The Neptune (or 4G4x) family of engines were a family of inline 4 cylinder engines featuring cast iron blocks, alloy heads and are of a overhead valve (pushrod) design. They were produced from 1971 through 1979.

The Neptune family replaced the JH4 which Mitsubishi had been building under licence from Willy's. The engine was shortlived, with it unable to meet increasingly tougher emissions regulations in the 1970s, leading to it being replaced by the Orion.
