When there is a blackout of a personal plot, apartment, store or production workshop, then this problem can be solved if you buy a gasoline electric generator in a timely manner, which is encountered with a two-stroke or four-stroke. Looking ahead, let's say that the most popular solution for home is 5 kW generator .
Two-stroke gasoline generators benefit from lightness, reliability and low cost. In their design, they do not have valves (for this, inlet ports for the fuel mixture and outlet ports for exhaust gases are used), a complex timing system and massive (heavy) lubrication and cooling systems. All this allows you to get the most powerful two-stroke generator of such a low weight that only two adults can lift it.
The fuel consumption of these versions is economical. Medium (up to 2 kW) power versions consume 0.5 liters of fuel for one hour. This is quite economical, and the fuel is a mixture of gasoline and synthetic (you can also use mineral) oil in a ratio of 30: 1. Adding oil to the fuel dramatically solves the problem with starting the engine in extremely low cold weather, then four-stroke versions, due to thickening of the oil, start with difficulty.
Two-stroke gasoline generators of the budget line are most often started with the help of magneto - just pull the rope, as the engine, provided that fuel is supplied to the carburetor, will immediately start. More expensive versions are equipped with electric starters. But in any case, they are installed on a tubular steel chassis, which is excellent not only for low weight, but also for the ability to absorb engine vibration during operation.
Four-stroke gasoline generators are valuable in terms of increased reliability as the internals of the piston group receive better lubrication. And they are additionally cooled by the addition of a liquid cooling system - a generator operating at increased power in the summer will never overheat and fail prematurely. Due to better ventilation of the combustion chamber, they have an increased level of efficiency (not less than 10 percent), which has a positive effect on fuel consumption. If you need to power your house or machine with cheaper electricity, it is recommended to choose a gasoline four-stroke generator that can be easily started with the help of an additional starter and battery. The only drawback of these versions is the increased weight. But if we consider that they are installed on wheeled chassis, convenient in terms of transportation to the destination, then this drawback will not be considered critical.
