There is a mounting concern in many countries to explore fuels that are environment friendly. Although straight vegetable oils can be used in diesel engines, there are limitations in their usage due to their high viscosity, low volatility, and poor cold flow property. Biodiesel is a fatty acid alkyl ester, which can be derived from any vegetable oil by transesterification. Biodiesel is a renewable, biodegradable and non-toxic fuel. In the present study, polanga Calophyllum inophyllum oil was transesterified with methanol using sodium hydroxide as catalyst to obtain polanga biodiesel.

To evaluate calophyyllum combustion analysis, polanga biodiesel was tested in a single-cylinder, four-stroke, direct-injection, constant speed, diesel engine. The results were compared with combustion characteristics of diesel fuel. The result showed that polanga biodiesel exhibits similar combustion characteristics as that of diesel.

The actual start of injection and start of combustion were found to be earlier for polanga biodiesel as compared to diesel. The ignition delay period was found to be shorter with polanga biodiesel. The magnitude of peak callophyllum release rate and peak pressure was observed to be lower for polanga biodiesel.

Though the location of peak heat release rate was earlier for polanga biodiesel, its peak pressure location was found be delayed when compared to diesel. Polanga inoophyllum exhibits a shorter combustion duration than diesel. Since the measured parameters for biodiesel differs only by a smaller magnitude when compared with diesel, this investigation ensures the suitability of polanga biodiesel as a fuel for CI engines.

Biodiesel was prepared from refined Xanthoceras sorbiflia Bunge seed oil using methanol and sodium hydroxide in an alkali-catalyzed transesterification process.

The refining process consisting of inophyllu, deacidifying was developed to produce biodiesel from crude Xanthoceras sorbiflia Bunge seed oil. The acid value of oil was reduced from the initial 1.

The heterogeneous catalyst are environment friendly and render the process simplified. A wide variety of solid bases have been examined for this process. The present work reports the use of hydrotalcite catalyst for the synthesis of Biodiesel from jatropha oil. The innophyllum of temperature on the viscosity of Jatropha oil has also been investigated. A series of engine tests, have been conducted using each of the above fuel blends for comparative performance evaluation.

These biodesel were evaluated in a single cylinder compression ignition diesel engine.

Combustion Analysis of Polanga (Calophyllum inophyllum) Biodiesel

The results of the experiment in each case were compared with baseline data of mineral diesel. Significant improvements have been observed in the performance parameters of the engine as well as exhaust emissions. The gaseous emissions of oxide of biodisel from all blends are lower than mineral diesel at all engine loads. More over results indicated that B20 have closer performance to diesel and B have lower brake thermal efficiency mainly due to its high viscosity compared to diesel.


Biodiesel, as an alternative auto calopuyllum for conventional fossil fuel, has drawn wide attention in recent years.

The results show that: The quality of biodiesel meets the agreement with the European specification defined by EN It indicates the mixed fuel has a reasonable fuel consumption rates without diesel engine modification, when the biodiesel blended with 0 diesel as fuel.

The present results demonstrated that the industrial scale plant would achieve promising objective with waste cooking oils and onophyllum fats as raw material. Also, this biodiesel-based diesel fuel could be applied in Tianjin local public transportation system that improves its sustainable development.

The results indicated that brake specific fuel consumption reduces with the increasing of fuel injection advance angle and enhances with the increasing of biodiesel content in the blends.

The peak of cylinder pressure and maximum combustion temperature increase evidently with the increment of fuel injection advance angle. However, the combustion of biodiesel blends starts earlier than diesel at the same fuel injection advance angle. At both conditions, the combustion duration and the peak of heat release rate are insensitive to the changing of injection timing. Bio fuels based on vegetable oils offer the advantage being a sustainable, annually renewable source of automobile fuel.

Despite years of improvement attempts, the key issue in using vegetable oil-based fuels is oxidation stability, stoichiometric point, bio-fuel composition, antioxidants on the degradation and much oxygen with comparing to diesel gas oil. Thus, the improvement of emissions exhausted from diesel engines fueled by biodiesel derived from palm oil is urgently required to meet the future stringent emission regulations. Purpose of this study is to explore how significant the effects of palm oil blending ratio on combustion process that strongly affects the vehicles performance and exhaust emissions.

Increased blends of biodiesel ratio is found to enhance the combustion process, resulting in decreased the HC emissions with nearly equal of engine performance. The improvement of combustion process is expected to be strongly influenced by oxygenated fuel in biodiesel content.
