(5) QR Codes a. In order to minimize performance tolerance of injectors at replacing them, QR*1 (Quick Response) codes have been adopted to enhance correction precision. b. Using QR codes has resulted in a substantial increase in the number of fuel injection quantity correction points, and thus the injection quantity control precision has improved. The characteristics of the engine cylinders have been further unified, contributing to improvements in combustion efficiency, reductions in exhaust gas emissions and so on.
