dízelbusz

A dízelbusz, or diesel bus, is a type of bus that is powered by a diesel engine. Diesel engines are internal combustion engines that operate by igniting diesel fuel through compression. They are known for their fuel efficiency and torque, making them suitable for heavy-duty applications like buses.

The first diesel-powered buses appeared in the early 20th century, following the development of reliable diesel engines. These early models gradually replaced gasoline-powered and electric trolleybuses due to their longer range and greater operational flexibility. Diesel buses became the dominant form of public bus transportation in many parts of the world throughout the mid to late 20th century.

Modern diesel buses incorporate advanced technologies to reduce emissions and improve performance. These include turbocharging, direct injection, and exhaust after-treatment systems such as diesel particulate filters (DPFs) and selective catalytic reduction (SCR) systems. These technologies help meet increasingly stringent environmental regulations concerning air quality.

Despite the rise of alternative powertrains like electric and hybrid buses, diesel buses remain prevalent due to their established infrastructure, lower initial cost, and proven reliability, especially in regions where charging infrastructure is limited or where long-distance routes are common. However, ongoing efforts are focused on developing more sustainable and environmentally friendly public transport solutions.
