Selective Catalytic Reduction (SCR) for Improved Marine Engine Efficiency

Tub Boat with Vessel

Adhering to today’s strict maritime emission standards doesn’t have to be complicated or expensive. Selective Catalyst Reduction (SCR) helps meet today’s requirements and keep you fully EPA compliant while compensating for its cost through increased fuel efficiency of your Caterpillar machines. It is also simple to use and easy to install. We are proud to offer SCR as an intelligent, cost-saving solution for our customers.    

What Is Selective Catalytic Reduction?

Selective Catalytic Reduction (SCR) is the act of reducing the NOx component in gas. In this process, diesel exhaust fluid is injected into exhaust systems releasing NOx. This fluid then evaporates into ammonia NH3, at which point the exhaust gas and ammonia come in contact with the SCR system and turn the NOx and NH3 into nitrogen and water vapor.

Benefits of Installing SCR

SCR is an effective method of boosting fuel consumption, and the higher a system’s NOx output is, the better the fuel consumption. In most cases, the cost of the diesel exhaust fluid is offset by the lower price of fuel consumption, making it an affordable solution for lowering pollution and adhering to today’s maritime standards. SCR is a preferred method of efficiency by Cat® due to its easy uptime and low cost.

A Proven Solution

Though SCR may sound new, its invention dates back to 1957, and it has proven itself in the maritime field for over two decades. This type of system is common in marine vessels such as tankers, cargo ships, and naval vessels, as well as in power plants and vehicles, such as freight trucks, buses, and locomotives.
