Abstract
An engine arrangement of the type including an internal combustion engine having an EGR line, wherein at least one turbine is located on an exhaust line, is provided. The arrangement includes a water vapor generating arrangement using exhaust gases energy to transform liquid water into water vapor. The water vapor is injected in the exhaust line upstream of the turbine. The EGR line is branched off the exhaust line upstream of the turbine and the water vapor generating arrangement includes at least one EGR/water heat exchanger for exchanging heat between the EGR line and the water to be vaporized.
