FEATURES Engine mechanical (piston, piston pin and piston ring) Structure Piston and piston pin • The heat-resistant aluminum alloy is used for the piston. The specially shaped combustion chamber is adopted in order to realize excellent combustion and fuel-efficiency. • The outer shape of the piston is optimally profiled with taking a thermal expansion and piston oscillations into account.
Page 32
Engine mechanical (connecting rod and crank shaft) Structure Connecting rod • The connecting rod is made of forged carbon steel. Its large end is horizontally split, which has advantages in rigidity. The bush made of lead bronze with the oil groove in the center is pressed in its small end.
Page 33
Cam shaft • The camshaft is manufactured by knockdown system. The cam lobe and the com journal are pressed in a hollow carbon steel tube. The cam lobe is welded. • By adopting a special profile for the cam, together with improving inhalation efficiency, quiet operation can be expected.

EGR valve • To correspond to the automobile exhaust gas regulations of 2005, the computerized double-seated valve linear solenoid type of EGR valve was adopted. • The computerized double-seated valve linear solenoid type of EGR valve was adopted in order to improve accuracy in adjustment and to reduce particulates and Nox altogether.
Page 36
Structure • The flame-proof resin that is light and oil resistant is used for the main body of the closed ventilator. For the oil separate part, element-less type, which is maintenance-free, is adopted. • To separate the oil mist in the blowby gas, there is a slewing part for the centrifugation and a filtering part for crash and separation inside.
LUBRICATION SYSTEM SPECIFICATION Lubrication method Pressure lubrication by gear pump Oil filters Paper filters for both full flow and bypass Lubricating oil cooler Water cooled multi plate type GENERAL DESCRIPTION • Oil in the oil pan is drawn up through a strainer by the oil pump housed at the rear end of the cylinder block and then lead into the oil cooler where it exchanges heat with cooling water.
