Solution Overview

Problem

Internal combustion engines face inefficiencies in fuel combustion, leading to lower gas mileage and increased emissions, as they rely on a precise fuel/air mixture that is not optimized for maximum efficiency.

Innovation Solution

A device is attached to the oil filler port of internal combustion engines, allowing additional fresh air to enter the engine's oil system through a tubular chamber with an air inlet and outlet, using a condensation chamber and baffles to prevent oil leakage, enhancing the fuel/air mixture during the combustion stroke without requiring additional electronics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If additional fresh air is introduced into the combustion chamber, then engine efficiency and fuel burn improve, but the fuel/air mixture precision deteriorates

Engineering Contradiction:

Improveengine efficiencyVSAvoidfuel/air mixture precision

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The oil system serves as an intermediary pathway to introduce additional fresh air into the combustion chamber. The device connects to the oil filler port and uses the existing oil system infrastructure as a mediator to deliver air to the combustion stroke, bypassing the need to modify the primary fuel injection system while maintaining combustion efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The oil system is given a multi-functional role by using it not only for lubrication but also as an air intake pathway for the combustion chamber. This universal utilization of existing system infrastructure allows additional air introduction without adding separate dedicated air delivery systems, thereby improving engine efficiency while avoiding complex modifications.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If a device is added to the oil filler port to introduce fresh air, then engine efficiency improves, but device complexity increases

Engineering Contradiction:

Improveengine efficiencyVSAvoiddevice structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The invention merges the air introduction function with the existing oil filler port structure. The device integrates multiple functions (air intake, condensation chamber, baffles, and connection mechanism) into a single unified component that attaches to the oil filler port, reducing overall system complexity compared to adding separate independent systems for each function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device employs a nested structure where the condensation chamber is positioned within the main body, baffles are nested inside the chamber, and the entire assembly fits within the space provided by the oil filler port opening. This nested arrangement minimizes the device's external dimensions and reduces spatial complexity while maintaining all necessary functional elements.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Productivity

If air is introduced through the oil system, then fuel/air mixture efficiency improves, but oil leakage increases

Engineering Contradiction:

Improvefuel/air mixture efficiencyVSAvoidoil leakage

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The device converts the potential harmful effect of pressure differentials that could cause oil leakage into a beneficial condensation mechanism. The condensation chamber and baffles are designed to capture and return oil that might otherwise leak, transforming what could be a loss into a recovery system that maintains oil levels and prevents leakage.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The device recovers oil that separates from the air/fuel mixture in the condensation chamber and returns it to the oil system through the baffles. This recovery mechanism prevents oil loss and leakage by capturing and redirecting oil that would otherwise be discarded or leak out of the system during the air introduction process.

Inventive Principle:

Principle #34Discarding and recovering
