VW NGD 370 engine The
Volkswagen Group NGD 370
turbodiesel engine premiers new attributes for the heavy trucks sector. The high "flat"
torque at low engine speeds is improved by a variable geometry
turbo-compressor: the Multi Turbo System - MTS. Its
cylinder head features
four valves per cylinder,
displaces (9.4 litres), and generates at 2,000 rpm. It also comes with the Dual Power Brake – DPB. All are supplied by
ZF Sachs, and range in diameter from to . The engine output is routed through a variety of
transmissions. One option is the
ZF 16S 1685 TD 16-speed manual synchromesh transmission. This latest
ZF box is lighter than existing models, due to its all-
aluminium alloy casings. It has a
torque handling capacity of . The 6x2 variants use a
Meritor MS 23-185 tractive rear axle, and this has a maximum capacity of 60 tons. It includes a series differential locking system when used on the VW 25.370 tractor unit. The 6x2 variants also have the facility for partial or total lifting of the third axle, which helps achieve better traction, particularly on slopes. This Extra Traction Device (ETD) ensures part of the third axle load, during partial lifting, is transferred to the tractive axle. 6x4 variants utilise Meritor MD/MR 25-168 tractive rear axles, and are located via
Randon S.A. rear
suspension (
bogie type rigid shafts in tandem). ==Specifications==
