Forming fuel-air mixture for internal combustion engine during hot start phase involves storing easily boiling components of fuel during normal operation and using for hot starting

摘要

The method involves evaporating fuel during normal engine operation to extract easily boiling components of the fuel used in normal operation. The extracted components are condensed and collected as a cold starting fuel in a reservoir tank (27) then fed to the engine (22) for hot starting. The fuel delivery arrangement has an evaporation and condensing system (15). Independent claims are also included for the following: a fuel delivery arrangement.
