LD00001 is a component of the Teledyne W-4, a family of four-cylinder, liquid-cooled, horizontally-opposed engines. The component is a high-performance cylinder head designed to increase the power output of the engine. The cylinder head is made of cast aluminium alloy, and features a lightweight configuration that results in improved thermal efficiency. It also features four valves per cylinder, as well as a direct-injection fuel system and an integrated exhaust-gas recirculation system. The cylinder head also features sodium-filled exhaust valves, which are designed to reduce exhaust temperatures and increase power output.
