Engine displacement. One complete cycle of a four-cylinder, four-stroke engine. The volume displaced is marked in orange. Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. [1] It is commonly used as an expression of an engine's size, and by extension as ...
The cubic inch was formerly used by the automotive industry and aircraft industry in North America (through the early 1980s) to express the nominal engine displacement for the engines of new automobiles, trucks, aircraft, etc. The cubic inch is still used for this purpose in classic car collecting.
By 1972, NASCAR phased in a rule to lower the maximum engine displacement from 429 cubic inches (7.0 liters) to its present 358 cubic inches (5.8 liters). [47] The transition was not complete until 1974 and coincided with American manufacturers ending factory support of racing and the 1973 oil crisis.
The ZZ632's iron block shares a mold with Chevrolet Performance's ZZ572 crate engines, but the castings are machined to accommodate the huge 632 cubic-inch displacement. The bore grows by 0.040 in (1.0 mm), compared to the 572-cubic-inch V8s, with most of the displacement gain coming from a stroke that is 0.375 in (9.5 mm) longer.
Displacement was 196 cubic inches (3.2 L). [2] In 1915 a new L-head water-cooled 201 cubic inches (3.3 L) inline-four engine appeared. [ 3 ] While International's own engines underwent constant developments, the pace of truck production in the twenties was such that others' engines (from Waukesha , Buda , and Lycoming for instance) had to be ...
The two inline engines were used through 1954, when Pontiac unveiled its OHV Strato Streak V8 in 1955. The development of this V8 dates back to 1946, when engineers began considering new engine designs for postwar cars. They came up with a 269-cubic-inch (4.4 L) L-head design. Pontiac engineers tested their 269 cu in (4.4 L) V8 in 1949 or 1950 ...
The 368 has the distinction of being the last traditional "big-block" cast-iron pushrod V8 engine available in a production car. It lasted through 1984 in the limousines. Rival big blocks, ranging in displacement from 396 to 460 cubic inches, disappeared between 1976 and 1978.
Chrysler Slant-6 engine. Polyspheric V8. The Chrysler flathead engine is a flathead automotive engine manufactured by the Chrysler Corporation from 1924 through the early 1960s. The flathead engine came in four-,six-, and eight-cylinder configurations and varying displacement, with both a cast iron and cast aluminum cylinder head.
