To reduce fuel consumption on a diesel engine, do everything to ensure that it runs without stress, which increases fuel consumption. Check the condition of the air filter, if it is clogged, replace it. When changing oil, select grades with the lowest possible viscosity. Increase the tire pressure by 0.3 atmospheres from the norm. Watch your driving mode.
Necessary
air filter, low viscosity oil, pump
Instructions
Step 1
Remove the engine air filter and look through it at the light. If the lumen is not visible through the filter material, then it must be replaced. Install a new air filter. This will allow the engine to run more taut, at lower rpm, which will reduce fuel consumption.
Step 2
When changing oil on a diesel engine, select the lowest viscosity grade possible. Their use will allow the engine to work more freely, which will significantly reduce the consumption of fuel consumed. In this case, the oil must be of high quality, otherwise the engine will quickly fail. These two simple steps can save up to 10% diesel fuel.
Step 3
Inflate the tires slightly to reduce the rolling resistance of the vehicle. Find out what pressure is recommended in the tires used on the car and increase it by 0.3 atmospheres. Rolling resistance will be significantly reduced, and with it fuel consumption. This method has a significant drawback - over-inflated tires become too stiff and all road irregularities inflict a hard blow on the suspension. As a result, its service life is reduced.
Step 4
Choose a relaxed riding style. The revolutions of a diesel engine when driving in any gear should be no more than 2000 revolutions per minute, and it is better that they generally be within 1500 revolutions. Increase the gear after cranking the engine no higher than 2500 rpm, otherwise excessive fuel is consumed. But keep in mind that when driving at too low rpm, the load on the engine increases.
Step 5
If the diesel engine is equipped with a turbine, do not allow it to actively pump up the cylinders, which will sharply increase fuel consumption. If the goal is to drastically reduce consumption, turn it off altogether if the engine design allows it. But this will significantly reduce engine thrust.
