’s Tier 4 emission regulations, which demand an 80 per cent reduction in oxides of nitrogen (NOx) and particulate matter. By October 2017, all new engines with a maximum power of 600bkW and above must be compliant too. In response to this, Finning – the UK’s sole provider of Cat engines – is now supplying the innovative 3516E engine.

The engine utilises selective catalytic reduction (SCR) technology to help reduce harmful NOx emissions. A urea-based solution is injected into the system’s exhaust air stream, with the energy contained in the hot exhaust gas causing the NOx to evaporate as ammonia. A catalytic converter then breaks down the ammonia and exhaust gas into harmless nitrogen gas and water vapour.

The 3516E also offers improved total cost of ownership, with a lower total fuel consumption cost when compared with similar models on the market. In SCR technology, engine-out NOx and fuel consumption are inversely proportional, meaning the greater the engine-out NOx then the lower the volume of fuel consumed.

Available in power ranges from 2501 to 3386 BHP (1865 to 2525bkW), and speed ranges from 1600 to 1800 RPM, the 3516E delivers an assured reduction in fuel emissions while delivering the highly engineered performance and efficiency that the 3500 series is known for.

Eric Hyder, Strategic Account Manager at Finning, said:

“With 35 years of experience serving the marine sector and more than 26,000 installations, the 3500 series is one of the most well-established and proven engine technologies available on the market. The launch of the 3516E engine includes Cat’s intelligent SCR innovation to meet the EPA’s Tier 4 emissions standards, ensuring marine operators can be sure they are cutting fuel emissions in line with regulations, without compromising on performance and reliability.

 “We have every confidence in the efficiencies SCR technology can help realise. With over 84 million hours running time to date for products on the market utilising this innovation, the benefits of this technology are tested and proven.”

The engine is available with a comprehensive operations and maintenance (O&M) contract from Finning. Supported by a dedicated team of expert marine technicians, which are on-call 24/7, 365 days a year, Finning’s O&M packages can include remote monitoring, emergency call-outs, scheduled services and repairs, an in-house fluid analysis service and genuine spare parts.
