Method for facilitating the vaporisation of fuel for a direct injection diesel internal combustion engine

摘要

At the start of intake phase, an intake valve (22) is opened to allow the intake fluid into the combustion chamber (18) and an exhaust valve (26) is opened to feed part of the burnt gas contained in the exhaust pipe into the chamber. Before the end of intake phase, the exhaust valve is closed. At the end of intake phase, the intake valve is closed. During the intake phase, one fuel injection is carried out into the chamber.
