spark ignition

基本解释

Two methods for igniting fuel are used, spark ignition and compression ignition.
按点火方式可分为两种：火花点火和压缩点火。
The two major engine types in use are spark ignition (gasoline engine) and compression ignition (diesel engine) which use different types of fuel.
常用的两大类内燃机是火花点火式（汽油机）和压缩点火式（柴油机）内燃机，他们使用不同种类的燃料。
In the near future, spark ignition engines have rapid progress depending on their high efficiency and low pollution for the requirement of energy source and environmentalism.
近年来，由于能源和环保的要求，火花点火天然气发动机以高效、低污染燃烧的优点正在迅速发展。

In most spark ignition engines, a thermodynamic cycle occurs when the piston completes four strokes within the cylinder, and the crankshaft completes two revolutions.
FORBES: How To Get 50 MPG Out Of Your Gasoline Engine
Both Otto cycle(spark ignition) and Diesel cycle engines(compression ignition) engines can be made to run on multiple fuels(petroleum, ethanol, natural gas) The cost is only nominally more than single fuel engines.
FORBES: The U.S. Federal Deficit Reaches A Tipping Point
Instead of sparking the ignition when the piston is close to top dead center (when the air is compressed), that spark occurs as the piston is pulling away, when the air pressure is at its most turbulent, creating much faster ignition and more power.

火花点火
The data structure of visualization model is given and a temperature-color mapping table is created. By using the combustion visualization model, the 3D dynamic visualization for both spark ignition engine and compression ignition dual fuel engine are realized.
文中介绍了模型实现的数据结构，建立了温度—颜色映射表，构造了可视化系统，实现了火花点火内燃机与双燃料压燃式内燃机燃烧过程的三维动态可视化，并给出了效果图片。
