Valve timing mechanism of the engine

Cylinder head

Location of I and E marks when installing timing sprockets

The inline 4-cylinder, 4-stroke gasoline water-cooled engine is equipped with

two camshafts located in the cylinder head. 16.

valves (4 per cylinder) are arranged in a V-configuration. The camshaft drive

is driven from the crankshaft by a timing belt. One of the two camshafts actuates the intake valves, and the other camshaft actuates the exhaust valves. In the

valve drive, hydraulic lash adjusters are installed..

The cylinder block is cast from aluminum alloy and has four cylinders in a row. Cast iron cylinder liners are installed in the cylinder bores..

The cast aluminum alloy cylinder head is of cross-flow design.

Lash adjusters are installed in the valve drive of each

valve.

The forged steel crankshaft is supported by five main bearings with insert bearing shells. Crankpins are located in one plane at 180 degrees. The cast iron camshaft is installed on five bearings in the aluminum

housing located on top of the cylinder head. Rotation of the camshaft

is transmitted from the crankshaft by a timing belt and sprocket,

installed on the front end of the camshaft..

The sprockets installed on both camshafts have identical shape and are marked with letters I and E (respectively for the shaft controlling the

intake valves, and for the shaft controlling the exhaust valves)..

Warning.

New camshafts installed on the intake and exhaust

valves are interchangeable. However, used camshafts are not

interchangeable..

Pistons are made of aluminum alloy. Each piston has two

compression rings and one oil control ring. To reduce piston pressure on the cylinder wall during the power stroke, the piston pin axes are offset 0.35–1.65 mm from the piston axis..

The piston pin fit in the piston is a floating (clearance) fit, and in the

connecting rod small end it is an interference fit..

The valves are actuated directly by the camshaft lobes..

Hydraulic lash adjusters installed in the valve lifters help reduce engine noise. The valve train design withstands severe operating conditions at high engine speeds and reduces the labor required for valve train maintenance.
