Volvo's first Euro 4 on trial in London
THE FIRST Euro 4 Volvo for operation in the UK enters trial service this month with Go-Ahead in London. It is a B9TL – the replacement for the current B7TL – with Wrightbus body.
The bus has a Volvo D9B 9.36-litre engine and a ZF Ecolife 6-speed automatic gearbox, which will be unique to the B9TL.
The engine features SCR (Selective Catalytic Reduction) exhaust after-treatment, which works by injecting AdBlue into the exhaust gases. The AdBlue is stored in a 40-litre tank. Volvo says that as well as reducing pollution the new engine offers better performance, lower fuel consumption, and extended service intervals.
Steve Dewhurst, commercial director of Volvo Bus, says: "London is a key market for the Volvo B9TL, as it was for its predecessors - the B7TL and the Olympian - hence the capital’s selection for UK field tests. Judging by the successful Euro 4 trials of our products in Europe, coupled with Volvo’s proven double-deck pedigree, we are in a position of confidence to be discussing orders with a number of key operators around the country."
Dewhurst adds that the B9TL meets both Euro 4 and Euro 5 emissions standards.
