1) Cylinder

(1) Compression pressure test

Specified value

▶

Compression ratio

16.5 : 1

Test condition

at normal operating temperature (80˚C)

Compression pressure

Standard

32 bar

Minimum

18 bar

Differential limit between cylinders

Maximum 3 bar

The compression pressure test is to check the conditions of internal components (piston, piston ring,

intake and exhaust vale, cylinder head gasket). This test provides current engine operating status.

Before cranking the engine, make sure that the test wiring, tools and persons are keeping away from

moving components of engine (e.g., belt and cooling fan).
