Why is the Sylphy not suitable for natural gas combustion?
1 Answers
Sylphy cannot use natural gas as fuel because the engine will report an air flow meter fault when burning natural gas. The following are specific details about the air flow meter: 1. Function: The air flow meter measures the volume of fresh air and the intake air temperature entering the engine intake manifold. The ECU uses this information to adjust fuel injection quantity, limit smoke emission, and control the EGR valve opening. 2. Installation position: It is installed on the engine intake pipe, behind the air filter. 3. Working principle: Several electronic components are integrated on a ceramic substrate. During normal engine operation, the diaphragm is first heated. When fresh air flows through the sensor, it carries away some heat. The ECU then controls the Wheatstone bridge on the diaphragm to replenish the heat, causing a change in the electrical signal. When this signal is transmitted to the ECU, the ECU calculates the intake air volume based on this change.
