Discharge Pipe 90 Degrees for Vialle LPi Injectors - Length 18 mm with 1 Groove - LPG Injector Nozzle for Intake Manifold - Part Number 270146.0
Essential Component for LPi Liquid Injection Systems
This discharge pipe 90 degrees from Vialle is a crucial component for LPi installations where liquid LPG is injected into the engine. The injector nozzle with part number 270146.0 is mounted directly in the intake manifold and ensures optimal distribution of LPG gas to the combustion chamber. With a length of 18 mm and a 90-degree angle, this nozzle fits perfectly in tight engine compartments where straight mounting is not possible. The pipe features 1 groove under the O-rings that guarantees a gas-tight seal and prevents false air from being drawn in during the operation of the LPG injectors.
Technical Specifications and Material
The discharge pipe is manufactured from high-quality brass that resists the aggressive properties of liquid LPG and the high temperatures in the intake port. The 90° bent shape allows the LPG injector to be mounted at an angle, which is essential for vehicles with limited space around the intake manifold. The total length of 18 mm is carefully calculated to achieve optimal gas distribution without the gas arriving too early or too late in the cylinder heads. The groove for O-rings is positioned correctly to create, together with the sealing ring (sold separately, O-ring 3.0 x 1.5 mm), a perfect connection between the discharge pipe and the intake manifold.
Compatibility and Applications
This Vialle LPi discharge pipe is specifically designed for liquid injection systems from Vialle and is compatible with various vehicles equipped with an LPi conversion, including Volvo, Renault, Opel, BMW, and other brands. The discharge pipe is used when LPG injectors are mounted directly on the engine manifold, which is the most common installation method for sequential LPG systems. The component is essential for a reliable LPi installation where liquid LPG under pressure is injected directly into the intake ports, just before the intake valves. This ensures better engine performance and fuel efficiency compared to older vapor systems.
Installation and Maintenance
When installing the discharge pipe 90°, you must first check that the intake manifold is properly cleaned and free from residues. Place the O-ring in the groove of the discharge pipe and optionally apply a thin layer of glycerin or silicone grease for better sealing. Gently push the nozzle into the pre-drilled opening of the intake manifold until it is fully inserted. Then attach the LPG injector to the discharge pipe using the corresponding clamping plate or mounting bracket. Ensure that the connection between the injector and the discharge pipe is properly sealed with the appropriate seals. After installation, check for gas leaks by starting the engine and checking all connections with leak spray or soapy water. In case of wear or damage, the discharge pipe must be replaced to prevent engine problems such as irregular idling, misfiring, or false air intake. Regular inspection during the annual LPG maintenance is recommended.
