Chronology
SuccessorStandard Triumph inline-six

The Standard wet liner inline-four engine was an inline four cylinder petrol engine produced by the Standard Motor Company. Originally developed concurrently for passenger car use and for the Ferguson TE20 tractor, it was widely used for Standard passenger cars of the 1950s, most notably the Vanguard. Later it was successfully used in Standard's popular early generation Triumph TR series sports cars.

The water-cooled overhead valve engine featured novel advances for an immediate post-war design, which included thin-wall bearings with replaceable shells and loose-fitted wet liners. Displacement varied from 1,850 cc to 2,088 cc (and 2,188 cc in a tractor variant), growing with time.
