Abstract

Each cylinder (1) of the piston engine is provided with a first fuel injector (4), which is configured for injecting liquid alcohol into the cylinder (1), with a second fuel injector (5), which is configured for injecting liquid hydrocarbonaceous fuel into the cylinder (1), and with means (7, 14) for heating air/fuel mixture in the cylinder (1) for aiding the ignition of the liquid alcohol.
