Abstract
An in-cylinder pressure detecting apparatus for detecting a pressure in a combustion chamber of an internal combustion engine is provided. The in-cylinder pressure detecting apparatus comprises a pressure detecting element mounted on a tip-portion of a fuel injection device which injects fuel into the combustion chamber, and an amplifying circuit unit having an amplifying circuit which amplifies a signal output from the pressure detecting element and outputs a pressure detection signal. An in-cylinder pressure detecting unit integrated fuel injection device is configured by integrating an in-cylinder pressure detecting unit with the fuel injection device. The in-cylinder pressure detecting unit includes the pressure detecting element, the amplifying circuit unit, and a connecting member connecting the pressure detecting element with the amplifying circuit unit. The in-cylinder pressure detecting unit integrated fuel injection device is mounted on the internal combustion engine.
