How long do bus diesel engines last?


How long do bus diesel engines last? Over the long haul, newer diesel engines will last 15-20 years in a fleet, while a gasoline engine may need to be replaced once or even twice during the life of a school bus. “All of these are important for fleet managers to stop and consider when choosing a new school bus,” says Hedgecock.


Do diesel engines really last longer?

The two technologies are similar, but differences in design mean that diesel engines are built tougher and last longer. This is true for all types of passenger cars, trucks, commercial vehicles and other diesel-powered equipment. Like all engines, diesels only last a long time if they're looked after properly.


What is the range of a diesel bus?

Battery-charged vehicles typically have a driving range of 70-100 miles, and some can go up to 265 miles before needing to be recharged (diesel buses have an average range of 690 miles).


What is the most fuel efficient school bus?

Diesel school buses are already the most fuel-efficient in the industry, due to a higher BTU count compared to other fuels, providing better fuel economy and a longer operating range compared to similar-sized gasoline, propane or compressed natural gas (CNG) engines.


Are bus engines reliable?

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.


How big is a bus fuel tank?

The tanks on gas buses are usually either 30 or 60 gallons.


How many miles per gallon does a Coach bus get?

Motorcoaches move people with little fuel. The average fuel efficiency of a motorcoach is 6.1 miles per gallon of fuel. With this fuel efficiency, a motorcoach carrying the industry average of 36 passengers achieved 240 passenger miles per gallon of fuel.


What is the lifespan of a bus engine?

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 is the lifespan of a diesel bus?

This timeframe matches a diesel school bus, which has an average lifespan of 12 – 15 years as well.


What is the most common bus engine?

Propulsion. The most common power source since the 1920s has been the diesel engine. Early buses, known as trolleybuses, were powered by electricity supplied from overhead lines.


What is the most efficient bus engine?

Period. Why? Diesel is the most fuel-efficient engine type on the market. Diesel outperforms other fuels in operating range.


How many miles per gallon does a diesel bus get?

Most of those buses get between 6 and 9 miles per gallon. Thats about the standard for 5.9 to 8.2 Liter diesel engines. Mileage for busses is impacted by the start and stop nature of their use. Mileage for similar engines in over-the-road buses and motor homes will average a few miles per gallon more.
