TheL-series is a compactinline-four engine created byHonda, introduced in 2001 with theHonda Fit. It has 1.2 L (1,198 cc), 1.3 L (1,318 cc) and 1.5 litres (1,497 cc) displacement variants, which utilize the names L12A, L13A and L15A. Depending on the region, these engines are sold throughout the world in the 5-doorHonda BrioFit/JazzhatchbackHonda Civic and the 4-doorFit Aria/Citysedan (also known as Fit Saloon). They can also be found in theJapanese-onlyAirwavewagon andMobilioMPV.

Two different valvetrains are present on this engine series. The L12A, L13A and L15A use (Japanese:i-DSI), or “intelligent Dual & Sequential Ignition”. i-DSI utilizestwo spark plugs per cylinder which fire at different intervals during the combustion process to achieve a more complete burn of the gasoline. This process allows the engine to have more power while keepingfuel consumption low, thanks to the better gasoline utilization. Emissions are also reduced. The i-DSI engines have two to fivevalves per cylinder and a modest redline of only 6,000 rpm, but reach maximum torque at mid-range rpm, allowing for better performance without having to rev the engine at high speeds. The i-DSI is also known for not using Turbochargers in the performance category, as it uses a high compression, long stroke with a lightweight and compact engine.

The other valvetrain in use is theVTEC on one of the two varieties of the L15A. This engine is aimed more at performance than efficiency with a slightly higher redline with4 valves per cylinder, which reaches peak torque at higher rpm. However, it still offers a good combination of both performance andfuel efficiency. Both the i-DSI and VTEC have relatively high compression ratios at 10.8:1 and 10.4:1, respectively.

Before April 2006, the L-series were exclusively available with a 5-speedmanual transmission,continuously variable transmission (CVT) anddual clutch transmission (DCT). With the introduction of the Fit in Canada and the United States, an L-series engine was mated to a traditionalautomatic transmission with atorque converter for the first time. The L12A i-DSI is available exclusively in theEuropean domestic market Jazz and is sold with only a 5-speed manual transmission.

As of 2010, the L15A7 (i-VTEC) is a class legal engine choice forSCCA sanctionedFormula F competition, joining the 1.6LFord Kent engine.^[1]

In 2016 Honda introduced the L15B (DOHC-VTC-TURBO-VTEC) engine as part of their continuing global earth dreams strategy for lower emissions and higher fuel economy for a range of their cars, available with 6-speed manual and CVT transmissions withEarth Dreams Technology.^[2]
