“…At high engine loads, more fuel was injected which resulted in longer diffusion combustion during, while there was poorer fuel-air mixing than with premixed combustion, leading to higher local equivalence ratio; therefore, a higher absolute mass of particles was produced at higher engine loads [49], for both the fuel sets and at both the timing conditions ( Figure 21 and Figure 22).…”

Better understanding of combustion and formation of exhaust gas pollutants of fuels is needed in order to meet stringent regulation standards of a diesel engine. The cetane number is one of the mostcited indicators of diesel fuel quality. This paper presents experimental studies with a wide range of fuels to investigate the effect of cetane number on combustion and exhaust emissions (CO, NO x , PM, particle number size distribution). The fuel ignitability was controlled in two different ways: naturally, by using seven fuels (Dearomatised Hydrotreated Stream, Hydrotreated Non-Dearomatised Stream, Soy Methyl Ester, Rapeseed Methyl Ester, Heavy Paraffinic Stream, C10-C14 Paraffins, and C14-C17 Paraffins) with different cetane numbers, and through the use of an ignition improver blended into a single base fuel (Hydrotreated Non-Dearomatised Stream (NDH)) to change the ignition chemistry of the fuel while keeping physical properties unchanged. The tests were performed in naturally-aspirated single-cylinder DI diesel engine at 1200 rpm and 600 bar injection pressure at 4 bar and 6 bar IMEP. The engine tests were carried out at constant fuel injection timing and constant start of combustion timing. A strong positive correlation was found between ignition delay and CO emissions. The effect of physical and chemical properties of the fuel on NO x and particulate emissions became more dominant at higher load. Overall the results showed that changes in the fuel physical properties and molecular structure, in particular, the incorporation of oxygen, impacted on combustion and emissions through various routes in addition to the effects of ignition delay only.

The fuel quantity and injection pressure are two essential factors to optimize the injection strategy. In this paper, we focus on the investigation for the ignition and combustion characteristics of wall-impinged kerosene (RP-3) fuel spray at different injection quantities and pressures. Experiments are conducted in a constant volume combustion vessel to simulate the Diesel engine condition, adopting a single-hole nozzle with 0.22 mm. The flame images are captured using a high-speed camera, and then the behaviors of ignition and combustion are processed and analyzed. The main emphasis is placed on the variation laws of the ignition position distance, the ignition delay time, the combustion duration, the flame area, spatially integrated natural luminosity and time integrated natural luminosity.

“…Table 3 presents the properties of biodiesel from waste cooking oil, renewable diesel, ULSD, diesel + and Jet A. Jet A is characterized by lower viscosity, distillation temperature range, and cetane number as regards ULSD fuel; the lower density, viscosity, and surface tension cause its better atomization when compared to diesel fuel [20].…”

“…Llamas et al [19] used Jet A1 that was blended with bio kerosene; their investigations concluded that biodiesel could be used to partially substitute fossil jet fuels. Chen et al [20] investigated the emissions from a single cylinder diesel engine that was fueled with kerosene. Such a fuel improved the indicated thermal efficiency and reduced the soot emissions; nitrogen oxide emissions did not have a relevant variation.…”

Impact on Combustion and Emissions of Jet Fuel as Additive in Diesel Engine Fueled with Blends of Petrol Diesel, Renewable Diesel and Waste Cooking Oil Biodiesel

This study is devoted to investigating the potential use of Jet A in blend along with biodiesel from waste cooking oil, petrol diesel, and renewable diesel. Biodiesel use allows for reducing carbon monoxide (CO), unburned hydrocarbons (HC), and soot due to the oxygen contained in the fuel. The drawbacks in its use are related to the low volatility and high viscosity of vegetable oil that cause difficulties in fuel atomization and in its mixing with air. Moreover, an increased amount of NOx emission was observed. The aim of the experimentation is to evaluate the ability of Jet A of enhancing the combustion process and pollutant emissions of a diesel engine, thus overcoming the difficulties in biodiesel usage (high viscosity, poor cold weather performance, compatibility with diesel engine equipment) and then increasing the renewable fuel percentage in the fuel. Testing was carried out on a small displacement common rail diesel engine. Hardware and ECU setting were not modified in order to let the engine be ready to operate with different and exchangeable fuels. The effect on pollutant emissions of a variation of the amount of Jet A and biodiesel in the fuel is investigated, while accounting for the engine speed value.
