TQC EGI

Efficient Gas Injection

Pre-MVP | Patent Pending

Overview

TQC EGI is a pre-MVP, patent-pending engineering architecture developed by Three Quay Custody LLC.

The system explores controlled electrolytic gas generation and injection as an external subsystem interfacing with existing internal combustion platforms. It is designed to operate without altering base engine geometry and without assuming changes to the host fuel system.

This page provides a public, scope-limited technical overview. It defines design intent and development status only. It does not disclose proprietary mechanisms, operating parameters, control logic, or performance characteristics.

No prototype has been deployed. No testing has been conducted. No performance, efficiency, emissions, or durability claims are made.

The term ‘Efficient’ refers to architectural design intent and system integration objectives, not to measured or validated performance outcomes

Intended Scope

At its current stage, TQC EGI is being designed for theoretical compatibility with platforms capable of supplying suitable high-voltage DC power, including:

• Hybrid petrol vehicles

• Diesel generator sets

• Off-grid and remote power systems

In all cases, TQC EGI is a supplementary system. It does not replace the host engine, fuel source, or control architecture.

System Architecture (Public Summary)

At a high level, the TQC EGI architecture comprises four primary subsystems:

• Electrolytic Gas Generation
  A plate-based electrolytic assembly for in-situ gas production.

• Electrical Power Conditioning and Control
  A bounded electrical layer governing current delivery and enable states.

• Gas Management and Injection
  A low-pressure, immediate-consumption approach with no storage within MVP scope.

• Mechanical Clamping and Isolation
  A mechanically isolated stack designed to maintain sealing, alignment, and electrical separation.

Subsystems are architected to allow independent iteration without cascading redesign.

Detailed geometry, materials, electrical characteristics, and control strategies are intentionally not disclosed.

Design Constraints

TQC EGI is being developed under fixed architectural constraints:

• Retrofit-first
  No internal modification of the host engine.

• External isolation
  Mechanical and electrical separation from engine internals.

• Deterministic behavior
  No adaptive or learning systems within MVP scope.

• Fail-passive operation
  The host platform must remain independently operable.

• Manufacturability focus
  Geometry and assembly methods suited to repeatable fabrication.

Development Status

• Stage: Pre-MVP

• Prototype: None assembled

• Testing: None performed

• Data: None generated

Current work is focused on mechanical stack integrity, sealing strategy, electrical isolation, and manufacturable component geometry.

Intellectual Property

• Status: Patent pending

• Owner: Three Quay Custody LLC

• Disclosure posture: Layered and need-to-know

This public page omits system parameters including gas composition, flow rates, electrical loads, duty cycles, sequencing, and control logic.

Safety and Compliance Position

TQC EGI is not a certified system and has not undergone safety testing or regulatory assessment.

Any future compliance evaluation would occur only following controlled MVP-level validation.

Strategic Context

TQC EGI forms part of a broader infrastructure-grade research and development portfolio focused on energy system resilience, modular engineering architectures, and long-horizon optionality.

Commercial pathways, including licensing, integration, or acquisition, will be evaluated only after MVP-level validation.
