The 2,896 cc, side-valve, four-cylinder engine of the "T" was advanced in its day. It has four cylinders cast as one block. Lubricating oil is propelled around the engine by gravity rather than being circulated by a pump. The pistons are cast-iron. With small valves and a very low compression ratio, output is only 20-22 bhp, and maximum crankshaft speed a mere 1,800 rpm.
