* Engine Size: Bus engines vary greatly in size, from smaller diesel engines in smaller buses to massive, powerful engines in large coaches or articulated buses.
* Type of Engine: Different types of engines (diesel, gasoline, electric) will have varying weights.
* Manufacturer: Different manufacturers design engines with varying weights.
* Specific Model: Even within a manufacturer's lineup, different engine models will have different weights.
However, here's a general range:
* Small bus engines: Could weigh around 1,000-2,000 pounds (450-900 kg)
* Large coach engines: Might weigh 3,000-5,000 pounds (1,350-2,250 kg) or more.
To get a more accurate weight for a specific bus engine, you'd need to look up the engine's specifications from the manufacturer.
