中島護發動機(日语:まもりエンジン)乃日本中島飛機公司研發製造的氣冷式星型飛機用活塞發動機,採複列14汽缸、底置凸輪軸(over head valve,縮寫成OHV)、離心式機械增壓的配置},中島內部代號為「NK7」;大日本帝國陸軍和大日本帝國海軍共同命名成Ha-103(日语:ハ103)。 另外,中島飛機團隊在開發新引擎——18汽缸的「超級護引擎」(海軍編號為NK10;陸軍編號為Ha-217;海軍和陸軍共同編號為Ha-46)時,仍然大量沿用護發動機的既有設計經驗,包括汽缸尺寸、排氣管等散熱配置、火星塞位置等,因此兩者相當雷同。

The Nakajima Mamoru (護, Preserve) engine was a 14-cylinder, air-cooled, two-row radial engine of 1870 hp. At some 44.9 litres (2,740 in²) displacement, it was one of the largest-displacement 14-cylinder radial engines in the world, rivalling the similar configuration Allies' American Wright Twin Cyclone engine of 42.7 litre (2,600 in²) and Soviet Shvetsov ASh-82 engine of 41.2 litre (2,515 in²) displacement levels, and was meant to compete with early 18-cyl engines. The Nakajima model designation for this engine was NAK while it was an experimental project, in service it was known as the NK7, and known as the Ha-103 by the Army and "Mamori" or "Mamoru" by the Navy. According to unified designation code it was Ha-36.The meanings of these two Japanese words are very similar, Mamori translate

According to unified designation code it was Ha-36.The meanings of these two Japanese words are very similar, Mamori translates as protection and Mamoru, translates as to guard, protect, defend and obey. The competitor of successful Mitsubishi Kasei engine, the Mamoru proved to be unreliable and was rarely able to operate near its design power. Designs based on the Mamoru were forced to use other engines, typically the less powerful Mitsubishi Kasei or the Nakajima Homare. Production of the Mamoru was ended by the Navy after only a few hundred production examples were built.
