Fig.4

Installation of inlet and outlet pipes

The combustion air must be inhaled from the fresh air outside the vehicle; The exhaust gas from combustion must be discharged into the atmosphere through the exhaust pipe, and must not enter the car. Prevent the exhaust gas from burning to cause the danger of poisoning.

Pipe line through the vehicle's outer wall or bottom through hole, must be able to seal to prevent exhaust entry.

Inlet pipe and exhaust pipe must be equipped with accessories of this machine.

The connection between the intake pipe and exhaust pipe and the main engine shall be fastened on the combustion inlet and exhaust pipe with matching clips. The outlet of the exhaust pipe should be positioned so that the discharged gas is not taken in by the intake pipe or the car heating fan (i.e. away from the intake pipe and car heating fan).

Inlet pipe and exhaust pipe, from the fuel stove to the car, should use downward direction (Figure 5), otherwise, in the lowest point of the pipeline should open a 4mm condensation water discharge hole. If bending is required, the bending radius of the pipe shall not be less than 50mm.Moreover, the sum of all bending angles of each tube must not exceed 270°.

 

 

When the fuel stove is working, the temperature of exhaust pipe is very high. When installing, it must be kept away from hot objects such as plastic parts of the car body and properly fixed.

 

Intake and exhaust pipes are easy to freeze in winter and should be checked frequently for patency.

Inlet pipe and exhaust pipe are stainless steel bellows. The connection between the engine and the combustion engine shall be fastened on the inlet and outlet of the exhaust pipe respectively with corresponding supporting clips.

No coating should be added to the surface of the fuel stove.

Warning: Failure to comply with the above requirements may result in fire.

 

Fuel system connection

 

The fuel is extracted from the vehicle fuel tank, and the fuel is transported and adjusted through a special fuel pump (provided by the manufacturer). Fuel is not allowed to be extracted from the vehicle engine's return system or downstream of the vehicle's internal delivery pump. Please install using fuel hoses and piping within the delivery range.

Fuel shall conform to national standards Gb19147-2013 for vehicle diesel standard.

In winter, the fuel should meet the requirements of low temperature, and no biofuel should be used.

Fuel line system

 

 

Fig.6

Installation of fuel line

The pipeline must be supplied with this machine fitting, namely nylon fuel pipe with good light resistance and thermal stability. Permissible length of fuel line: the maximum length of fuel line on the inlet side is 2m, and the maximum length of the pressure side is 6m.As shown in figure 6.

 

Safety code for fuel lines

Be sure to use a hose cutter or a sharp tool to cut the fuel hose and piping to a certain length. The cut area cannot be compressed and must be free of burrs. Fuel lines must be firmly connected to prevent damage and/or noise due to vibration (approximately 50 cm is recommended between connection points). Fuel lines must be protected against mechanical damage. The laying of fuel pipeline will not adversely affect the stability of vehicle rotation and engine operation. Protect fuel carrying parts from high temperatures that may affect operation (use suitable fiberglass lined aluminum thermal protective hoses). Do not install or fix fuel line near heater or exhaust line of vehicle engine. If the lines are crossed, keep sufficient distance from the hot parts -- if necessary, provide a thermal radiation shield. The tubing should be installed in a way that prevents flying stones from hitting, away from hot parts of the vehicle, and protective devices should be installed if necessary.

 

Installation of fuel pump

The fuel pump shall be fixed with the fuel pump fixed jacket (rubber). The fuel outlet of the fuel pump should tilt upward, and its installation Angle should be selected within the range of 15° ~ 35° (As shown in Fig.7).When conditions permit, the tubing between the fuel pump and the heater should rise gradually. To prevent the fuel pump from heating (maximum operating temperature 40℃), do not install near the exhaust pipe.

①Allowable installation angle

②Optimum installation angle

 

The height difference between the fuel level and the pump, and the height difference between the pump and the main engine inlet, will generate pressure (or suction) in the fuel path, so these dimensions should be in accordance with the requirements in Figure 7 (in a closed tank, negative pressure will be generated, in which case, the minimum fluid level maximum diagram of the tank should not exceed 0.4m).

 

Connection between heater and fuel pump The tubing direction from the fuel pump to the main engine should be as upward as possible. Mark a suitable place on the floor of the vehicle for crossing

The hole where the fuel line and fuel pump are connected to the cable. Before drilling, be sure to check for hidden cables, fuel lines, frame sections, etc. Then seal with underbody protection

The edge of an opening in the floor of a vehicle. In order to prevent the cable between fuel pipe and fuel pump being cut, please add the inlet bushing or the section edge protection material.

Tubing should be tied in an appropriate place for fixation, and the binding spacing should not be greater than 50cm.

The connection between fuel pipe and fuel pump, main engine and fuel tank (fuel extractor) should use the fuel pipe joint provided by this machine and tighten with the fuel pipe clip. Prevent bubbles from forming at the junction (Figure 8).

Used when drawing fuel from the vehicle's own tank. During installation, the 25±0.2 hole size of the installation hole on the fuel tank (or fuel tank cover) shall be noted, with neat edges and smooth surroundings to ensure a good seal between the fuel suction tubing seat. The distance between the lower mouth of the suction pipe and the bottom of the fuel tank should be 30-40mm, which can not only ensure the full absorption of fuel, but also prevent the impurities deposited at the bottom of the fuel tank from being inhaled.

 

Mounting control switch

The fuel stoves must be operated by special rotary switches. See related instructions for details.

 

Wiring diagram
