1. A method of operating a direct injection diesel cycle internal combustion engine, comprising introducing a gaseous fuel mixture directly into a combustion chamber of said engine, wherein said gaseous fuel mixture comprises methane and between 5% and 60% hydrogen by volume at standard temperature and pressure, and for at least one engine operating condition, maintaining a fuel rail to peak in-cylinder pressure ratio of at least 1.5:

  • 1 when introducing the gaseous fuel mixture into said combustion chamber, and adjusting start of fuel injection timing for said gaseous fuel mixture compared to start of fuel injection timing for natural gas to compensate for an earlier combustion event of said gaseous fuel mixture due to reduced ignition delay.
