The Honda D-series inline-four cylinder engine is used in a variety of compact models, most commonly the Honda Civic, CRX, Logo, Stream, and first-generation Integra. Engine displacement ranges between 1.2 and 1.7 liters. The D series engine is either SOHC or DOHC, and might include VTEC variable valve lift. Power ranges from in the Logo to in the Japanese market (JDM) Civic. D-series production commenced in 1983 (for the 1984 model year) and ended in 2005. D-series engine technology culminated with production of the D15B three-stage VTEC (D15Z7) which was available in markets outside of the United States. Earlier versions of this engine also used a single port fuel delivery system called PGM-CARB, signifying that the carburetor was computer controlled.
