Embodiment Construction

[0020] Hereinafter, a system for starting an LPI vehicle engine is described with reference to the accompanying drawings.

[0021] figure 1 is a block diagram of a system for starting an LPI vehicle engine according to an embodiment of the inventive concept. figure 2 and image 3 is a diagram for describing a system for starting an LPI vehicle engine according to an embodiment of the inventive concept.

[0022] Such as figure 1 As shown in , the system for starting an LPI vehicle engine according to an embodiment of the present inventive concept includes a signal transmission unit 100 configured to transmit a door opening signal. The first controller 200 is configured to determine whether an ignition-on state of the LPI engine is required, and to operate the fuel pump 10 when the ignition-on signal is generated. The second controller 300 is electrically connected with the first controller 200 and configured to receive the door opening signal transmitted from the signal tr...

Abstract

a system for starting an LPI vehicle engine includes a signal transmitting unit configured to transmit a door opening signal. A first controller is configured to determine whether an ignition-on state of an engine is required and configured to operate a fuel pump when an ignition-on signal is generated. A second controller is configured to receive the door opening signal transmitted from the signal transmitting unit and configured to operate the fuel pump by transmitting an operation signal corresponding to the ignition-on signal when the door opening signal is input.

Description

technical field [0001] The present disclosure relates to a system for starting an LPI engine capable of reducing the waiting time when starting the LPI engine more quickly. Background technique [0002] Generally, a liquefied petroleum injection (LPI) system enables direct injection of high-pressure liquefied fuel using a brushless DC (BLDC) motor installed in a fuel tank. The LPI system reduces pollutants that cause air pollution and solves operational problems such as engine not starting in cold weather. Since the LPI system can increase the engine output power by about 23% compared with the existing LPG system and is an environment-friendly system, the LPI system has been widely used in recent years. [0003] In order to start a conventional LPI engine, the pressure in the fuel line must be higher than the reference pressure. That is, LPI engine start requires a certain amount of waiting time after the ignition key is turned on until fuel pressure reaches a desired leve...
