How long do school bus engines last?
Some alternatively fueled engines like propane or gasoline may need to be replaced two to three times during the normal lifecycle of a school bus. Clean-diesel engines, on the other hand, are built to last 15-20 years. The difference in engine life lies in how engines are built.
Do school buses have two engines?
There are two typical school bus placements for the engine – “rear engine (RE)” or “front engine (FR).” When buying a school bus, the engine location is a primary factor to consider. A front engine has the center of the bus mostly occupied, but there is no block with a rear engine.
Why are used school buses so cheap?
Prices of Used Buses
One reason why used buses are so cheap is that they may not meet government regulations (discussed below) and thus cannot be purchased by government agencies. Another reason why they are so cheap is that many of them are just purchased for parts.
What happens if you put a bus engine in a car?
Putting one in a car will make the vehicle overweight and not as fast as a car with a high output car engine. Unless you’re referring to super duty or semi trucks, most manufacturers DO put their truck engines into cars. With the exception of most diesels.
What engine is in a bus?
Some of the city buses are diesel electric, it runs a generator that drives the wheels. Like a lot of huge mining equipment, they used to run on steam. They have steam engines 150 years old, still going. But they use coal to run, so that’s a problem.
Do buses have Turbo?
Buses and trucks generally use a 6 cylinder in-line diesel engine and using a turbocharger can improve the thermal efficiency of the engine and also can control the emission level to an extent. Though old buses are not equipped with turbocharger the buses manufactured nowadays are fitted with a turbocharger.
What color were school buses before they were yellow?
It’s also a matter of safety. Federal law in the United States requires that, in addition to flashing lights and safety devices, school buses must be painted “school bus yellow.” Before the standard school bus yellow color was developed, school buses were a pure yellow, closer to the color of a lemon.
Why are some school buses flat in the front?
The driver is in a low position allowing passengers to look out of the front end above the driver. This coach is more aerodynamic than the city bus seen above: The corners are more rounded and the upper part of the front window is sloping back. So the shape of a bus/coach depends on its purpose.
