Özet

Garbage trucks are primarily used within urban environments. In the context

of urban usage, electric garbage trucks offer numerous advantages over those equipped

with internal combustion engines. Foremost among these advantages is the absence of

carbon emissions. Consequently, this represents a significant step toward improving air

quality and controlling global warming. Additionally, the operation of electric vehicles is

notably quieter, playing a crucial role in reducing noise pollution in cities. The advantages

presented by electric systems enable garbage collection activities to be carried out during

early morning hours and late at night. Traditional garbage trucks require extensive

maintenance due to their daily use. However, the fewer components and simpler

mechanical structure of electric vehicles result in a significantly lower maintenance

requirement for system components. This reduces maintenance and operating costs and

increases the time the vehicle can be actively working. Since electric garbage trucks

require electric energy for all their operations, they can be charged with electricity

generated from renewable energy sources, thereby minimizing dependency on fossil

fuels. During their driving cycles, garbage trucks operate at very low speeds and must

frequently stop and go. Research indicates that, depending on the city in which they are

used, the average vehicle speed during the driving cycle of garbage trucks ranges between

5 km/h and 20 km/h (Derakhshan, 2019). The garbage truck with an internal combustion

engine operates in the most inefficient region of the driving cycle, which corresponds to

the range where the engine efficiency is 5%-15% (Ehsani et al., 2018). The efficiency of

electric motors is much higher than internal combustion engines. The electric motor does

not consume energy while the vehicle is stopped. In this way, in frequent stop-and-go

scenarios, the electric vehicle has much higher energy efficiency than the vehicle with

internal combustion engine. When the same driving cycle is applied to an electric vehicle,

the efficiency is determined to be 65%-75% (Ehsani et al., 2018, Olszowiec, 2021). As a

result of the calculations made within the scope of this study, the vehicle with internal

combustion engine consumes 3 times more energy than the electric vehicle during the

garbage truck driving cycle.
