Development of a new LPG-gasoline injection system for vehicles

使用石油气的车辆（因此：称为丙烷）和汽油由于降低了成本和环境影响以及提高了效率和有效性，最近在世界上的许多地区已经成为了主流。由于这些好处，加拿大交通部鼓励开发传统轻型车辆转换为液化石油气的系统。在这个项目中，迪利亚有限公司将与UOIT的研究团队合作，由I博士领导。Dincer通过NSERC Engage计划进一步开发、改进和优化其系统。由迪利亚有限公司开发的系统主要由喷射轨系统组成，该喷射轨系统由轨内的节流液体LPG冷却，使得燃料作为过冷液体分配到喷射器。该团队将与工业合作伙伴密切合作，通过发明和分析各种系统替代方案来改进喷射器轨道设计，例如：i）将气液分离器纳入轨道，ii）将节流液体熏蒸到进气歧管中，iii）集成 由车辆电池驱动的小型制冷压缩机（低于20W消耗），其将使节流的燃料返回到油箱中并且在切换回汽油之前清空轨道，iv）将热管系统集成到使用LPG作为工作流体的轨道中，使得获得更有效的冷却过程。

Vehicles using LPG (so: called propane) and gasoline have recently become in may parts of the world due to reduced cost and environmental impact and increased efficiency and effectiveness. Due to these benefits, Transport Canada encourages development of conversion system of conventional light duty vehicles to LPG. In this project, Delia Ltd. will work together with UOIT research team led by Dr. I. Dincer to further develop, improve and optimize their system through the NSERC Engage program. The system developed by Delia Ltd consists mainly of an injection rail system which is cooled by throttled liquid LPG inside the rail such that the fuel is distributed as subcooled liquid to the injectors. The team will closely work with the industrial partner to improve the injectors rail design by inventing and analyzing various system alternatives such as: i) including a gas liquid separator into the rail, ii) fumigating the throttled liquid into the intake manifold, iii) integration of a mini-refrigeration compressor driven by vehicle battery (below 20 W consumption) which will return the throttled fuel into the tank and empty the rail prior switching back to gasoline, iv) integration of a heat pipe system into the rail using LPG as working fluid such that a more effective cooling process is obtained.
