It’s only when the car starts to run roughly that most drivers take a look at the RPMs. But what RPM should a car idle at, and how will you know if there’s a problem? A well-functioning air conditioning system is crucial for comfort during hot weather. However, excessive heat can strain the system, leading to reduced efficiency. To maintain optimal air conditioning efficiency, park in shaded areas when possible and consider using a windshield sunshade to keep the interior cooler. Regularly check and replace air filters to ensure proper airflow and cooling performance. Regularly service and maintain the air conditioning system to ensure optimal performance. Intake : The piston (green) is pulled down inside the cylinder (gray) by the momentum of the crankshaft (gray wheel at the bottom). Most of the time the car is moving along, so the crankshaft is always turning. The inlet valve (left) opens, letting a mixture of fuel and air (blue cloud) into the cylinder through the purple pipe. Compression : The inlet valve closes. The piston moves back up the cylinder and compresses (squeezes) the fuel-air mixture, which makes it much more flammable. When the piston reaches the top of the cylinder, the sparking plug (yellow) fires. Power : The spark ignites the fuel-air mixture causing a mini explosion. The fuel burns immediately, giving off hot gas that pushes the piston back down. The energy released by the fuel is now powering the crankshaft. Exhaust : The outlet valve (right) opens. As the crankshaft continues to turn, the piston is forced back up the cylinder for a second time. It forces the exhaust gases (produced when the fuel burned) out through the exhaust outlet (blue pipe). Power.
