Abstract

The invention provides a fuel temperature controlling system and a fuel temperature controlling method, and relates to the engine field. The fuel temperature controlling system comprises a vehicle control device, a detection device and an execution device, and controls the fuel temperature such that an actual value of the fuel temperature is maintained within a certain temperature range based on aresult of the vehicle control device comparing an actual parameter to a set parameter. The fuel temperature controlling method comprises a preset step, a detection step, a process step and a fuel temperature control step, and specifically refers to: setting upper and lower limits of the fuel temperature, comparing a detected actual temperature to the upper and lower limits, and regulating an actual temperature value between the upper and lower limits according to a comparison result. The system and the method can alleviate problems such as low engine efficiency, high fuel consumption and severe emission caused by unstable vehicle engine fuel temperature control in the prior art.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a fuel temperature control system and a fuel temperature control method. Background technique [0002] With the increasingly stringent requirements on vehicle fuel consumption and emissions in various countries, reducing fuel consumption and emissions of automobile engines has become an important issue for major engine manufacturers. Miller cycle, cooling EGR, VVL, in-cylinder water injection, lean combustion and other technologies play an important role in reducing fuel consumption and emission of supercharged gasoline engines. From the analysis of technical feasibility, cost, fuel consumption and emission reduction, etc., Miller cycle and EGR technology are ideal choices, the combination of the two technologies can further reduce engine fuel consumption and emission reduction. [0003] At present, these technologies basically use bench thermodynamics development tests. The var...
