Template:More citations needed Template:Infobox automobile 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)

Inline-4

1H

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 Template:Convert it displaced Template:Convert, power was Template:Convert at 4,400 rpm in 1956, but this increased to Template:Convert in August 1958.[1] 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. [2][3]

Applications:

H

The basic H is a Template:Convert engine produced from 1962 for Nissan's Cedric. Bore and stroke was Template:Convert. The 8.0:1 compression version produced Template:Convert and Template:Convert, while a high-compression engine (8.5:1) produced Template:Convert and Template:Convert.

Applications:

H20

The H20 is the most-common member of the family. Displacing Template:Convert thanks to a larger Template:Convert bore, H20 engines produced around Template:Convert and Template:Convert.

Applications:

Also N230S, T40, forklifts and other machinery

H15

The H15 is an improved, smaller version of the H20-II. It was used in forklifts.

Applications:

  • Nissan J-type forklift (J01M09, J01A15, etc.)

H20-II

The H20-II is an improved version of the H20. It was used in forklifts.

Applications:

  • Nissan J-type forklifts (J02M20, J01A30, etc.)

H20P

The H20P is the LPG-powered version of the H20.

Applications:

H25

The H25 was developed as a high-output version of the H20-II. This engine was used in forklifts.

Template:Convert bore x stroke: Template:Convert.

R (H16)

The R engine used essentially the same block as the H20, but a Template:Convert shorter piston stroke resulted in a capacity reduction of Template:Convert. The R was later named H16. The "R" motor made the switch from 3 to 5 main bearings in 1967 for improved reliability, and the H20 was developed from this arrangement. The R/H16 bore and stroke is Template:Convert displacing Template:Convert. With 9.0:1 compression, the engine produced Template:Convert and Template:Convert.

Applications:

U20

The U20 was similar to the H20 but with an SOHC cylinder head for motorsports applications. Although Prince Motor Company is credited in many sources with designing the U20, it was actually designed in-house at Nissan by Kenichi Sasaki. The U20 was produced in two forms: a stock Template:Convert version with twin SU carburetors, or a Template:Convert version with twin Mikuni/Solex carburetors and a "B" model camshaft.

Applications:

Straight-6

K

The K engine is a Template:Convert straight-6 engine produced from 1963 to 1965. The K engine is an H engine with two extra cylinders. The K engine produces Template:Cvt at 4,400 rpm, Template:Cvt at 2,400 rpm.[5]

Applications:

H30

The H30 is a Template:Convert straight-6 version produced from 1965. Output ranged from Template:Cvt and torque is Template:Convert. The H30 is an H20 with two extra cylinders.

Applications:

This engine is used in large forklifts
