The company is proposing to research, design & develop a fuel tolerant compact lightweightfuel efficient 5kw auxiliary power unit incorporating a novel wankel rotary engine (WRE)with direct injection stratified charge technology. The current state of art involves 3 cylinderdiesel or petrol engines which are bulky & weigh on average around 160kg. The major focusfor this project is auxiliary power units for heavy duty tractor, trailer trucks, portablelightweight military applications, range extenders for city cars & some industrial &commercial uses. The auxiliary power unit offers long haul truck drivers amenities like airconditioning/heating during rest breaks without the need to idle the truck engine. Thetechnology could eliminate 11 million tons of carbon dioxide emissions each year from idlingthe truck engine as well as providing a fuel saving of $6,000 on average per each truck. WithUS legislation now in force that stops the idling of engines for more than 30 minutes and withAPU’s only having 5% penetration the market potential is considerable. In the electric vehicle(EV) market, lack of range causes range anxiety for users which is the fear that the vehicle hasinsufficient battery charge & thus range to reach its destination. With EV’s the range of thevehicle is generally between 50km-100km. The proposed APU technology has the potential todouble this range & therefore significantly reduce range anxiety for the UK and globally.Environmental benefits based on very low adoption rates for the technology are stillsignificant 67,000 tonnes of CO2. The technical problem facing the market is the availabilityof a reliable compact lightweight fuel tolerant, fuel efficient engine to power theAPU/generator set capable of optimal power output of 5kw at a competitive price. Theproposed concept has both the potential to meet both the technical and cost objectivesnecessary for successful exploitation.

该公司计划研究、设计和开发一种耐燃油的紧凑型轻型燃油效率5千瓦辅助动力装置，该装置将采用新型汪克尔转子发动机（WRE）和直喷分层充电技术。目前的技术水平涉及3缸柴油或汽油发动机，这些发动机体积庞大，平均重量约为160公斤。该项目的主要重点是重型牵引车、拖车、便携式轻型军事应用、城市汽车增程器以及一些工业和商业用途的辅助动力装置。辅助动力装置为长途卡车司机提供便利设施，如在休息期间提供空调/供暖，而无需闲置卡车发动机。这项技术每年可以减少1100万吨卡车发动机空转时的二氧化碳排放量，并为每辆卡车平均节省6,000美元的燃料。随着美国立法现在生效，停止空转发动机超过30分钟，与APU的只有5%的渗透率，市场潜力是相当大的。在电动汽车（EV）市场中，里程不足会导致用户的里程焦虑，这是担心车辆没有足够的电池电量，从而无法到达目的地。电动汽车的续航里程一般在50公里到100公里之间。拟议中的APU技术有可能将这一范围扩大一倍，从而大大减少英国和全球的范围焦虑。基于该技术非常低的采用率的环境效益仍然显着67，000吨二氧化碳。市场面临的技术问题是可靠的紧凑型轻质耐燃油、燃油效率高的发动机的可用性，以具有竞争力的价格为APU/发电机组提供最佳功率输出5 kw。所提出的概念既有潜力，以满足技术和成本目标所需的成功开发。
