Bauma stop press

With around 3000 exhibitors and some 530000 m² of exhibition space, there is no construction equipment exhibition in the world quite like Bauma. It is likely to attract more than 400000 visitors, and being the biggest show in the industry's calendar, it will be the launch pad for several-thousand new machines.

Engines

Following the introduction of Stage IIIA engine emissions laws for engines in the 19 to 37 and 75 to 130 kW powerbands, visitors can expect to see a plethora of new machines on show featuring these engines. One of the largest stands is sure to be Cummins’. The company says that along with the latest range of Tier 3/Stage IIIA compliant engines will be its A Series units, which it claims are the first production Tier 4/Stage IIIB compliant engines to appear on the market. Cummins says its Tier 4 technology is built on the identical industrial engine range that was launched for Tier 2, in 2002.

The A Series engines range from 23 to 35 kW, with a configuration that provides manufacturers with long-term platform stability. The 3-cylinder A1700 and four cylinder A2000 and A2300 units are ideal for compact construction equipment. According to the company, they provide high power density and a compact envelope, ideal for skid steers, mini excavators, rollers and all other forms of compact equipment.

In a slightly different vein, Deutz will be showing a hybrid engine-powered construction vehicle produced in conjunction with Weyhausen. Specific information on the machine is not yet available, however, it will definitely be worth a look.

In addition to this, Deutz will be showing its 2010 series of engines, with outputs up to 75 kW. Compliant with Tier 3/Stage IIIA, the basic concept of these engines will be used to take Deutz into Tier 4/Stage IIIB and beyond.

The engines are four cylinder turbocharged units with a displacement of 3.5 litres, available with charge air-cooling as an option, depending on the application. Testing on these new units will be carried out over 2007, with production expected to begin in the second half of 2008.

Also on the stand will be the latest versions of the proven 2011 series compact engines, which are now available with water-cooling. The primary reasons for this development, says Deutz, was customer requests for higher outputs with unchanged installation space, as well as the need to meet the Tier III/Stage IIIA emission limits.

Kubota's new engines in its 07 Series will have centre stage on its stand. The 3 litre V3007-DI-T and 3.3 litre V3307-DIT offer 50 to 55 kW of power and feature direct injection and turbo charging. According to Kubota, boThengines are very compact with sizes comparable to a conventional 2.2 litre engine. The company has achieved the small size through side mounting of the power take of, rather than from the fly-wheel. BoThengines feature centre injection and are ready for use of common rail and electronic control to meet Tier 4/Stage IIIB.

Italy's Lombardini will also be launching the first three models in a new range of 15LD silenced 1-cylinder air cooled diesel engines. The new 225S, 350S and 440S will offer between 3 and 8.8 kW of power, but will generate up to 4 d(B)A less noise than a conventional engine of the same size.

The injection systems and internal cylinders on the silenced engines has been redesigned to achieve the lower noise levels without changing the external size of the 15LD engines. Although silencing is not mandatory for this size of engine, Lombardini believes that use of the engines will help OEMs to achieve overall noise reduction targets for completed machines. The full range is expected to be available in 2008.

Perkins will be celebrating its 75th Anniversary at Bauma, and will have its latest ranges of engine on show, with particular emphasis being placed on the 10 model 400 Series range of compact units. The 402D-05 (10.2 kW) and the 404D-05 (38 kW) will be on the stand.

Three new units have been added to the range in the shape of the 30 kW turbocharged 403D-15T, the naturally aspirated 403D-17, and the 49.2 kW 404D-22TA (turbocharged and aftercooled).

Also on the stand will be representative models from the company's 1100 Series products. Based around a 1.1 litre platform, the engines are available in forms that suit the needs of OEMs for units that are suitable for non-regulated markets through to Tier 3/Stage IIIA compliant units.

Sweden's Scania will be debuting three new engines at this year's Bauma exhibition. The largest will be the 16 litre V8 DC16 EMS, which produces 420 kW of power and has been designed to produce lower levels of emissions to meet the requirements of Stage IIIA.

Scania will also be presenting the 9 litre 5-cylinder DC9 EMS (243 kW) and the 12 litre 6-cylinder DC12 EMS (331 kW) engines, both of which are also Tier 4/Stage IIIB compliant. Lower emissions on all three engines have been achieved through the use of a revised combustion chamber, a refined injector angle and an improved camshaft.

Yanmar will also be displaying the latest versions of its engines, which have been designed to meet the next phase of Tier 3/Stage IIIA that will come into force on 1 January 2008. The company has used electronic governing on its engines in the 37 to 63 kW powerband to meet these new emissions regulations, and according to the company, this has enabled it to keep the power output and external size of the engines the same.
