Dongfeng Cummins ISZ 13-liter engine in the eyes of Tianlong Brothers

Ten years ago, Dongfeng Cummins began localized production of all-electrically-controlled Euro III engines. Today, the country’s four electronically controlled engines are fully promoted and the national five policy has roared out. Ten years ago, the Dongfeng Cummins ISZ 13-liter electronically controlled engine prototype was at the Cummins US headquarters. Ignition is successful. Today, Dongfeng Tianlong's flagship with the ISZ13L engine has become the focus of the market.

Dongfeng Cummins ISZ13 engine

In 2016, it was also the tenth year of the Dongfeng Tianlong Driver Contest champion Zhou Kaisheng using the Dongfeng Cummins engine. From the beginning, it used the Dongfeng Cummins Machinery large pump. For today's ISZ 13-litre fully electronically controlled engine, Zhou Kaisheng is an old Hong Kong engine user. The right to say.

On February 19, 2016, Zhou Kaisheng's Tianlong flagship began its first run after the Spring Festival. From Chengdu to Guangzhou, it took 28 hours. The first step was to express the SF Express for express delivery. The power matching is all ISZ 13-liter engine. The reporter also experienced the “first run of the New Year” with the car.

When he talked about “Dragon Brothers” Kaisheng Zhou, he felt that he was “exaggerated” and would be an extroverted personality, but in reality his character was very calm, easy-going, and not much talkative. The engine feels a bit like the ISZ 13-liter engine and is capable but not unassuming.

Discharging goods in Guangzhou, to Jiangmen loading, cargo shortage but also go to Foshan replenishment, go back for express delivery express, from Guangzhou to Jiangmen all the way driving more than four hours, for a 16.5 container truck, this paragraph is The high speed may not be the norm. The roads are narrow in some areas, there are many turns, and the cars on the road are numerous and fast, and they need to maintain sufficient attention. I sat in the back row and watched the instrument panel of Master Zhou from time to time. The speed was very stable. It was maintained at around 80km/h. It was very eye-catching at overspeed. The maximum output torque of the Dongfeng Cummins ISZ13L engine reached 2508N·m, and the torque reserve factor As much as 40% or more, it can provide enough power to support, speed up, strong explosive power, which is the general passenger car can not be compared.

It is understood that at the beginning of research and development, the Dongfeng Cummins ISZ 13L engine power from 400 horsepower to 550 horsepower, in the core technology world-class level: in terms of emissions, it uses Cummins emission treatment system (CES) selective catalytic reduction Technology not only satisfies the country's four emissions, but also has the ability to smoothly upgrade the regulations of China Five and the US EPA 2010 and above. Its backward extension can greatly reduce the subsequent upgrade cost of the entire vehicle manufacturer.

From Chengdu to Guangzhou, the total length of driving is more than 1800 kilometers. The road conditions in Sichuan and Chongqing are relatively complicated. There are more steep slopes and steep slopes. The performance of this section is the most tested engine. Zhou Kaisheng stated: Dongfeng Cummins ISZ13L engine is uphill. At the same time, it does not feel difficult, it feels similar to the flat road, and the power output is stable; when it goes downhill, the engine brake is turned on, and there is sufficient torque to control the speed. It is safe to do whatever you like. At present, the engine has been operating for 4 months, with a total mileage of more than 80,000 kilometers, and the engine has performed well. Currently, Zhou Kaisheng’s vehicle has a fuel consumption of approximately 35 liters per 100 kilometers and is 28L without load. This is still quite fuel-efficient in the express delivery industry.

In fact, from the very beginning with the Dongfeng Cummins engine until now, Zhou Kaisheng is most satisfied with the details of the engine. He told me that the engine that was used previously used oil for a period of time and could not figure out where it was leaking. He loved cleanliness and made him very annoyed. After using the Dongfeng Cummins Engine, both the large mechanical pump and the now electronically controlled engine have good sealability and are always clean. "Details determine the success or failure, and the details will be done to win more users.

The meeting is still beautiful and short-lived. Although not long with Zhou Kaisheng, there is a real truckman's shadow on him. He is practical, earnest, and diligent. This is a character he has cultivated for many years in a truck driving career. respect. Kai Sheng respectively said that he has been using the Cummins engine for many years and feels like a partner. The performance of Concord has never let him down. ISZ is also like this. Follow-up he looks forward to the next decade and even longer for Concord. Time peers.
