Special design for special car accurately adapts to Isuzu NPR/NQR models

Behind every Isuzu NPR/NQR truck, there is a powerful power system to provide a steady stream of energy. In the entire engine structure, this 4HE1 crankshaft plays a key role. After rigorous design and many field tests, it fully conforms to the original technical specifications and can maintain stable operation under various complex driving conditions. The unique geometric contour and precise assembly interface make the installation easier and faster, and greatly improve the working efficiency of the whole machine.

Solid guarantee for long-term wear resistance of high-strength alloy steel casting

As the core bridge connecting piston movement and transmission, this 4HE1 crankshaft must withstand frequent reciprocating impact. Therefore, we are made of high-quality alloy steel, which has extremely high tensile strength and fatigue resistance. Even in the long-term continuous high-pressure working state can also ensure that the structural integrity is not damaged. In addition, the special surface hardening process further enhances its fighting ability and long-term reliability, which can be easily controlled whether it is short-distance city distribution or inter-provincial long-distance transportation.

Precision manufacturing process ensures stable and reliable start-up every time

In order to meet the requirements of modern commercial fleets for low failure rate and high maintenance cycle, we have introduced automatic CNC CNC machine tools for fine grinding and polishing in the production process. All key parts such as main journals and connecting rod shaft diameters have reached the consistency standard within the micron error range, thereby reducing friction loss and improving rotation smoothness. Strict quality control system runs through the whole process of raw material screening to finished product delivery, ensuring that every crankshaft delivered to customers is a precision work.

Competency for multiple application scenarios Strong power continuous output

whether it is shuttling goods through crowded city streets, climbing mountains to carry out arduous tasks, or Mercedes-Benz completing its trunk logistics mission in major highway networks across the country, this high-performance 4HE1 crankshaft can show satisfactory overall performance. The balanced power distribution mechanism and excellent thermal stability characteristics make it still play normal performance in the environment of severe temperature changes, and also help to improve the level of fuel consumption and thus enhance economic benefits.

Maintenance and upgrading are suitable to realize the sustainable development of the vehicle power system

Over time, some vehicles that have been in service for many years may face the problem of aging or even damage of parts. At this time, replacing a new high-quality 4HE1 crankshaft can quickly restore the original strong and powerful state. For those who pursue stronger horsepower output, it can well undertake the additional pressure load brought by a series of subsequent modification projects, such as turbocharger installation, camshaft adjustment and other operations can be well coordinated with it. In this way, the old car can also be rejuvenated and continue to gallop.
