Yanmar 4TNV94L Engine
The Yanmar 4TNV94L engine is a diesel engine suitable for small mechanical equipment. It is developed and produced by the Japanese Yanmar Company. The engine uses four-stroke, four-cylinder, turbocharging and intercooling technology, and has the characteristics of low fuel consumption, low emissions and low noise.
Plunger pump
The plunger pump selected for the 8-ton small excavator has the following six advantages:
1. High parameters: high rated pressure, high speed, high pump driving power
2. High efficiency, volumetric efficiency is about 95%, and total efficiency is about 90%
3. Long life
4. Convenient variables and many forms
5. Light weight per unit power
6. The main parts of the plunger pump are all subject to compressive stress, and the material strength properties can be fully utilized.

Hydraulic oil cooler
The hydraulic oil radiator is an indispensable heat dissipation device in the hydraulic system. The excavator hydraulic system needs to dissipate heat of the hydraulic oil through the radiator to maintain stable oil temperature and protect the normal operation of the hydraulic system.
