| 主权项 | 1. A method for an engine, comprising: during an automatic stop, injecting a water-containing fluid onto a closed intake valve of a cylinder while the engine is at rest, wherein the water-containing fluid is vaporized in response to contacting the closed intake valve; on a subsequent restart, fueling the cylinder after at least one at least partial intake stroke and subsequent exhaust stroke are performed in the cylinder; and passing the vaporized water-containing fluid to the exhaust prior to initiating combustion in the cylinder. | ||
