Should the 474 Engine Camshaft Pulley Align with E or I?

[StAdriana]

474 engine camshaft pulley aligns with E. Its inner diameter has two grooves, fitting onto a small protrusion on the camshaft. In factory vehicles, the E point of the camshaft pulley inner diameter is locked onto the camshaft. An engine is a machine capable of converting one form of energy into another, typically transforming chemical energy into mechanical energy. Engines are classified into: 1. Gasoline engines; 2. Diesel engines. An engine consists of a crank-connecting rod mechanism, valve train, fuel supply system, cooling system, lubrication system, ignition system, and starting system. It is categorized into piston engines, ramjet engines, rocket engines, and turbine engines.
