Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Carbureted and fuel-injected engines face challenges in optimizing power production while maintaining fuel economy and controlling emissions, with ambient and engine temperature affecting performance.
Innovation Solution
A finned spacer is thermally coupled between the intake manifold and the carburetor, utilizing high thermal conductivity materials to dissipate heat from the intake manifold into ambient air, reducing thermal energy transfer to the carburetor and improving the energy content of the fuel charge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If fuel is consumed at high rates to produce large amounts of power, then power production is improved, but fuel economy deteriorates and emissions worsen
Solution Approach 1:
The patent changes the temperature parameter of the fuel charge by introducing a thermally coupled spacer that actively cools the intake manifold. This parameter change allows the engine to maintain higher power output while improving fuel economy, as cooler fuel charges enhance combustion efficiency and reduce energy losses.
2Temperature
If ambient and engine temperatures are high, then engine operation is maintained, but power production is reduced
Solution Approach 1:
The patent introduces a spacer as an intermediary component between the intake manifold and the carburetor. This spacer acts as a thermal mediator that actively manages heat transfer, cooling the fuel charge while allowing the engine to operate in high ambient temperature conditions, thereby maintaining power production.
3Temperature
If thermal energy is transferred to the carburetor from the intake manifold, then the carburetor operates, but the energy content of the fuel charge is reduced
Solution Approach 1:
The patent extracts thermal energy from the fuel charge by introducing a thermally coupled spacer that conducts heat away from the intake manifold and carburetor interface. This extraction of thermal energy preserves the energy content of the fuel charge, improving overall engine efficiency.

AI summary
A finned engine spacer is coupled in thermal communication between an intake manifold and a fluid metering device. The spacer includes a body having an upstream face, an opposed downstream face, and sides extending between the upstream and downstream faces, the sides cooperating to form an outer periphery. A bore is formed through the body from the upstream face through to the downstream face, the bore for communicating a fuel charge from the fluid metering device to the intake manifold. Fins are formed in each of the sides, and the fins extend between the bore and the outer periphery, creating a finned engine spacer.
