There is a growing awareness of the need to care for the environment, which is why emission standards for diesel engines are being established. These standards are implemented by the United States Environmental Protection Agency (EPA) and are also applied in other countries or regions under similar names, such as Europe.
Here are some of the most common Tier 4 (in Europe “Stage IV”) compliant industrial engines from brands such as John Deere and Yanmar.
6090 JOHN DEERE
The John Deere 6090 engine is an in-line 6-cylinder PowerTech series diesel engine with a displacement of around 9.0 liters. It achieves a power output ranging from 150 to more than 300 horsepower (HP).
This engine is in agricultural tractors, harvesters, forestry machines…
4TNV98C AND 4TNV98CT YANMAR
The 4TNV98C is an in-line 4-cylinder diesel engine with a displacement of approximately 3.319 liters. It can offer a variety of power outputs depending on the specific application and configuration, but is generally in the range of 45 to 66 horsepower (HP). In addition, it uses a direct fuel injection system that allows for better combustion efficiency and reduced emissions.
This engine is applied in machines such as harvesters, excavators, mini loaders…
In addition, another Yanmar engine with these characteristics is the 4TNV98CT. Both engines have similarities and differ in that the 4TNV98CT engine is turbocharged, i.e. it uses a supercharging system to increase the amount of air entering the engine, resulting in improved engine performance and power.
ENGINES IN COMMON
John Deere and Yanmar share a partnership in the design and manufacture of certain engines. This collaboration has led to the production of certain engine models that are marketed under both brands. These shared engines are in a variety of equipment, such as compact tractors, compact excavators, agricultural and industrial equipment. The table below shows which engines John Deere and Yanmar have in common:
