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 66 PS (49 kW) in the Logo to 140 PS (103 kW) 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.
