Problems solved by technology

[0005] Chinese patent 88102687 discloses a new type of fuel for diesel engines. It uses a vegetable oil catalpa oil as a diesel engine fuel alone or mixed with different types of diesel oil for diesel engines. However, when catalpa oil is mixed with different types of diesel oil , the temperature difference required for use is relatively large, between -12°C and 25°C, and there is also a limit to the operating time of the diesel engine, which makes the use of new fuels for this diesel engine very limited.

Embodiment 1

[0020] Embodiment 1: the component of the weight percent of biofuel mixture consists of: jatropha oil 20%, diesel oil 77%, methyl alcohol 3%, and described diesel oil is 0% # Diesel oil, jatropha oil, diesel oil, methanol mixture, need to add surfactant, surfactant is made up of oleic acid, ethyl lactate, diethanolamide, isooctyl nitrate, their percentage by weight is oleic acid 25%, lactic acid Ethyl ester 15%, diethanolamide 5%, isooctyl nitrate 55%. The weight ratio of jatropha oil, diesel oil, methanol mixture and surfactant is 10:1000.

[0021] The jatropha oil fuel mixture prepared in the above ratio is mixed with 0 # Diesel oil is carried out comparative test: according to national authoritative organization quality supervision inspection station will contain the biofuel mixture of 20% jatropha oil and the 0 # Diesel oil is carried out comparative test, and the result shows, jatropha biofuel mixture can guarantee diesel engine to work normally, and jatropha biofuel mi...

Embodiment 2

[0031] The composition of the weight percent of biofuel mixture is: jatropha oil 30%, diesel oil 60%, ethanol 10%, and described diesel oil is 0% # Diesel oil, jatropha oil, diesel oil, ethanol mixture after adding ethanol, need to add surfactant, surfactant is made up of oleic acid, ethyl lactate, diethanolamide, isooctyl nitrate, and their weight percent is oleic acid 25%, ethyl lactate 15%, diethanolamide 5%, isooctyl nitrate 55%. The weight ratio of jatropha oil, diesel oil, ethanol mixture and surfactant is 50:1000.

[0032] The jatropha biofuel mixture prepared in the above ratio was mixed with 0 # Diesel oil is carried out comparative test: the biofuel mixture containing 30% jatropha oil and the 0# Diesel was carried out comparative test, and the results showed that the Jatropha biofuel mixture and 0 # Compared with diesel as fuel: its power increases by 2% on average, the fuel consumption (specific fuel consumption) of load characteristics increases by 2% on average,...

Abstract

The invention discloses a Manioca biological fuel mixture which is prepared by mixing Manioca oil with different types of diesel oil, wherein the fuel mixture is charged by alcohols and surface-active agents, each of the physical and chemical indexes of the mixture reaches or exceeds that of 0# diesel oil.

Description

[0001] Field [0002] The invention relates to fuel for diesel engines, in particular to a jatropha biofuel mixture. Background technique [0003] The main fuel used by existing diesel engines is petroleum diesel. Because it is derived from petroleum, petroleum is a non-renewable resource. With the increase in the number of diesel engines, petroleum resources are constantly decreasing, and the release of diesel combustion products causes air pollution. At present, The annual production of new cars in the world is about 50 million, and the number of cars in the world is about 750 million (including motorcycles). With the rapid development of the automobile industry, the consumption of gasoline and diesel has increased with the increase in the number of automobiles, which has also brought about problems such as automobile exhaust pollution. In the past 20 years, although great progress has been made in improving the oil combustion process and exhaust gas purification, they stil...
