Description
Honda L15A Engine
Depending on the specific version, the L15A uses SOHC 16-valve VTEC or i-VTEC technology, electronic fuel injection, and a chain-driven camshaft. Honda describes VTEC as a system that changes valve operation according to engine speed to improve low-speed torque and high-speed power.
The L15A was used in vehicles including the Honda Fit/Jazz, City, Airwave, Mobilio, Freed, and related models, with output varying according to the particular engine version and vehicle application.
