Worldwide, the need for mobility is increasing and thus the demand for automobiles. These are good news for automobile manufacturers, but not with a view to global climate change. Automobiles still contribute to a high degree of human-induced CO2 emissions. Therefore the European Union restricted the amount of CO2 emissions. The average CO2 emission limit for newly registered motor vehicles is 130 g per kilometre effective as at 1 January 2012 and there is an emission target of 95 g per kilometre for 2020. If, from 1 January 2012, the manufacturers of passenger cars exceed the calculated targets, the European Commission will impose an excess emissions premium. In other countries, such as United States, similar systems are in place.
Customers of the SHW Group are being challenged to develop sustainable concepts to be able to meet future CO2 standards or fuel consumption rules. At the same time, they have to react to diminishing oil supplies. To achieve these global targets, the automobile industry is focusing on ways to reduce fuel consumption, especially by increasing the efficiency of combustion engines and reducing vehicle weight, but also by developing and marketing alternative drive concepts.
The SHW Group has early started in the research and development of CO2 reducing products. In the future, too, the Company wants to be a leading technology partner to its customers and provide them with products that contribute to a reduction of fuel consumption and consequently CO2 emissions.
By producing variable pumps the SHW Group provides potential for efficiency improvements. For example, the SHW Group develops and produces variable and map controlled oil pumps which are characterized by the fact that they operate only to the extent that they are actually needed. If not needed, it is disconnected from the engine, which reduces fuel consumption. Particularly with respect to hybrid vehicles, electric pumps can contribute to fuel savings because they consume less electricity and, therefore, reduce the ultimate demand on the combustion engine.
The SHW Group manufactures several components for variable camshaft phasers, such as chain wheels, rotors, stators and signal transmitter discs as well as camshaft phasers. Camshaft phasers reduce consumption and lead to improve the engine’s performance range and torque curve. This contributes essentially towards reducing CO2 emissions. By the production of components made from aluminium weight is reduced, which contributes to the reduction of fuel consumption.The SHW Group plans to optimize its products for the reduction of CO2 emissions and to develop new pumps and engine components. Opportunities arise, for example, in alternative drive concepts.
