Diesel is used to commemorate the inventor of the high speed new stationary diesel engine-Rudolf Diesel. Diesel was born in 1858, German, and graduated from the Technical University of Munich. In 1879, he graduated from Diesel University and became a refrigeration engineer. In his work, Diesel deeply felt that the efficiency of the steam engine was extremely low at that time, and the idea of designing a new engine had sprouted. After saving some money, Diesel resigned as a refrigeration engineer and opened an engine laboratory.
In response to the weakness of the steam engine's low efficiency, Diesel focused on developing high efficient internal combustion engines. At the end of the 19th century, petroleum products were extremely rare in Europe, so Diesel decided to use vegetable oil to solve the fuel problem of the machine (the peanut oil was used for the experiment). Because of the poor ignition performance of vegetable oil, the structure of Otto internal combustion engine cannot be applied. Diesel decided to increase the compression ratio of the internal combustion engine, and used the high-temperature and high-pressure fuel produced by the compression. Later, this compression ignition engine cycle was called the Diesel cycle.
Like all great inventors, Diesel had many difficulties on the way. Experiments have proved that vegetable oil combustion is unstable and the cost is too high. Fortunately, at that time, petroleum products were gradually popularized in Europe. Diesel chose the diesel as the fuel for the machine. The structural strength of compression ignition high quality electric starting diesel engine is always a problem. In one experiment, the parts on the cylinder were scattered like shell fragments, almost causing casualties. The experiment was not smooth, and Diesel's funds were gradually exhausted. He had to return to the refrigerator factory to make a living. But Diesel did not succumb to the difficulties. He used his spare time to continue experimenting and perfected his machine step by step.
In 1892, Diesel finally developed a practical diesel-powered compression ignition powerful water cooled diesel engine. This kind of engine has high torque, low fuel consumption, and can use inferior fuel, showing brilliant development prospects. Diesel immediately invested in the commercial adventure of diesel engine production. Unfortunately, as a good engineer, Diesel lacks business acumen. He was gradually in trouble economically. In 1913, Diesel was on the verge of bankruptcy. But the diesel engine invented by Diesel has been more and more widely developed in the fields of automobiles, ships and the entire industry.
In 1976, the German Volkswagen first adopted a diesel engine in the golf car.
In 1989, the German Volkswagen Golf Diesel was awarded the title of "Low Emission Vehicle". In the same year, Volkswagen obtained part of the technology from Fiat’s R&D organization and manufactured the first 5-cylinder engine R5 TDI with supercharged and direct injection technology. This engine was put on trial for the Audi 100 model.
In 1990, German Volkswagen officially launched the supercharged and direct injection series diesel engine TDI. Since then, German Volkswagen has been at the forefront of the world in the development and application of diesel power technology.
In 1993, developed a 4-cylinder new motor turbocharge diesel engine (TDI).
In 1995, developed a naturally aspirated direct injection (SDI) diesel engine.
In 1995, developed the variable cross-section turbocharger VGT.
In 1998, developed pump nozzle (Pumpe Düse) technology.
In 1999, the Lubo sedan diesel engine with a fuel consumption of 3 liters per 100 kilometers was developed. The birth of an upgraded diesel-powered car created a record of 0.99 liters of fuel consumption per 100 kilometers, making it the most fuel-efficient car in the world. The new stationary good condition diesel engine adopts aluminum naturally aspirated single-cylinder diesel engine, adopts advanced high-pressure direct injection technology, and the displacement is 0.3 liters.
In 2002, FAW-Volkswagen took the lead in placing the Jetta SDI sedan in the Chinese market.
In 2004, FAW-Volkswagen introduced TDI technology.
