Hydrogen opposed-piston engine

A two-stroke cycle opposed-piston engine, comprising:

• at least one ported cylinder with a bore;
• a pair of pistons disposed for mutually opposing movements in the bore, such that a maximum volume is defined in the bore when the pistons are furthest apart during a compression stroke of the engine and a minimum volume is defined in the bore when the pistons are closest together during an expansion stroke of the engine;
• an air intake channel configured to convey a flow of charge air to an intake port of the cylinder;
• an exhaust channel configured to receive a flow of exhaust gas through an exhaust port of the cylinder;
• a hydrogen fuel provisioning device configured to provide hydrogen fuel;
• at least one fuel injection device coupled to the hydrogen fuel provisioning device and configured to inject the provided hydrogen fuel into the cylinder bore;
• and,
• a control unit coupled to the at least one fuel injection device and programmed to:
• operate the at least one fuel injection device to cause a pilot injection of hydrogen fuel during an occurrence of a maximum volume defined in the bore between the first and second pistons;
• and,
• operate the at least one fuel injection device to cause a main injection of hydrogen fuel during an occurrence of a minimum volume defined in the bore between the first and second pistons;
• whereby, the hydrogen fuel auto-ignites in response to compression of the charge air in the cylinder.
