In view of this, the utility model aims to provide a kind of motor exhaust that utilizes as the LNG vapour device of auxiliary thermal source, utilize motor exhaust for auxiliary thermal source, LNG is for motor in vaporization, promote vaporizer air demand, reduce the heat of motor exhaust to the damage of braking, turn to pipeline to cause, improve vehicle security.

For achieving the above object, the utility model provides a kind of motor exhaust that utilizes as the LNG vaporizer of auxiliary thermal source, and comprising: water jacket, coil pipe, water jacket has water intake, water outlet, water intake exports with engine coolant and is connected, and water outlet is answered back with engine coolant and is connected; Coil pipe has liquid entering hole, air outlet, and liquid entering hole is connected with LNG gas cylinder supplier, and air outlet is connected with knock out drum; Coil pipe is fixedly installed in water jacket inside.

This vaporizer also comprises: outlet pipe, and outlet pipe penetrates from water jacket side, passes from water jacket opposite side; Coil pipe is inner around outlet pipe layout at water jacket, and outlet pipe is fixedly connected with water jacket.

The two ends of outlet pipe are connected with engine exhaust emission device respectively.

Adopt the LNG vaporizer of said structure, the heat utilizing motor to produce is as automobile-used LNG vaporizer auxiliary thermal source, both can solve because engine coolant provides that the limited LNG evaporating capacity that causes of thermal source is not enough, engine power performance declines or problem of stopping working, also can slow down motor exhaust thermal radiation to aging, the rate of decay of braking, turn to pipeline to cause, improve vehicle security.

In an embodiment, the two ends of outlet pipe are respectively equipped with flange, and flange has bolt hole, and outlet pipe, by flange and motor tapping equipment bolt, makes outlet pipe and the easy access simultaneously of engine exhaust emission device compact siro spinning technology.

In an embodiment, bottom water jacket, be also provided with sewage draining exit, easy access or discharge engine coolant.

The motor exhaust that utilizes of the present invention is as the LNG vaporizer of auxiliary thermal source, and can take engine coolant as main heat source, motor exhaust be auxiliary thermal source, and LNG is for motor in vaporization.Solve because engine coolant provides that the limited LNG evaporating capacity that causes of thermal source is not enough, engine power performance declines or problem of stopping working, also can slow down motor exhaust thermal radiation to braking, aging, the rate of decay that turn to pipeline to cause, improve vehicle security.
