Design, development and variant notes
The source distinguishes the Type 1 and Type 4 engine families. A Type 3 engine is a Type 1 derivative with a lower-profile cooling arrangement, not a separate water-cooled design.
The boxer layout has opposed cylinders and was used in Beetle, Transporter, Type 3 and Type 4 applications, as well as industrial and other vehicles. Individual production periods and specifications vary by displacement and plant.

Further Wikipedia-sourced details
The following additional information is drawn from the cited Wikipedia revision by Wikipedia contributors, available under CC BY-SA 4.0. An open-ended date reflects the source snapshot, not confirmed current production or fitment.
Additional technical and variant notes
The Type 1 engine is described with 112 mm bore spacing and usually an upright cooling shroud with a belt-driven fan. A crank-mounted cooling fan gives the low-profile Type 3 configuration; the Type 4 is a substantially different design.
The source lists the 1,192 cc Type 122 industrial engine at 22.8 kW at 3,000 rpm without a governor, or 21.33 kW with the stated governor setting. It gives 30 kW and 88 N⋅m for a Beetle application; ratings vary by installation.
Type 4 variants are listed at 1.7, 1.8 and 2.0 litres. The source also records industrial and aircraft derivatives, which should not be assumed to share vehicle specifications.
For the 1000 engine, the source lists 1938–1942 KdF-Wagen and 1941–1942 Kübelwagen applications. For the 1100 it lists post-war Beetle and early Type 2 uses; dates and output vary by vehicle and market.

The article traces the Type 1 from the 985 cc KdF-Wagen engine to the 1,600 cc fuel-injected 2003 Mexican Beetle, and identifies a 2006 Brazilian Type 2c as its last Type 1 installation. The Type 3 cooling arrangement is described for 1,500 and 1,600 cc applications.
For the 1,192 cc industrial Type 122, the source lists 81.4 N⋅m at 2,000 rpm without a governor, and 69.63 N⋅m at 2,000 rpm with the stated governor. The Beetle figures are for a different application.
The source describes experimental two-cylinder 'Half VW' aircraft conversions at approximately 22–28 kW. It marks its industrial-engine discontinuation date as needing a citation.
