General data of the CVH engine (Escort 4)

The CVH engine (C – Compound, V – Valve angle, H – Hemispherical chamber) has a V-shaped arrangement of valves. The camshaft, mounted on five bearings in the cylinder head made of light alloy, is driven by a toothed belt from the crankshaft and controls the valves through levers and hydraulic tappets.

The camshaft bearings are not designed to be replaced, so if they wear out, the cylinder head must be replaced. The fuel pump is mounted on the cylinder head and is driven by a pusher from the camshaft eccentric.

The use of hydraulic tappets does not require adjustment of the valve clearance. During long periods of engine downtime or after repair of the cylinder head on a cold engine, valve knocking may occur, which is considered normal and disappears as the hydraulic tappets are filled with engine oil from the engine lubrication system.

The crankshaft is mounted on five bearings and balanced by counterweights.

The gear oil pump is located at the front of the engine cylinder block and is driven directly by the crankshaft.
