The '''B-series''' are a family of inline four-cylinder DOHC automotive engines introduced by [[Honda]] in 1988. Sold concurrently with the [[Honda D engine|D-series]] which were primarily SOHC engines designed for more economical applications, the B-series were a performance option featuring dual overhead cams along with the first application of Honda's [[VTEC]] system (available in some models), high-pressure die cast aluminum block, cast-in quadruple-Siamese iron liners.<ref>{{Cite web |title=AE: Honda's Siamese-quadruplet cylinder liner casting |url=https://dwolsten.tripod.com/articles/jan96a.html |access-date=2023-04-12 |website=dwolsten.tripod.com |archive-date=2023-04-12 |archive-url=https://web.archive.org/web/20230412210343/https://dwolsten.tripod.com/articles/jan96a.html |url-status=live }}</ref>

To identify a Honda B-series engine, the letter B is normally followed by two numbers to designate the displacement of the engine, another letter, and in US-spec engines, another number. The Japanese spec-engines are normally designated with a four character alphanumeric designation.<ref>{{cite book|last=Jason|first=Siu|title=Honda B-series engines|year=2008|location=39966 grand ave North Branch MN,55056|isbn=978-1-932494-78-5|pages=6}}</ref> The B-series, the B20B variant in particular, is not to be confused with the earlier [[Honda B20A engine]] introduced in 1985 and primarily available in the Prelude and Accord-derived vehicles from 1985 to 1991. While sharing some design elements and both being multivalve Honda four-cylinders, the B-series and B20A differ substantially in architecture, enough to be considered distinct engine families.<ref>{{Cite web |last=CarTechBooks |title=An Introduction to the Honda B-Series Engine |url=https://www.cartechbooks.com/blogs/techtips/introductiontohondabseriesengines |access-date=2023-12-03 |website=CarTechBooks |archive-date=2023-10-02 |archive-url=https://web.archive.org/web/20231002112140/https://www.cartechbooks.com/blogs/techtips/introductiontohondabseriesengines |url-status=live }}</ref>

They were made in {{convert|1595|cc|L|1|abbr=on|order=flip}}, {{convert|1678|cc|L|1|abbr=on|order=flip}}, {{convert|1797|cc|L|1|abbr=on|order=flip}}, {{convert|1834|cc|L|1|abbr=on|order=flip}}, and {{convert|1973|cc|L|1|order=flip}} variants, with and without VTEC ([[VTEC|Variable Valve Timing and Lift Electronic Control]]). Later models have minor upgrades including modifications to the intake valves and ports and piston tops, along with individual cylinder oil injectors (B18C models). They produce between {{convert|126|hp|kW PS|0|abbr=on}} and {{convert|197|hp|kW PS|0|abbr=on}}, with some models capable of a [[redline]] of 8400 RPM.<ref>{{Cite web |last=CarTechBooks |title=An Introduction to the Honda B-Series Engine |url=https://www.cartechbooks.com/blogs/techtips/introductiontohondabseriesengines |access-date=2023-11-30 |website=CarTechBooks |archive-date=2023-10-02 |archive-url=https://web.archive.org/web/20231002112140/https://www.cartechbooks.com/blogs/techtips/introductiontohondabseriesengines |url-status=live }}</ref>

Although it has many variations, the basic design differs very little among the B-Series. There are actually two short blocks which are used for the entire series. The distinction between them was the cylinder block deck height. The one used for B16 and B17 engines (except for B16B) has a deck height of {{convert|203.9|mm|abbr=on}} while the short block used for B16B, B18 and B20 engines has a deck height of {{convert|212|mm|abbr=on}}.<ref>{{cite web|url=http://www.jdmspecengines.com/honda-engines/b-series.html|archive-url=https://web.archive.org/web/20090622172911/http://www.jdmspecengines.com/honda-engines/b-series.html|url-status=usurped|archive-date=June 22, 2009|title=JDM Spec Engines - Honda B-Series Engines|work=jdmspecengines.com}}</ref>

The Honda B16 has appeared in six different forms over the years. 
The Honda B-series was replaced by the [[Honda K engine|K-series]] in Civic, Integra, Odyssey, and CR-V applications.
