Diesel generators have been used in many applications for a long time, including power generation in the oil and gas. Compared with petrol, natural gas, and biogas, diesel generators have become the mainstream, mainly due to the efficient and reliable continuous power supply from the internal combustion method.
The most import advantage of diesel engines is that they have no sparks, and its efficiency comes from compressed air.
Diesel engines pressure-burn the atomizing fuel by injecting diesel fuel into the combustion chamber.The temperature of the compressed air in the cylinder rises, so it can be burn instantly without ignition by a spark plug.
The diesel engine has the highest thermal efficiency compared to other internal combustion engines. And precisely because of its high energy density, burning diesel fuel provides more power than gasoline of the same volume. The high compression ratio of diesel allows the engine to extract more power from the fuel during hot exhaust gas expansion. This larger expansion or compression ratio increases engine performance and improves efficiency.The higher efficiency of diesel engines, the higher economic benefits. The fuel cost per kilowatt produced by diesel engines is much lower than other engine fuel types such as natural gas and gasoline. According to relevant results, the fuel efficiency of diesel engines is generally 30% to 50% lower than gas engines.
The maintenance costs of diesel engines is lower. They are easier to maintain due to their lower operating temperature and non-spark ignition system. The high compression ratios and high torques of the diesel engine make their components higher strength. Diesel oil is light oil, it can provide higher lubricity for cylinders and unit injectors and extend their service life. Moreover, the diesel engine can run reliably for a long time. For example, a water-cooled diesel generator set at 1800 rpm can run for 12,000 to 30,000 hours before a general maintenance. Natural gas engine typically runs for only 6000-10,000 hours and requires major maintenance.
Now, the design and operating characteristics of diesel engines have also been improved significantly, which can be used in harsh environments and provide remote services. Moreover, diesel generators already have a silent function, for example a silent diesel generator, which adopts an overall fully enclosed structure with strong sealing to ensure sufficient strength. It can be divided into three parts: the main body, the air inlet chamber, and the exhaust chamber.The door of the box body is designed with double-layer soundproof , and the inside of the body is treated with noise reduction. The materials of noise reduction are eco-friendly and flame-retardant materials are harmless to the human body. When the unit is in normal operation, the noise at 1m from the cabinet is 75dB. It can be fully applied to include hospitals, libraries, firefighting, enterprises and institutions, and densely populated areas.
At the same time, diesel generators have more convenient and convenient mobility. The series of mobile trailer generator sets use a leaf spring suspension structure, equipped with a mechanical parking brake and an air brake connected to the tractor, and have a reliable air brake. Interface and hand brake system to ensure safety during driving. The trailer adopts a height-adjustable bolt-type tractor, movable hook, 360 degree turntable, and flexible steering. It is suitable for tractors of various heights. It has large turning angles and high maneuverability. It has become the most suitable power generation equipment for mobile power supply.
