The Hatz 1D90E is designed for tough industrial duty where you want high single-cylinder output in a compact, service-friendly package — with the added benefit of electronic fuel control. The air-cooled layout keeps installation straightforward and reduces cooling-system complexity, while the electronically controlled injection system supports stable operation and integration into modern equipment packages.

With 0.667L displacement and electronic direct injection, the 1D90E produces up to 11.0 kW (15.0 hp) at 3000 rpm and 10.0 kW (13.6 hp) at 3600 rpm for variable-speed operation. For constant-speed duties, it’s rated at 10.0 kW (13.6 hp) at 3000 rpm, with additional constant-speed points shown at 7.3 kW (9.9 hp) at 1800 rpm and 6.1 kW (8.3 hp) at 1500 rpm — useful where stable governed-speed output is required.
