Contribution to the environment
The use of an HJS SMF
® sintered metal filter makes it possible for diesel soot emissions to be almost entirely eliminated and for vehicles and machinery alike to be operated cleanly and efficiently. This, in turn, enables diesel engines to be deployed as a drive or power source in a wide range of applications, and helps reduce fuel consumption and CO2 emissions. Comparison of a diesel engine and a petrol engine with comparable power output reveals that a diesel emits a good 10 per cent less CO2 than a petrol engine.
What´s more, the use of steel makes it possible to implement a filter design that has a particularly high capacity for storing non-combustible particles, such as engine-oil ash or metal particles. These particles – like the soot, too – are trapped by the porous metal filter. Over the years, considerable amounts of these inert particles collect in the filter. Compared with conventional ceramic filters, the SMF® is capable of storing many times the amount of these elements (commonly called "ash") without the exhaust backpressure noticeably increasing. This fact, and the lower backpressure in particular, means the SMF® also facilitates further fuel savings.
The SMF® enables particulate matter emissions to be reduced right down to the limit of detection: particulate reduction rates of up to 99% are achieved, which means the exhaust gases actually emitted are as good as particulate-free. Thanks to this exceptionally high reduction rate, widespread deployment of the filter could make a substantial contribution to reducing global levels of particulate pollution. High concentrations of particulate matter in the air are contributing significantly to the problem of climate change, because ultra-fine particles can trigger cloud formation and reflect the sun´s rays. Reducing the levels of particulate matter pollution, therefore, is an important part of the efforts to protect the climate.
What´s more, since the SMF® is made entirely of high-grade steels, it can be recycled at the end of a vehicle´s or engine´s life without requiring any form of complex separation of materials, because it is 100% recyclable.
