Positioning in today’s energy transition
Electrification is accelerating, yet many duty cycles (heavy‑duty transport, marine, rail, remote power, and peaking/backup generation) remain hard to electrify in the near term due to energy density, infrastructure, cost, and uptime constraints. These segments will continue to rely on combustion or hybridized combustion for years. Advancing classical mechanics—higher cycle work, lower friction, and better in‑cylinder control—can reduce fuel and pollutant intensity now, while complementary low‑carbon fuels and storage scale.

Primary segments

• Heavy‑duty road: tractors, vocational trucks, buses (diesel/SI/dual‑fuel).
• Stationary power: microgrids, industrial CHP, backup/peaking gensets.
• Marine/rail auxiliaries and off‑road equipment.
• Hybrid range extenders for commercial vehicles.

Why these segments

• Demand high torque at lower RPM, long life, and predictable maintenance.
• Operate under fuel‑/emissions‑capped rules but require reliability and fast refuel.
• Benefit from efficiency gains without wholesale platform changes.

The items below are supported by internal/third‑party CFD and system models; all require hardware validation and certification testing.

• Performance across speed range. Increased indicated work at lower mean piston speed (every‑cycle internal charging).
• Fuel economy. Pathway to lower BSFC → improved operating margins for end users.
• Acoustics & heat. Potential for lower block‑borne noise and reduced heat rejection at a given brake load.
• Emissions. In‑cylinder mixture/temperature control to lower NOx/CO/PM or reduce aftertreatment burden.
• Packaging & cost per torque. Opportunity to meet torque with smaller displacement or fewer cylinders; simplified external air‑handling.
• Durability & maintenance. Lower RPM for the same work target → reduced inertial loads and FMEP, with potential maintenance benefits.

For fleets/operators

• Total cost of ownership (TCO): fuel, maintenance, uptime, resale.
• Compliance: emissions and noise limits without exotic aftertreatment.
• Availability: parts and serviceability.

For OEMs/engine makers

• Integratability: fits existing manufacturing envelopes.
• Scalability: applies to multiple displacements/ratings.
• IP/licensing: clear rights, low friction technology transfer.

RME value

• Targets TCO reduction via lower fuel and maintenance at equivalent duty.
• Delivers torque at lower RPM, enabling taller gearing or fewer cylinders.
• Provides a compliance pathway by improving in‑cylinder control, with standard aftertreatment as needed.

1. Retrofit & pilot stationary — single‑cylinder demo → 25–100 kW genset pilot with independent emissions/efficiency reports.
2. Niche vehicle pilots — vocational trucks/buses with hybrid RME range extenders; duty cycles with predictable routes.
3. Scale into heavy duty — OEM programs for road, marine auxiliary, and rail applications.

Why start stationary/niche: controlled duty cycles, simpler certification, and clear, metered fuel savings make ROI easy to prove.

Improving the efficiency of the existing combustion base can reduce fuel consumption and exposure to price shocks while the grid and supply chains for electrification mature. RME is positioned as a bridge technology that raises delivered kWh per unit of fuel in segments where combustion will persist during the transition.

• Dyno: IMEP/BMEP/BSFC maps; PRR/PCP limits; motored FMEP.
• Emissions: NOx/CO/HC/PM/PN on standardized cycles.
• NVH & thermal: dBA, vibration spectra, coolant/oil heat load.
• Reliability: endurance hours, teardown inspection, wear.
• Field trials: fuel metering, uptime, maintenance intervals, driver feedback.
• Lifecycle: preliminary LCA and cost‑per‑mile/kWh analyses.
