Chevrolet LUZ specs: 119 ci (2.0L) 4-cylinder, 3.268 x 3.559 in (83 x 90.4 mm) bore and stroke, 16.5:1 compression. Rated 151 hp, 2014–2015.
The Chevrolet 119ci (LUZ) is undersquare — the 3.5591" stroke exceeds the 3.2677" bore by 8.2% — a layout that trades peak RPM for leverage and torque low in the range. The 3.5591" stroke puts mean piston speed at 4,000 ft/min around 6,750 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 29.8 ci (488 cc).
At 16.5:1 this is a compression-ignition engine: the ratio is the heat source that lights the fuel, not a knock limit to be managed.
It is one of 2 engines in the Chevrolet 119ci family, all of them 119 ci — the differences between them are in compression, heads and rating, not displacement. 2 factory variants share these dimensions, rated at 151 hp across 2014–2015.
