Perkins at Bauma 2010

  • 15-Mar-2010 10:54 EDT

Perkins' 1206E-E70TTA 7-L engine is one of many Tier 4 Interim/Stage IIIB compliant engines on display at Bauma. It is a six-cylinder unit capable of producing 225 kW (300 hp).

Perkins' message as it prepares to showcase its full range of Tier 4 Interim/Stage IIIB compliant engines is that the engines are "designed to not only offer specific power outputs but also a choice of engine configurations and options that provide machinery OEMs with the ability to 'design-in' the engine with a minimum of re-engineering."

It considers the 1200 Series a key part of its cleaner, compact diesel engines. The models have a power span that ranges from 60 to 225 kW (80 to 300 hp). On show at Bauma representing the 1200 Series will be the 1206E-E70TTA, offering 225 kW (300 hp) at 2200 rpm, and the 1204E-E44TTA with 129 kW (175 hp) at 2200 rpm.

The 7-L 1206E-E70TTA is a six-cylinder unit that has a 21% increase in power over Perkins’ current 6.6-L offering, giving OEMs (who may have previously chosen a larger engine) the choice of the same power from a smaller engine package.

It is fitted with two turbochargers that are mounted in series. The smaller first-stage turbo accelerates quickly for improved response and torque at low speeds. The larger second-stage turbo has the high airflow required to provide improved power density.

A 6.6-L shorter stroke version, the 1206E-E66TA, was aimed for applications that require a lot of torque at low engine speed, says Perkins.

Both 1206 models use a diesel oxidation catalyst and diesel particulate filter to ensure forthcoming particulate emissions compliance.

Lower down the scale, the 1204 is replacing the 1104. The 4.4-L, four-cylinder model is available in two versions, with the 1204E-E44TA producing 110 kW (148 hp); it uses a single turbocharger and is intercooled. The twin-turbo, after-cooled 1204E-E44TTA is rated at 130 kW (174 hp) and employs a two-stage turbocharger for extra power density and faster response.

All 1200 Series engines for Tier 4 Interim/Stage IIIB use Perkins’ NOx Reduction System, with field trials indicating significant improvements in fuel consumption and sound quality over existing Tier 3 models. Prototype six- and four-cylinder engines are currently being validated in a number of machines, with over 50,000 hours on the test bed and 4000 hours in machines already logged.

Bauma will also be the first showing for Perkins’ new 854 Series compact, four-cylinder 3.4-L engine. Offering more power and torque from a smaller package, customers will now be able to move seamlessly through the power bands as the 854E produces from 45 to 86 kW (60 to 115 hp).

The 854E range benefits from a common-rail fuel-injection system, smart wastegated turbocharger, and an aftercooler, all regulated by full authority electronic controls.

Starting in 2011, the engine, which develops a peak torque of 420 N·m (310 lb·ft), will be available in the 2200 to 2500 rpm range.

Making extensive use of “voice of the customer” research, Perkins designed the range with a strong emphasis on power density, fuel consumption, and performance, giving OEMs choice and support if downsizing is desired.

Perkins’ 400 Series, which is already Tier 4 Interim/Stage IIIB compliant, will also be on show at Bauma. The engine range, which has a power span from 8.2 to 49.3 kW (10.9 to 66.9 hp), currently is the power source for more than 200 different applications.
