Purpose, Function<\/p>\n


<\/p>\n

<\/a><\/p>\n

Piston<\/p>\n

\n
\n
\u2022 The piston in the cylinder of the cylinder block moves reciprocally by the pressure received when the air-fuel mixture combusts.<\/div>\n<\/dd>\n<\/dl>\n


<\/p>\n

<\/a><\/p>\n

Piston ring<\/p>\n

\n
\n
\u2022 The piston ring consists of the compression ring (top ring, second ring) and the oil ring, and has the following functions.<\/div>\n
\n
\n
\u2015 The compression ring prevents leakage of pressure in the cylinder from the piston circumference.<\/div>\n
\u2015 The oil ring clears off extra engine oil adhered to the cylinder wall.<\/div>\n<\/dd>\n<\/dl>\n
\u2022 The piston ring transmits piston heat to the cylinder wall to cool the piston.<\/div>\n<\/dd>\n<\/dl>\n


<\/p>\n

<\/a><\/p>\n

Piston pin<\/p>\n

\n
\n
\u2022 The reciprocating movement of the piston is transmitted to the connecting rod by the connection of the piston pin to connecting rod.<\/div>\n<\/dd>\n<\/dl>\n

Construction<\/p>\n


<\/p>\n

<\/a><\/p>\n

Piston<\/p>\n

\n
\n
\u2022 The high-temperature strength piston is made of aluminum alloy with excellent thermal conductivity.<\/div>\n
\u2022 The piston has a cavity on the top surface. As a result, the initial combustion flame is prevented from hitting the top surface of the piston to reduce cooling loss.<\/p>\n\n\n\n

\n
\n
\u2022 The sliding resistance and the part mass have been reduced by reducing the surface area of the piston skirt and thinning the thickness.<\/div>\n
\u2022 An offset piston has been adopted in which the center of the piston pin has been offset from the piston center. As a result, piston slap is suppressed.<\/p>\n\n\n\n

<\/p>\n

<\/a><\/p>\n

Piston ring<\/p>\n

\n
\n
\u2022 A barrel-face ring for the top ring and a taper under cut ring for the second ring have been adopted.<\/div>\n
\u2022 A three-piece oil ring consisting of a side rail and spacer have been adopted for the oil ring.<\/div>\n
\u2022 Tracking capability to the cylinder wall has been improved by thinning down the piston ring. As a result, a low-tension piston ring has been implemented without increasing the engine oil consumption, and the sliding resistance has been reduced during reciprocating movement.<\/div>\n<\/dd>\n<\/dl>\n


<\/p>\n

<\/a><\/p>\n

Piston pin<\/p>\n

\n
\n
\u2022 The piston is a full-floating type.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n
