A <a href="/wiki/Balance_shaft" title="Balance shaft">balance shaft</a> is sometimes used to reduce the vibrations caused by the rocking couple. </p><p>Other crankshaft angles have been used occasionally. The 1976–1981 <a href="/wiki/Laverda_Jota" title="Laverda Jota">Laverda Jota</a> motorcycle used a 180 degree crankshaft, where the outer pistons rise and fall together and inner cylinder is offset from them by 180 degrees. This results in three power strokes evenly-spaced at 180 degrees each, and then no power strokes during the final 180 degrees of crankshaft rotation. The 2020 <a href="/wiki/Triumph_Tiger_900_(2020)" title="Triumph Tiger 900 (2020)">Triumph Tiger 900</a> motorcycle uses a "T-Plane" crankshaft where the crankshaft throws are at 90 intervals, such that the throws for cylinders 1 and 3 are separated by 180 degrees (therefore the three throws together forming a "T" shape when viewed from the end).<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Usage_in_cars">Usage in cars</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Straight-three_engine&action=edit&section=2" title="Edit section: Usage in cars"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Tuned-SAAB-twostroke.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/6/65/Tuned-SAAB-twostroke.jpg/220px-Tuned-SAAB-twostroke.jpg" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/6/65/Tuned-SAAB-twostroke.jpg/330px-Tuned-SAAB-twostroke.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/6/65/Tuned-SAAB-twostroke.jpg/440px-Tuned-SAAB-twostroke.jpg 2x" data-file-width="2048" data-file-height="1536" /></a><figcaption>Circa-1960 <a href="/wiki/Saab_two-stroke" title="Saab two-stroke">Saab two-stroke</a> engine</figcaption></figure> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Suzuki_K10B.JPG" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Suzuki_K10B.JPG/220px-Suzuki_K10B.JPG" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Suzuki_K10B.JPG/330px-Suzuki_K10B.JPG 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Suzuki_K10B.JPG/440px-Suzuki_K10B.JPG 2x" data-file-width="1600" data-file-height="1200" /></a><figcaption>2010 <a href="/wiki/List_of_Suzuki_engines#K_engine" title="List of Suzuki engines">Suzuki K10B</a> engine</figcaption></figure> <p>Among the first cars to use a straight-three engine is the 1953–1955 <a href="/wiki/DKW#Automobiles_made_after_1945" title="DKW">DKW F91</a>, powered by a 900 cc (55 cu in) <a href="/wiki/Two-stroke_engine" title="Two-stroke engine">two-stroke engine</a>, although this was predated by the 3 cylinder 15hp Rolls Royce produced in 1905 and a number of other cars of this era also used 3 cylinder engines.
