    摘要： An engine exhaust gas purifier includes: an injection controller allowing a fuel injection valve to inject fuel near the top dead center on each compression stroke; an EGR amount controller for controlling the amount of exhaust gas recirculated into a combustion chamber; an excess air ratio controller for controlling the excess air ratio so that the local equivalence ratio in a late combustion stage is lower than the equivalence ratio at which soot is produced; and an intake air temperature controller for controlling the temperature of intake air after being mixed with exhaust gas. The intake air temperature controller controls the temperature of intake air within a temperature range lower than an upper temperature limit below which a predetermined ignition delay time can be secured and higher than a lower temperature limit above which the production of HC and CO can be avoided.

    摘要： There is provided a method of starting a spark ignition engine having multiple cylinders. The method comprises supplying air and fuel for restart into a first cylinder before the engine completely stops, and igniting the mixture of the air and the fuel in the first cylinder in response to an engine start request. In accordance with the method, by supplying air and fuel into the first cylinder before the engine completely stops, the mixture of air and fuel in the first cylinder may be homogeneous at the time of the engine start request. Also, there may be less mixture turbulence and combustion may propagate better within the cylinder. These conditions may reduce the rate of combustion in the first cylinder after a start request is initiated. The slower combustion rate may decrease temperature of the combusted gas while the cylinder wall temperature is relatively low because the engine has stopped. As a result, the slower combustion may reduce heat loss in the first cylinder because of the smaller difference between the temperatures of the combusted gas and the cylinder wall. Consequently, more energy may be directed from the first cylinder to the crankshaft, so that the engine restart becomes more reliable.

    摘要翻译： 提供了一种起动具有多个气缸的火花点火发动机的方法。 该方法包括在发动机完全停止之前将空气和燃料重新启动进入第一气缸，并响应于发动机起动请求点燃第一气缸中的空气和燃料的混合物。 根据该方法，通过在发动机完全停止之前将空气和燃料供应到第一气缸中，在发动机起动请求时，第一气缸中的空气和燃料的混合物可以是均匀的。 此外，可能会有较少的混合物紊流，并且燃烧可能在气缸内更好地传播。 这些条件可以在开始启动请求之后降低第一气缸中的燃烧速率。 由于发动机停止，较慢的燃烧速率可能降低燃烧气体的温度，同时气缸壁温度相对较低。 结果，较慢的燃烧可以减少第一气缸中的热损失，因为燃烧气体和气缸壁的温度之间的差别较小。 因此，更多的能量可以从第一气缸引导到曲轴，使得发动机重起变得更可靠。
