Mystere Engine (MRE)
1/8th the parts, 1/3rd the cost, 42–45% thermal efficiency.
Executive Summary
Mystère Engine (MRE) has developed a proprietary leveraged-crank, rotary-valve internal combustion engine built on the Atkinson-Diesel thermodynamic cycle. The Mystère engine achieves ~60% brake thermal efficiency—nearly double conventional diesels—while burning 15+ fuel types including hydrogen, natural gas, diesel, ethanol, and powdered biofuels. A cam-less rotary valve replaces the traditional valve train, reducing component count by 90%.
The Problem
The global ICE fleet operates at 25–35% thermal efficiency, wasting the majority of fuel energy as heat. Conventional poppet-valve architectures require hundreds of precision components that drive manufacturing cost, maintenance burden, and ~12% friction losses at idle. With fossil fuel depletion accelerating and emissions mandates tightening, the industry needs a step-change in efficiency—not incremental improvement.
The Solution
The Mystère engine combines three breakthroughs: (1) an Atkinson-Diesel cycle with 35:1 compression and 42:1 expansion ratio for maximum thermodynamic efficiency; (2) a leveraged-crank delivering 2–5x torque of comparable diesels, eliminating the transmission; and (3) a rotary valve with carbon end seals consuming <2% of power versus 12% in conventional engines. Scalable from 34 kW automotive units to 2+ MW distributed power generators.
Strategic Advantages
Proprietary leveraged-crank and rotary-valve IP. 1/8th the parts, 1/3rd manufacturing cost, 1/10th overhaul cost versus diesel. 15-fuel flexibility including hydrogen-ready operation. Ultra-low emissions via lean burn and HOH injection. Exceeds steam turbine efficiency by >25% and poppet-valve diesels by 18%. Could double vehicle fuel economy (35 → 70 mpg), saving ~17 million barrels of oil per day globally.
Market Opportunity
The global ICE market is ~$316B in 2025, projected to reach $425B by 2030 (6% CAGR). Distributed power generation exceeds $80B. The current best-in-class diesel achieves only 53% thermal efficiency (Weichai, 2024)—MRE's 60% platform represents a clear technological moat. Hydrogen ICE adoption is accelerating as a bridge between fossil fuels and full electrification.
Execution Readiness
Engine concept validated through peer-reviewed publication and detailed thermodynamic modeling. Leveraged-crank mechanism and rotary valve design complete. Platform scalable across automotive, marine, and stationary power. Dual-use commercial and defense potential for multi-fuel distributed generation.
