Sequential Exhaust Flow Control. Turbocharger Manifold, System, and Method.
Status: Issued January 2, 2024
Hlava Technologies is raising a $15M Series A to complete supplier-owned validation, manufacturing readiness, and OEM program preparation for the Hlava Sequential Turbocharging Manifold platform. Capital deployment is milestone-driven and aligned with OEM sourcing gates. Mechanical exhaust-energy architecture positioned for platform-level adoption.
The global turbocharger and exhaust manifold markets are large, growing, and tightening regulatory frameworks are accelerating adoption. The STM platform addresses the technical gap at the center of both markets.
Two broad U.S. utility patents covering the manifold apparatus and the exhaust gas control method between turbochargers. Architecture-level utility patent protection covering both apparatus and method.
Two parallel revenue channels generate near-term cash flow while building toward long-term platform licensing with OEMs and Tier-1 suppliers.
Primary long-term revenue through platform licensing and hardware supply agreements with OEM manufacturers and Tier-1 suppliers.
Near-term revenue providing real-world validation data and market proof points for OEM conversations.
Milestone-driven capital deployment aligned with OEM sourcing gate requirements. Each tranche is gated by validation, manufacturing, or program milestones.
Capital is deployed in milestone-gated tranches across six work streams. No capital is at risk ahead of validation checkpoints. Manufacturing transition proceeds only after data confirms production readiness.
A phased path from supplier-owned technical validation to OEM program nomination and licensing execution. Each phase produces deliverables required by the next.
Supplier-owned dyno validation. Emissions-grade instrumentation. Engine transient response characterization. Complete data ownership for OEM sourcing gate submissions.
Investment casting transition. APQP process development. PPAP pathway defined. Cost-down validation against target BOM. Manufacturability confirmed at production volumes.
OEM sourcing gate submission with complete validation package. Tier-1 supplier partnership. Vehicle integration and calibration support. Platform nomination and licensing execution.
Multiple forces are compelling OEMs to solve the same forced induction problem the STM already addresses. The window for platform-level adoption is open.
Tightening transient emissions requirements push manufacturers toward forced induction solutions that deliver boost at lower loads and throttle positions. The STM produces usable boost at 40 to 60% throttle, exactly the operating range where transient emissions limits matter most.
CAFE standards require fuel economy gains across vehicle fleets. Downsized turbocharged engines need immediate response across partial-throttle conditions. The STM enables smaller displacement engines to deliver full-size power without fuel economy penalties.
Variable geometry turbos cost $2,500 to $4,500 per unit and face reliability issues from carbon buildup and heat-related actuator failures. Electrified turbochargers add HV system dependency and thermal management complexity without solving the core transient response problem.
As EV adoption expands, ICE platforms must justify their presence with stronger performance and fuel economy. OEMs carrying ICE powertrains through the transition period need forced induction solutions that differentiate on performance without adding electronic complexity or cost.
Capital, technology, market, and competitive risks are addressed by the structure of the raise, the issued IP position, and the architecture itself.
Two issued U.S. utility patents. Functional validation on a 3.1L V6 platform. ECU and dyno data on file. Operating principles follow established gas law relationships.
Capital deployed in milestone-gated tranches. No capital at risk ahead of validation checkpoints. Manufacturing transition proceeds only after data confirms production readiness.
Aftermarket channel generates revenue and real-world data concurrently. Supplier-owned validation provides iteration speed and data integrity independent of OEM schedules.
Architecture-level utility patent protection creates meaningful barriers. Turbo-agnostic design allows Tier-1 partners to source turbocharger components independently.
Full engineering data packages, validation results, BOM detail, and financial projections are available to qualified investors under NDA. Direct contact with the founder and inventor is available for technical due diligence sessions.
