With the cooler temperatures, the content of which is consumed by the engine air of Toyota Grand New Fortuner VN Turbo becomes more dense oxygen content is one of the most important elements to get a more complete combustion process.
That's why Toyota Grand New Fortuner VN Turbo's engine capable of producing much higher performance, but with fuel consumption more efficient in conjunction with the reduction of CO2 emissions generated content.
IN the sidelines of the media test drive the Toyota Grand New Fortuner VN Turbo, consumers get the exposure about technology conceived by SUV engine andalanToyota Motor.
the presence of this variant with new engines since the beginning of new technologies implemented in the latest Toyota Hilux 3.0-liter engine.
Due to a production base in Thailand does not provide VN Turbo diesel engine variants for the 2.5-liter engine capacity, it takes research and preparations long enough to be applied to the 2.5-liter engine.
The test also needs to be done so that when installed on vehicles that will be sold, this machine does not meet the various constraints related to the quality of the fuel, and various other parameters.
Therefore, to be able to bring this innovation the Toyota spent about two years for this vehicle ready to compete. VN Turbo 2.5-liter engine is the exclusive engine for market.
With the launch of Grand New Fortuner VN Turbo (zozzle variable turbo), TM tried to answer complaints brought by the owners of the old Fortuner expressed their dissatisfaction at the performance of the engine that are considered less powerful.
With technology disisipkannya variable nozzle turbo on the device plus the addition of the intercooler, turbo diesel engine power 2 KD-FTV that previously could only release the power of 102 ps at 3600 rpm, is now capable of heading the number 144 ps at 3400 rpm.
And the most important is the torsional strength machines that were previously only able to carve the maximum 260 Nm can now be tilted significantly to 343 Nm at rev range between 1,600 to 2,400 rpm.
This combination results in an increase in the run-down power that is needed when crawling in traffic jams or during take off on the road uphill. While at high speed, energy boosted thanks to the presence of the intercooler is able to make the air that enters the engine becomes more dense.
enhancement Fortuner VN Turbo engine which increased by 40 horsepower than the previous generation thanks to improvements obtained in the combustion process in the engine.
Turbo function on the machine is to help accelerate and enrich the amount of air flow into the engine cylinders. Turbo itself works by using the flow of air from combustion that normally is wasted through the exhaust pipe.
Combustion air pressure is used to rotate the propeller shaft connected to the turbine on the other side. Turbine is working to suck fresh air as much as possible to be pumped into the engine intake duct.
"As more and more air into the engine, more power can be obtained by increasing the supply of fuel,".
Unfortunately, the conventional turbo as it has drawbacks. propeller in the turbo can provide effective air pressure when the engine is spinning at a certain rpm, so the ideal lap time is not reached, an advanced turbo useless.
"This phenomenon is known as turbolag. Ie the gap before the turbo is spinning at the speed of using a Variable Nozzle Turbo ideal.Dengan, these symptoms can be minimized".
In VNT turbo, inside the house to added into turbine fins angle can vary according to the command from the computer. Fins function is to direct and narrow air holes through the turbine player.
By narrowing the fins, making the air flow faster. That way, VN Turbo was able to react optimally without waiting for the engine speed rises, so that the energy gap is not too long 'empty'.
"This principle can be like a water hose. If the end of the hose is left alone, the water will flow as it is. Yet when we hit the end of the hose so that the hole narrows, the water pressure becomes tighter discharge although not much,".
Because the air pressure from the turbo utilizing exhaust heat, of course, make this tool also heat the air that is inhaled impact helped expand so that oxygen molecules become tenuous. At this moment intercooler play.
Before the air supplied by the turbo into the engine intake ducts, intercooler first flowed to the basic principle is similar to the water radiator. The difference is the cooled air into the intake tract.
The device is placed just above the right engine under the bonnet. To allow air to flow in semain many intercooler grille, the hood with an added 'air scoop' so as to catch more cold air flow when the vehicle is running.
