Efficient, clean combustion
Visiolution Sensors for Optical Combustion Analysis
Optical spark plug sensors for combustion measurement tasks
AVL’s Visiolution technology helps you understand the whole process in detail. We provide the right solutions so that performance regarding fuel consumption, mixture formation, exhaust emissions and engine power is all improved.
Strict emission targets have led the automotive industry to more complex combustion technologies. As a result, robust and thorough analytical methods have become essential. Our optical spark plugs offer an excellent solution for the detailed analysis of combustion phenomena in addition to the classical pressure sensors. Moreover, our optical sensors can be used on board a test vehicle.
AVL’s Optical Measuring Methods
At AVL three variations of visio spark plug sensors are available. The mounting size of M10x1 enables the use of optical sensors even if there is not enough space. There are five optical elements that provide the functionality of VisioKnock measurements with 15 cones of view. In addition, an optical element provides a view of the piston to identify the diffusion of the flame radiation.
The most popular design is the M12x1.25, it covers a broad range of crank angle-based flame measurement applications. For an advanced combustion analysis, a visio spark plug the size of M14x1.25 is also available. Each solution is available from 8 to up to 80 channel versions and customized solutions can be built upon request.
