Mute effect is better than the standard 10% Nissan ZD30 engine hot trend has been set
According to field engineers, the ZD 30 engine is derived from the NISSAN global unified diesel engine platform. The products are launched simultaneously in multiple countries. The entire machine is exported in many countries and parts are shared globally. And the engine passed the 12,000 hours of reliability test, 100,000 kilometers of durability test and "high temperature, cold, high altitude, high humidity" calibration, can start smoothly at minus 40 degrees.
Nissan ZD 30 engine
Mute effect is better than national standards by more than 10%
After preparing the reporter to enter the professional test site, began to experience the actual engine. After starting the engine into the idling state, the reporter's maximum feeling in the cab can only be described in two words - quiet. In the process of engine idling, there is no incidental noise in the cab except for a small speed sound. The actual operating noise measured in the cab is around 90dB, which is better than the national standard of more than 10%.
When a reporter asked why the engine was working so quiet, the technical engineer sitting in the co-pilot said: “Noise reduction is a major highlight of the ZD 30 engine. This engine uses a silent transmission that can automatically adjust the degree of tension. The chain has less noise than the timing belt drive.At the same time, the engine also reduces the mechanical hard links such as the push rod and the tappet, thus reducing the noise of the engine's transmission.Compared with the engine of the same class, the noise treatment of the ZD 30 engine has Absolute advantage."
"In addition, the silent maintenance-free chain has a more accurate gas distribution than a conventional toothed rubber belt, and it is maintenance-free all the time. It has certain advantages in terms of maintenance costs," said the technical engineer.
Strong power output stability
At the same time as the introduction of the technical engineer, the reporter has begun to drive to the three test sections of the Pebble Road, the Yongban Road, and the slope road. After explaining the principle of noise reduction of the engine, the technical engineer introduced the power parameters for the reporter. “The ZD 30 engine can reach a maximum of 150 horsepower and the maximum torque is 370N.m.†After the voice does not drop, the reporter has already driven into the pebble section. In high-frequency bumpy road conditions, the reporter noticed that the ZD 30 engine was not affected and the power output was still smooth.
After the smooth passage of the cobblestone road, the ZD 30 engine still did not disappoint the reporter in the face of major obstacles, and the stability of the engine was excellent at one go.
As we all know, the uphill section is the key to testing engine power. When the reporter passed the uphill section, he remained in the third gear, the power output of the engine was very stable, and there was no sense of frustration in the entire uphill process, and the engine was full of stamina.
When talking with the technical engineer during the uphill course, the reporter learned the reason for the engine's stability. The technical engineer told the reporter: "The ZD 30 engine uses BOSCH's new electronically controlled high pressure common rail fuel injection system. The injection pressure is between 1600 bar and 2600 bar. The high pressure makes the effect of atomizing spray better and the piston work more stable. So the engine Power output is smooth."
Fuel-saving brother also thumbs up on it
The technical engineer told the reporter on the way to the reporter’s return to the starting point: “The ZD 30 engine is not only powerful but also very fuel-efficient. The common rail injection system used in the engine can adjust fuel injection timing and injection timing at any time to ensure The fuel efficiency is good, the minimum fuel consumption rate is 210g/kW.h, which is far less than the average diesel engine 240g/kW.h. The performance of 100km fuel economy is particularly prominent.
The First "Finding the Fuel One" Challenger Pan Tanbo
After the actual experience was over, the reporter met Pan Tanbo, the champion of the first "Finding a Fuel-Saving Challenger" at the scene. Pan Tanbo told reporters: "I am now doing home appliance distribution in Changsha. I'm opening Dongfeng Kapit. The ZD 30 engine, according to our team's driver feedback, this engine is very good fuel economy, the actual transportation process is about 0.7 yuan per kilometer fuel consumption, while other models are at 0.9 yuan, a year down every car in the fuel Saving thousands of pieces is not a problem."
China Truck Network also learned from the technical engineer that the ZD 30 engine has successfully achieved the national IV and the national 5 emission standards in China, and Europe can also meet the EU 6 emission regulations. In addition, the ZD 30 engine will be fitted to the full range of Capt. and Dolly trucks. Pan Tanbo is also very much looking forward to this: "In the process of urban logistics and transportation, the comfort of the vehicle is particularly important to the driver. Thus, a stable engine with good power output and good performance in fuel economy and noise reduction will definitely be deep. Favored by users"
