Reciprocating internal combustion engine From Wikipedia, the free encyclopedia
Remove ads
Nissan's sidevalve engines were internal combustion automotive engines used in a variety of vehicles. They were based on the Austin 7 engine, with which they shared the 76 mm (2.99 in) stroke. The series began with a 495 cc iteration for the 1930 Datson Type 10 and ended with the 860 cc Type 10 engine that was used until 1964 for light commercial vehicles. Later versions were called the B-1. It was replaced in 1957 by the OHV Nissan C engine that was essentially a de-stroked version of another Austin design, the BMC B-Series.

DAT 495 cc
The displacement of the original version was kept beneath a half litre, since driver's licenses were not required for such cars after a ministerial decision of 1930.[1] The engine was a square design, with a bore and stroke of 54 mm × 54 mm (2.13 in × 2.13 in). Maximum power was 10 PS (7.4 kW) at 3700 rpm.[2]
Applications
- 1930-1931 Datson Type 10
- 1932 Datsun Type 11

DAT 747 cc
For 1933, the rule regarding drivers' licenses was changed so that cars of up to 750 cc could be driven without a license. Accordingly, Datsun enlarged their engine to displace 747 cc (0.7 L; 45.6 cu in) from a bore and stroke of 56 mm × 76 mm (2.20 in × 2.99 in). These dimensions are the same as those of the Austin 7. It produced 12 PS (9 kW) at 3000 rpm, later increased to 14 PS (10 kW).
Applications
- 1933-1934 Datsun Type 12
- 1934-1935 Datsun Type 13/13T

Type 7
This 722 cc (0.7 L; 44.1 cu in) engine is a flat-head side valve automobile engine, a supposedly new design that was slightly smaller but also slightly more powerful than the earlier DAT engine. Bore and stroke were nearly the same as for the earlier version, at 55 mm × 76 mm (2.17 in × 2.99 in). Power is 15 PS (11.0 kW); in 1936 the engine was upgraded to produce 16 PS (11.8 kW). Postwar cars again claimed 15 PS (11.0 kW), at 3600 rpm.[3] In 1950, power was increased again to 20 PS (14.7 kW).

Type 10
Summarize
Perspective
The Datsun Type 10 engine was a 860 cc (0.9 L; 52.5 cu in) engine flat-head side valve automobile engine produced from 1952 through 1964. Bore and stroke were 60 mm × 76 mm (2.36 in × 2.99 in) in the undersquare British style. Later on, the engine's name was shortened to D-10.
Its original output was 20 PS (14.7 kW) for the DC-3, but this increased to 25 PS (18.4 kW) at 4000 rpm and 5.1 kg⋅m (50 N⋅m; 37 lb⋅ft) at 2400 rpm in 1953 thanks to an increased compression ratio of 6.5:1. The engine used a single carburetor. This engine was called the B-1 when installed in the 1958-1964 Datsun Cabstar; this version produces 27 PS (19.9 kW) at 5200 rpm.[4]
