GENERAL DESCRIPTION
Cylinder Head Gasket
The cylinder head gasket is laminated steel sheets.
Three grades of the gasket according to the measured
piston head projection from the cylinder block are
provided to give the engine a minimum compression
ratio fluctuation.
Tightening Method for
Special Bolt
The cylinder head fixing bolts, flywheel bolts and
connecting rod cap fixing bolts are tightened by the
angular Tightening Method.
Piston
Auto-thermatic pistons having steel struts with a 0.4
mm offset from the piston pin center line, are applied to
reduce thermal expansion and resulting engine noise
when the engine is cold.
Bearings
The crankshaft bearings and connecting rod bearings
are of aluminum having a high bearing surface.
These bearings are especially sensitive to foreign
material such as metal scraps. So, it is very important
that the oil ports and other related surfaces are kept
clean and free of foreign material.
Crankshaft bearings are selected for optimum bearing
and journal clearance which reduces vebration and
noise.
Crankshaft
As tufftriding (Nitrizing treatment) is applied to increase
crankshaft strength, crankpins and journals should not
be reground.
Piston Cooling
An oiling jet device for piston cooling is provided in the
lubricating oil circuit from the cylinder block oil gallery
via a check valve.
Take care not to damage any oiling jet when removing
and installing piston and connecting assembly.
Fuel Injection System
The injection system is oil rail type.
Quick On Start 4 System
QOS4 preheating system which features a quick-on
glow plug with thermometer control of the glowing time
and the afterglow time function, is applied.
