Introduction to Carburetors and Fuel Injection
A carburetor is an older technology that relies on suction to pull fuel into the engine’s cylinders. It’s a mechanical system that has been around since the early 20th century, but it’s largely been replaced by fuel injection systems. Fuel injection, on the other hand, is a more modern technology that uses electronic signals to spray fuel into the engine’s cylinders. It’s a more efficient and cleaner way to supply fuel, which is why many modern cars have made the switch.
Design & Dimensions: Carburetors vs. Fuel Injectors
| Carburetor | 12-18 inches (30-45 cm) | 2-5 pounds (1-2.5 kg) |
| Fuel Injector | 2-5 inches (5-13 cm) | 0.2-1 pound (0.1-0.5 kg) |
Feature Comparison: Carburetors vs. Fuel Injectors
| Carburetor | Fuel Injection | Adjustments | Cost |
| Mechanical | Electronic | Difficult | $500-$1,000 |
Engine Specifications: Carburetors vs. Fuel Injectors
| Carburetor | Fuel Injector | Power Output |
| 100-200 horsepower (75-150 kW) | 200-500 horsepower (150-375 kW) | Up to 500 horsepower (375 kW) |
Price Comparison: Carburetors vs. Fuel Injectors
| Carburetor | Fuel Injector |
| $500-$1,000 | $1,000-$5,000 |
The Pros of Swapping a Carburetor for Fuel Injection
So, what are the benefits of swapping a carburetor for fuel injection? Here are a few:
- Improved Efficiency
- Reduced Emissions
