Title:
FUEL PRESSURE SENSOR MOUNTING STRUCTURE, FUEL PRESSURE DETECTION SYSTEM, FUEL INJECTION DEVICE, PRESSURE DETECTION DEVICE USED FOR IT, AND PRESSURE-ACCUMULATION TYPE FUEL INJECTION DEVICE SYSTEM
Document Type and Number:
Japanese Patent JP2009275692
Kind Code:
A
Abstract:

To provide a fuel pressure sensor mounting structure and a fuel pressure detection system capable of suppressing a large size of a fuel injection valve itself in a branch direction by attaining the abolishment of the branching of a high pressure passage toward the fuel pressure sensor inside the fuel injection valve, as a result, capable of enhancing the mounting performance of the fuel injection valve to an internal combustion engine.

A connector 70z is mounted between an injector (fuel injection valve) mounted on the internal combustion engine and injecting fuel from a jet hole and a high pressure pipe 50z for feeding high pressure fuel to the injector. Furthermore, a communication passage 70az for making a fuel flow-in port 43a formed on the injector communicated with a flow-out port 50az of the high pressure pipe 50z is formed inside the connector 70z. Furthermore, the fuel pressure sensor 60z for detecting the pressure of the high pressure fuel circulated in the communication passage 70az is mounted to the connector 70z.
