Problems solved by technology

[0003] Due to the characteristics of the fuel-saving control strategy of the new energy vehicle hybrid (oil-electric hybrid), the oil-gas mixture will accumulate during the use of the car and cannot be released, resulting in the formation of a high-pressure oil-gas mixture, which poses a safety hazard
The existing technology uses a high-pressure fuel tank to solve this hidden danger, but the use of a high-pressure fuel tank will increase the volume of the carbon tank and add parts such as FLVV valves. The manufacturing process requires high requirements, and it is necessary to upgrade the manufacturing equipment and test equipment, etc., resulting in an increase in cost

Abstract

The invention discloses a fuel evaporation control system for a hybrid electric vehicle. The system comprises a fuel tank and a cooling and dropping device which is connected to the fuel tank for converting fuel steam into liquid fuel. The fuel evaporation control system for the hybrid electric vehicle disclosed by the invention converts the fuel steam in the fuel tank into the liquid gasoline according to a temperature-reducing and pressure-reducing principle, so that the fuel steam fuel in the system is balanced, the high pressure risk in the fuel tank is solved, and the system is small in occupied space. The system works in a relatively sealed environment, so that emission of pollutants is reduced, and emission reaches the national standard VI.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, in particular, the invention relates to a fuel evaporation control system for hybrid electric vehicles. Background technique [0002] In response to the increasingly serious environmental pollution caused by vehicle emissions, the National Environmental Protection Agency issued "Light Vehicle Pollutant Emission Limits and Measurement Methods (China Phase VI)", which added requirements for pollutant control during refueling (emission limit 0.05g / L); The type IV test has tightened the emission limit (from the original 2g / test to 0.7g / test). [0003] Due to the characteristics of the fuel-saving control strategy of the new energy vehicle hybrid (oil-electric hybrid), the oil-gas mixture will be accumulated during the use of the car and cannot be released to form a high-pressure oil-gas mixture, which poses a safety hazard. The existing technology uses a high-pressure fuel tank to s...
