Chevrolet Small GAS Engine 14L LUW specs: 85 ci (1.4L) 4-cylinder, 2.913 x 3.201 in (74 x 81.3 mm) bore and stroke, 10:1 compression. Rated 153 hp. DOHC.
The Chevrolet Small GAS Engine 14L LUW is undersquare — the 3.2008" stroke exceeds the 2.9134" bore by 9.0% — a layout that trades peak RPM for leverage and torque low in the range. The 3.2008" stroke does not reach 4,000 ft/min of mean piston speed until about 7,500 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 4 cylinders displaces 21.3 ci (348 cc).
10:1 on aluminum heads is in the range that usually runs on pump premium; aluminum sheds heat faster than iron, which makes the same number a little more forgiving.
It is one of 20 engines in the Ecotec family, sitting between the 61 ci and 150 ci members. Factory fitments include the Chevrolet Cruze, Chevrolet Malibu, Chevrolet Trax and 1 other.
