In this system, the fuel droplets injected from one cylinder side usually tend to wall wet on the piston crown and the other side of the cylinder, which causing an increases of the HC emission. The liquid phase LPG has a lower boiling point and a higher vapor pressure than gasoline. When it is injected with the pressure more than 5MPa, flashing will occur, which speeds up the mixture formation and reduces wall wet. In this paper the mixture formation of direct injection LPG engine at part load and full load were investigated by numerical simulation. The results showed that, compared with gasoline spray using a swirl injector at part load, the LPG spray employing a single-hole injector burst fast once injected, and spray tip penetration was reduced. This resulted that rich mixture was still not guided to the spark plug area, even near the end of compression stroke. Therefore, it is necessary to advance the fuel injection timing of 5∼10°CA for LPG than gasoline at part load using single-hole injector at the same injection pressure. However, at high load, the injection advance could remain the same as that of gasoline.","PeriodicalId":6400,"journal":{"name":"2011 Second International Conference on Mechanic Automation and Control Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81948717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With these software packages, machining force of different processing types could be monitored online and processed offline both in time domain and in frequency domain. The machining force regression models could be established by using single factor analysis method. The three-dimensional milling force testing experiments results show that the flexible testing and analysis system could meet the three-dimensional cutting test of different processes, and the regression models coincide with the cutting force variation law.
