The Nissan P engine is a large overhead valve, inline-six cylinder engine manufactured by Nissan Diesel Motor Co., Ltd. from 1959 to 2003 and used in light-duty trucks by Nissan, as well as in the Nissan Patrol. It replaced Nissan's older, sidevalve engines with which it shared its dimensions.[1] This series of engines were based on the pre-war Type A engine, which was a license built Graham-Paige design.
Introduced in 1950, this is a 3670cc petrol inline six-cylinder engine which produces 750NaN0. This was directly derived from Nissan's pre-war A engine, a license-built Graham-Paige unit.
Applications:
Introduced in 1953, this is a 3670cc petrol inline six-cylinder engine which produces 950NaN0.
Applications:
Introduced in 1955, this is a 3956cc, sidevalve petrol inline six-cylinder which produces 1050NaN0 at 3,400 rpm. Bore and stroke are NaNmm. It was used in various buses and trucks as well as in early Nissan Patrols.[1]
Applications:
The P is a gasoline-powered, overhead valve 3956cc inline six-cylinder[1] with 1250NaN0 at 3,400 rpm initially. Bore and stroke are NaNmm.[1] Later with 1350NaN0, further modifications in 1965 increased the power to 1450NaN0. Later variants were called P40, reflecting the engine displacement in liters (4.0). A variant especially for fire-fighting duties, with a stronger alternator, an engine block heater, and various other improvements, was called the PF engine.
