Euro 6 buses

Whilst only 4% of UK roadside emissions come from buses, we still want to make every change we can to help make a difference. Over the last four years our miles per gallon (MPG) has improved by 7.5% with fuel consumption dropping by 1 million litres. Co2 emissions combined have improved by 16% at 29,000 tonnes and we want to make this even better. We also continue to invest extensively in a low carbon fleet. Euro 6 micro hybrid buses have a lot to offer in terms of improving air quality and reducing nitrogen oxide (NOx).

NOx is produced from the reaction of nitrogen and oxygen gases in the air during combustion, especially at high temperatures. In areas of high motor vehicle traffic, such as in large cities, the amount of nitrogen oxides emitted into the atmosphere as air pollution can be significant.

What are the benefits of a Euro 6 bus?

A Euro 6 bus delivers a 67% reduction in NOx. The Euro 6 reduced emissions are achieved by a SCRT system (selective catalyst regeneration trap) and a DPF (diesel particulate filter) both designed to reduce NOx levels. 

How do these buses work?

Euro 6 micro hybrids have a compressor, steering pump and alternator that are all electrically operated whereas other older buses are driven from a drive system from the engine increasing the load and effecting fuel efficiency. Our micro hybrid vehicles also have regenerative braking, that store energy reducing the need for the engine to generate it.

How does a Euro 6 bus benefit people and the environment? 

The NOx limit for Euro 5 diesel vehicles is 180mg/km. This has been significantly reduced to just 80mg/km for Euro 6 diesel vehicles. This in turn reduces the amount of NOx released into the air. We know that NOx has a negative on health so the less of it in the environment the better and especially for people with respiratory issues.

We operate 55 Street Decker buses in Brighton & Hove and 27 Street Lites in Crawley.
