Tier 4 diesels to 225 kW

Perkins will display its complete line-up of engines up to 225 kW that comply with the Tier 4 Final/EU Stage IV laws that start coming into force from 2014.

Perkins said the new 90 kW 854F-E34TA would spearhead the range on show – an engine which features SCR technology as well as a diesel oxidation catalyst (DOC) module, but without the requirement for a DPF.

The manufacturer said heat rejection remained similar to its predecessor Tier 4 Interim model, meaning no major changes to the size of the cooling pack, helping to maintain the engine’s compact dimensions.

Alongside the 854F-E34TA, models on display include the single turbo 1206F-E70TA, which for OEMs wanting lots of torque at low speed, offers up to 15 1 kW at 2,200 rpm with maximum torque of 870 Nm at 1,400 rpm.

In developing the 1200 Series, Perkins also sought to minimise the impact of the aftertreatment required to meet Stage IV/Tier 4 Final requirements, and while a DPF is required for these models, it is packaged together with the DOC canister and the SCR system into one integrated module, which can be positioned remotely in a machine chassis or directly on top of the engine.

The lightweight yet compact dimensioned aftertreatment module minimises space claim in the engine bay and incorporates a number of features to ease installation. These include flexible inlet and outlet options, pre-installed electronics and diesel exhaust fluid (DEF) lines hook ups – all of which are said to contribute to minimal work for the OEM.
