AbstractThis study investigates the development of novel montmorillonite/castor oil blends to formulate sustainable lubricating greases to promote the replacement of petrochemicals industry-derived materials by substances obtained from renewable sources. Specifically, the effect of the thickener concentration on the rheological, chemical, thermal, tribological properties, and atomic force microscopy (AFM) microstructure of these systems were studied. The results showed that the C20A nanoclay content could be used to modulate the viscosity values, the linear viscoelastic functions, and tribological properties of these montmorillonite dispersions. In general, these gel-like dispersions exhibited remarkable lubricant properties; the samples showed values of the friction coefficient and wear scars similar or lower than those obtained with model bentonite grease.

In the present scenario owing to the depletion of fossil fuel and at the same time increase in demand averts the researchers towards the alternative fuel. Various investigation is being carried out to find the most suitable alternate for the fossil fuel in IC engine, which satisfies the demand, improves the performance and decreases the emission. This paper deals with the dual fuel mode. Tests were performed at single cylinder fore stroke dual fuel diesel engine with blends of acetylene in different proportions (0.199 kg/hr,0.394 kg/hr and 0.588 kg/hr) with 20% waste cooking oil at a rated injection pressure of 200bar.The result shows the increased in BTE and decreased BSFC and exhaust gas temperature, furtherance the decrease in NOx and CO are observed as the amount of acetylene increases. BTE increases because of lower auto ignition temperature and high calorific value of acetylene. Graphs were obtained based on the performance of the engine and B20 with 0.394 kg/hr of acetylene is concluded to be optimum, B20 with 0.199 kg/hr shows the result similar to diesel operation, at B20 with 0.588 kg/hr the increase in the knocking effect was observed.

Over the last years extensively research has been carried out on full or partial substitution of supplies resources coming from renewable resources on traditionally non-renewable, in the case of the automobile sector there are progresses in bio-combustibles (biofuel) and synthetic oils coming from vegetable sources. There are strong efforts to find oil additives which can improve oils features in automobile industry, by adding vegetables oils to commercial lubricant oils, is expected to improve oil thermal stability.  In the present research, different ratios of castor oil (ricinus comunis)-motor oil blends were obtained and their thermal properties were characterized by using the so-called Back and Front Photopyroelectric (BPPE/FPPE) techniques. Several oil-additives concentrations were measured and thermal diffusivities and effusivities as well as densities are reported, getting full thermal characterization for every concentration.

Flame Ionization

The presence of aldehyde in the exhaust gas of a stationary, direct injection, compression ignition engine operating with castor oil biodiesel/diesel oil blends (B5, B10, B20 and B35) is analyzed. The diesel engine was operated with constant speed of 1800 rev/min and load of 37.5 kW. The gas sample was collected directly from the exhaust. Aldehydes were identified and quantified using gas chromatography (GC) with flame ionization detector analyzer (FID). Acetaldehyde presented higher exhaust concentration than formaldehyde for all fuel blends tested. In general, the exhaust aldehyde levels were very low and did not present significant differences between the fuel blends tested.

Test Outcomes

Importance of this investigation is 100% biodiesel make use as fuel for low heat rejection (LHR) diesel engine. Due to this reason bio-fuels namely, eucalyptus oil and paradise oil were selected and used as dual fuel. Conventional engine hardware parts were coated with lanthana-doped yttriastabilized zirconia (the doping of YSZ coatings with small amount of La2O3) with a thickness of 300 µm, so as to analyze the operating parameters of paradise oil–eucalyptus oil blends. Tests run were replicated on the conventional diesel engine and outcomes were compared. Test outcomes confirmed that the major intention of this research was attained as engine operating parameters like, brake thermal efficiency, exhaust gas temperature were increase with decrease of fuel consumption. In addition, engine emissions of HC, CO and smoke were reduced with exception of NOx for LHR diesel engine than conventional engine.

Pyrolytic Oil

Pyrolysis of castor oil with anhydrous sodium hydroxide as a catalyst was performed to produce Catalytic Castor pyrolytic oil (CCPO). The physical and chemical properties of the pyrolytic and gas oils were recorded according to ASTM standards. Gas oil was blended with castor pyrolytic oil at different volumetric ratios of 0%, 25%, 75%, and 100% as CCPO00, CCPO25, CCPO75, and CCPO100, respectively. Coefficient of variation (COV) of combustion parameters proved to be a profound method of assessing combustion characteristics and engine performance. COV of combustion parameters (IMEP, Pmax, and dP/dΘmax) for gas oil blends with pyrolysis oil were measured. Recorded pressure crank angle traces of 150 consecutive cycles were used for COV’s determination. A single cylinder diesel engine equipped with calibrated measuring techniques was used at different engine loads. Higher volumetric blending ratios of pyrolytic oil with diesel oil increased the COV’s within an acceptable range of engine operating conditions. Minor modifications might be valuable for engines fueled by pyrolysis oil blends to obtain smoother, lower noise operation, and combustion stability.
