On March 14, 2017, Dongfeng Cummins announced the king of the 560-horsepower five- engine of the ISZ13L engine in the third season of the Dongfeng Tianlong China Truck Driver Contest. The release of the horsepower model can be said to be the signal that Dongfeng Cummins has delivered in the industry: it will continue to lead the trend of big horsepower. At the same time, the model also created a powerful contender for the high-horsepower engine market.

At the conference, China Truck Network reporter interviewed Gong Zuowei, director of customer engineering of Dongfeng Cummins. General Introduction to Gong: The Dongfeng Cummins ISZ13L engine is an internationally-reliable heavy-duty engine that is developed and designed based on international leading standards and brings together many of Cummins' latest technological achievements. It can fully meet the needs of long-distance dedicated and efficient logistics transportation users. Dongfeng Commercial Vehicle has two ISZ series engines out of the four new vehicles announced this time, indicating that Dongfeng Commercial Vehicles attaches great importance to the high horsepower tractor market.
Defining the ISZ13L engine as a strong competitor does not simply mean that the engine has an absolute advantage in horsepower. At the same time, Dongfeng Cummins's technicians also systematically optimized the performance of various aspects of the product.
"Improvement of engine and vehicle matching can improve competitiveness." According to the China Truck Network reporter, Dongfeng Commercial Vehicle and Dongfeng Cummins have optimized the ISZ series engine and throttle response. “In the section of climbing or continuous climbing, what kind of performance should the engine have and how much torque the engine should send according to the size of the throttle is very elegant. However, the ISZ13L series engines released this time have undergone new optimization and debugging. Under conditions that can produce greater power, small throttle or throttle can show its performance advantage." Gong said.

In addition, Dongfeng Cummins optimized the fuel consumption curve for the transport characteristics of high-powered tractors. At present, the engine speed of a large horsepower tractor is generally 1000-1200 rpm under normal operating conditions, and the normal operating speed is around 1100. The Dongfeng Cummins technical team has specifically optimized the fuel consumption curve for this rpm region. "Optimized fuel economy is 2-3% better than other products," Gong said.
The China Truck Network reporter learned at the scene that the ISZ13L engine released this time has also improved its fuel-saving switch. The fuel-saving switch of this model is no longer divided into no-load, half-load and full-load gears. Only economic gear (E gear) and power gear (P gear) are two gears. The driver can be switched at any time through a simple button switch. According to their own fuel-saving desire to switch between the two different engine operating modes, as long as you want to save in the case of fuel savings in the E file, you want power to hit the P file. This further improves the engine's power and acceleration control.
“As a market competitor, the trust of users is indispensable.†According to Gong, Dongfeng Cummins has a professional team to track the performance of the products after they are put on the market. Through big data, technicians can learn more about the real-time engine. status. From the perspective of comprehensive product performance, strong engine power and stable performance are the most direct experience for users. Gong said: Since the Dongfeng Cummins ISZ13L series was put into mass production in April 2016, it has produced more than 6,000 units, which is enough to prove the quality performance of the ISZ series engines and the users' affirmation of the products.
It is understood that the current US 6-axis tractor has a limited weight of 36T, but the tractor is still mainly high-powered, and there are even 600-horsepower models. This is precisely due to the timeliness of the US logistics industry. Nowadays, the timeliness requirements of China's logistics market are also constantly increasing, so high-powered tractors will also be the development trend of some market segments. In the high-powered engine field, the 560-hp Dongfeng Cummins ISZ13L engine deserves to be a strong competitor.
The Plasticizer DINP is di isononyl phthalate (DINP), which is formed by esterification of phthalic anhydride and isononyl alcohol. DINP is a general plasticizer. One of the main raw materials of DINP, isononanol (INA)
Compared with DOP, DINP has a larger molecular weight and a longer carbon chain. Therefore, it has better aging performance, anti migration performance, anti extraction performance and higher high temperature resistance. Correspondingly, under the same conditions, the plasticizing effect of DINP was slightly worse than that of DOP. It is generally believed that DINP is more environmentally friendly than DOP.
DINP, as a main plasticizer, is widely used in various soft PVC products. Such as wire and cable, film, PVC leather, PVC floor leather, toys, shoes, edge banding, sheath, wig, tablecloth, etc. DINP also has a small number of applications in some rubber products and coatings.
DINP is an oily liquid under normal conditions and is insoluble in water. Generally, it is transported by tank trucks, and small batches are transported by iron drums or special plastic drums.
Advantages of DINP plasticizers:
1. Stronger anti-aging ability, can prolong product life2. Plastics are easier to coat, spray and dip
3. Higher durability, more resistant to outdoor low temperature
4. Compatible with auxiliary plasticizers, thus further reducing costs
5. Low volatility, which helps to reduce volatile in the process and improve working conditions
6. Lower density, lower energy consumption and higher extrusion output than DOP
