DENSO Develops a New low Cost Fuel Injection System for Small Motorcycles

Kariya, Japan, May 29, 2014 - (JCN Newswire) - Global automotive supplier DENSO Corporation 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.

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.

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. Specific compensation technologies include a temperature estimation control that integrates a thermistor into an electronic control unit and a fuel metering control to determine acceleration/deceleration using an intake air pipe pressure sensor.

DIET-FI is currently manufactured by Gongcheng DENSO (Chongqing) Co., Ltd., a group company that manufactures motorcycle components and supplied to Wuyang-Honda Motors (Guangzhou) Co., Ltd.

DENSO is committed to developing environmental technologies that help improve fuel economy and reduce emissions, as well as develop products suited to the regional's needs.

Overview of FI systems (electronic fuel injection systems)

FI systems for motorcycles consist of sensors, actuators, and ECUs to ensure high-precision control of the air-fuel ratio. The optimal fuel injection volume is calculated based on the air volume, engine condition, etc., which are detected by sensors. The fuel from the fuel pump is fed into the engine by injectors with high precision.

The widespread application of FI systems to small motorcycles will require smaller components, simpler systems, fewer components, and lower cost compared with four-wheelers and large motorcycles.

Predictive analytics tools monitor, report, and troubleshoot in order to make proactive decisions about the health, performance, and utilization of storage. Most enterprises combine cloud and on-premise storage, resulting in blended environments of physical, virtual, cloud, and other platforms, which justifies more sophisticated storage analytics.

They have a question on their mind like “How is my application doing” but no id...

In IT, we sometimes coin terms for things before we know exactly what they are and how they’ll be used. The resulting terms may capture a common set of aspirations and goals – as “cloud” did broadly for on-demand, self-service, and flexible computing. But such a term can also lump together diverse and even competing practices, technologies, and priorities to the point where important distinctions are glossed over and lost.
All clouds are not equal. To succeed in a DevOps context, organizations should plan to develop/deploy apps across a choice of on-premise and public clouds simultaneously depending on the business needs. This is where the concept of the Lean Cloud comes in - resting on the idea that you often need to relocate your app modules over their life cycles for both innovation and operational efficiency in the cloud.
