We have developed a new engine roughness tester which is capable of monitoring the spark plug voltage and crankshaft speed fluctuation as well as detecting the misfire of the SI internal combustion engine. In order to detect misfire, the newly developed “spark plug voltage analysis method” is combined with the conventional “crankshaft speed fluctuation method”. It is capable of logging ordinary data, determining the waveform for a detection / misfire

We have developed injection molding technologies consist of a new high-strength long-glass fiber reinforced polypropylene (PPLGF). They are key technologies of new modular design for substantial reductions of weight and cost, offering integrated functionality. The strength of injection molded parts are three times stronger than that of the conventional material. This technology makes it possible to replace parts from steel stamping and press molded glass-mat reinforced polypropylene. The front end and door modules of Mazda 6 employ the module carriers using this material, resulting in dramatic weight and cost savings.
