American diesel aircraft engine
The DH180 is V-4 piston
diesel aircraft engine developed for aircraft applications by
DeltaHawk of
Racine, Wisconsin. The engine was
type certified on April 7, 2023.
[1]
The design is a four-cylinder, two-stroke, piston
diesel engine, in an inverted-V configuration, with
turbocharging and
supercharging, mechanical
fuel injection, liquid cooling, direct drive. It can run on
Jet-A or
sustainable aviation fuel. The manufacturer claims that it has "40 percent fewer moving parts than other engines in its category."

In 2014, a DH180 was installed and demonstrated at the
EAA Airventure airshow on a
Cirrus SR20. A retrofit kit is planned for the SR20.

The engine received its
type certificate from the
Federal Aviation Administration on April 7, 2023, with first customer deliveries planned for 2024.
