Abstract
An automobile power system in a vehicle may include an intake pipe supplying external air to an engine supplying power to driving wheels, a canister connected with a fuel tank to absorb evaporation gas produced in the fuel tank, an active purging system compressing and supplying the evaporation gas absorbed in the canister to the intake pipe, a diverging line extending from the active purging system to the engine, a diverging valve mounted on the diverging line, and a starting motor rotating a crankshaft when the engine is started. In addition, the evaporation gas absorbed in the canister is supplied to the engine through the diverging line before the engine is restarted, and then the starting motor is operated.
Claims17
An automobile power system comprising:
- an intake pipe supplying external air to an engine supplying power to driving wheels;
- a canister connected with a fuel tank to absorb evaporation gas produced in the fuel tank;
- an active purging system compressing and supplying the evaporation gas absorbed in the canister to the intake pipe;
- a diverging line extending from the active purging system to the engine;
- a diverging valve mounted on the diverging line;
- and
- a starting motor rotating a crankshaft when the engine is started,
- wherein the evaporation gas absorbed in the canister is supplied to the engine through the diverging line before the engine is restarted, and then the starting motor is operated.
A method of restarting an engine in an automobile power system for a vehicle, the method comprising steps of:
- driving the vehicle with the engine stopped;
- determining whether temperature of a catalyst mounted on an exhaust pipe is a catalyst activation temperature or more;
- supplying evaporation gas to the engine by operating a purge pump of an active purging system;
- determining whether a starting motor is operated;
- and
- closing a diverging valve mounted on a diverging line connecting the active purging system and the engine, and stopping operation of the purge pump.
