Denso develops new low cost fuel injection system for small motorcycles
Denso has developed a new electronic fuel injection system for small motorcycles called DIET-FI . DIET-FI is the world’s first fuel injection system that doesn’t use a throttle position sensor or engine temperature sensor. Instead, it uses newly developed control technologies that ensure the same fuel economy and environmental performance as conventional fuel injection systems, thus cutting costs. Denso’s DIET-FI has five fewer components than conventional systems. Through extensive research, Denso developed control technologies that were able to eliminate the throttle position sensor, intake air temperature sensor, engine temperature sensor and ISC idle speed control step motor.
Usually, fuel injection systems are only used in motorcycles, but in recent years there has been a growing need to apply these systems to smaller motorized bikes up to the size of 150cc that are used in emerging markets, like China. Denso researched this trend and identified a low-cost fuel injection system that delivers similar fuel economy and environmental performance as conventional systems but with fewer components.
