LIBERTY Diesel Engines are naturally aspirated.  The compact construction, without hampering the accessibility for easy maintenance, results in space economy with an appreciable high power-weight ratio which makes it versatile in all spheres of applications and can offer round-the-clock duty.  The engines share a high degree of inter-changeability of components with those of Lister and Petter engines, which avoids complications of the spares storage/stocks.  Single cylinder construction permits rapid removal of individual cylinder heads, barrels/liners and piston rings.  Both barrel/liner and head are held in position by four steel studs.
