Low Boiling Point Fuel for PHEV CO2 Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydrocarbon fuels developed for full-range internal combustion engines are not optimized for hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs), which generate lower CO2 emissions but require different fuel characteristics to further reduce emissions.
Innovation Solution
A liquid fuel composition with a final boiling point of less than 190°C is used in a spark ignition internal combustion engine within the powertrain of a PHEV, optimizing CO2 emissions reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If conventional hydrocarbon fuels are used in PHEV ICE units, then the vehicle can operate with existing fuel infrastructure, but CO2 emissions are not optimized and remain higher than potential levels
Solution Approach 1:
The patent applies parameter changes by modifying the final boiling point parameter of the fuel composition to be less than 190°C. This specific parameter change optimizes the fuel for PHEV operation, resulting in reduced CO2 emissions compared to conventional fuels. The altered boiling point parameter affects combustion efficiency and fuel consumption patterns in the hybrid vehicle context.
2Object-generated harmful factors
If the final boiling point of fuel is reduced to less than 190°C, then CO2 emissions are significantly reduced, but the fuel formulation deviates from conventional standards
Solution Approach 1:
The patent deliberately changes the final boiling point parameter from conventional values (typically above 190°C) to less than 190°C. This parameter modification creates a new fuel composition regime that optimizes PHEV performance and reduces CO2 emissions while maintaining adequate composition stability for practical use.
