Injection system for internal-combustion engine of motor vehicle, has common rail, multiple injectors and fuel high-pressure pump for impingement of common rail with fuel stands under high pressure

摘要

#CMT# #/CMT# The injection system has a common rail, multiple injectors, a fuel high-pressure pump for impingement of the common rail with highly pressurized fuel and a fuel conveying pump (3) for supplying of fuel for the fuel high-pressure pump. A venturi nozzle (5) is integrated in the fuel conveying pump or its internal cycle. #CMT#USE : #/CMT# Injection system for an internal-combustion engine of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The injection system has a common rail, multiple injectors and a fuel high-pressure pump for impingement of the common rail with fuel stands under high pressure, where a venturi nozzle is integrated in the fuel conveying pump or its internal cycle, and hence ensures a reliable injection system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic partial view of an injection system. 1 : Conveying pump unit 2 : Fuel tank 3 : Fuel conveying pump 4 : Return line 5 : Venturi nozzle.
