Difference Between Diesel Generator and Gasoline Generator
by Starlight Generator dieselgeneratortechWorking principle of diesel generator
In the cylinder of the diesel
engine, the clean air filtered by the air filter is fully mixed with the high
pressure atomized diesel fuel injected from the injector. Under the upward
extrusion of the piston, the volume is reduced and the temperature is rapidly
increased to reach the ignition point of the diesel. The diesel is ignited, the
mixed gas burns violently, the volume expands rapidly, and the piston is pushed
down, which is called work. Each cylinder performs work in a certain order, and
the thrust acting on the piston passes through the connecting rod to become a
force that pushes the crankshaft to rotate, thereby driving the crankshaft to
rotate.
Working
principle of gasoline generator
In the cylinder of the gasoline
engine, the mixed gas burns violently, and the volume expands rapidly pushing
the piston to work downward. Each cylinder performs work in a certain order,
and the thrust acting on the piston passes through the connecting rod to become
a force that pushes the crankshaft to rotate, thereby driving the crankshaft to
rotate. By installing the brushless synchronous alternator coaxially with the
gasoline engine crankshaft, the rotor of the generator can be driven by the
rotation of the gasoline engine. By using the principle of
"electromagnetic induction", the generator will output an induced
electromotive force, and a current can be generated through the closed load
circuit. .
It can be seen from the above
that in the diesel engine, the mixture is compressed into heat, and the mixing
of fuel and air in the cylinder of the gasoline engine is marked with a spark
plug; diesel is less volatile than gasoline, and has a larger gallon per
gallon. The calorific value, that is, 5dm3 diesel can obtain more power than
5dm3 gasoline; in the diesel engine, the mixture of diesel and air is carried
out after the diesel is injected into the cylinder, while in the gasoline
engine, the fuel and air are in the carburetor and the intake Mixed in the
pipeline. Since the mixing must be immediately after the fuel eruption, the
diesel generator needs to have a specially planned combustion chamber to
facilitate the mixing of diesel and air. Therefore, the planning and production
of the combustion chamber is very important for diesel generators.
The
difference between diesel generator sets and gasoline generators
The difference between a diesel
generator set and a gasoline generator set is mainly due to the different
performance of its diesel engine and gasoline engine.
1. The type
of fuel
Diesel is a fuel that is less
volatile than gasoline, and has a large calorific value per liter of diesel.
2. The type
of ignition
In the cylinder of a gasoline
engine, a mixture of fuel and air is ignited with a spark plug. In a diesel
engine, the mixture is ignited by the heat generated by compression.
3. Mixing of
fuel and air.
In a gasoline engine, fuel and
air are mixed in a carburetor and an intake duct. In a diesel engine, the
mixing of fuel and air is performed after the diesel is drawn into the
cylinder.
4. The output power of a diesel
generator is much larger than the output power of a gasoline generator. The
average power of a typical gasoline generator is only 10KW, while the
minimum power of a diesel generator set is 8KW.
5. Gasoline
generators are small in size.
The movement is convenient, and
the diesel generator set is bulky and inconvenient to move.
What are the advantages of diesel
generator sets compared to gasoline generator?
There are many models in the
generator set, and the power is different. Most of the large and medium-sized
generator sets are fueled by diesel. The generators with smaller power are
generally fueled by gasoline. So what are the advantages of a diesel generator
set with a diesel engine and a gasoline generator with a gasoline engine as
a generator power source?
1. Fuel
consumption
The diesel engine has high
thermal efficiency, low fuel consumption rate, and the fuel pump rate curve
changes relatively flat when the working conditions change, which is very
important for diesel engines that often work under partial load.
2. Reliable
and durable work
Since there is no ignition system
the diesel engine, the fault is relatively small and the work reliability is
high.
3. Wide range of use
4. Lees harmful emissions
5. Good fire safety
