燃烧压力检测装置、带燃烧压力检测装置的内燃机
摘要：
一种燃烧压力检测装置，该燃烧压力检测装置用于检测内燃机的燃烧室内的燃烧压力，其特征在于：燃烧压力检测装置能够安装于将构成燃烧室的汽缸头(4)的内部与外部连通的连通孔(4a)，燃烧压力检测装置具有壳体(30)和在壳体(30)内检测燃烧压力的压电元件等，壳体(30)具有能够向连通孔(4a)安装的安装构造部，安装构造部具有能够供第1密封构件(71)安装的第3外周面(333)、能够供第2密封构件(72)安装的倾斜面(315a)，在燃烧压力检测装置安装于连通孔(4a)时，倾斜面(315a)配置在比第3外周面(333)靠燃烧室方向的顶端侧。
摘要（英）：

A combustion pressure detection device for detecting the combustion pressure in a combustion chamber of an internal combustion engine, characterized in that: the combustion pressure detection device can be mounted to a communication hole (4a) so that an inner portion and an outer portion of a cylinder head (4), which forms the combustion chamber, are in communication; the combustion pressure detection device includes a housing (30), and a piezoelectric element that detects the combustion pressure in the housing (30); the housing (30) includes a mounting structure portion that can be mounted to the communication hole (4a); the mounting structure portion includes a third outer circumferential surface (333) to which a first seal member (71) can be mounted, and an inclined surface (315a) to which a second seal member (72) can be mounted; and when the combustion pressure detection device is mounted to the communication hole (4a), the inclined surface (315a) is disposed further toward the tip end side in the direction of the combustion chamber than the third outer circumferential surface (333).
