#CMT# #/CMT# The accumulator has a high-pressure container (11) provided with a fuel inlet (12). An outer latent heat storage unit (10) is fitted on the high-pressure container on an outer side. An inner latent heat storage unit (10) is fitted on an inner side of the container. The outer latent heat storage unit exhibits a phase charge material layer (16) that is embedded between a wall (111) of the container and a casing (17). A salt granule e.g. Glauber salt and sodium acetate, an organic compound such as paraffin and fatty acid, and a paraffin-like heptadecane, are used as the phase charge material. #CMT#USE : #/CMT# High pressure fuel accumulator for a fuel injection system of an internal combustion engine of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The provision of the outer and inner latent heat storage units reduces the cooling of the high-pressure container and the fuel volume in the high-pressure container, thus slowing-down the fuel cooling during a season so that a longer parking time is provided for the motor vehicle according and negative characteristics like longer starting time, higher fuel enrichment in the internal combustion engine and the emission of unburned hydrocarbons with increased fuel consumption during the cold start are avoided. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a high pressure fuel accumulator with a latent heat storage unit for a fuel injection system of an internal combustion engine. 10 : Outer and inner latent heat storage units 11 : High-pressure container 12 : Fuel inlet 16 : Phase charge material layer 17 : Casing 111 : Wall. |
