The fuel consumption of diesel locomotive is generally said to be full load fuel consumption and average fuel consumption of each cycle, and the unit is g/kWh. For example, the full load fuel consumption of dongfeng 4D type is 198g/kWh, so we calculate it according to 100km/h speed and 2800kW power, and the fuel consumption per 100km is 554.4kg, which is 668 liters according to the density of diesel 0.83. In fact, more than that, the average diesel locomotive has 9-10 tons of fuel tanks and can only run more than 1,000 kilometers. Now railway passenger transportation is not a car ran to into several segments, points to several car to complete the entire journey ` ` so the road is a ` don't have to go

Generally in the depot refueling, because there is an oil depot. Under special circumstances also through the tanker refueling.

Generally from already this section refuels, the long cross road locomotive also has the outside section refuels.

The fuel tank sizes of locomotives vary, for example, 4B has a capacity of 9000L, and quasi-high-speed 4D has a capacity of 6500L.
