Additive follows SAFED training and ‘GreenRoad’ on-bus telematics system. 

East Yorkshire Motor Services (EYMS) has adopted Energenics’ fuel-saving additive Envirox across the whole of its operations in East and North Yorkshire following a successful trial at Driffield depot.

This is the latest in a series of measures to reduce fuel consumption in its fleet of 300 buses and coaches which consume about six million litres of diesel each year.

Previous measures include a specialised driver training programme for Safe And Fuel Efficient Driving (SAFED) and the introduction of the ‘GreenRoad’ on-bus telematics system, which features a ‘traffic light’ signal in the cab to indicate to the driver how efficiently the bus is being driven.

The diesel fuel storage tank in each of the company’s depots will now be fitted with dosing equipment, which injects Envirox into the diesel fuel flow on delivery from the road tanker.

The 12-month trial started in July 2010 on a mixed fleet of buses and studied the effect of Envirox and the GreenRoad system both separately and in combination.

The results showed each measure provided a worthwhile improvement in fuel consumption on their own and the combination provided an extra benefit.

EYMS chairman Peter Shipp said: “In the present very difficult financial climate, we need to save money wherever we can and fuel is now such a big proportion of our total costs that this is a high priority area for us. Based on the successful trial we are confident Envirox will deliver a considerable fuel saving. However, this will only make a moderate dent in the extra £500,000 more we shall pay for diesel per year after the 20% reduction in BSOG from April 1.”

Envirox is based on an oxidation catalyst widely used in catalytic converters. The material has been re-engineered using nanotechnology to allow it to be delivered as a diesel fuel treatment. This ensures a cleaner burn within the combustion chamber, resulting in improved fuel efficiency and lower emissions. It also facilitates the removal of carbon deposits from the engine and diesel particulate filters.

Mike Attfield, CEO of Energenics Europe, said: “EYMS take a professional and thoughtful approach in pursuing their strategy for saving fuel. The Driffield trial was well managed and was a first in confirming our belief that Envirox adds further savings to those achieved by telematics-based driver information systems. As a regular user of EYMS service 76 to Withernsea, it pleases me to know that Envirox will also help to improve the air quality in the area.”
