45 percent more efficient fuel of V-6 engine from the GS450h 45
Toyota City, - According to Lexus, the consumption of fuel of V-6 engine from the GS450h 45 percent more efficient than previous models thanks to the application of several new forementioned technologies and improvements in several components of the machine. For example, application of D-4S system, direct injection technology with more pressure.
To obtain a higher spray pressure, nozzle diameter is reduced. Form of spray gasoline in the combustion chamber changes from a fork into the fan. Air and fuel are getting easier and coherent. The result, the combustion process takes place with ease.
Gasoline Engine
In addition to the direct injection system, combustion chamber shape and cooling system is also improved its performance. For the engine compression ratio increased from 11.8 to 13.0:1 shoot without causing symptoms (knocking). 217 engine was producing power kW@6.000 Nm@4.500 rpm and 356 rpm.
HS450h hybrid system is made by combining two motors, planetary gear and two-speed deceleration mechanism.
Electric motor
Dihasillkan power and torque electric motor 47 kW and 275 Nm. With this addition, if both drivers are combined, the Lexus GS450h power to 256 kW.
Further, the DC-DC koverter car is no longer placed in the trunk, but was transferred to the engine room. This can be done because the smaller size though equipped with a water cooling system.
To drive it, GS450h equipped with four choices of modes, ie ECO, Normal, Sports and Sport S +. To get the last disebutkah conditions, the voltage or voltage from the battery to the motor is increased from 500 volts to 650 volts.
Another new technology is the headlights Hi / Lo or to close and distant type of LED. The same technology is also used for the taillight design with L which is a symbol of the Lexus.
With the addition of all these technologies, create new Lexus GS450h has to be sold at a price of 8 million yen in Japan.
In order for the fuel consumption of the Lexus GS450h (HEV: Hybrid Electric Vehicle) which will be launched next March 19 in Japan more efficient again, Toyota is applying some new technology. Especially for machines - like the Prius - added Atkinson cycle. As for the supply of fuel, direct injection system used.
The result, this car 3500 cc petrol consumption is claimed to 18.2 km per liter (kpl). In fact, if the test is measured by the 10-15 Japanese test methods, hasilmya more efficient again, that is 20.5 kpl.
