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:
Engine
Scope of application
Gasoline engine
Suitable for a wide range of applications, with operator comfort and durability in mind.
Diesel engine
It is suitable for many use occasions and has long-term economy.
