For example, if the static compression ratio is 10:1, and the dynamic compression ratio is 7.5:1, a useful value for cylinder pressure would be 7.5 1.3 × atmospheric pressure, or 13.7 bar (relative to atmospheric pressure). The two corrections for dynamic compression ratio affect cylinder pressure in opposite directions, but not in equal strength.
The Lexus RCF GT3 utilises a re-stroked version of this engine which displaces 5.4 litres and makes 373 kW (500 bhp; 507 PS). [3] In the IS F, the engine had an 11.8:1 compression ratio and produced 310 kW (416 bhp; 421 PS) @ 6,600 rpm and 51.3 kg⋅m (371 lb⋅ft; 503 N⋅m) @ 5,200 rpm of torque. [4]
This creates a large amount of swirl in the combustion chamber. Injectors are mounted in the head, rather than conventionally in the intake manifold. Compression ratio 9.5:1. [7] The 1998cc 3S-FSE engine is a direct injection petrol lean-burn engine. Compression ratio 10:1. [8]
For example, uncompressed songs in CD format have a data rate of 16 bits/channel x 2 channels x 44.1 kHz ≅ 1.4 Mbit/s, whereas AAC files on an iPod are typically compressed to 128 kbit/s, yielding a compression ratio of 10.9, for a data-rate saving of 0.91, or 91%.
Bore is 95 mm (3.7 in) and stroke is 88.4 mm (3.5 in). The compression ratio is 9.1:1. [34] It was replaced by the 4.8 L Vortec 4800 LR4 for the 1999 Chevrolet Silverado/GMC Sierra trucks and 2003 Express/Savana vans. In C/K trucks, the 5000 produces 230 hp (172 kW) net flywheel at 4600 rpm and 285 lb⋅ft (386 N⋅m) net flywheel torque at ...
The Chevrolet 90° V6 family of V6 engines began in 1978 with the Chevrolet 200 cu in (3.3 L) as the base engine for the all new 1978 Chevrolet Malibu.The original engine family was phased out in early 2014, with its final use as the 4.3 L (262 cu in) V6 engine used in Chevrolet and GMC trucks and vans.
6.5: 6,498 cc (396.5 cu in); bore x stroke: 95.0 mm × 76.4 mm (3.74 in × 3.01 in), compression ratio: 11.8:1 cylinder block & crankcase cast aluminium alloy cylinder heads & valvetrain cast aluminium alloy; four valves per cylinder, 48 valves total, double overhead camshaft aspiration
The 2.5 L; 151.8 cu in (2,488 cc) L5 4-cylinder engine has an 89 mm (3.50 in) bore and a 100 mm (3.94 in) stroke, with a compression ratio of 9.7:1. The standard crankshaft is cast iron with eight counterweights. To increase durability of the bore, Mazda uses cast iron for the cylinder liners.
