The AJ133 is a 90° V8 engine available in either supercharged or naturally aspirated form, with a bore & stroke of 92.5 mm × 93 mm (3.64 in × 3.66 in) and a compression ratio of 9.5:1 for the supercharged version and 11.5:1 for the naturally aspirated one respectively.
Their second unit is a 6.4 L naturally aspirated Apache V8 engine that originally made 470 hp (350 kW; 477 PS) but was upgraded to produce 485 hp (362 kW; 492 PS) after 2014. SRT's most powerful variant is a 6.2 L supercharged V8, with two separate units used on the Hellcat and Demon models. The Hellcat's version makes 707 hp (527 kW; 717 PS ...
The centrifugal supercharger draws its power from the movement of the drive where it is attached. At this point, the supercharger powers an impeller – or small rotating wheel. The impeller draws air into a small compressor housing (volute) and centrifugal force sends the air into the diffuser.
The 1969–1972 Aston Martin DBS V8 coupe/convertible was Aston Martin's first V8 model. This engine was an all-aluminium construction with double overhead camshafts and was used in several models up until 2000 when the Virage model was discontinued.
The rumbling exhaust sound produced by a typical cross-plane V8 engine is partly due to the uneven firing order within each of the two banks of four cylinders. A usual firing order of L-R-L-L-R-L-R-R (or R-L-R-R-L-R-L-L) results in uneven intake and exhaust pulse spacing for each bank.
The "60s" were used for V8 engines and the "70s" were used for V12 engines, therefore the V10 was allocated in the "80s" (despite having fewer cylinders than the V12 engines in the "70s".) The engine code for the related BMW S65 V8 engine reflects its link to the S85. The S65 code was selected to signify that the V8 is largely derived from the ...
The engine's crowd-pleasing sound was caused by its gear-driven centrifugal supercharger, which turned at more than five (5.35) times the crankshaft speed, giving it a scream at full power. [10] The engine's four camshafts and oversized-valve design also contributed to an exhaust noise much louder than other engines of its period, resulting in ...
The disadvantages of crank and camshaft twisting were not considered at this time, since aircraft engines of the time ran at low speeds to keep propeller tip speed below the speed of sound. Unlike the V8 engine configuration, examples of which were used in De Dion-Bouton , Scripps-Booth , and Cadillac automobiles by 1914, no straight-eight ...
