“…Many other researchers investigated this field. A complete review for green fuels as alternative fuels for diesel engines is presented by Othman (Othman et al, 2017) while the review of performance, combustion and emission characteristics of biodiesel fuelled diesel engines is presented by Tamilselvan (Tamilselvan et al, 2017). By implementing the characteristics and properties of alternative fuels into a program code, along with some model modifications, numerical simulations of diesel engines running with fuel blends or pure alternative fuels can be obtained with the presented quasi-dimensional model.…”

The paper presents two components of developed quasi-dimensional numerical model: spray package penetration and gas inflow from the zone without combustion into the spray packages. Correction of spray package penetration along the fuel spray radial axis is presented and described numerically. Numerical model simulation is validated in several measured operating points of direct injection diesel engine, after which the simulation results are presented. According to numerical model settings, each fuel spray was divided into packages (control volumes). In the same time interval, the shortest penetration was obtained for spray packages located at the fuel spray edge. Before reaching the break-up time spray package penetration was linear and after reaching the break-up time, package penetration had a curved form. Later injected spray packages quickly reached and surpassed earlier injected spray packages because earlier injected spray packages hit "gas wall" in the engine cylinder and they were "braked" with surrounding gas in comparison to packages injected later. Gas inflow from the zone without combustion into the spray packages is the most intensive for spray packages positioned at the fuel spray edge. The simulation shows that the inflow mass from the zone without combustion increases for spray packages injected later.

“…Because of the high air-fuel ratio and heterogeneous combustion of air-fuel mixture in the diesel cylinder, NO x and PM levels are relatively higher than those in the gasoline engine exhaust [1][2][3][4][5]. Selective catalyst reduction (SCR) systems have been extensively investigated for the removal of NO x [6], where an aqueous urea solution is injected into the upstream tailpipe of the SCR catalyst to be decomposed into NH 3 and then restored on a catalyst surface for reaction with NO x in the exhaust gas, generating nitrogen (N 2 ) and water vapor as the main products.…”

This paper aims at investigating the fault diagnosis of the selective catalyst reduction (SCR) outlet temperature sensors and fault-tolerant control methods of the SCR system, and three typical faults of downstream temperature sensors were modeled and analyzed to present influences of different faults on the SCR system performances (such as nitrogen oxides (NO x ) emission and conversion efficiency, NH 3 slip, urea dosage and ammonia coverage estimation). A temperature model was established to estimate the SCR outlet temperature, and diagnostics were developed based on the differences between model estimates and sensor measurements. Once a downstream temperature sensor fault was detected, the fault-tolerant control will be enabled, and the output of the sensor may be substituted with the estimates of the model. Thus, SCR performances shall be maintained within the acceptable ranges. Moreover, a 0-D SCR model was also established to validate the capability of diagnostics and fault-tolerant control strategy over the European transient cycle (ETC).

“…New or used vegetable oil and animal fat are sources of biodiesel. Biodiesel production methods are classified as direct use and blending, microemulsification, pyrolysis, and transesterification, among these, transesterification is an attractive and widely accepted technique [1]. Biodiesel is generated by chemical reaction from vegetable oil, animal fats and waste frying oils with an alcohol such as methyl alcohol and a catalyst, generally a strong base like sodium hydroxide or potassium hydroxide.…”

Biodiesel production from waste frying oil as a fuel can help the recycling and contributing to the economy. Transesterification reaction is preferred, it is not because the most common technique, it is one of the most efficient ways for the biodiesel production. The transesterification parameters of waste frying oil were applied as 6:1 Methanol to oil molar ratio with NaOH catalyst 0.4 g (w/w), 57°C reaction temperature, and 60 minutes reaction time and transesterification yield 88.5%. In this study, the effect of biodiesel blends with the organicbased manganese additive on performance and exhaust emissions of a single-cylinder, fourstroke, direct injected diesel engine with air cooling system at 2200 1/min fixed engine speed and with four different engine loads was experimentally investigated. The engine loads are (BMEP, 0.12 MPa, 0.24 MPa, 0.36 MPa and 0.48 MPa), and at the beginning of the tests, the engine was warmed with No. 2 diesel fuel. The oil and inlet air temperatures were kept at 85 ±2 °C and 25 ±1 °C, respectively. The testing fuels used in the experiments were composed of waste frying oil biodiesel blended with the No. 2 diesel fuel volumetrically with the ratio of 20, 40 and 60, respectively. The results obtained from the experimental study were compared with No. 2 diesel fuel. The effects of blends on CO, THC, NOx and smoke were investigated by emission tests. Additionally, brake specific fuel consumption of test fuels was examined. By virtue of the environmental effects, biodiesel production from waste frying oil has been become significant.
