This is a picture of the engine compartment of my TMC T80206 bus conversion.
My RTS has a Detroit Diesel Series 50 four cylinder diesel engine. The drive shaft is parallel to the bumper, and the automatic transmission is barely visible in the lower right of the picture.
The 260 amp 24 volt alternator is the large gray component in the upper left of the picture. One day that alternator will power my Trace SW4024 inverter and charge the ‘house’ batteries.
My engine has about 368,000 miles on it, but these engines are known as million mile engines, so with proper care, I’ll never wear it out from driving.
The engine displaces 8.5 liters and produces 275 horsepower at 2100 RPM. This is enough to cruise all day at 75 miles per hour, and to go 50 miles an hour up the Marin side approach to the San Francisco Golden Gate Bridge. That might not seem fast, but less capable engines might only push a vehicle this size up that incline at 30 miles per hour. I was smiling when I first learned I could go 50 miles an hour up a long hill.
275 horsepower might not seem like much, but the torque this engine produces dwarfs that from an engine in a pickup truck, which is why this engine can propel a vehicle that weighs nearly 14 tons with relative ease.
I get 10.75 miles to the US gallon of diesel on the freeway with my bus conversion, which, on a per pound basis, is much better than a Toyota Prius gas-electric hybrid automobile, popular in the United States.
