In 1997, Toyota's VVT-i variable valve timing technology was introduced along with a further compression ratio increase to 10.5:1, [2] bumping power and torque to 216 kW (290 hp; 294 PS) at 5,900 rpm and 407 N⋅m (300 lb⋅ft) at 4,100 rpm. For the GS 400, output was rated at 224 kW (300 hp; 305 PS) at 6,000 rpm and 420 N⋅m (310 lbf⋅ft) at ...
The basic 4A is a SOHC 8 valve carburated engine which produces 78–90 PS (57–66 kW; 77–89 hp) at 4800 rpm and 115 N⋅m (85 lb⋅ft) of torque at 2800 rpm, though the power and torque output figures vary between different regions of the world. in European versions, the combustion chambers were reformulated in early 1986, resulting in an ...
The 322 Fireball V8 in a 1956 Buick Century. Buick's first generation V8 was offered from 1953 through 1956; it replaced the Buick straight-eight.While officially called the "Fireball V8" [1] by Buick, it became known by enthusiasts as the "Nailhead" for the unusual vertical alignment of its small-sized valves (Originally it was known to hot-rodders as the "nail valve", because the engine's ...
(2006–2008) Readout changed to SAE standards, Revised to 258 hp (192 kW)at 6200 rpm and 233 lb⋅ft (316 N⋅m) of torque at 5000 rpm - *No change was made to engine, only SAE readout which changed the HP numbers; 2007–2008 (With revised bellhousing) Acura TL; Variable Valve Timing and Lift Electronic Control (VTEC) Dual-stage induction system
With traditional fixed valve timing, an engine will have a period of "valve overlap" at the end of the exhaust stroke, when both the intake and exhaust valves are open. The intake valve is opened before the exhaust gases have completely left the cylinder, and their considerable velocity assists in drawing in the fresh charge. Engine designers ...
The 2.5-litre 6G73 is a 24-valve SOHC design with two valves running off a single cam lobe on the exhaust valves using a forked rocker arm and each intake valve actuated with two cam lobes, with a smaller bore than the 3.0L version of the same block. Bore and stroke are 83.5 mm × 76 mm (3.29 in × 2.99 in); it is a 60-degree V6 and weighs ...
The Toyota 1ZR-FAE is a DOHC, 16-valve, 1.6 L (1,598 cc) engine also equipped with Dual VVT-i and VVT-Li. Output for this engine is rated at 132 hp (98 kW) at 6400 rpm and 118 lb⋅ft (160 N⋅m) of torque at 4400 rpm for most applications.
It is fuel injected, has an aluminum-alloy cylinder block and cylinder head, is a SOHC 16-valve design (four valves per cylinder) and utilizes Honda's i-VTEC system. The R series engine has a compression ratio of 10.5:1, features a "drive by wire" throttle system which is computer controlled to reduce pumping losses and create a smooth torque ...
