China manufactures and assembles the ISF2.8. The ISF2.8 engine, according to Cummins, can last for up to 500,000 kilometres (300,000 miles).

However, this engine’s low-quality assembly and materials have given it a terrible reputation in the Asian market.

In this engine, cylinder wall wear is the leading cause of failure. This led to a rise in the demand for oil. Weak connecting rod bearings can lead to crankshaft failure, which is the next issue to be addressed.

As an added downside, the engine heats up quickly. The intrusion of cooling liquid into cylinders is a major safety concern.

The examples are endless. Depending on tweaks, the ISF 2.8 engine complies with Euro 3, and Euro 4 pollution requirements.

The R2.8 is produced in Cummins’ Columbus, Indiana factory (500 engines in 2017) and comes with a short 3-month guarantee.
