Dieselkjøretøy refers to vehicles powered by a diesel engine. These engines operate on the principle of compression ignition, where the fuel is ignited by the high temperature generated by compressing air within the cylinder, rather than by a spark plug as in gasoline engines. Diesel engines are known for their high torque output, fuel efficiency, and durability, making them a popular choice for heavy-duty applications like trucks, buses, and agricultural machinery, as well as for passenger cars.

The development of diesel engines dates back to the late 19th century, with Rudolf Diesel patenting his engine design in 1892. Early diesel engines were bulky and noisy, but technological advancements have led to more refined, powerful, and cleaner-running engines. Modern diesel vehicles often incorporate advanced emission control systems, such as diesel particulate filters (DPFs) and selective catalytic reduction (SCR) systems, to reduce harmful pollutants like nitrogen oxides (NOx) and particulate matter.

Despite their advantages in fuel economy and torque, diesel engines have faced increasing scrutiny due to their emissions. Regulations in many countries have become stricter, prompting manufacturers to invest heavily in cleaner diesel technology and, in some cases, to shift towards alternative powertrains like electric or hybrid systems. The perception of diesel emissions has also led to a decline in their popularity in some consumer markets, although they remain a vital part of the transportation and logistics sectors.
