Abstract
Official abstract text for this publication.
A volume measuring structure for a cylinder block and a cylinder head for an engine includes: a cylinder block configured to form a frame of the 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.
First claim
Opening claim text (preview).
What is claimed is: 1 . A volume measuring structure for a cylinder block and a cylinder head for an engine, comprising: a cylinder block configured to form a frame of the 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 measure a volume of the cylinder head. 2 . The volume measuring structure according to claim 1 , wherein the first pressure sensor is mounted in the cylinder block and is positioned to be close to a flat side of the cylinder head. 3 . The volume measuring structure according to claim 1 , wherein the second pressure sensor is mounted in the ignition plug of the cylinder head and is positioned to be close to a flat side of the cylinder block. 4 . The volume measuring structure according to claim 1 , wherein the first pressure sensor and the second pressure sensor interwork with a controller to reduce volume deviations and compression ratio deviations of the cylinder block and the cylinder head based on the volumes measured by the first pressure sensor and the second pressure sensor. 5 . A volume measuring structure for a cylinder block and a cylinder head for an engine, comprising: a cylinder block configured to form a frame of the 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 and to be positioned to be close to a flat side of the cylinder head to measure a volume of the cylinder block; a second pressure sensor configured to be mounted in the ignition plug of the cylinder head and to be positioned to be close to a flat side of the cylinder block to measure a volume of the cylinder head; and a controller configured to interwork with the first pressure sensor and the second pressure sensor to reduce volume deviations and compression ratio deviations of the cylinder block and the cylinder head based on the volumes determined by the first pressure sensor and the second pressure sensor.
