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.
What kind of engine do school busses have?
Diesel engines are built to last and are specifically designed for medium-duty use. Diesel engines can last 15 to 20 years or more. Diesel engines last 2-3 times longer than their propane and gasoline counterparts. Diesel engines almost never need to be replaced during the life of a school bus.
What is the most reliable school bus?
No question, the longest-lasting buses are the Crown Supercoach and the mid-engine Gillig. Rear-engine Gillig is nice too but the Cat 3208 doesn’t run as long as the Cummins/Detroit before overhaul, and I’m told some of the Cummins-powered RE’s should be avoided at all cost.
What is the fastest a school bus can go?
By law, school buses must travel “at a safe rate of speed, consistent with the volume of traffic, intersections, curves, railway crossings and any other condition requiring special caution.” The law sets the maximum speed for school buses at 50 mph on divided, limited access highways and 40 mph on all other highways, “ …
Why are gas engines better than diesel?
Essentially, diesel engines provide a better bang for your buck for the fuel put into them. A diesel engine’s high torque application is very beneficial for hauling, as it helps with carrying heavy loads. Gas engines, on the other hand, have a much higher volatility point but a lower flash point.
What is high mileage for a school bus?
These standards determine the maximum age and mileage for which a bus should be used. Smith said buses are expected to last about 12-15 years and 250,000 miles under normal conditions.
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.
How many miles is a school bus good for?
On average, a school bus will last between 12 and 15 years, with 250,000 miles to its credit. This, however, is a school bus that has performed under normal driving conditions.
What is the power of a bus engine?
When specifying engines for your buses, you will notice that the engine rating has two numbers: horsepower (200, 220, 240, 260 etc.) and torque (520, 540, 600, 660 etc.). While these are related to one another, various applications have different needs in terms of the power or torque that are required.
