To improve the synthesis or completion of 3D environments, the disclosed techniques train and execute a machine learning model to iteratively convert an incomplete representation of a 3D scene into a more complete representation of the same 3D scene. For example, the machine learning model may incre...
the serrated structure on the surface of the piston ring helps to scrape off excess lubricating oil from the cylinder wall and bring it into the crankcase, avoiding waste caused by excessive lubricating oil entering the combustion chamber. At the same time, it scrapes off carbon slag and other ...
1968 – 1973: Over the following 50 years or more, cheap, abundant gasoline and ongoing advancements in the internal combustion engine reduced the necessity for alternative fuel vehicles. However, throughout the 1960s and 1970s, petrol costs climbed, boosting interest in electric cars. 1973: Many...
Lean-burn natural gas vehicles are a promising mid-term alternative to gasoline and diesel vehicles due to the higher mass energy density of methane and lower carbon dioxide and NOx emissions1,2,3,4,5. However, lean-burn operation of a natural gas engine results in incomplete combustion of ...
