The Hyundai Beta engines are 1.6 L to 2.0 L I4 built in Ulsan, South Korea. All Beta engines are dual overhead camshaft valvetrain (DOHC) design. The Beta engine uses a direct-acting overhead cam valvetrain arrangement which places the camshaft in the cylinder head above the pistons and combustion chamber and operates the valve tappets/lifters directly. The Beta engine's ignition system is designed to ignite the fuel/air charge that enters each cylinder by producing a high voltage spark at the exact moment for maximum efficiency. All Beta versions are equipped with a Distributorless Ignition System (DIS). The system consists of the ignition coil assembly, Camshaft Position Sensor (CMP), Powertrain Control Module (PCM), spark plug wires and spark plugs. The Beta engine family includes the following engine codes: G4GR, G4GB, G4GC, G4GF and G4GM.
