Ethanol engine system
First Claim
1. An ethanol engine system comprising:
- a reservoir tank of an aqueous ethanol solution;
a first supply device, including at least a first injector and a first pump, which supplies the aqueous ethanol solution in the reservoir tank to a reformer;
a separator which separates a mixed gas into gas and liquid by cooling the mixed gas including a reformed gas fed from the reformer and condensing a water vapor included in the mixed gas;
a reformed gas supply device, including at least a second injector and a second pump, which supplies the reformed gas separated by the separator to an engine;
a recovery tank which collects a recovery solution separated in the separator; and
a first recovery solution supply device, including at least a third injector and a third pump, which supplies the recovery solution in the recovery tank to the reformer and a second recovery solution supply device, including at least a fourth injector and a fourth pump, which supplies the recovery solution in the recovery tank directly to a combustion chamber of the engine.

Abstract
An ethanol engine system stabilizes components of reformed gas generated by a reformer and a calorific value of fuel supplied to an engine. The ethanol engine system includes a reservoir tank for an aqueous ethanol solution, a first supply device that supplies the aqueous ethanol solution to the reformer, a separator that cools mixed gas fed from the reformer, including the reformed gas, condenses water vapor included in the mixed gas and separates into gas and liquid, a reformed gas supply device that supplies the reformed gas separated by the separator to the engine, a recovery tank that collects a recovery solution separated by the separator, and a first recovery solution supply device that supplies the recovery solution in the recovery tank to the reformer or a second recovery solution supply device that supplies the recovery solution in the recovery tank to a combustion chamber of the engine.
