Nissan H engine

The Nissan H series of automobile engines is an evolution of the Nissan "R" engine which was based on the 1.5-liter, three-main bearing "G" engine used in the 1960s. Both inline-four and inline-six versions were produced. It is a pushrod OHV design with iron block, early models with an iron head, later models with aluminum head. Versions of this motor have been used in many Nissan autos and forklifts, well into the eighties and a version called H20II was in production until 2003. The SD diesels are based on this series of motors (bore spacing and basic block layout)

The 1H is not related to the later H engines. It was also an all-iron, OHV engine, but this was a licensed BMC (Austin) B engine. With a bore and stroke of 73 mm × 89 mm (2.87 in × 3.50 in) it displaced 1.5 L (1,489 cc), power was 50 PS (37 kW; 49 hp) at 4,400 rpm in 1956, but this increased to 57 PS (42 kW; 56 hp) in August 1958. The license agreement terminated in the late 1950s and the Nissan G engine was a more compact replacement, which in turn became replaced by the (below) Nissan H engines. The 1H would also be de-stroked from 89mm to 59mm to become the 1.0 L (990 cc) to create the Nissan C engine at the suggestion of former Willys-Overland engineer Donald Stone.

Applications:

The basic H is a 1.9 L (1,883 cc) engine produced from 1962 for Nissan's Cedric. Bore and stroke was 85 mm × 83 mm (3.35 in × 3.27 in). The 8.0:1 compression version produced 92 hp (69 kW; 93 PS) and 159 N⋅m (117 lb⋅ft), while a high-compression engine (8.5:1) produced 95 hp (71 kW; 96 PS) and 163 N⋅m (120 lb⋅ft).

Applications:

The H20 is the most-common member of the family. Displacing 2.0 L (1,982 cc) thanks to a larger 87.2 mm (3.43 in) bore, H20 engines produced around 99 hp (74 kW; 100 PS) and 167 N⋅m (123 lb⋅ft).

Applications:

Also N230S, T40, forklifts and other machinery
