STUDY ON BIODIESEL HEAT TRANSFER THROUGH SELF-TEMPERATURE LIMIT INJECTOR DURING VEHICLE COLD START

ABSTRACT
A type of Self-Temperature Limit-Injector (STL- injector) is proposed to reduce the biodiesel consumption and emission in vehicle cold start process. The STL-injector is capable of fast raising fuel temperature, which helps improve the quality of diesel spray and its combustion efficiency. A STL-injector model is established with consideration of electro-mechanic coupling and fluid-structure interaction. A transient simulation is conducted using dynamic grid technology. The results show that STL-injector can effectively raise biodiesel temperature to 350K from 300K in 32 seconds. That is to say, adding STL-injector to existing biodiesel combustion system is an environment-friendly solution due to improving atomization and spray quality quickly.
