Choice of engine type

All gasoline generators are equipped with internal combustion engines. According to the principle of operation, they are divided into four and two-stroke.

For weak petrol generators with maximum power up to 5 kW a two-stroke motor is installed. The motor in this version is very easy to start even at fairly low temperatures. Such a motor will consume much less fuel and is easy to operate.

A four-stroke engine is used for devices that are designed for long-term operation (from 5 hours) without interruption. It is more powerful and does not require the preparation of various oil mixtures. Its biggest disadvantage is that it is difficult to start at subzero temperatures, and sometimes, in general, refuses.

We watch the video, the criteria for choosing a generator:

Before deciding which gas generator to buy, you need to understand that engines also differ in the number of cylinders, the materials from which they are made, as well as the principle of valve placement. The most unstable are aluminum cylinders. In addition, they have very little working time. Cylinders of this kind are installed on small mini power plants, which are used for outings, fishing, tourism, hunting, etc. places where mobility, compactness and light weight are required.

More expensive, powerful and heavy are cast-iron engines with side-mounted valves. Models of this type are used to supply electricity to small country houses with low power consumption. So that the question does not arise, which gas generator better suited for home, we advise you to choose this particular option for seasonal use throughout the entire holiday with temporary interruptions in the main supply of electricity. In addition to purchasing for backup power at summer cottages, they are used for road construction needs, resource extraction and in the field.

Model with a four-stroke engine and cast iron cylinders

The most productive and powerful units of an expensive price category are equipped with a four-stroke engine and cast-iron cylinders. The valves are located at the top. Their service life exceeds 3000 hours, which is very close to diesel stations.

Models of this kind are installed to provide cottages and country houses with electricity during a seasonal holiday or a whole year.With which engine it is better to buy a gas generator, questions should not arise, we move on.

Scope of application of single-phase and three-phase

Single-phase devices are designed to provide electricity to a 220 volt network. Three-phase power supplies two types of electrical appliances: 220 (single-phase) and 380 (three-phase) volts. At first glance, it may seem that three-phase generators are more versatile and therefore more preferable, but this is not the case. The number of phases is the type of connection, but not an indicator of the power and "reserve" of the generated electricity.

Single-phase power plants (220 V) are intended for use in the following areas:

Summer cottages, country and private houses, as a backup and permanent source of electricity. In this case, the device should be selected according to the criteria for the expected power consumption. The average level of consumption is provided by generators with a capacity of up to 3 kW; in the presence of a larger number of electrical appliances - up to 10 kW

The line of single-phase models is very wide, there are those that independently control the stability of the supply of electricity from the general network and, at the slightest failure and shutdown, turn on automatically, which is very important if there are computer equipment and gas equipment with automation in the house. Medical and educational institutions, offices, offices, checkpoints, etc.

Autonomous power plants capacity from 7 to 10 kW are capable of providing the simultaneous operation of a TV, computer, refrigerator, heaters, boiler, lighting lamps. Industrial enterprises, construction sites, laboratories, shops - provided that the type of connection of devices there is 220 volts. Models of single-phase generators with high power easily meet all the needs of such areas.

Advantages of single-phase power plants: price, ease of connection and maintenance, savings in fuel and lubricants.

There is only one drawback - the ability to connect only single-phase devices.

Three-phase gas generators are intended for use in those areas where devices with this type of connection are used. In the overwhelming majority of cases, this, of course, is industry, construction sites, but in everyday life it is not so rare to find water pumps and washing / dishwashers with a three-phase connection, not to mention welding machines, concrete mixers, perforators, which are used for repair and improvement. household owners of their home. Three-phase stations are selected in the same way according to the criteria for the power of the expected consumption.

Important: you should not buy a three-phase gas generator if there are no devices operating from a 380 volt network. Disadvantages of three-phase generators: high price, large weight and volumes, complex connection, excessive consumption of fuel and lubricants and the impossibility of removing full power when operating in the mode of a single-phase generator

Disadvantages of three-phase generators: high price, large weight and volumes, complicated connection, excessive consumption of fuels and lubricants and the impossibility of removing the full power when operating in a single-phase generator mode.

There is only one advantage: the ability to connect devices for 220 and 380 volts.

Operating tips

For successful and long-term operation of the device, it is necessary to adhere to some basic recommendations

A very important component of generator efficiency is its fuel. It is not recommended to use different types of oils, as this can negatively affect the subsequent quality of parts.

It is always necessary to stir oil and gasoline in the correct proportion, which is indicated in the instructions.

Before each generator start-up, check the grounding, the correct amount of fuel, and let the engine run for a few minutes without load so that it has time to warm up. Do not forget about the various filters and candles that need to be changed after a certain period of time.

During operation, make sure that there are no various explosive substances near the generator, and the power used is not too high or too low. Also, store the machine properly and let it rest after each working period specified by the manufacturer.

Criterias of choice

For the successful selection of a suitable generator that will be used at home or summer cottages, it is preliminarily determined with the following questions:

Required power of the device. It is determined by a preliminary calculation of the expected load, which is calculated by summing the capacities of devices (up to 10 or more) that can be connected to the station at the same time.
Output voltage (220 or 380V). It is determined depending on the requirements for the equipment or tool that will power the station.
What electrical appliances will power the generator (the stability of the output parameters matters).
How often will it be operated. When using the device as a backup power source, and when working for a relatively short period of time, it is better to stop at a gas generator. A diesel device can also easily cope with this, but for short-term switching on it is less preferable.
What resource the device has. Generators with a small resource (500 hours) are lightweight, mobile and have a low price. It is quite suitable if its inclusions are short-lived. When operating the device for more than 7-10 hours, you should choose an engine with a large motor resource. Usually, for continuous operation of the device for a long time, and when sufficient power is required (more than 10 kW), a diesel generator is installed, which has a long service life, reliability, efficiency, and a stable output voltage.
How important is the noise level during the operation of the device.

If a generator is required only to compensate for the lack of light several times a year, then its purchase will not be advisable from the standpoint of cost savings. In such cases, food in a summer cottage can be cooked on a camping gas burner, the phone can be charged from a car cigarette lighter, and food can be stored outside (blackouts occur mainly in winter), or you can purchase a cheap inverter option.
