The Lexus GS,
the current third generation GS comes in both V6, V8, and hybrid versions. The GS
300, with a 3.0 L V6 3GR-FSE engine, and the GS 430 with the same 4.3 L V8 used
in the previous model. The GS 300 has a direct-injection engine for all markets
except for Continental Asia. A GS 350, using the 3.5L 2GR-FSE engine, replaced the
GS 300 for the 2007 model year. Due to a change in SAE testing procedures, the 2007
GS 430 horsepower rating was changed to 290 (with 319 ft-lbs. of torque) , while
the V6-powered GS 350 was rated at 303 horsepower (with 274 ft-lbs. of torque).
Lexus reports 0-60 times of 5.7 seconds for both vehicles. A 4.6L GS 460 is expected
to replace the 4.3L GS 430 by 2008.
The Lexus LX.
The current model LX 470, has a 4.7-liter, four-cam V8 engine with four valves per
The Lexus SC.
The first generation SC debuted as the V8-powered SC 400 in 1991, and the I6-powered
SC 300 was added in 1992. Both first generation models were produced until 2000.
The second generation model, the SC 430, went into production in 2001. The SC 430
features a hardtop convertible design and a V8 engine.
The Aristo was
launched in October 1991, offering two versions: the R6 3.0 (3.0V) with a 24-valve,
276 hp (205 kW) twin-turbo 2JZ-GTE engine, and the 3.0Q with a
226 hp (169 kW) 2JZ-GE engine. A third model, the 4.0Zi-Four joined the Aristo lineup
- A turbocharger is
a forced induction device used in internal combustion engines to improve
engine performance by forcing compressed air into the combustion chambers, allowing
more fuel to be burned, resulting in a larger power output.
- A turbocharger consists of a turbine
and a compressor linked by a shared axis. The turbine inlet receives exhaust gases
from the engine exhaust manifold causing the turbine wheel to rotate. This rotation
drives the compressor, compressing ambient air and delivering it to the air intake
of the engine.
- The objective of
a turbocharger is to improve upon the size to output efficiency of an engine
by solving for one of its cardinal limitations. A naturally aspirated automobile
engine uses only the downward stroke of a piston to create an area of low pressure
in order to draw air into the cylinder. Since the number of air and fuel molecules
determine the potential energy available to force the piston down on the combustion
stroke, and because of the relatively constant pressure of the atmosphere, there
ultimately will be a limit to the amount of air and consequently fuel filling the
combustion chamber. This ability to fill the cylinder with air is its volumetric
efficiency. Since the turbocharger increases the pressure at the point where air
is entering the cylinder, and the amount of air brought into the cylinder is largely
a function of time and pressure, more air will be drawn in as the pressure increases.
The intake pressure, in the absence of the turbocharger determined by the atmosphere,
be controllably increased with the turbocharger.
- The application of
a compressor to increase pressure at the point of cylinder air intake is
often referred to as forced induction. Centrifugal superchargers operate in the
same fashion as a turbo; however, the energy to spin the compressor is taken from
the rotating output energy of the engine's crankshaft as opposed to exhaust gas.
For this reason turbochargers are ideally more efficient, since their turbines are
actually heat engines, converting some of the kinetic energy from the exhaust gas
that would otherwise be wasted, into useful work. Superchargers use output energy
to achieve a net gain, which is at the expense of some of the engine's total output.
