Multi-port Engine Combustion Chamber Cyclone Swirl
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internal combustion engines face challenges in increasing power without expanding their size, improving fuel atomization for stable idle and performance, providing sufficient power and torque under light loading, and avoiding soot and carbon deposits that can lead to faulty EGR system issues.
Innovation Solution
The engine design incorporates a vertically inverted intake cone and horizontal intake nozzles that direct the air-fuel mixture to swirl in a cyclone motion within the combustion chamber, increasing power through enhanced fuel atomization and reburning, and features a variable compression ratio to adjust inlet pressure and compression ratio under varying loads, avoiding soot and carbon deposits by using a structure with ramps to swirl the mixture before compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the number of valves per cylinder is increased to produce more power, then engine power increases, but the valve diameter must be reduced due to dimensional constraints
Solution Approach 1:
The single large valve is segmented into multiple smaller valves (intake and exhaust valves) arranged around the combustion chamber. This segmentation allows the total valve area to remain sufficient for power generation while each individual valve maintains an adequate diameter for proper function.
Solution Approach 2:
The valve arrangement transitions from a single central valve to a multi-valve configuration distributed in different spatial positions around the combustion chamber. This dimensional redistribution allows more valves to fit within the same overall dimensions without compromising individual valve size.
2Device complexity
If traditional vacuum compression is used to operate the engine, then the engine structure is simple, but fuel atomization is poor resulting in unstable idle and higher fuel consumption
Solution Approach 1:
A multi-port fuel injection system is introduced as an intermediary mechanism between the air-fuel mixture intake and the combustion chamber. This system includes multiple fuel injectors positioned at different locations that spray fuel directly into the combustion chamber, improving atomization quality without fundamentally changing the vacuum compression operation.
Solution Approach 2:
Fuel injection is applied locally at multiple specific positions within the combustion chamber rather than relying on uniform vacuum distribution. Each fuel injector targets a specific region, creating locally optimized fuel-air mixing zones that collectively improve overall combustion quality and stability.
3Power
If turbochargers or superchargers are used to increase inlet pressure for higher power output, then power output increases, but the fuel/air mixture detonates rather than burns
Solution Approach 1:
Fuel is injected and atomized in advance before compression, and the air-fuel mixture is prepared with proper stoichiometric ratios beforehand. This preliminary preparation ensures that when compression occurs, the mixture burns smoothly rather than detonating, even at higher inlet pressures.
Solution Approach 2:
The fuel injection timing, quantity, and distribution are dynamically adjusted to change the fuel-air ratio parameters. By optimizing these parameters, the mixture remains within the explosive range rather than entering the detonation range, allowing higher compression pressures without harmful detonation.
4Object-affected harmful factors
If the compression ratio is decreased to prevent detonation, then detonation is avoided, but power and torque under light loading are insufficient
Solution Approach 1:
The fuel injection system dynamically adjusts the fuel-air ratio based on operating conditions. Under light loading, the system maintains a higher fuel content in the mixture to prevent detonation while still achieving adequate power output, and under heavy loading, it optimizes for maximum power while avoiding detonation through controlled compression.
Solution Approach 2:
The air-fuel ratio parameter is changed based on loading conditions. Under light loading, a richer mixture is used to prevent detonation while maintaining power, and the compression ratio is optimized to balance detonation prevention with power generation across different operating regimes.

AI summary
The present invention allows the air-fuel mixture to swirl in a combustion chamber to increase the power from the engine. Each engine cylinder contains a piston, a combustion chamber, and at least one intake valve, exhaust valve, and spark-plug. Also, the top of the piston head contains a hole that forms the entry point of a converging nozzle, where the air-fuel mixture is first directed downwards and then horizontally through intake nozzles onto ramps located on the inner walls of the combustion chamber that allows the air-fuel mixture to swirl in a counter-clock wise motion. This swirling effect causes a cyclone inside the combustion chamber that when ignited it results in an additional explosive force that drives the piston downwards with additional acceleration, which increase the power produced by the engine.
