MHF is produced by physically blending and microemulsifying various ratios of plant oil with diesel fuel in the presence of an additive, which could be composed of cetane enhancers, viscosity reducers and/or emulsifiers. A blend of 30% plant oil and 70% diesel fuel is called MHF30 while a blend of 50% plant oil and 50% … Read More

Fuels produced using microemulsification technology are called “hybrid Fuels”. They are called ionic or non-ionic depending on the type of surfactant present. For example, those hybrid fuels containing a basic nitrogen compound are termed ionic while those consisting only of plant oil, aqueous ethanol, and another alcohol, such as 1-butanol, are termed non-ionic or detergentless … Read More

The interest in biodiesel as an alternative transportation fuel stems mainly from its renewable, domestic production, its safe, clean-burning properties, and its compatibility with existing diesel engines. Biodiesel can be blended with petroleum diesel in any percentage. The percentages are designated as B1 for a blend containing 1% biodiesel and 99% petroleum diesel, B20 for … Read More

responsible for the popularity of the transesterification method for reducing the viscosity related problems of plant oils. The popularity of methyl esters has contributed to the term “biodiesel” now usually referring to plant oil esters and not neat plant Oils. It was shown that in homogeneous catalysis, alkali catalysis is a much more rapid process … Read More

The feedstock comprising a mixture of various waste plant oils recovered from restaurants and other sources is fed into a vessel with metal filter to remove undesirable materials. The filtered oil accumulates at the bottom of the vessel and is transferred by a gear pump to the Feed Tank up to the level of about … Read More

During the process of transesterification, an alcohol (such as methanol) reacts with the triglyceride oils contained in plant oils, animal fats or recycled greases to form fatty acid alkyl esters (biodiesel) and glycerin. The reaction requires heat and a strong base catalyst such as sodium hydroxide or potassium hydroxide. The simplified chemical reaction is shown … Read More

The Greasecar Vegetable Oil Conversion System is an auxiliary fuel modification system that allows diesel vehicles to run on plant oil in any climate. The Greasecar kit comes with everything needed to convert a diesel vehicle to run on straight plant oil, including an aluminum heated fuel cell, quick-flush switching, and 10 micron filter. The … Read More

With the preponderance of evidence from numerous studies showing the unsuitability of using pure or straight plant oil for long-term use as diesel fuel substitute in unmodified modern CI engines, researchers have focused on using various blends of different plant oils with diesel fuel. There are basically two parameters that can be changed or adjusted: … Read More

An excellent review of literature concerning the use of various kinds of plant oils as a replacement for diesel fuel was made by Jones and Peterson of the University of Idaho. Pryde (1982) also reviewed the results of a number of studies on the use of plant oils as a diesel substitute and reported that … Read More

Timing, pressure and quantity of fuel delivery are crucial for efficient combustion. The important task of fuel delivery is performed by the fuel injection Equipment. Mechanically-Controlled Fuel Injection Fuel is supplied to the injector by an injector pump. The injector pumps are mechanically driven from the crankshaft. The drive from the crankshaft is set so … Read More
