In Lanchester's design, two balance shafts rotated in opposite directions at twice the crankshaftspeed to cancel out the niggling secondary vibrations.
Lanchester的设计中，两个平衡轴以两倍于机轴转速，反向地转动，抵消了无用的次生振动。

This paper presents a nonlinear autoregressive exogenous (NARX) model to approximate dynamics of crankshaftspeed with the mass of the idle feeding fuel and the spark advance.
