- Cooling System
- Electrical System
1.3 Types of Garbage Truck Engines
Garbage trucks typically feature diesel engines due to their durability and efficiency. However, there are other alternatives such as compressed natural gas (CNG) engines and electric engines emerging in the market.
1.3.1 Diesel Engines
Diesel engines remain the most common choice for garbage trucks because of their high torque output and fuel efficiency. They perform well under heavy loads, making them ideal for waste collection.
1.3.2 Compressed Natural Gas Engines
CNG engines are becoming increasingly popular as a cleaner alternative to diesel. They produce fewer emissions and contribute to a reduced carbon footprint.
1.3.3 Electric Engines
Electric garbage trucks are still in the early stages of adoption, but they offer a sustainable option for urban waste collection, producing zero tailpipe emissions.
2. Garbage Truck Engine Specifications
2.1 Engine Size and Power
The size and power of a garbage truck engine can vary significantly based on the truck’s design and intended usage. Most garbage truck engines range from 5.9 liters to over 12 liters, producing anywhere from 200 to 500 horsepower.
2.2 Torque Output
Torque is a critical factor in garbage truck engines because their primary function is to move heavy loads. High torque facilitates effective hauling capacity. Most engines have a torque output between 500 to 700 lb-ft.
2.3 Fuel Economy
Fuel efficiency is vital for operational cost management in waste collection. Diesel garbage trucks typically offer a fuel economy of 6 to 8 miles per gallon, while CNG engines may have slightly lower efficiency.
| Engine Type | Horsepower | Torque (lb-ft) | Fuel Economy (mpg) |
|---|---|---|---|
| Diesel | 300 – 500 | 500 – 700 | 6 – 8 |
| CNG | 200 – 350 | 400 – 600 | 5 – 7 |
| Electric | Varies | N/A | N/A |
