The "Diesel Age" refers to the period marked by the widespread use of diesel engines in various industries, particularly in transportation and manufacturing. This era began in the early 20th century when Rudolf Diesel invented the diesel engine, which offered greater efficiency and power compared to steam engines and gasoline engines. Diesel engines became popular in trucks, ships, and trains due to their ability to run on heavier fuels and their durability. As the Diesel Age progressed, it significantly impacted global trade and logistics. The increased efficiency of diesel-powered vehicles allowed for faster and more reliable transportation of goods. Additionally, the rise of diesel locomotives transformed rail transport, making it a vital component of the economy. Today, diesel technology continues to evolve, focusing on reducing emissions and improving fuel efficiency.
