Turbochargers significantly increase efficiency in the vehicle and improve exhaust gas quality. Our highly innovative wastegate systems and turbine wheels contribute significantly to the implementation of modern turbochargers. High-temperature resistant as well as hot-gas-corrosion resistant materials and alloys offer the best prerequisites for implementation in our precise manufacturing and assembly processes.
An exhaust gas turbocharger basically consists of a compressor and a turbine. The exhaust gases that escape after combustion drive the turbine. The connection via a shaft simultaneously drives the compressor wheel, which compresses the intake air and thus delivers a larger mass of air into the combustion chambers of the cylinders. The effects are higher engine power, higher torque, reduced fuel consumption and lower emission values than with comparable naturally aspirated engines.
For optimal functioning of the exhaust gas turbocharger, boost pressure control is necessary. An unregulated turbocharger has a very narrow operating range for good efficiency. Without a wastegate system, there may be a loss of intake pressure. Uniform boost pressure and thus the absence of "turbo lag" is made possible by a so-called wastegate system. This allows the boost pressure to be flexibly adjusted in any situation. It is important that the flap plate is 100% tight - it needs an exact degree of mobility for optimal functioning, which we at BLANK can realise perfectly!
