Consumers who are unable to install wall chargers in their own parking lots almost do not consider buying pure electric vehicles, but gasoline vehicles with fuel consumption and high carbon emissions are not economical and environmentally friendly to use every day, so "gasoline electric vehicles" have become the best option, which may be 12V or 48V light gasoline electricity, or hybrid or PHEV that can be plugged in externally.
For passenger cars, if electric vehicles are not a high-quality option (expensive, range anxiety, charging blockage, and winter aggravation), then "commercial vehicles" are unlikely to enter electrification in large numbers, after all, commercial vehicles are frequently used, have a longer driving range, and have to face the severe challenges of high capacity and high passenger capacity in the peak season.
If there is no revolutionary breakthrough in battery technology, then the electrification of commercial vehicles will probably only be limited to short-distance transportation in urban areas, and it will still be used with gasoline vehicles, and it will still not be able to achieve zero carbon emissions in cities. However, under the extreme restrictions of environmental protection regulations, the diesel engines of passenger cars are decreasing day by day, and the rate of death is faster than that of gasoline engines, and diesel engine commercial vehicles will inevitably face more stringent environmental protection regulations in the future.
Since electric vehicles are not feasible, diesel power is not environmentally friendly, and will eventually face the dilemma of having no horses to be listed on the road, then in the next 10 or 20 years, there may be only one option for the best power option for commercial vehicles, and that is a gasoline engine hybrid or PHEV.
Based on this thinking, Toyota's reaction speed will of course be faster than its competitors in the same class, and another important point is that Toyota definitely has a way to minimize the cost of commercial hybrid engines, after all, this is Toyota's expertise and strength. Toyota's initial commercial gasoline hybrid solution is a 2.4T 48V light gasoline electric direct injection turbo gasoline engine, which is different from the Hybrid design of general passenger cars, and the commercial vehicle adopts the simplest sandwich architecture, without a complex e-CVT built-in dual-motor gearbox, and the commercial light gasoline electric is in the middle of the 2.4T engine and the 8AT gearbox, which is in the engine flywheel position, sandwiched with a 48hp output, The electric motor with a maximum power of 20kgm can also be used as a generator, and a small 1.9kWh nickel-metal hydride battery module is hidden in the hidden part of the chassis. Okay, why is it a nickel-metal hydride battery module because it is cheap, not easy to spontaneously combust, safe and reliable, and durable.
Such a 2.4T light oil electric power can output 326hp maximum horsepower and 64.1kgm maximum torque, and the horsepower part is 48hp more is just a small supplement, but the torque part is increased by 20.4kgm is a big supplement!
This is very important for commercial vehicles with high loads. You may think that ~ why do ordinary commercial vehicles need so much power?A Hino 300 series 5-ton truck with a 4.0-liter diesel engine (6AT), the maximum horsepower is only 150hp/2700rpm, the maximum torque is only 44.9kgm/1300~2200rpm, and the maximum speed is only 110km/h.
It turns out that Toyota's 2.4T light fuel electric power must cover a wide range of commercial vehicle markets around the world, including the unique pickup truck culture in the United States, because the power output of pickup trucks and trucks of other competitors Ford, Chevrolet and RAM is also very strong, and even does not hesitate to use V6 engines, so Toyota does not dare to be careless in this power output.
Moreover, Toyota's 2.4T light oil electric power can actually reduce cost and power through castration action, such as canceling the turbocharger and returning to the spontaneous combustion intake engine, but in the case of the 2.4-liter or 2.5-liter NA engine, it is easy to introduce the valve early closing system (the original factory called the Atkinson cycle) and output 150hp and 22kgm maximum power, which can take into account energy saving and low-speed torque output, with 48hp, After the 20.4kgm electric motor, the maximum torque output is comparable to that of the current 4.0-liter commercial diesel engine (only the final transmission ratio needs to be adjusted), ensuring that it is more environmentally friendly, fresher, smoother, quieter, easier to recruit good drivers, and does not require regular urea addition and combustion catalyst carbon deposits. In fact, the power output of the 2.4T light gasoline electric gasoline engine is enough to cover a 10-ton commercial vehicle. At present, the 5.1-liter diesel engine of the Hino500 series 10-ton commercial vehicle has a maximum horsepower of 240hp/2300rpm and a maximum torque of 81.0kgm/1400rpm.
As for the commercial vehicle engine of more than 10 tons, because the number is not high, compared with the mainstream 5-ton commercial vehicles, so in the future, it is still advocated to maintain the diesel engine, at most for the diesel power external Hybrid system, the purpose is simply to strive for "compliance with environmental protection laws and regulations, legal listing on the road", if it is determined that the diesel engine is to be wiped out, well, when the time comes, see if the time comes to use pure electric, hydrogen energy, natural gas engine, environmentally friendly low compression ratio Hybrid diesel engine, V6 gasoline Hybrid power "again" It is difficult to decide at this time. However, it has not yet reached the point where the 2.4T light oil electric power replaces the low-end commercial diesel engine.
First, environmental protection regulations are not so stringent;
Second, the current commercial diesel engine and gearbox have been used for many years, with extremely low cost, good reliability and durability, fast and economical logistics maintenance, and there is no reason to eliminate it at all;
Third, 2.4T light oil electric or its derivative power, there is no such large production capacity and price advantage, the cost can still not be effectively reduced, and so on after the small displacement diesel engine is finished, it is still too late to transform the production line, as long as you concentrate on the US market;
Fourth, the fuel consumption of replacing 2.4T light fuel with electric power from diesel power will not be relatively economical! At best, the light gasoline engine will be more comfortable and quiet, and the exhaust will not be so smelly, if it is not subject to environmental regulations, in fact, there is no need for diesel engines to be replaced.
However, from this point of view, the cost of logistics and passenger transportation will rise higher and higher in the future, which means that low prices have become a thing of the past, and the future will usher in "inflation will eat up your pension and travel funds", forcing the elderly to dare not retire and young people to dare to buy things indiscriminately, but it is best to change the luxury consumption and living habits from now on, so as not to feel pain and pressure in the future.
