Understanding Carburetor and Throttle Body Cleaning: A Deep Dive

To fully appreciate the benefits of WD-40 Specialist Carb/Throttle Body Cleaner, it’s essential to understand the role of carburetors and throttle bodies in your engine and why cleaning them is crucial.

The Carburetor: An Outdated but Still Relevant Technology

While modern vehicles primarily use fuel injection systems, many older cars and small engines still rely on carburetors. A carburetor’s primary function is to mix air and fuel in the correct proportion to create a combustible mixture that powers the engine. It achieves this through a series of intricate passages and jets. Over time, these passages can become clogged with deposits from fuel and oil, leading to:

Poor fuel economy
Rough idling
Hesitation during acceleration
Increased emissions

The Throttle Body: The Gatekeeper of Airflow in Fuel-Injected Engines

In fuel-injected engines, the throttle body controls the amount of air entering the engine. It consists of a butterfly valve that opens and closes in response to the accelerator pedal. Just like carburetors, throttle bodies can accumulate deposits, especially around the butterfly valve and throttle bore. This buildup can result in similar problems, including:

Unstable idle
Reduced throttle response
Decreased engine power
Check engine light activation

The Importance of Regular Cleaning

Regular cleaning of carburetors and throttle bodies is crucial for maintaining optimal engine performance, fuel efficiency, and reducing emissions. Neglecting this maintenance can lead to more serious engine problems and costly repairs down the line. A product like WD-40 Specialist Carb/Throttle Body Cleaner makes this maintenance task accessible and straightforward.
