Abstract
To reduce emissions at higher engine loads and speeds, methanol fuel is port-injected with charge-air into a diesel engine, and diesel fuel is then direct-injected to initiate combustion. The charge-air has a reduced oxygen concentration sufficient to prevent pre-ignition of the methanol prior to injection of the diesel fuel, and to reduce NOx formation. At low engine speeds and loads, the engine may run on diesel fuel alone.
