2278 Kohler Engines unveiled its new KDI 3404 engine at bauma 2014 held in Shanghai, China. A 3.4litre (3359cc) unit it is available in two models with a total of four different power outputs. It is aimed at the market's increasing demand for smaller engines with high productivity.

Use of technologies such as high-pressure (2000 bar) Common Rail injection system and electronically controlled EGR valve to recirculate exhaust gases allow more efficient combustion so reducing fuel consumption and giving power levels equivalent to engines  of larger displacement. Thanks to clean combustion no diesel particulate filter (DPF) is required so allowing the engine to be more compact.

KOHLER claims the KDI 3404 uses 10% less fuel than other engines in its category. With best in class power and torque up to 15% better productivity can be achieved by machines it powers over those using the closest competitor.

The standard KDI 3404TCR (turbo common rail) is rated at 55.4kW with peak torque of 375Nm and is compliant to Stage IIIB Tier 4 final.

The other model KDI 3404TCR-SCR has a SCR (selective catalyst reduction) system to reduce NOx gases in the exhaust and complies to Stage IV Tier 4 Final. It is available in three power outputs. The 75kW version has peak torque of 475Nm. There is a 90kW version with 480Nm and the most powerful is 100kW with 500Nm.

    CNH Construction marketing director Jean-Patrick Yekpe has highlighted the money-saving potential of Case Construction Equipment’s new midi-excavators, unveiled at bauma 2013. The Tier 4 Final requirements of the CX75C SR and CX80C have been met, says Yekpe, through the use of cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst system. “When the soot is coming out of the engine as smoke and touches the platinum inside the engine you get an oxidation, and as a consequence of thi

    Komatsu used INTERMAT to take the wraps off two new Dash 7 wheeled loaders, badged WA380-7 and WA500-7. With engine emissions being the main driver, the smaller 18-tonne WA380-7 packs 142kW from its EU Stage IIIb engine to deliver improved efficiency and lower fuel consumption. The machine also gets torque converter lock-up with the function operating in 2nd, 3rd and 4th gears, and gives the loader a 40 km/h forward speed.

The fuel delivery systems for these ultra-low emission diesels can only cope with high quality fuels with very low sulphur content. And tests on the effects of low quality, high sulphur fuels on the low emissions engines have shown corrosion an
