A system of benefits

For the Stage IV and Tier 4 Final legislation, Volvo Penta has chosen to work with Selective Catalytic Reduction (SCR) technology paired with a light Exhaust Gas Recirculation (EGR) system. Apart from lowered emissions, this solution provides benefits such as easier installations, lowered maintenance costs, increased fuel efficiency and increased productivity.

Easy and reliable

Emissions are reduced by means of SCR technology. There are many ways to build an SCR system. At Volvo Penta, we’ve kept our SCR as simple and reliable as possible. While others have chosen more complex installations and C-EGR (cooled exhaust gas recirculation) systems – we use only two parts: SCR and light EGR. The benefits are obvious: the fewer components used, the easier the installation will be and the less risk of part failure or system malfunction.

The Truth about EPA Tier 4 Final for Diesel Gensets

The Environmental Protection Agency (EPA) has established scaled standards to restrict emissions of nitrogen oxides (NOx), carbon monoxide (CO), particulate matter (PM) and non-methane hydrocarbons (NMHC). These standards have been implemented in stages over the last 24 years. The latest and most restrictive EPA standard for stationary diesel engines today is Tier 4 Final, which reduces emissions up to 99 percent compared to previous tiers.

Towards sustainability

Environmental care is one of Volvo Penta’s core values and we work actively to develop resource efficient products with low environmental impact. However, sustainability means more than just emission levels. It is just as much about fuel economy, ease of installations and the total cost of ownership – all the parts that lower the environmental impact of your chosen power solution. Field testing to ensure durability, reliability and suitability for the application in the environment where they are to be used, is conducted and the latest advances in technology are employed to ensure that the engines meet emission legislation.
