C1-C3短化学动力学机理（圣地亚哥机制）涉及40种此类物质中的235个基元反应，通过在7种额外物质中添加22个化学动力学步骤及其相关的反应速率参数，将其扩展到C4，以包括正丁烷的点燃和燃烧在一系列条件下，包括低温和高温化学，以及高压和低压。测试的预测对测得的点火延迟和层流燃烧速度的报告，作为比较与最近的测量在射流搅拌反应器，支持的预测机制，这可能是有用的燃烧计算，特别是当较大的机制将是太耗时，以适应。
A C1–C3short chemical-kinetic mechanism (the San Diego mechanism), which involves 235 elementary reactions among 40 such species, is extended to C4by adding 22 chemical-kinetic steps, among 7 additional species, with their associated reaction-rate parameters, to include the ignition and combustion of n-butane over a range of conditions that encompasses both low-temperature and high-temperature chemistry, as well as both high and low pressures. Tests of predictions against measured ignition delays and laminar burning velocities are reported, as are comparisons with recent measurements in jet-stirred reactors, supporting the predictions of the mechanism, which may be useful in combustion computations, especially when larger mechanisms would be too time-consuming to be accommodated.
