Case 12864

Reformer Enhanced Direct Injection Methanol Engines

Keywords:

Internal combustion engine, efficiency gain, biofuel

Applications:

    Increase engine efficiency and operation efficiency

Problem:

    Low efficiency of biofuels in conventional engine

Technology:

The invention enhances the engine operation performance of biofuels of a methanol-fueled engine by addition of hydrogen-rich gas which is produced by reforming a fraction of the methanol. The highly turbocharged, high compression ratio operation is also facilitated by the exceptionally high knock resistance of methanol when it is directly injected. Thus the total efficiency gain relative to a conventional gasoline engine could be greater than 40%.

Advantages:
  • Increases engine efficiency at high loads
  • Reduce friction loss during operation
  • Improve combustion stability in spark ignited engines
  • Suppress pollutant emissions
