Volvo – for a first-class fleet
Volvo’s B8R range will meet any need in intercity and commuter operations, the company states. It’s highly versatile through a range of variants, yet firmly focused on reducing operating costs.
The Volvo D8C330 engine is an in-line six-cylinder 7.7-litre 330hp engine, equipped with an overhead camshaft, four valves per cylinder and common-rail injection system. The engine meets the European Union’s exhaust emission standards according to Euro 5.
The eight-litre Volvo engine is very fuel-efficient with high capacity, the company says. As a result, it is among other things suitable for bulk-goods, regional long haul distribution and light construction where both performance and fuel economy are crucial factors.
The engine boasts a sturdy, dependable design. Featuring an overhead camshaft, four valves per cylinder and precisely controlled common-rail injection and waste-gated turbocharger. Driveability is excellent thanks to the broad torque range.
The engine timing mechanism is at the rear of the engine, which leads to less vibration and permits a rear-mounted power take-off. The engine electronic control unit (EECU) controls various functions of the engine, and contributes to a low fuel consumption and low exhaust emissions. The system also offers advanced scope for diagnostics and fault-tracing.
Another key part of Volvo’s driveline set-ups is the I-Shift 12-speed manual gearbox with an automatic gear-changing system. The Volvo I-Shift is designed for tourist, intercity, regional and route operations, where it provides high driving and ride comfort and excellent fuel economy.
Volvo I-Shift is a fast-responding gear-changing system with minimum interruption in torque delivery during changes and a wide ratio span, a combination that offers impressive resources for high average speeds, it’s stated. The system consists of a non-synchromesh manual gearbox with an electronically regulated pneumatic gear-changing system and an automatic clutch. The gear selector is integrated with the driver’s seat and gearchanges are fully automated.
Starting ratio is selected automatically in response to road gradient and gross vehicle weight. Volvo I-Shift is available with a choice of programme packages and various functions. Among them is a facility for choosing between fully automatic gearchanges and manual selection, and a performance mode with a kickdown function that utilises the engine’s capacity to the maximum.
The transmission is a compact, lightweight unit. It is divided into a base unit and a range-change unit. The base unit, range section and clutch housing are made of aluminium, which contributes to the low weight. The transmission is factory-prepared for installation with or without a compact retarder (VR3250).
Long oil-change intervals mean low operating costs and less environmental effect. When special oils are used, oil and filter changes take place after a maximum of 400,000km or every third year.
The engine boasts a sturdy, dependable design.
