Fuel injection because it can be more precisely controlled results in more efficient use of fuel reduced fuel consumption and fewer emissions which is the main reason it began to replace the carburetor in the 1970s. Again carburetor performance relies on so many different variables from throttle position to air concentration that the performance can be erratic.
Harley Electronic Fuel Injection To Carburetor Conversion
Efi vs carb reliability. Better starting more power better throttle response better fuel economy and you wont have plugged up carburetor jets to deal with anymore. Carbs always have fuel exposed to air in the bowl. Efi engines can sit for six months then start like they ran yesterday. Carburetors are also much simpler to install than fuel injection systems because there are no electrical components or return lines to the fuel tank. From a performance standpoint it all depends on what you want. Upgrading to efi for small engines evens out performance issues and provides more power.
Getting the efi id prefer ill have to go with the better price and carb. The carburetor is currently much less expensive than the electronic fuel injection systems. Building a stroker small block with ls like reliability. Those that cannot be automatically compensated for by the ecm can be easily reprogrammed by pc or laptop computer in just minutes without getting your hands dirty. A carbs pressure differential atomizes the gas a lot better than spraying fuel through an orifice. Leave it sit six months and you are going to need tools.
Carb tuning is hands on efi tuning can be over the internet. Single plane intake carb vs. Carburetor vs fuel injection. To view the efi version cub cadet efi with a price tag of 199900 it is 300 more than its carbureted version which is not a lot of money for the performance gains you will receive. However carburetors do last longer than fuel injection systems and are favored in motor sports. But efi has a broader powerband and superior cylinder to cylinder fuel distribution.
Ive successfully disassembled and cleaned the carb in the fh770d kawasaki i have now so im comfortable with the carb even if its not my first preference. Efi systems consistently deliver higher levels of gross horsepower than carburetors. Efi rpm carb af efi af 3000 11 12 3500 114. If it comes down to not getting as good of a deal vs. Same goes for the valve clearance adjustment. Emissions and fuel economy.
But carbs only cost 200 compared to 1000 for efi system and programming hardwaresoftware. The carb may outperform efi over a certain range of conditions efi is probably better over a wider range and will accommodate altitude and weather conditions better. Carburetors versus electronic fuel injection efi. Efi can compensate for most any change in weather conditions.
