An internal combustion engine with charge stratification and directed air flow is provided. A charge motion control valve is positioned in the upper intake manifold and bifurcated intake ports are utilized in the cylinder head which direct the air flow into one intake port when desired. This provides improved engine performance, emissions, and fuel economy with easier packaging and consequently reduced cost.

A reciprocating internal combustion engine uses intake valve seats which are offset from the intake port center lines such that charge motion of the inlet charge will be increased without the need for a charge motion control valve, and without causing a loss of volumetric efficiency of the engine.

A camshaft lash adjustment process for an internal combustion engine includes the steps of substituting a tiltable camshaft retainer for a camshaft bearing cap which is proximate a driven end of the camshaft, followed by removal of all remaining camshaft bearing caps and the substitution of a camshaft tilt limiter for one of the camshaft bearing caps so as to allow rotation of the camshaft to a tilted position. This permits adjustment of valve tappets driven by the camshaft.

An automotive type engine valvetrain rocker arm is constructed with a hydraulic lash adjusting assembly, with the mass of the adjusting assembly being closely adjacent the pivot axis of the rocker arm to minimize the rotational moment of inertia of the rocker arm.
