Karanja Oil

Global warming due to engine exhaust pollution and rapid depletion of petroleum oil reserves, has given us the opportunity to find bio fuels as alternative to diesel fuel. Biodiesel is an oxygenated, sulphur free, non-toxic, biogradable and renewable fuel. Karanja biodiesel is prepared using Karanja oil and methanol by the process of transesterification. In the present study, a military 720 kW turbo charged, compression ignition diesel injection (CIDI) engine was fuelled with diesel and Karanja oil methyl ester (KOME) biodiesel respectively. These were subjected to 100 hours long term endurance tests. The performances of fuels were evaluated in terms of brake horse power (kW), torque, heat release rates and specific fuel consumption. The emission of carbon monoxide (CO), unburnt hydrocarbon (UHC), oxides of nitrogen NOx and smoke opacity with both fuels were also compared. Lubricating oil samples, drawn from the engine after 100 hours long term endurance tests, were subjected to elemental analysis. Atomic absorption spectroscopy (AAS) was done for quantification of various metal debris concentrations. Use of Karanja oil methyl ester (KOME) biodiesel in a turbo charged CIDI engine was found compatible with engine performance along with lower emission characteristics (UHC 70%, CO 85.6%), and exhaust noise 11.9% but 13.7% higher NOx emissions. Engine metals wear were found 32% lower for a KOME biodiesel operated engine.

Improved Performance

This study concentrates on enhancing the performance of the gasoline engine through nano-lubrication. The effect of Graphene nano-platelets (GNP) as lubricant additives in SAE 15W40 oil on the fuel energy consumption and piston ring wear is investigated. GNP-filled lubricating oil boosted the brake strength, engine torque, and mechanical efficiency, whereas the gasoline engine’s brake specific fuel consumption (BSFC) decreased by 5.3%–6.5% due to a 1.7%–3.46% improvement in engine mechanical efficiency. Further, emission results showed that the GNP-filled lubricating oil reduced the emissions of the engine by approximately 3%–6% as compared to the virgin lubricating oil. Furthermore, the piston ring wear was found to reduce by using GNP-filled nano-lubricant. The characterization of the worn piston ring surfaces showed that the tribo-film formed on wear tracks resulted in the improved performance of the engine thereby reducing abrasive wear and surface roughness. From these studies, an attempt has been made to co-relate engine performance characteristics with tribological perception to contribute in the direction of energy savings and fuel economy.

Fuel Characteristics

This paper, an abstract of the original, is intended to provide information concerning the present status of Diesel fuel research. The paper is divided into two parts, the first of which concerns the types of fuel in use, describing briefly their sources and properties. A short account is also given of the existing fuel situation and how this may influence future research. Part II deals with the effects of fuel characteristics on engine performance, wear, and fouling. The methods of overcoming any deleterious effects caused by the fuel are discussed, and particular reference is made to the beneficial effects of lubricating oil additives. It must be emphasized that most of the work described refers to the high-speed Diesel engine, owing to the unsuitability of large units for laboratory testing. However, this is beneficial since the high-speed Diesel is most sensitive to fuel characteristics, and it serves to disclose the majority of defects that can arise in a Diesel engine.

Performance And Emissions

Results of study on wear of piston rings, engine performance and exhaust gas emissions of palm oil methyl ester (POME) as a lubricating oil additive in a two-stroke gasoline engine test are presented. Piston ring wear behaviour was monitored as a function of running time. The power output and brake specific fuel consumption of the engine were measured at different speeds. Varnish/lacquer and carbon deposit on the spark plug electrode, cylinder and piston heads as well as exhaust gas (CO2, CO and O2) emission were measured. For comparison purposes, two types of commercial lubricating oils, viz. oil A and oil B were used. The wear resistance of piston rings with POME blending lubrication was found to be greater than the pure commercial oil lubrication. Other results indicate that the POME acts as an additive which improves the engine performance and exhaust emissions of two-stroke gasoline engines.

The Impact

Based on its characteristics, biodiesel has a higher density, viscosity, and acidity level than diesel fuel, so it has a disadvantages in terms of lubricants especially in the long run. The impact, it can decrease the kinematic viscosity of the lubricant, a decrease in the total base number, and the impact by decreased of the engine performance. This research aims to determine the characteristics of lubricants from the use of biodiesel (B20 and B100) related to the kinematic viscosity of lubricants and Total Base Number (TBN). The testing method were used ASTM D2896-15 and ASTM D445-06 standard. The study used two units Kubota RD 65 DI-NB diesel engines with a cylinder volume of 376 cc. The rotary speed of the machine was keep constant at 2200 rpm and were operated for 300 hours non-stop. Moreover, the sampled was carried out every multiple of 100 hours. Based on the research results, the quality of lubricants with B100 fuel is no better than lubricants with B20 fuel. B100-fueled lubricants have kinematic viscosity values at temperatures of 40 °C and 100 °C and has lower TBN values than B20-fueled lubricants.

In the paper researches of influence of using catalyst and polar additives on engine performance and emission of exhaust were carried out. The tests were made on diesel engine DuraTorq-TDDi/TDCi 16v with a capacity of 1998cm3 produced by Ford company. Two additives were investigated: FMAX – catalytic additive to fuel and HDOS – polar additive to lubricating oil in different proportions. The results indicated that using tested additives has a positive effect on exhaust composition (lower concentrations of nitrogen oxides, soot and carbon monoxide) and also decreased fuel consumption.

Monitoring the condition of the engine through oil analysis will help operators to get the most value from their equipment and their lubricant. This is just one part of an overall Preventive Maintenance (PM) Program. Engine lubricant condition reflects the state of health of engine through its properties. Recognition and analysis of the correlation between engine lubricant system based on the lubricant properties and engine performance is crucial to provide insight into engine health. Aim of this paper is an investigation for prior failure of engine component through oil analysis. Engine is the heart of automobile vehicles. Engine performances are directly dependent upon the health of its components like piston, cylinder, cylinder head, crankshaft, cam shaft, connecting rod etc. Metals in lubricating oil can come from various sources, such as wear, contamination and additives. Wear metals result from friction or corrosion of the engine components; for example pistons, bushing, piston ring and bearings, during operation. Contamination can come from dirt, leaks or residual metal pieces. Additives used as detergents, anti-oxidants and anti-wear agents, are added in order to reduce engine wear. Wear of a specific component is heralded by an increase in the concentration of a particular metal, or the sudden appearance of a metal. Since different engine components are composed of different alloys, the increase of a particular metal can be used to identify impending failure of a specific component. An analysis of trace metals in engine oil has permitted the identification of wearing components before severe failure, without dismantling of the engine. Spectrometric Oil Analysis Program (SOAP).

Marine lubricating oil (LO) is deteriorated by contaminants—especially marine gas oil (MGO), which is invariably mixed during its usage—that can damage engine performance. This study investigates a method for determining the content of MGO in lubricating oil. Weight loss from MGO-containing lubricant was evaluated through thermogravimetric analysis (TGA), and a standard calibration curve was plotted to establish a correlation with MGO content. A comparison of the commonly used ASTM–based gas chromatography (GC) analysis, and this TGA approach revealed that the former was more accurate when the lubricant contained ≤1% MGO; however, TGA afforded higher accuracy when the MGO content was between 0.5% and 15%. Hence, TGA can be used as a simple, reliable, and rapid method to analyze the contents of a lubricant contaminant such as MGO.
