Embodiment Construction

[0031] The embodiments of the present invention will be further described below in conjunction with the drawings.

[0032] Specific embodiment 1 of the spray diesel coking test simulation device of the present invention, such as Figure 1 to Figure 5 As shown, the spray-type diesel coking test simulation device includes a fuel supply device and a fuel injection nozzle 14 connected with the fuel supply device and has a fuel injection port. The spray-type diesel coking test simulation device also includes an oil circuit simulation pipe 15, an oil circuit The simulation pipe 15 is provided with a heating structure, and the fuel injection port of the fuel injection nozzle 14 is arranged in the inner cavity of the oil circuit simulation pipe 15. In this way, the oil sprayed from the fuel injection nozzle 14 enters the oil circuit simulation pipe 15. The heating structure keeps the oil circuit simulation pipe 15 at a higher temperature, and the oil flows on the inner wall of the oil ci...

Abstract

The invention relates to a spray type diesel coking test simulation device and a diesel detergency detection method. In a coking simulation test, an oil supply device supplies diesel to a diesel spraynozzle; the diesel is sprayed from the diesel spray nozzle to a diesel channel simulation pipe; a heating structure heats the diesel channel simulation pipe, so that an inner cavity of the diesel channel simulation pipe remains at a relatively high temperature; the diesel cokes in the diesel channel simulation pipe and is attached to an inner wall of the diesel channel simulation pipe under the temperature condition. The diesel channel simulation pipe is used for coking the diesel to increase a diesel coking area, so as to improve coking efficiency, obviously shortening detection test time and solve a problem of long time consumption of detection test of diesel detergency in the prior art.

Description

Technical field [0001] The invention relates to a spray type diesel coking test simulation device and a diesel detergency detection method. Background technique [0002] As the number of motor vehicles in my country continues to increase, vehicle exhaust emissions have become the main source of air pollution in my country. In 2016, diesel vehicles only accounted for 10.2% of the national vehicle population, but their NOx emissions were close to 70% of the total vehicle emissions, and PM exceeded 90%. This is mainly because diesel is easy to coke and form deposits at high temperatures, causing the fuel supply system And the nozzle is blocked, resulting in poor diesel atomization, inaccurate air-fuel ratio, and ultimately a larger proportion of pollutants in the exhaust gas. Improving the detergency of diesel or adding diesel detergent can effectively inhibit diesel coking, reduce the formation of deposits, and keep the diesel fuel supply system and nozzles in a cleaner working st...
