In August of 2006 I was approached by Somender Singh and an associate of his on the possibility of testing his groove concept and provide an analysis on what he effects of the groove were. Several ways of testing were discussed and we came to the conclusion that a custom built dynamometer would provide the best way to perform a controlled test of the grooves and the effect. In late September 2006 I was commissioned to begin work on the dyno and so my consulting company, AutoTronixs, LLC, began work. Over the next 10 months the dyno, electronic sensing, control and data acquisition software, testing and data collection was designed and built. The following 2 months was used to collect and analyze data from a whole battery of tests. Two reports were produced on the findings on what effect the grooves were shown to have.
The first tests were normal engine running tests. These simulated normal types of engine loading as one would see going down the road, anywhere from in town to high speed on the highway. All engine running parameters, dynamometer loading and tailpipe emissions parameters were collected by the computerized data acquisition system. Exhaust gases readings were obtained by a 5 gas exhaust analyzer. Right click to download.
The second tests were ionization current tests. These tests utilized the method of applying a voltage across the spark plug after the coil spark to induce a minute current during the combustion process. This current could then be used as a combustion signature and give insight into many of the characteristics of the combustion process. This report shows graphically the combustion signatures as a function of crank angle. Right click to download.
