TGX / TGS Euro 5 Engines

Euro 5 emission engines are now available from MAN for all Heavy Duty TGX & TGS trucks. The TGX & TGS range feature the MAN D20 and D26 engines with outputs from 360hp to 540hp (265kW to 397kW). All of the engines use the tried and tested SCR technology with exhaust gas treatment to meet the new Euro 5 / ADR 80/03 emission regulations. Electronically controlled Common Rail fuel injection ensures consistent and efficient injection of finely atomised fuel at pressures of up to 1800 bar at precisely defined intervals within the compression and power strokes. The fuel mixture burns cleanly and efficiently, and the engine runs quieter. The MAN high pressure fuel system is gear driven from the crankshaft which allows very high fuel pressures to be generated even on idle. Maximum fuel pressure is generated at very low revs resulting in a more responsive engine. The MAN Common Rail system design includes an accumulator which holds reserves of fuel for the rail and allows multiple injections per stroke giving improved torque delivery. Optimal engine tuning for Euro 5 emissions allows the engine to produce very low particulates during combustion.

The nitrogen oxides (NOx) produced mix with a urea solution (AdBlue速) which is injected into the exhaust gases. This gaseous mixture passes through the catalyst exhaust system where the ammonia and nitrogen oxides react to form water vapour and nitrogen gas. The Euro 5 catalyst exhaust muffler is the same dimensions as the Euro 4 version, so no compromise on the available chassis space.

Up to 480Hp, the engines are also available in the more stringent EEV (Enhanced Environmentally-friendly Vehicle) emission standard which reduces the particulate emissions by a further 33% compared with Euro 5. This allows operators the choice to demonstrate a higher degree of environmental responsibility.
