A Diesel Engine Fuel Constant Temperature Purification Management System

Abstract

The invention provides a diesel engine fuel oil constant-temperature purification management system. The system comprises an oil tank, a section-A heat radiation oil conveying pipe, a coarse filter assembly, an output pipe assembly, a section-B heat radiation oil conveying pipe, an oil-water separator, a section-C heat radiation oil conveying pipe, an oil conveying pump assembly, a section-D heatradiation oil conveying pipe, a filter assembly, a section-E heat radiation oil conveying pipe, a purifier and a temperature control unit. For the specific requirement of the fuel oil quality index, the quality index change rule of 5# diesel, 0# diesel, -10# diesel, -20# diesel, -35# diesel and -50# diesel in a normal-temperature state is combined, a temperature regulation and control program forstabilizing the temperature of the diesel and guaranteeing quality to conform to the matching requirement is compiled, through the constant-temperature control using the diesel, the engine fuel oil inlet quality is adjusted and stabilized to be within the range of 0.79-0.84 cm3, so that the maximum power efficiency and the lowest emission index are guaranteed to be exerted under the lowest oil consumption index, and the realization of the green power source is promoted.

Description

technical field [0001] The invention relates to the field of diesel generators, in particular to a diesel engine fuel constant temperature purification management system. Background technique [0002] Statistics from the Ministry of Environmental Protection show that since the reform and opening up, with the rapid increase in the use of various types of diesel vehicles, construction machinery and equipment, marine fishing and breeding diesel ships, nitrogen oxides (NOx), hydrocarbons (HC ) and PM particle emissions are not only the main factors leading to the formation of smog weather and the imbalance of the ecological environment, but also one of the main reasons for the decline in the reproductive rate and production of marine fish. According to statistics, the area of ​​water pollution in the Bohai Sea and the Yellow Sea has reached 24,000 square kilometers in recent years, and marine pollution caused by nitrogen oxides (NOx), hydrocarbons (HC) and PM particles emitted b...

Problems solved by technology

[0005] However, when diesel engines are applied to various fields, the performance of the components of the fuel supply system does not meet the provisions of the GB / T18297-2001 standard. Therefore, the actual fuel consumption rate is not only much higher than the factory measured value, but the exhaust Emissions are much higher than the design index
