Abstract: PURPOSE: An eliminating method of sediments from an LPG(Liquefied Petroleum Gas) vehicle is provided to optimize engine torque all the time by automatically eliminating sediment on a bypass pipe for idle control in an LPG vehicle. CONSTITUTION: An ECU(Engine Control Unit,20) performs a dieseling mode of keeping rotation by self-ignition through overheating in an engine even though a start switch(SW1) is turned off. During the dieseling mode, the power of a battery(10) is supplied to each unit during first set time by a power latch mode. The ECU closes a bypass pipe through an idle speed control unit(30). Then the ECU eliminates first sediments by a sediment eliminator(40). Driving the sediment eliminator at a duty ratio of 25% is repeated during the first set time. A drive unit(41) slides an eliminating plate(43) vertically for 25% to eliminate sediments including carbon on the bypass pipe. The ECU turns off and on the power latch mode and eliminates second sediments. The sediment eliminator is driven at a duty ratio of 75% for second set time. The eliminating plate slides up and down for 75% to eliminate sediments. Thereby, all of the sediments are eliminated from the bypass pipe. Eliminating sediments is finished when the start switch is turned on and the engine is started.
