As China's demand for commodity fuels continues to increase, and the degree of foreign dependence on oil imports has increased year by year, research and development of petroleum alternative fuels will have important strategic significance for improving China's energy security. Yao Chunde, a professor at Tianjin University’s School of Mechanical Engineering, led the research team to develop a diesel-methanol combustor technology that breaks through the barriers to the application of methanol, and replaces diesel with methanol, which is rich in raw materials. The replacement rate is over 45%. The technology has won the first prize of the 2016 China Machinery Industry Science and Technology Award at the Machinery Industry Science and Technology Conference recently.
Yao Chunde team developed the key components of the entire methanol injection system and established a complete autonomous development system. Its research and development technology through its own developed electronic control system, after the engine reaches a certain temperature, through the methanol nozzle installed in the intake manifold to inject methanol into the inlet, so that methanol and air to form a homogeneous mixture in the cylinder and diesel Co-firing. The technology also reduces the emissions of nitrogen oxides and soot particulate matter. It does not require urea assistance to meet the National IV and National V emission requirements.
Yao Chunde introduced that the technology is compatible with the existing engine production system of the diesel engine. The installation is simple and the reliability is high. It is only necessary to install the methanol nozzle in the intake manifold, install the methanol fuel tank on the chassis, and the electronic control system can complete the modification. The cost of refitting a car is about twenty thousand yuan. According to the current statistics of the operation of more than 100 heavy-duty vehicles in 12 provinces and cities, according to the current price of diesel and methanol, heavy-duty vehicles using diesel-methanol combustible technology can save fuel costs by 20% to 25%.
