Engine

The engine complies with the following off-road emission regulations (market dependent): • Europe (EU) step 2 (all versions) • USA (EPA) step 2 (NAFTA version only) • California (CARB) step 2 (NAFTA version only) D10B ACE2 (A25D) and D10B AAE2 (A30D) are NAFTA versions, D10B ADE2 (A25D) and D10B ABE2 (A30D) are only certified for the EU. Advantages • Low emissions for lower environmental impact. • Meets EU, EPA and CARB step 2 emission regulations (market dependent). • Power and torque curves designed for hauler applications. Technical features • Wet replaceable cylinder liners for more efficient heat dissipation and simple overhauls. • Hydraulic fan with variable control provides con- stant operating temperatures in all operating con- ditions. • Water trap and fuel filter effectively remove impuri- ties from the fuel.

Volvo haulers are equip p ed with well-known, widely accepted and efficient Volvo diesel engines, built to meet the demands of an articulated hauler.

High-performance, fuel efficient Volvo engine The A25D and A30D are equiped with the Volvo D10B engine, a six-cylinder in-line, direct-injected, turbo- charged low-emission diesel engine with intercooler. Fuel injection is electronically controlled for low emissions and high performance. The engine is characterized by a high torque rise which provides high torque at low engine speeds. This means that the engine responds quickly when accelerating from low engine speed. This is required for confronting the high total rolling resistance when operating on soft ground, on steep grades and in rough terrain. The engines have high power to maintain a high average speed throughout the entire work cycle. Combined with a low maximum engine speed, this gives high productivity, low fuel consumption, less noise, reduced wear and longer service life due to the fact that the main part of all operation takes place at relatively low engine speeds.
