摘要： The present invention provides a process for reducing abnormal combustion within a combustion chamber of the engine. The process can include simulation of the piston-driven internal combustion engine with oil droplets from the crankcase entering into the combustion chamber. In addition, the oil drops entering into the combustion chamber can be simulated as hot spots, as can simulation of fuel combustion within the combustion chamber. A probability of pre-ignition for at least a portion of the simulated hot spots as a function of the simulated fuel combustion and the simulated hot spots within the combustion chamber can be calculated and based on the calculation a combustion chamber parameter can be altered such that pre-ignition within the combustion chamber is reduced.

摘要： The present invention provides a process for designing and manufacturing an ignition system for an internal combustion engine. The process can include performing a plurality of simulations that include simulating an electrical circuit with a spark initiating device for igniting the fuel mixture within an internal combustion chamber, an electrical breakdown proximate to the spark initiating device, a plasma arc and an afterglow regime.

摘要： The present invention provides a process for designing and producing a cooling fluid for use in a cooling system. The process uses molecular dynamics to calculate the thermal properties of one or more fluid-nanoparticle solutions, and thereby aids in the study, selection and/or production of desired cooling fluids based on first principle simulations.
