Advantages of diesel engines over gasoline engines

The main advantage of diesel engines over gasoline engines is the lower running costs. For example, lower fuel consumption and maintenance costs, longer maintenance intervals (5000 hours). In this article, JUNVOCH, a professional diesel generator set manufacturer, will give you examples to illustrate the advantages and disadvantages of the two.


Taking the 5000W generator set as an example, the economic comparison between diesel generator set and gasoline generator set is as follows:


5000 Watt gasoline engine set


5000 Watt diesel engine set


fuel consumption per hour


3.4L/h


2.39L/h


Average price per liter (RMB (Yuan))​


6.53


6.39


Cost per hour (yuan)


22.2


15.3


Diesel units save hourly costs over gasoline units


3500


5600


Therefore, it only takes about 305 hours to earn back the extra cost of purchasing a 5000W diesel generator set compared to purchasing a 5000W gasoline generator set. With an average daily use of 3 hours, it will take about 4 months. In summary, the scope of application of gasoline engines and diesel engines is as follows:
