Understanding Carburetors and Throttle Bodies: A Deep Dive

Before diving into the specifics of WD-40 Specialist Carb/Throttle Body Cleaner, it’s essential to understand the roles of carburetors and throttle bodies in an internal combustion engine. While carburetors are becoming less common in modern vehicles (replaced by fuel injection systems), they are still prevalent in older cars, motorcycles, and small engines. Both components are responsible for regulating airflow into the engine, a crucial factor in the combustion process.

Carburetors: Mixing Fuel and Air

A carburetor mixes fuel and air in precise proportions to create a combustible mixture. It utilizes a venturi effect, where air flowing through a narrowed passage creates a vacuum that draws fuel into the airstream. The resulting air-fuel mixture is then delivered to the engine’s cylinders for combustion.

Throttle Bodies: Controlling Airflow in Fuel-Injected Engines

In fuel-injected engines, the throttle body controls the amount of air entering the intake manifold. A throttle plate, controlled by the accelerator pedal, opens and closes to regulate airflow. The engine’s computer (ECU) then determines the appropriate amount of fuel to inject based on the measured airflow.

The Impact of Dirt and Deposits

Over time, carburetors and throttle bodies can accumulate deposits from fuel, oil, and environmental contaminants. These deposits can restrict airflow, disrupt the air-fuel mixture, and lead to a variety of performance problems, including:

• Rough idling
• Poor acceleration
• Stalling
• Reduced fuel efficiency
• Increased emissions

Regular cleaning is essential to maintain optimal engine performance and prevent these issues. That’s where WD-40 Specialist Carb/Throttle Body Cleaner comes in.
