The cubic inch (symbol in 3) is a unit of volume in the Imperial units and United States customary units systems. It is the volume of a cube with each of its three dimensions (length, width, and height) being one inch long which is equivalent to 1/231 of a US gallon.
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 an indicator of the ...
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 ...
A 250 cubic-inch inline-six was standard, with the option of a 292 cubic-inch inline-6, a 307 cubic-inch V8, a 350 cubic-inch V8, and a 454 cubic-inch V8. [41] [42] Available only in two-wheel drive C-series trucks, the 454 replaced the 402 cubic-inch "396" V8; the 307 was offered only for 1973. [2]
The 400-cubic-inch (6.6 L) was produced from 1967-1969. This engine has a bore and a stroke of 1968 Wildcat 430 CID engine. 4.04 in × 3.9 in (102.6 mm × 99.1 mm). It was the only large V8 engine available for the intermediate-sized A-body Buicks due to the GM cubic inch limit restriction in effect through 1970. [6]
A 251.92 cubic inch (4,128.29 cm³) DOHC naturally-aspirated four-cylinder racing Offy with a 15:1 compression ratio and a 4.28125-by-4.375-inch (108.744 mm × 111.125 mm) bore and stroke could produce 420 hp (310 kW) at 6,600 rpm (1.77 hp per cubic inch, 81 kW/L) making it remarkably power-dense. Other variants of the engine produced even ...
In 1949 Cox developed their own engine for their racing tether car which included some parts from Mel Anderson's Spitzy engine. This engine was called the "O Forty Five" as it was .045 cubic inch displacement. In 1950 with sales of the car proving to be a success Cox moved on to development of a model plane engine. [3]
The Detroit Diesel Series 71 is a two-stroke diesel engine series, available in both inline and V configurations, manufactured by Detroit Diesel. The number 71 refers to the nominal displacement per cylinder in cubic inches, a rounding off of 70.93 cu in (1.2 L). Inline models included one, two, three, four and six cylinders, and the V-types ...
