    • An LPG fuel injection system is provided to improve precision of vehicle control and reduce back fire by preventing fuel leakage to an intake manifold. An LPG fuel injection system includes an engine(10), an intake valve(20), an LPG injector(30), an intake manifold(40), a shut valve(50), an air filter(60), and a throttle body(70). The intake valve is disposed at one side of the engine. The LPG injector is arranged to inject LPG fuel to the path connected to the intake valve. The intake manifold serves as a path for supplying air to the intake valve. The shut valve is arranged at one end of the intake manifold, and operates in interlock with a cam shaft of the engine. The air filter controls air supplied to the intake valve. The throttle body connects the air filter and the intake manifold.
    • 提供液化石油气燃料喷射系统,以提高车辆控制的精度,并通过防止燃油泄漏到进气歧管来减少反火。 液化石油气燃料喷射系统包括发动机(10),进气门(20),液化石油气注入器(30),进气歧管(40),关闭阀(50),空气过滤器(60) 体(70)。 进气门设置在发动机的一侧。 LPG喷射器被布置成将LPG燃料喷射到连接到进气阀的路径上。 进气歧管用作向进气阀供应空气的路径。 关闭阀布置在进气歧管的一端,并与发动机的凸轮轴联动操作。 空气过滤器控制供给进气阀的空气。 节气门体连接空气过滤器和进气歧管。

    • An engine intake device is provided to prevent backfire caused due to valve overlap and pulse wave and reduce intake pressure and intake noise by returning backflow air to a cylinder in proportion to the air intake force. An engine intake device(1) includes a first pipe(10) and a second pipe(20). The first pipe has two to three venturi pipes(12) arranged at an outdoor air inlet side of an intake path for sucking outdoor air into an engine combustion chamber so as to increase air flow rate. The second pipe is arranged to cover an outer surface of the first pipe, and extended further than one end of the first pipe at an outdoor air outlet side such that a chamber(22) serving as a space for containing air flowing backwardly to the combustion chamber is formed. The first pipe and the second pipe are overlapped and welded with each other on the central axial line of the second pipe.
    • 提供一种发动机进气装置,以防止由于气门重叠和脉搏波而引起的回火,并且通过与进气力成比例地将回流空气返回到气缸而减小进气压力和进气噪声。 发动机进气装置(1)包括第一管(10)和第二管(20)。 第一管道具有布置在进气路径的室外空气入口侧的两个至三个文丘里管(12),用于将室外空气吸入发动机燃烧室,以增加空气流量。 第二管被布置成覆盖第一管的外表面,并且在室外空气出口侧比第一管的一端延伸,使得用作容纳空气的室(22)向后流动到燃烧 室形成。 第一管和第二管在第二管的中心轴线上彼此重叠并焊接。
