Design, development and variant notes
The Wasserboxer is a water-cooled, pushrod-operated flat-four petrol engine. Its internal camshaft is gear-driven, and combustion takes place in a bowl in the piston.
Both the 1.9- and 2.1-litre versions use a 94 mm bore; the larger version has a longer stroke. Wikipedia discusses water-jacket sealing and corrosion as possible concerns; the cause of any leak needs inspection.
