It is a 5-stroke engine which performs a two-stroke work cycle. When the crankshaft of a two-stroke engine rotates once, the engine is doing external work. The first stroke: the piston performs two actions from top dead center to bottom dead center. 1. The spark plug lights up and works - exhaust 2. Close the air inlet, push the mixture from the lower part of the piston into the crankcase, then enter the cylinder through the upper part of the piston. The second blow: the piston. goes from bottom dead center to top dead center. Take two actions: 1. Close all intakes and exhausts and compress the mixture. 2. It takes two piston strokes to complete a power cycle, this is called a two-stroke.
The diesel generator industry is very chaotic, from domestic small workshops to large factories, and from domestic large factories to large joint venture factories. Of course, there are no pure imports, and noDon't believe it. There is! The price difference is very big. It is no exaggeration to say that one machine of a common brand can buy several small workshop machines. It is no exaggeration to say that a machine from the same good brand will last longer than the whole thing. the time of several small workshop machines! For example, the German joint venture brand Saden costs around $3,500, which is good for three years. For example, a small workshop sells for around $1,000 for six months! That's it! If you want to buy something good, look for a big brand, and if you want to buy something that will only be used once, buy something from a small workshop!
