After watching Land Cool Luze, I thought I thought that Toyota’s current development route is a personal color with Toyota. After reading the new NX released by Lexus, I am more definitely this idea.
Fighting to grab new energy, reduce carbon emissions, and stop research and development of new internal combustion engine technology is the current trend. Then Toyota is a new internal combustion engine, and the development route is that I can have no big displacement, but there is no internal combustion engine. So 3.5T V6 substituted 4.6L v8 This is the change in Toyota in the new generation of Rand Cool Road, and then replaces 3.5L V6 engine with a 2.4T engine.
Then Toyota took the first 2.4T engine on the New Generation NX in Lexus.
In exchange NX newly increased 2.4T engine
Lexus new NX is the second generation model after 2014 launched NX series.
Several information points, new car is based on TNGA-K platform, with a length of the vehicle body as 4660/1865 / 1640mm, and the wheelbase is 2690mm. Compared with the old NX, the body length, the width increased by 20mm, the height of the body increased by 5mm, and the wheelbase is 30mm.
Then, the new car gives four power schemes. The basic NX 250 is still used in the No. 2.5L engine, the maximum power is 203 horsepower, the maximum torque 250 cow middot; rice; then has NX 350h mix and NX 450H plug-in mixing model, two The car is equipped with the same 2.5-liter four-cylinder engine, which is equivalent to a 2.0-liter engine in the pure electric state, and the pure battery is 58 kilometers.
In addition to adding insertion mixing, the highlights on the power assembly have a 2.4T engine, which will sell in the market in the NX 350 naming method, the maximum power is 275 horsepower, Maximum torque 430 cow middot; rice, it will replace 3.5L naturally inhaled six-cylinder engines.
So, how is this 2.4T engine? Let’s take a look today.
Small displacement turbine is the future
of Toyota internal combustion engine
. The smooth driving of the vehicle is also sufficient power reserves. But with a turbine to make up for the low torsion, the big displacement is almost gone on the meaning of the car factory. Then the 2.0T engine can also press 260 horsepower power, complete enough home car.
So, before 2.4T is that a chicken rib is not low.
But now the meaning is different, and the 2.4T engine is fragrant. Using small displacement turbine engines to replace the old big displacement natural inhalation engine, it is the future development trend of Toyota internal combustion engines, so its technology must be excellent and the feeling must allow users to satisfy. Energy saving and emission reduction is the premise, but it has to accelerate the fast power enough. 
This engine is named T24A-FTS, analyzes that T is the name of the engine series, 24 is 2.4L displacement, and a refers to the TNGA architecture, f is the small valve angle DOHC, T is the turbine increase Pressure, S is the direct injection technology in the fuel cylinder.
According to the information released by Lexus, this engine adopts the interior direct injection technology, which can spray the oil and gas into the combustion chamber, and one thing is that the turbine and catalyst have been optimized. Let the peak torque of the engine can be released under a lower speed area, which can have better acceleration performance, followed by being optimized after optimization, and can better achieve the target of emission reduction. Therefore, this 2.4T turbocharged engine meets the strict emission standards of countries; and the main purpose of this engine is to replace the natural intake engine of 3.5L V6.
In
In the middle direct injection technology, it is not a new, and its addition is to increase the combustion efficiency to reduce fuel consumption. The middle direct injection is to improve the fuel economy on top of the piston in the top of the piston, through more accurate injection and better atomization effect. At the same time, the direct injection technique in the injector in the injector can also reduce cold start compared to similar cylinder direct injection engines.Hydrocarbon emissions.
Also, this 2.4T model only launches four-wheel drive models, and the electric control full-time four-wheel drive system is constantly changing from 75:25 to 50:50 based on scenes.
Of course, and the gearbox that matches the engine is also optimized, and the NX 350 is used in the Direct Shift-8AT gearbox capable of withstand a larger torque (previously mounted on the ES 260 and other models). Moreover, the gearbox is enlarged to reduce the gear transmission ratio, reducing the mechanical loss of the gearbox, thereby achieving high efficiency low fuel consumption. In short, this set of power assembly is to save oil; in the future, it will be used in the model of Lexus IS.
Summary
This 2.4T engine replaces the engine of 3.5L V6, solves the problem of existing V6 engine, replacing the traditional large discharge with small displacement turbine engine Engines are a feasible solution, which reduces fuel consumption and internal combustion engine models are sold in the market. This may be that Toyota’s final persistence of the internal combustion engine is also the future consideration of Toyota on the future of internal combustion engines.
