INNOVATION

Sleeve valve engine design advantages can now be exploited using modern materials, engineering practices, computer-aided manufacturing, and modeling, to optimize engine performance.

SVE Technologies is focused on compression ignition, turbocharged engines that maximize performance and reliability, while minimizing environmental impact.

 

Key Performance Parameters

  • High compression, low complexity, turbocharging, modern materials and advanced manufacturing techniques promise to extend the power to weight ratios advantages seen in earlier SVE production engines.

  • BMEP is proportional to the engine combustion pressure. This is directly proportional to torque. BMEP is one measure of efficiency, high BMEP indicates higher power-to-weight and power-to-volume. For 4-stroke engines, typical BMEP values are:

    * Target SVE BMEP 260-290 PSI

  • MTBO is a measure of engine durability. It is design parameter for engine components, materials, and production techniques, proven in service. Unmanned Aircraft Systems (UAS) engine design may trade MTBO in pursuit of high power-to-weight ratio. The SVE target MTBO is 1500 hours.

  • The SVE compression ignition advantage and turbocharging are combined to minimize fuel consumption, that will meet or exceed the 0.33 lb/hr ratings seen in state of the art applications.

  • Flight engines are among the most costly to operate. Three factors dominate cost of ownership:

    • Initial

    • Replacement/Overhaul Cost

    • Operation costs – Fuel/Oil/Maintenance

    The sleeve valve engine addresses all of these by reducing initial cost by virtue of low parts count, maintain a high TBO relative to other engines, and through low fuel consumption and minimal maintenance.
