The Optare Olympus (introduced in 2006 as the East Lancs Olympus) is a double-decker bus built by Optare, East Lancs and Darwen. It could be built as a body available on Alexander Dennis Enviro400, Volvo B9TL or Scania N230UD/N270UD chassis with the 2-axle and 3-axle variants. It is the double-decker equivalent of the Optare Esteem. Some 3-axle ...
The Volvo B7TL is a low-floor double-decker bus chassis which was launched in 1999 and replaced the 2-axle version of the Volvo Olympian (its 3-axle version was replaced by the Volvo Super Olympian). It was built as the British bus operators seemed hesitant to purchase the B7L double decker with a long rear overhang (although some have since ...
Volvo nearly completed the phaseout in 2016 [47] with only two variants of the five-cylinder diesel remaining in production for the 60-series models. In December 2014, Volvo introduced the first hybrid variant of a VEA engine with the launch of the XC90 T8. It uses an electric rear axle drive (ERAD) for both electric propulsion and AWD ...
Later systems collect oil in a sump, from where it can be collected and pumped around the engine again, usually after rudimentary filtering. This system has long been the norm for larger internal combustion engines. A pumped oil system can use higher oil pressures and so makes the use of hydrostatic bearings easier. These gave a greater load ...
[clarification needed] A large double-curvature upper deck windscreen (either single-piece or two-piece) is one of the most distinctive features. Originally a tall, wrap-around lower deck windscreen was fitted, but some batches were fitted with a double-curvature windscreen, with either a straight or an arched top.
Aside from the increased bore size, the engine is identical to the B21. Volvo used a slightly different mold for the turbo engines to cast a boss for the turbo oil return line. Because a turbocharged engine has a higher operating temperature they used sodium filled exhaust valves and a thermostat controlled oil cooler (air/oil model).
The Volvo B5LH (initially known as the Volvo B5L Hybrid, also known as the Volvo BRLH) is a low-floor hybrid electric bus chassis for both single-decker buses and double-decker buses manufactured by Volvo since 2008. It is the basis for Volvo's integral 7700 Hybrid full low floor city bus and its successor, the 7900 Hybrid from 2011. In 2008 ...
