Ceramic Injection Molding Process from Thuringia Actively Contributes to Global CO2 Reduction
QSIL Ingenieurkeramik GmbH, based in Frankenblick, Thuringia/DE, delivered the 11 millionth ceramic sliding shoe for axial piston pumps. An impressive number, even though the pump component itself is only about the size of a fingernail, more than ten million vehicles have been equipped with it. They would probably reach more than once around the earth if they were lined up along the equator. It sounds a bit like a super jam, but in purely technical terms it’s a super thing that helps diesel engine manufacturers reduce emissions of climate-damaging exhaust gases.
The sliding shoe developed by QSIL, which has quickly established itself as a standard component for controllable water pumps in 4-cylinder diesel engines worldwide, runs against a stainless steel swashplate during engine operation. The pressure thus generated serves as a hydraulic actuator for controlling the control technology. This enables the engine’s warm-up phase to be significantly shortened and, in the course of thermal management, the coolant flow can be controlled as required.
Shortening the warm-up phase makes a significant contribution to reducing climate-damaging exhaust gases during cold starts. In normal operation, the water pump can be controlled as required. This reduces the power consumption of the pump and thus CO₂ emissions.
The special feature of the sliding shoe from QSIL is the material from which it is made. Silicon nitride (Si₃N₄) ceramic, also known as non-oxide ceramic. Compared to conventional DLC-coated steel parts (DLC = Diamond-Like Carbon), this high-performance ceramic material offers better performance at a lower price. The decisive advantage of ceramic sliding blocks compared to sliding blocks made of coated steel is the significantly improved – i.e. lower – friction. This reduces CO2 emissions from vehicles and also increases driving comfort thanks to the shorter warm-up phase.
