The light vertical shaft series diesel engine and its oil-electric storage mixed energy station (range extender) developed by our company are in the leading domestic position and the international advanced position.
The output shaft of the vertical shaft engine is vertical downward (different from the ordinary engine output shaft is horizontal), directly connected to the drive wheel, saving the heavy and high cost transmission gear box, applied in small machinery and light machinery can significantly reduce weight, save energy, reduce cost, but also can simplify the operation. Diesel energy density is high, good safety, diesel vertical shaft engine than gasoline standing shaft engine torque, life can increase nearly doubled, energy consumption fell nearly half, no gasoline shortcomings such as flammable explosive, high safety, so with diesel vertical shaft engine instead of gasoline standing shaft engine is the inevitable trend of the engine industry in the future.
There is a big technical threshold to replace the gasoline engine with the diesel engine. The diesel engine has high compression ratio and high burst pressure, much greater than the gasoline engine; the high strength of the parts and the control of vibration, so the volume and weight of the diesel engine are larger than that of the gasoline engine; in addition, the horizontal movement of the vertical shaft diesel piston weight; these are the reasons why the diesel engine is not selected in light and small machinery. The light diesel engine of our company adopts new materials, new processes and finite element design, which solves the lightweight problem of small diesel engine, and controls the weight and volume of the diesel engine close to the gasoline engine, which is a revolutionary progress of diesel engine technology. On the basis of lightweight, the lubrication system is further designed and optimized to achieve the ideal oil thermal load control; the excessive vibration of diesel engine and the short fault-free running time are solved, thus overcoming the final barrier of diesel engine to replace the gasoline engine.
In order to meet the arrival of the era of artificial intelligence, the company will also in small vertical shaft diesel digital and intelligent continue to research, development of digital vertical shaft diesel will store in hybrid energy station and range extender large-scale application scenarios for energy saving, consumption reduction, mute and equipment long life, nearly zero emissions requirements, such as in the process of national technology innovation to make great contributions.
Vertical shaft diesel engine is mainly used in courtyard mower, mount type mower, rotary tiller, outboard machine, floor machine, unmanned garden machinery, unmanned plant protection machinery, small generator, small construction machinery, light field drilling rig, energy storage range extender machinery, replace single double cylinder air cooled vertical shaft gasoline machine, huge demand. At present, the main manufacturers of gasoline vertical shaft are: the United States, Kohler, Japan Honda, Kawasaki, China Zongshen, Lifan, Longxin, Shen, and nearly 100 Sichuan, Zhejiang, Jiangsu, Guangdong and other places of gasoline engine enterprises, and the domestic almost see mature and reliable vertical shaft diesel engine.
To sum up, light vertical shaft diesel engine is difficult to design, with high technical content, good product quality and wide application range. It is a high-tech high-end manufacturing product with high added value, with huge market and strong vitality.
