三菱・4G4系エンジン Mitsubishi Neptune engine
rdfs:comment
The Mitsubishi Neptune or 4G4 engine is a series of iron-block OHV inline-four engines built by Mitsubishi Motors from 1971 to 1979, alongside the Orion, Saturn, Astron, and Sirius. This was to be Mitsubishi's last OHV engine. The inability to clear new passenger car emissions rules for 1978 meant that the Neptunes were replaced by the 4G1 Orion. The Neptune continued to be built until 1979 for commercial vehicles, which suffered less restrictive environmental regulations. 三菱・4G4系エンジン（みつびし・4G4けい-）は1971年から1979年まで三菱自動車工業によって製造されていた1.2L - 1.4Lの小排気量車、および産業用の直列4気筒ガソリンエンジン。通称ネプチューンエンジン。バルブ駆動方式はすべてOHVを採用していた。しかし、昭和54年排出ガス規制をクリアすることができず、結果的にSOHCヘッドを用いた小型・軽量設計の4G1系エンジン（通称オリオンエンジン。のちにDOHCヘッドも追加される）に取って代わられた。なお、本項では自動車用に限り記述する。
