Hastighets- och positionsinterface för motorer
The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries. The aim is todevelop a standardized hardware interface for the measurement of speed and position for combustionengines. This thesis reviews the two most common sensors for measuring the speed and position ofcombustion engines. The thesis also analyzes and compares two existing hardware interfaces. Bycombining the advantages of the existing interfaces with new ideas, a new enhanced interface will bedeveloped.
