Car heating primarily relies on the heat generated by the engine. When the engine is running, it produces heat, which is then transferred to the car's cabin through the heating system. If the engine is off, the heating system cannot produce new heat. However, residual heat from the engine can still warm the cabin for a short period after the engine has been turned off, but this heat dissipates quickly. For continuous heating, the engine needs to be running to continuously generate and transfer heat to the cabin. Some electric and hybrid vehicles use electric heaters that can operate without the engine running, but these systems draw from the car's battery and can reduce overall vehicle range.
Typically, a car's heating system requires the engine to be running. This is because the heating system often uses the heat from the engine's coolant to warm up the air that is blown into the cabin. However, some electric and hybrid vehicles can provide heat without running the engine. Additionally, some vehicles may have auxiliary heating systems that can provide heat when the engine is off. But generally, conventional cars require the engine to be on for the heating to work.
There are two effective methods for measuring engine RPM without a tachometer. The first involves using an app that analyzes sound frequencies to approximate RPM. By utilizing the smartphone's microphone. this app can detect engine sounds and calculate the RPM based on the noise pattern. Another practical approach is using reflective tape and a laser tachometer. This method involves applying reflective tape to the rotating parts of the engine and then using a handheld laser tachometer to measure the RPM by pointing it at the tape. The device sends a laser beam that reflects off the tape and calculates the RPM based on the frequency of the reflected signal. Both options offer solutions when a traditional tachometer is not available. but they may require calibration and verification of source accuracy based on a known RPM.
The duration for a check engine light (CEL) to turn off can vary based on the root cause and if the issue was resolved. Typically, if you address the fault (e.g., fixing a loose gas cap or replacing a faulty sensor), the light might turn off immediately or after several drive cycles - usually between 10 to 20 cycles or around 50 to 100 miles of driving. Vehicles have onboard diagnostics (OBD-II) that continuously monitor for anomalies. Once the problem is corrected, and the system no longer detects the issue after several drive cycles, it will automatically turn off the CEL. However, persistent or more serious issues will keep the light on until professionally diagnosed and resolved. It’s advisable to consult a mechanic for accurate diagnosis and repair to prevent potential long-term damage.
