“…The mathematical model of the functioning of the system is a system of ordinary differential equations. The system of linear differential equations with constant coefficients was solved analytically for a limited number of elements at a fixed value of failure and recovery rates [43]. To establish the nodes limiting the reliability of the fuel system, using statistical data, dependencies of the failure probabilities for their main elements were obtained.…”

One of the main trends in the development of modern engine building is the use of biodiesel fuel, which can lead to a decrease in the reliability of engines that are not adapted to it. However, at present there is no general method for determining the reliability of fuel systems of internal combustion engines. In this paper, a reliability model of engine fuel systems when operating on biofuel has been developed. Comprehensive indicators for assessing the reliability of diesel engine fuel systems are the coefficient of readiness and technical use. The availability factor of the fuel system when operating on biodiesel fuel without the replacement of structural materials was 0.66, while with the replacement it was 0.71, and the coefficient of technical utilization without replacement of materials was 0.36, and with the replacement of 0.4. Recommendations are given to improve the reliability of the engine fuel system components. The resulting model allows for complex comparisons of the effectiveness of various ways to improve the reliability of engines running on biodiesel fuel.

“…Almost all the biodiesel properties are within the standards, but the CPO biodiesel and AIO biodiesel have low cetane number, which makes the engine problematic to start and noisy. 74,75 Density and kinematic viscosity are important properties in the fuel injection and engine performance respectively. Higher viscosity can customize a larger droplet which leads to improper fuel atomization.…”

Rapid industrialization and population expansion increased the demand for petroleum-based fuels, resulting in price hike and creates serious environmental issues. Biodiesel, a clean, renewable and long-lasting alternative and for large scale production needs readily available and sustainable feedstocks. Edible and non-edible plants are abundant in Southern India, particularly Ceiba penandra (CP), Mahua longifolia (ML), and Azadirachta indica (AI), which were employed in this study in combination. An efficient heterogeneous nano-catalyst CaO-TiO2 was synthesized and employed in the transesterification process due to its recoverability and insensitivity to FFA. The catalyst was subjected to characterize by FTIR, XRD and SEM with EDX mapping. Response surface approach is engaged in this study for cost-effective production. More than 95% biodiesel yield was achieved for Ceiba penandra oil (CPO), Mahua longifolia oil (MLO), Azadirachta indica oil (AIO) and their mixture (MIO) by optimization of significant reaction parameters and the best combination was obtained as methanol oil ratio (0.32, 0.46, 0.34 and 0.42 v/v), catalyst usage (5, 6.5, 6 and 4 wt.%), mixing intensity (750, 840, 700 and 540 rpm) and duration (80, 105, 85 and 85 min) respectively with constant temperature of 70°C. Fatty acid profile was characterized by chromatograph also established the properties by ASTM and EN guidelines to confirm its compatibility in the IC engine.

“…The HFRR technique was applied through not only steel-steel contact but also steel-ceramic and steel-diamond contacts. Xiao et al 29 investigated the tribological performance of diesel, soybean biodiesel, and their blends of 0, 20, 40, 60 80, and 100 vol%. The test was conducted on the samples coated with ceramic (ZrO2) and diamond materials, also.…”

This research aimed to investigate the lubricity and wear properties of ultra-low sulfur diesel fuel (ULSD) blended with biodiesel and doped with biodiesel-based organic compounds. In this work, neat n-dodecane served as a surrogate for ultra-low sulfur diesel fuel (ULSD), Fischer Tropsch, and renewable diesel fuels. Additionally, some pure hydrocarbons were also investigated for unsaturation and carbon chain length. Tribological characterization was conducted on quenched and tempered AISI 4140 steel, substituting diesel fuel pump material, and using the ball-on-disc technique. The wear rates of biodiesel samples were about 2–4 times less than the vegetable oils. Esterification improves the lubricity of vegetable oils. The wear rate of biodiesel is about 5–7 times greater than that of fossil base commercial Eurodiesel fuel. Using biodiesel as an additive had a significant effect on the lubricity of pure n-dodecane, adding 2 wt% biodiesel resulted in 5–7 times wear rate reduction that equivalent to the lubricity level of commercial Eurodiesel fuel. Wear rates of pure hydrocarbons showed that wear is reduced with increasing chain length and unsaturation.
