What happens if the c200l keeps the engine running while parked?

[LaSawyer]

Keeping the c200l's engine running while parked allows the coolant to continue circulating and dissipating heat. Purpose: Keeping the engine running while parked means leaving the engine idling after stopping the car. Generally, this is only necessary if the engine is overheating, as it allows the coolant to continue circulating and dissipating heat. Another scenario is when the battery is low on charge, requiring the engine to idle for a period to recharge it. Idle State: Idling is an operational state of a car where the engine runs in neutral gear. The engine speed during idling is referred to as the idle speed. Idle speed can be adjusted by modifying the throttle opening, among other methods. Idling means the engine is running but not performing work. The idle condition is when the engine operates without load, meaning the clutch is engaged, and the transmission is in neutral (for automatic transmission vehicles, it should be in Park or P position). For vehicles with a carburetor fuel system, the choke should be fully open, and the accelerator pedal should be completely released. The engine's idle performance significantly impacts emissions, fuel consumption, and comfort, making it an important metric for evaluating engine performance. During idling, the engine is disconnected from the drivetrain, and the accelerator pedal is fully released, meaning the engine only overcomes its internal resistance without outputting any work. The engine speed during idling is called the idle speed, which should not be too high or too low. Excessively high idle speed increases fuel consumption, while excessively low idle speed can cause instability. The lowest idle speed that ensures stable engine operation is considered the optimal idle speed.
