A Caterpillar 3304 diesel engine has been converted to a turbocharged, aftercooled, spark ignition, hydrogen engine. The objective of the conversion was an ultra-low emission power system for underground mining vehicles. Performance and NOx-emission data are presented which indicate that power and fuel consumption are comparable to naturally-aspirated diesels while exhaust emissions are very low. Brake-specific NOx emissions (the only significant pollutant with hydrogen fuel) have been held to less than 0.7 gram per kilowatt-hour. The fuel control system is a low-pressure form of intake port injection termed ''Parallel Induction.'' The attributes of this fluidic control system are simplicity, ruggedness and ease of maintenance, all of which are essential for underground mining equipment.
