| 摘要 |
A supercharged internal combustion engine system wherein during periods of high power demand the weight of combustion chamber charge is increased by cooling a portion of intake air in a turboexpander using high-pressure air from a storage tank. In addition to increasing engine output power, cold air intake also reduces engine pre-ignition (knocking) thereby reducing emissions. Mechanical energy produced during expansion of high-pressure air may be used to operate a turbocompressor, which compresses intake air and further increases charge weight. Effective supercharging is achieved even at low engine speeds. One of the objects of the invention is to obtain more power from small displacement ICE and thus providing automotive vehicles with sufficient acceleration in addition to good fuel economy. Another object of the invention is to enhance turbocharged engines and reduce their response lag. Air storage tank may be recharged using energy recovered during vehicle deceleration. |
