Making construction machinery cleaner and more efficient

Bosch is offering solutions that can help reduce emissions for construction machinery in the UAE and cut operating costs 

The company is taking a two-pronged approach ? continuing to refine established diesel systems while pioneering electrification and fuel-cell technology. 

Andreas Bodemer, V-P of Middle East and Africa Region at Bosch Automotive Aftermarket commented, ?In the lead up to infrastructure projects such as Dubai Expo 2020, a considerable amount of building material will arrive into the country. Bosch?s solutions will help not just reduce operating costs for transport operators, but also reduce emissions from engines. Our innovations directly support initiatives underway in the UAE and thereby also the nation?s emission reduction goals.? 

Hybridisation and fuel cells: the future of the off-highway powertrain

? E-drive for engines in the off-highway segment: Bosch offers various components for electrical powertrains and also links them into whole systems. Add in specially designed software, and the result is a complete powertrain system for off-highway applications.

? Hybrid excavators with energy recovery systems: Hybrids are set to become tomorrow?s heavyweights as Bosch brings the electrical powertrain into the off-highway arena. One example of this is robust systems that recover the energy that is released when rotational movement is put a brake on. Hybrid excavators with energy recovery systems could become a common sight on the construction sites of the future. The new technology also allows automakers to downsize and downspeed engines, which can save up to 40 per cent in fuel. At the same time, the new hybrid technology helps automakers comply with future emissions limits: lower fuel consumption reduces CO2 emissions.

? Fuel-cell control unit: For construction machinery with zero local emissions, Bosch Engineering offers a key technology for fuel-cell powertrains ? the fuel-cell control unit (FCCU). This component is the nerve centre for off-highway fuel-cell applications. It is based on technology proven in large-scale automotive production.

Lower operating costs: diesel solutions for construction machinery

? Systems competence: Apart from injection technology, this includes engine management, sensor technology, and exhaust-gas treatment. The electronic engine control unit is the central control unit for the injection system in large engines. Accurate and up-to-date data from the exhaust system are the basis for all functions, from mixture formation to exhaust-gas treatment. Special sensors have been developed for this purpose.

? Connectivity: ability to predict service visits reduces down times and costs

? Preventive diagnostics: To prevent such down times, Bosch is developing preventive diagnostics. For example, a connectivity control unit could gather operating data from a diesel injector over its entire service life and monitor its operation online from the cloud.

According to the company, standards such as Final Tier 4 (US) or Stage V (Europe) will soon result in even tighter emissions requirements for construction and agricultural machinery.
