Working principle of automobile gas heater: the motor drives the fan to rotate at high speed, the vacuum switch detects negative pressure, and the gas circuit solenoid valve opens. The fan sucks in combustion air and gas at the same time, which are fully mixed in the air-fuel mixer and then ejected from the burner. The igniter discharges through the ignition electrode to ignite the gas, which is fully burned in the combustion chamber and then passes through the heat transfer sheet and finally discharged into the atmosphere from the exhaust pipe. The heat transfer sheet absorbs heat to heat the circulating liquid in the heat exchanger, and the liquid is sent out under the action of the circulation pump.

Product Description

Product Application

Overview & Working Principle:

The motor drives the fan to rotate at high speed, the vacuum switch detects negative pressure, and the gas circuit solenoid valve opens. The fan sucks in combustion air and gas at the same time, which are fully mixed in the air-fuel mixer and then ejected from the burner. The igniter discharges through the ignition electrode to ignite the gas, which is fully burned in the combustion chamber and then passes through the heat transfer sheet and finally discharged into the atmosphere from the exhaust pipe. The heat transfer sheet absorbs heat to heat the circulating liquid in the heat exchanger, and the liquid is sent out under the action of the circulation pump.

Main Applications:

It can be widely used to provide heat source for low-temperature engine starting and cabin heating of natural gas buses, passenger cars and trucks.

Features:

EU E-MARK certificate compliant, meeting European 15-year scrap standards.
YJT series uses natural gas (CNG or LNG) with fully automatic program control.
Safe and reliable operation with exhaust emissions close to zero pollution.
Negative pressure gas supply system through the gas reducer for enhanced safety.
Fast ignition and high combustion efficiency.
Fault shutdown alarm function with indicator light flash codes for convenient maintenance.

Installation Guidelines

Fix the heater horizontally. Leave >170mm space at the air inlet and >150mm at the top for maintenance.
Install an exhaust elbow to prevent gas from entering the cabin.
If installed in a cabin, ensure an air inlet area of at least 400cm² with a filter. Keep away from flammable objects.
Ensure a rear vent of at least 150cm² for airflow.
Gas inlet pipe diameter should be ≥Φ15 and length <1 meter to ensure supply.
Follow the circuit diagram; use the engine housing as the negative pole and 15A insurance.
The water circuit must include an expansion tank at the highest point; the heater should be at the lowest point.
Install a gas leak alarm in the upper position of the cabin connected to the heater control box.

Series Piping Note: This is a common method, but pipe resistance must be controlled to prevent water circulation blockage and frequent startup.
