Honda B engine

From Honda Wiki

Jump to: navigation, search

The B-series Honda inline (I4) DOHC( Dual Overhead Cam ) engines are popular automotive engines from the modern series of Honda engines. From the factory they produce between Convert/hp to around Convert/hp, with even some models having a Redline over 8,900 rpm. The engine has been made in 1.6, 1.7, 1.8, and 2.0 liter variants, with and without VTEC (Variable valve Timing and Electronic lift Control ). Later models have some minor upgrades, for instance modifications to the intake valves and ports and piston tops, along with individual cylinder oil injectors (b18c_ models).
