Problems solved by technology

However, when the gas vehicle engine backfires in this connection sleeve, the huge high-pressure combustion gas produced by the engine combustion chamber will burst out in the direction of the intake manifold, which will cause the problem that the side joint sleeve will fall off.
The general connecting sleeve only plays the role of connecting the engine and the intake manifold. When the engine backfires, there is no pressure relief protection function, and the normal operation of the gas vehicle cannot be guaranteed.

Embodiment Construction

[0010] In Fig. 1 and Fig. 2, a pressure relief hole 2 is provided on the ring wall of the pipe joint 1, and the inner side of the pipe joint 1 is an air intake passage 3, and the inner side of the pressure relief hole 2 communicates with the air intake passage 3, and the pressure relief hole A pressure relief collar 4 is arranged on the outside of the pressure relief hole 2, and the pressure relief collar 4 seals the outside of the pressure relief hole 2.

[0011] The port A of the pipe joint 1 is connected with the end of the intake manifold J and fixed with a fastener, and the other port B of the pipe joint 1 is connected with the intake port of the engine F and fixed with a fastener.

[0012] When the car is running normally, the mixed gas enters the engine F from the A end of the pipe joint 1 to the B end through the intake passage 3 inside the pipe joint 1, and the pressure relief collar 4 seals the pressure relief hole 2.

[0013] When the engine flashes back, the high-p...

Abstract

The adapter sleeve of the engine and the intake manifold of a car powered by gasoline and liquidized oil gas or gasoline and natural gas, comprises pipe fittings, decompression hole, inlet duct and decompression gasket. Inside the pipe fittings sets an inlet duct, decompression holes at the surrounding walls of the pipe fittings. Outside the decompression hole, there is a decompression gasket and the inside of the decompression hole connects with the inlet duct. Port A of the pipe fittings fastens with the end of the intake manifold, and port B of the pipe fittings fastens with the inlet of the engine. It ensures normal running of gas-fueled cars, avoids dropping out of the adapter sleeve when the flashback of the engine occurs with simple in structure.

Description

Technical field [0001] The invention relates to a connecting sleeve between engine intake manifolds used in gasoline / liquefied petroleum gas or gasoline / natural gas dual-purpose fuel vehicles. Background technique [0002] At present, the connection sleeve of the known gas vehicle engine and the intake manifold is a common sleeve made of elastic material, one end of which is connected with the intake port of the engine, and the other end is connected with the end of the intake manifold, and is connected with a tight Firmware fixed. However, when the gas vehicle engine backfires in this connection sleeve, the huge high-pressure combustion gas produced by the combustion chamber of the engine will burst out in the direction of the intake manifold, which will cause the problem that the edge joint sleeve will fall off. The general connecting sleeve only plays the role of connecting the engine and the intake manifold. When the engine backfires, it has no pressure relief protectio...
