Most straight-3 engines employ a crank angle of 120° and are thus rotationally balanced; however, since the three cylinders are offset from each other the firing of the end cylinders induces a rocking motion from end to end. The use of a Balance Shaft in antiphase to that vibration produces a smoothly running engine. AUTOMOBILE USE The straight-3 is the smallest engine in use in modern cars, generally for Engine Displacement s of around 1.0L. Cars in the 'super-mini' class often use them on base models, as do the Japanese Keicar s. A straight-3 is also used in the Suzuki Swift , its American cousin the Geo Metro , the Subaru Justy , the Honda Insight , and also Two Stroke Saab s ( 93 - 96 ). One experimental Saab had ''two'' transverse straight-3 engines, the '' Saab Monster ''. The Smallest straight-3 engine was the 543 cc Suzuki ''F5A'' used in the 1982 Cervo . Smart currently produces a diminutive 799 cc Diesel straight-3, the smallest ever. Most straight-3 engines fall below 1.2 liters, with a 1198 cc Volkswagen unit seen as the largest petrol unit. A 1.8 L (1779 cc) Diesel was produced by Alfa Romeo for their 1984 33 ''1.8 TD'', the largest straight-3 ever produced.
