The Mitsubishi 4G9 engine is a series of straight-4 automobile engines produced by Mitsubishi Motors. All are 16-valve, and use both single- and double- overhead camshaft heads. Some feature MIVEC variable valve timing, and it was the first modern gasoline direct injection engine upon its introduction in August 1996.
