Embodiment Construction

[0022] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0023] Such as figure 1 with figure 2 As shown, the volume measuring structure for a cylinder head and a piston of an engine according to an exemplary embodiment of the present disclosure includes: a piston 101 contained in a cylinder block 100; a cylinder head 200 mounted on the cylinder block 100; a first The pressure sensor 110 is included in the piston 101 ; and the second pressure sensor 210 is included in the cylinder head 200 .

[0024] The cylinder block 100 forms the frame of the engine.

[0025] A cylinder is provided inside the cylinder block 100, and a piston 101 is provided inside the cylinder to generate power.

[0026] Such as figure 1 As shown, the piston 101 is provided with a first pressure sensor 101 to measure the pressure inside the piston 101 in order to determine the volume of the piston 101 .

[0027] In addition, th...

Abstract

A volume measuring structure of a cylinder head and a piston for an engine includes: a cylinder block configured to form a frame of an engine and include a cylinder in which a piston reciprocates to generate power; a cylinder head configured to be mounted on the cylinder block to form a combustion chamber along with the cylinder and include an ignition plug which ignites the engine and a valve which opens and closes intake and exhaust passages; a first pressure sensor configured to be mounted in the cylinder block to determine a volume of the cylinder block; and a second pressure sensor configured to be mounted in the cylinder head to determine a volume of the cylinder head.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the benefit of priority from Korean Patent Application No. 10-2015-0086448 filed with the Korean Intellectual Property Office on June 18, 2015, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The present disclosure relates to a volume measuring structure for a cylinder head and a piston of an engine, and more particularly, to a volume measuring structure for a cylinder head and a piston for an engine capable of measuring the volumes of the piston and the cylinder head At the same time, the pressure sensor is used to improve the accuracy of volume measurement and reduce volume deviation and compression ratio deviation. Background technique [0004] In general, the compression ratio of an engine is an important variable for determining the overall engine efficiency at compression relative to the volume of the combustion chamber. [0005...
