Problem
Current renewable fuel technologies face challenges in meeting the increasing demand for long-range heavy transportation due to limitations in fuel supply, high production costs, and the need for engines suited to use these fuels, particularly for trucks and ships, which require substantial amounts of fossil fuels.
Innovation Solution
Development of a methanol-ethanol blend fuel that is low-cost, high-volume, and low-emission, compatible with existing infrastructure, and designed for high-compression engines, including the General Cycle engine, to achieve higher power output and efficiency, with optional additives for improved lubricity and ignition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If unblended fuel compounds or single fuel compounds are used, then fuel supply limitations are reduced, but production costs increase and emissions requirements are not met
Solution Approach 1:
The patent combines multiple renewable alcohol fuels (methanol, ethanol, propanol, butanol) into a blended fuel composition. This merging approach allows the fuel blend to meet emissions requirements while maintaining production cost-effectiveness and adequate supply, resolving the contradiction between fuel quantity and manufacturing ease.
Solution Approach 2:
The invention creates a composite fuel material by blending different alcohol compounds with specific properties. Each alcohol component contributes different characteristics (octane rating, energy density, combustion properties), and their composite formulation achieves compliance with emissions standards while maintaining economic viability and supply adequacy.
2Object-generated harmful factors
If renewable fuels are blended with fossil fuels, then emissions requirements are partially met, but net CO2 emissions are not sufficiently reduced
Solution Approach 1:
The patent extracts and eliminates fossil fuel components from the fuel composition, using exclusively renewable alcohol-based fuels. This extraction of harmful fossil fuel elements achieves both emissions reduction and net CO2 emission reduction, as all components (methanol, ethanol, propanol, butanol) are derived from renewable biomass sources.
3Power
If compression ratios are increased to 10-18, then power output efficiency increases, but engine design complexity increases
Solution Approach 1:
The patent changes the fuel composition parameters (using specific blends of alcohols with appropriate octane ratings and combustion characteristics) to enable high compression ratio operation. The alcohol-based fuel blend is specifically formulated to withstand and utilize high compression ratios of 10-18, achieving superior power output efficiency while the engine design complexity is managed through targeted parameter optimization.
