Construction Machinery Generator principle alternator by structure, speed restrictions and other conditions of construction machinery engines suppliers, external output current capacity is limited, the output current capability in order to evaluate the external mechanical engineering generator engine manufacturers, the generator 2/3 of the maximum current output of the generator set to the rated current brand of construction machinery engine speed reaches the rated current is set at rated speed. When the generator factory, through testing to determine the rated speed and rated current, and included in the product specification, the generator rated speed and rated current is an important indicator of performance evaluation of the generator. Diesel variety. According to the duty cycle can be divided into four-stroke and two-stroke diesel engines. ② Press cooling can be divided into water-cooled and air-cooled diesel engine. ③ Press intake can be divided into pressurized and non-pressurized (naturally aspirated) diesel engine. ④ can be divided into a high speed by the rotational speed (greater than 1000 rev / min), medium speed (300 to 1000 rev / min) and low speed (less than 300 rev / min) diesel engine. ⑤ Press the combustion chamber can be divided into direct injection, swirl chamber and the pre-combustion chamber diesel engine. ⑥ by gas pressure can be divided into single-acting and double-acting and opposed piston diesel engines.
