DISADVANTAGES OF THE 4JB1 ENGINE

While the Isuzu 4JB1 engine, including its Komotashi-branded version, is known for its reliability and performance, it has some disadvantages that should be considered:

Noise and Vibration:
- Diesel engines, including the 4JB1, tend to be noisier and produce more vibrations compared to gasoline engines. This can be a drawback in applications where noise levels are a concern.
Weight:
- Diesel engines are generally heavier than their gasoline counterparts. The 4JB1 is no exception, which can impact the overall weight of the vehicle or machinery, potentially affecting performance and fuel efficiency.
