Chapter 1274: Research the V8 engine


Prior to this, domestic diesel engines had never been developed on their own. All engines were imitated, even small internal combustion engines, that was an investigation of industrial heritage.
Needless to say, the heavy-duty diesel engine used by heavy trucks, even if it is the engine used in small cars, look at later generations. With the nose of an old Mitsubishi, how many independent car companies have been supported? Even before Qin Guan crossed, there were still some companies that didn't want to make progress, and they continued to use this old Mitsubishi nose.
Northern Heavy Truck Factory is a well-known enterprise in China, but now their engines are still developed on the basis of WD615. It is not so easy to establish a first-class engine research and development system.
Now is a good opportunity to take advantage of this project to raise the power system of heavy truck engines to a higher level.
This in-line six-cylinder engine still has potential. For example, in later generations, there was an engine code-named YCK15. Through the expansion of the cylinder, the displacement reached 15.26 liters, and the maximum power reached 650 horsepower.
This 6-cylinder, 4-valve National VI engine has two power sections of 600 horsepower and 650 horsepower to choose from, and the maximum torque is 2800 and 3200 Nm, respectively. This can be achieved when the engine is 1000 to 1500 rpm. Maximum torque output. What's more worth mentioning is that its B10 life is as high as 1.6 million kilometers, which is among the best in domestic engines.
It can be said that this kind of high-efficiency engine is the most needed for domestic heavy-duty trucks. If such a power can be developed on the basis of our own engines, it can truly be called a heavy-duty truck factory representing the world's advanced level.
However, Heribala shook his head: "No, we already have a foreboding that 400 horsepower is a big limit. It is difficult to break through upwards. If you want to achieve a power of 600 horsepower or more, Then, we’d better start anew and get a V8 engine."
Among in-line engines, six cylinders is the largest. If you increase the number of cylinders, the length of the engine will increase further, making it impossible to place it. So, if you go up, it will be a V-shaped layout with four cylinders on each side. Effectively reduce the overall length of the engine.
In fact, among the six cylinders, there is a difference between an inline six cylinder and a V-type six cylinder. The V-shaped layout is more reasonable, but it also tests the designer more.
Now, if you want to continue to increase the displacement and increase the power, it is best to achieve by increasing the number of cylinders, then you must get a V-type engine.
"If we develop a V-engine, then we have to find a suitable research object." Qin Guan said.
Now, the tank engine is also V-type, but this kind of engine is not comparable. It must be the same vehicle diesel engine, so that it can achieve high horsepower while maintaining certain economic performance and reliability. It will not only run for a few hundred. Hours of tasteless.
At the same time, it’s impossible to conduct self-research. The best way is to find a model to imitate it.
"Yes, Brother Guan, if we launch this new engine project, the best way is to imitate the engine of the Scania heavy truck in Europa." Heri Bara said.
In the field of heavy-duty trucks, Steyr is actually not well-known, it is precisely because it is not well-known, it can cooperate with Han.
The three major heavy-duty truck manufacturers in Europa are Mercedes-Benz, Volvo and Scania. Scania is the most famous and is known as the king of trucks.
As early as 1969, Scania introduced a 14-liter V8 engine with an output of 350 horsepower. It was known as the strongest truck diesel engine in Europa at that time.
The Scania LB140 model equipped with this V8 engine quickly gained a lot of attention. In daily operation and use, this engine can output high torque at a lower speed. Such power characteristics are quite attractive to heavy-duty vehicle drivers.
Since then, with the V8 logo on the door, it has become the most desirable engine for heavy truck drivers.
By 1991, Scania’s 100th anniversary, launched a full range of engines upgraded to Euro One emission standards, including two V8: a 450-horsepower high-pump diesel engine, another 500-horsepower electronic injection diesel engine, the latter It was also the first Scania engine to break through 500 horsepower.
In other words, in the 1990s, the world's most advanced heavy-duty truck engine only transitioned to 500 horsepower.
Later, in 2000, Europa implemented Euro III emission standards, and Scania introduced a new engine, and the 16-liter V8 model replaced the original 14-liter V8 model. The new engine adopts a modular design, and many parts are common to the 11- and 12-liter six-cylinder engines.
With the continuous introduction of a new series of V8 engines, the output power includes 500, 560, 620 horsepower, and the maximum torque reaches 3000 Nm.
But now, it's only in the 1980s. It is too high to have a heavy-duty truck with more than 600 horsepower.
"We now have the most sophisticated machining technology, we can further increase the pressure of the fuel system, through these ways to effectively increase the power of the engine." Heribala said: "We have to use our current electronic level The electronic injection system is used to improve the combustion of the engine. Through these measures, the performance of the engine can be further improved. If you accept our technical route, we can carry out a series of research and strive to develop such an engine. "
How has engine technology improved? One of the most important points is to increase the pressure of the oil pump. The higher the pressure, the better the atomization of diesel fuel, and the easier it is to achieve complete combustion, so as to significantly increase the power while maintaining the fuel consumption rate. These items are actually The North Heavy Truck Plant has been in pre-research.
Now, it just happens to have a demand, just put on a V8 engine to achieve an upgrade of the power system!
Qin nodded his point of view: "You can do it boldly. If you encounter funding problems in development, our head office can continue to support."
Qin Guan doesn’t know exactly how to do it. Qin Guan is good at delegating power and allowing his subordinates to do it boldly. As for burning huge amounts of funds, it doesn’t matter. The profitability of NORINCO is very strong. Besides, he There is also a currency cemetery.
It’s been a long time since I started the road of exchange. Now, if necessary, I can exchange a sum of funds. And now, it’s also possible to exchange Eagle Country’s currency. We already have a lot of foreign exchange reserves, so we can use it together with money from the currency cemetery. Nor will it be noticeable.
Suddenly, Qin Guan frowned. He used his mental point to scan the system and found that unexpected guests had arrived.
