In this paper, physical property parameters including density, viscosity and surface tension of different contents of diesel-gasoline blend fuel were measured and analyzed. The experiments were performed on the dieselgasoline blend fuels with 4 different volume fractions of diesel (20%, 40%, 60% and 80%) at temperature from 5 • C to 65 • C. The influence of temperature and diesel content on the blends' properties was summarized based on experimental data, formulas about the material parameters were established, and the accuracy of these formulas was verified. Besides, saturated vapor pressure, freezing point and flash point of the blend fuel have also been measured and analyzed, and a database of the material parameters of the blends was also established. Key words: internal combustion engine, diesel-gasoline blend fuel, physical property CLC number: TK 407.9Document code: A IntroductionWith the widespread use of internal combustion engine (ICE), environment has been damaged due to the harmful substances released from the ICE, which are also harmful to human health, therefore it is of great significance to develop more efficient and lower emission combustion mode for ICE. Compared with traditional ICE combustion mode, homogenous charge compression ignition (HCCI) is considered as a promising technology, which can simultaneous reduce the harmful emissions and improve combustion efficiency of ICE. The biggest challenge of HCCI combustion is how to control the starting point of ignition and the burning rate effectively when the operating condition of engine changes. Besides, the narrow operation range of HCCI engine is also a big problem [1] .Due to high viscosity and low volatility of diesel fuels, one of the primary problems for the HCCI diesel engine is how to form a homogeneous mixture quickly [2] , for gasoline engine, however, because of the high octane number and auto-ignition temperature of gasoline fuels, it is not so easy for the mixture to achieve its auto-ignition temperature in different operating conditions [3] . Bessonette et al. [4] investigated different kinds of fuels used in HCCI engine, the results showed that in order to make the engine operate in HCCI mode with better performance, the physical properties of the ideal HCCI fuel should between diesel-and gasoline-like fuels.Turner et al. [5] first employed the Diesel-Gasoline blend fuel in a gasoline direction injection (GDI) engine, and the blend fuel was named after "dieseline". Han et al. [6] carried out series researches on the combustion and emissions characteristics of a single-cylinder diesel engine using the Diesel-Gasoline Blend Fuel, their research results showed that by employing a proper ratio of diesel to gasoline, the operation range of HCCI engine could be greatly broadened, meanwhile a lower emission level could be achieved. A reduced gas-phase chemical mechanism of "dieseline" was developed by Kokjohn et al. [7] , then the mechanism was coupled with the KIVA code to establish the "dieseline" HCCI mode, based on this mode, lots of...

“…As the proportion of gasoline increases, soot emission is significantly reduced due to the increase in the proportion of premixed combustion [3]. Xu et al [4] named gasoline-diesel blend fuel as dieseline, and found that dieseline increased the combustion stability and extended the operating range of HCCI. Han et al [5,6] studied the premixed LTC fueled with gasoline-diesel blends.…”

“…As a result, the operation range of high-efficiency and clean LTC with diesel is still limited within low and medium loads. [5] is demonstrated as a promising fuel for simultaneous reduction of NO and soot emissions at a lower EGR level, owing to the improved premixture by the better volatility and lower CN. The relevant works have been conducted extensively during the past decade [5,6], but it is challenging to further increase the engine load.…”

The relevant works have been conducted extensively during the past decade [5,6], but it is challenging to further increase the engine load. Based on the deep insight into fuel properties of LTC, Johansson et al proposed to inject gasoline directly into cylinder by common-rail system, which is referred to as partially premixed combustion (PPC) concept [7].…”

The present study focuses on the experimental investigation on the effect of fuel injection strategies on LTC with gasoline on a single-cylinder CI engine. Firstly, the engine performance and emissions have been explored by sweeping SOI1 and split percentage for the load of 0.9 MPa IMEP at an engine speed of 1500 rpm. Then, the double-injection strategy has been tested for load expansion compared with single-injection. The results indicate that, with the fixed CA50, the peak HRR is reduced by advancing SOI1 and increasing split percentage gradually. Higher indicated thermal efficiency, as well as lower MPRR and COV, can be achieved simultaneously with later SOI1 and higher split percentage. As split percentage increases, NO emission decreases but soot emission increases. CO and THC emissions are increased by earlier SOI1, resulting in a slight decrease in combustion efficiency. Compared with single-injection, the double-injection strategy enables successful expansion of high-efficiency and clean combustion region, with increasing soot, CO, and THC emissions at high loads and slightly declining combustion efficiency and indicated thermal efficiency, however. MPRR and soot emission are considered to be the predominant constraints to the load expansion of gasoline LTC, and they are related to their trade-off relationship. Recently, the fuel properties of LTC have gained great scientific concerns, mainly because fuel properties control the time scales of both chemical kinetics and fuel-air mixing. Thus, it is suggested that a less reactive fuel is preferred for combustion control at high engine loads. In the former studies, mixture of gasoline and diesel termed as dieseline
