Sequence X Test (ASTM Draft)

Engine

The Sequence X Test utilizes a 2012 Ford 2.0 liter, spark ignition, four stroke, 4-cylinder gasoline turbocharged direct injection (GTDI) engine. Features of this engine include variable camshaft timing, dual overhead camshafts driven by a timing chain, four valves per cylinder and electronic direct fuel injection.

Test Operation

The Sequence X Test evaluates undesirable timing chain wear in gasoline, turbocharged, direct-injection (GTGI) engines. The test has demonstrated a correlation to observed timing chain wear in the field and provides a means for evaluating the performance of fully formulated engine lubricating oils. The laboratory engine test consists of two stages and runs for a total of 216 hours. The increase in timing chain length determined at the end of test is the primary result.
