本文介绍了实现汽油发动机极端小型化所需的技术挑战和对策。捷豹路虎（JLR）是一个名为“ULTRABOOST”的合作项目的主要合作伙伴，该项目得到了英国技术战略委员会（TSB）的资助。该项目的目标是开发一种创新的发动机概念，相对于目前生产的运动型多用途车V8发动机，该发动机能够在NEDC驱动循环中减少35%的二氧化碳排放，同时保持关键的车辆属性，如性能和瞬态响应。该项目联合体由捷豹路虎、莲花工程、壳牌燃料、通用电气精密工程、CD-adapco、巴斯大学、利兹大学和伦敦帝国理工学院等8个技术合作伙伴组成。从2010年9月开始，该项目将持续三年，利用合作伙伴在工程、设计、燃烧建模、增压和燃料方面的专业知识和集体技能，开发一种高压增压小型发动机概念。在本文中，所需的技术，使极端水平的发动机小型化和二氧化碳减少的描述，连同附带的模拟数据收集从最初的概念发动机的发展。
This paper provides an introduction to the technical challenges and countermeasures required to enable extreme gasoline engine downsizing. Jaguar Land Rover (JLR) is the lead partner in a collaborative project called ‘ULTRABOOST’ which is supported with funding from the UK Technology Strategy Board (TSB). The project aim is to develop an innovative engine concept capable of a 35% CO 2 tailpipe reduction over the NEDC drive cycle relative to a current production V8 engine in a Sports Utility Vehicle, whilst maintaining key vehicle attributes such as performance and transient response. The project consortium is made up of eight technical partners including Jaguar Land Rover, Lotus Engineering, Shell Fuels, GE Precision Engineering, CD-adapco, University of Bath, University of Leeds and Imperial College London. Starting in September 2010 and running for three years the project will utilise the partners expertise and collective skills in engineering, design, combustion modelling, pressure charging and fuels to develop a highly pressure charged downsized engine concept. In this paper the technology required to enable extreme levels of engine downsizing and CO 2 reductions are described, together with accompanying simulation data collected from the initial concept engine development.
