Volvo Construction Equipment D8M

The register lists here 8 versions with 191 to 393 kW rated output at 1,800 to 2,240 rpm, all inline six-cylinder engines with 110 to 144 mm bore and 135 to 165 mm stroke. Seven of the eight engines use a variable-geometry turbocharger, one a simple wastegate unit. The emission stage splits into Tier 4 (Final or Phase-in) with 5 and Interim Tier 4 with 3 versions, the power category is uniformly 130 to 560 kW. Maximum torque runs from 1,246 to 2,570 Nm at 1,000 to 1,450 rpm, model years from 2012 to 2026; the range is certified for both the other states and California.

Engines of these ranges power Volvo CE's heavy construction-machinery programme – wheel loaders, articulated haulers and large excavators used in quarrying, open-pit mining and earthmoving. Unlike the road engines of Volvo's sister brands, D engines in construction machinery are tuned for high pulling power at low speeds and long service life under varying load.

On a used purchase, the condition of the variable-geometry turbocharger and its actuation, the tightness of the exhaust gas recirculation and charge-air cooler, oil consumption, and operating hours relative to the machine's history all matter. Parts and service run through the Volvo CE dealer network.
