Abstract:
A cylinder liner device comprising:an elongate hollow cylinder having a smooth inner circumferential surface, an outer circumferential surface, and a length;a plurality of longitudinal grooves in the outer circumferential surface extending linearly along the elongate hollow cylinder;a plurality of annular grooves in the outer circumferential surface extending in a circumferential direction along the elongate hollow cylinder; andthe longitudinal grooves intersecting the annular grooves to form a plurality of raised ridges which increase cooling capacity and increase locking ability of the liner within the block;wherein said longitudinal grooves are perpendicular to said annular grooves; andthe plurality of said longitudinal grooves and said annular grooves have equal depths and equal widths; andwherein said longitudinal grooves are spaced equally apart from each other; andwherein said annular grooves are spaced equally apart from each other; anda cylinder block surrounding said elongate hollow cylinder, said cylinder block having an inner surface and an outer surface; andsaid cylinder block inner surface being in direct contact with said ridges of the elongate hollow cylinder, whereby the cylinder liner is locked securely within the cylinder block and the cooling capacity of the device is increased; andwhereby said ridges protrude into and are surrounded by the inner surface of the cylinder block and the cylinder block inner surface protrudes into the longitudinal and annular grooves of the elongate hollow cylinder whereby the ridges, longitudinal grooves, and annular grooves lock the cylinder liner securely within the cylinder block and also increase the area of the cylinder liner outer circumferential surface to provide increased cooling capacity.
