Insensitive to in-line 6-cylinder engine? Come fresh, take you into the V8 world in minutes
In the current truck circle, light trucks and heavy trucks have been overruled by in-line engines. Most drivers have become familiar with in-line 4-cylinder and in-line 6-cylinder engines. It is time for trucks to adopt some new forms. The engine , to create some new sense for the user, such as the heavy truck V8 engine we will introduce next.
V8 engine Compared to in-line power, the 8 cylinder V-shaped V8 engine has various advantages in terms of power reserve, low speed and large torque, and continuous acceleration capability, making this type of engine unstoppable with high stability and high power. .
"Old drivers" all know that under the same displacement, as the number of cylinders of the engine gradually increases, the more the number of cylinders and the smaller the bore diameter, the pistons and connecting rods will be easier to lighten, the rotation speed will be more easily climbed, and the crankshaft will rotate more. From a small angle, there will be a deflagration work to obtain a higher power, while achieving an excellent throttle response.
Once the number of cylinders exceeds 8, the engine performance will change from quantitative to qualitative, not only will have a thick and dense engine noise that makes people intoxicated, but also have smoothness, smooth power output, and low-rotation torque output. Four-cylinder, six-cylinder machine is much better. The number of cylinders in the 4-6-8 cylinder changes step by step, which is an important demarcation zone for piston engines. The driving experience of the V8 engine with the user must be even more awkward, and the driver is even "poisoned."
V8 engine piston working process The motive of power must be the most intuitive manifestation of high horsepower. In the same volume compared to the in-line engine, V8 engine power can easily enter the ranks of 500 + horsepower, even to 600,700 horsepower also feel that there is not much pressure. In particular, the logistics industry's emphasis on the timeliness of cargo transportation and the user's concern for fuel economy, the economical speed range and strong dynamic advantages of the V8 engine are all the more obvious.
In addition to the horse power level increase, the volume of the V8 engine is also attractive enough for the user. Xiao Bian learned that the most common angle of the piston angle in the current V8 engine is 90 degrees, with the most ideal ignition and vibration characteristics. The original 8-cylinder engine was mostly an in-line eight-cylinder configuration, but due to structural and safety considerations, the more compact and shorter V8 engine replaced the inline 8-cylinder structure. The current V8 engine has almost the same size as the inline 6-cylinder engine. The V8 engine with its advantages of volume can easily be placed under the heavy-duty cab, and it may also expand the space for the cab.
Of course, V8 power is mentioned in the truck lap. Scania, the "king of roads", will certainly be the first to break into the minds of users, but recently Xiaobian learned that a new force has emerged in the heavy-duty V8 field, China. Heavy-duty trucks burst out a V8 engine that can be used in tractors or other areas.
China National Heavy Duty Truck V8 Engine
According to Xiao Bian from China National Heavy Duty Truck related personnel to get the news, the explosion of this V8 engine displacement of 15L, the highest power can reach 680 horsepower, is currently undergoing internal tests. As far as the horsepower segment is concerned, once this V8 engine is equipped with a tractor to China National Heavy Duty Truck, CNHTC may be the first company in the domestic road transport sector to enter the ranks of 600+ horsepower.

After all, from the point of view of process and performance, V8 engines are all attached to high-end, so Xiaobian speculated that if this 680-horsepower Sinotruk V8 engine is used in the highway field, it will be preferentially equipped with relatively high-end such as the Judeka and Howo T7H. The tractor products will further expand Sinotruk's leading edge in the high-end high-power field.
When this V8 engine can be tested on the road and when it can be delivered to the users, we are still not sure about it, but it is certain that this landmark V8 engine will certainly arouse the user's curiosity. Give the user enough freshness.
