Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fuel oil generators have high noise levels, complex structures leading to high failure rates and maintenance costs, and inefficient fuel consumption, especially for small output power applications, due to atmospheric combustion processes that are uncontrollable and result in incomplete fuel combustion and black smoke emissions.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If atmospheric combustion is used in fuel oil generators, then fuel combustion can occur, but incomplete combustion occurs and black smoke is emitted
Solution Approach 1:
The patent applies preliminary action by pre-mixing vaporized fuel with air in precise proportions before combustion occurs. The fuel is vaporized and mixed with the optimal amount of air (1:15 ratio) in advance, ensuring complete combustion and preventing black smoke emission.
Solution Approach 2:
The patent changes the parameters of the combustion process by controlling the fuel-to-air ratio precisely at 1:15, maintaining optimal combustion conditions. This parameter control ensures complete combustion and eliminates harmful emissions.
2Power
If conventional fuel oil generators are used, then power generation is achieved, but noise level is high (more than 80 dB)
Solution Approach 1:
The patent replaces the mechanical combustion system with a controlled chemical reaction system. By using precise fuel vaporization and premixed combustion, the system eliminates the mechanical noise associated with conventional generators while maintaining power generation capability.
3Power
If fuel oil generators operate at minimal power output, then small power needs are met, but fuel consumption does not decrease proportionally
Solution Approach 1:
The patent changes the operational parameters by maintaining optimal fuel-to-air ratio (1:15) even at minimal power output. This ensures efficient combustion and proportional fuel consumption reduction, unlike conventional generators that maintain minimum fuel consumption regardless of load.
4Ease of manufacture
If conventional combustion systems are used, then fuel combustion occurs, but combustion is uncontrollable and efficiency is low
Solution Approach 1:
The patent implements feedback control by monitoring and adjusting the fuel-to-air ratio to maintain the optimal 1:15 proportion. This feedback mechanism ensures complete combustion, high efficiency, and controllable combustion process.
Solution Approach 2:
The patent optimizes combustion efficiency by precisely controlling the fuel-to-air ratio parameter at 1:15, ensuring complete combustion and maximum energy extraction from the fuel.
