The importance of high-performance crankshafts

As one of the core components of the engine, the performance of the crankshaft directly affects the power output and operating stability of the vehicle. The high-quality crankshaft can ensure the efficient operation of the engine under various working conditions, reduce the occurrence of failures, and extend the life of the engine.

Core components of the engine

The crankshaft is located inside the engine, connecting the piston and the connecting rod, and converts the reciprocating linear motion of the piston into rotary motion through rotation, thereby driving the car forward. Therefore, the quality and performance of the crankshaft is very important.

The working principle of crankshaft

When the fuel is burned in the cylinder, the generated high-pressure gas pushes the piston down, and the piston drives the crankshaft to rotate through the connecting rod. In this process, the crankshaft needs to withstand huge pressure and friction, so it must have extremely high strength and wear resistance.

Why choose 4HE1 crankshaft

Since the launch of the 4HE1 crankshaft, it has won the trust of the majority of users. Here are a few of the main reasons for choosing a 4HE1 crankshaft:

The choice of trust for more than 40 years

4HE1 crankshaft has been used in Isuzu NPR/NQR models since the 1970 s and has a history of more than 40 years. During this time, it has been widely recognized in the market for its excellent performance and reliability.

Adapt to multiple working conditions

Whether it is urban distribution, long-distance freight or special operations, the 4HE1 crankshaft can easily handle it, ensuring that the engine works stably in various complex environments.

Technical highlights of 4HE1 crankshaft
