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. But efi has a broader powerband and superior cylinder to cylinder fuel distribution.
Efi Vs Mpfi Vs Gdi How Electronic Fuel Injection Technology
Efi vs carb 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. Carb tuning is hands on efi tuning can be over the internet. 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. Efi engines can sit for six months then start like they ran yesterday. Single plane intake carb vs. 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.
Same goes for the valve clearance adjustment. Carbs always have fuel exposed to air in the bowl. Getting the efi id prefer ill have to go with the better price and carb. Efi rpm carb af efi af 3000 11 12 3500 114. A carbs pressure differential atomizes the gas a lot better than spraying fuel through an orifice. 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.
But carbs only cost 200 compared to 1000 for efi system and programming hardwaresoftware. Efi can compensate for most any change in weather conditions. Carburetor vs fuel injection. Leave it sit six months and you are going to need tools. Upgrading to efi for small engines evens out performance issues and provides more power. Better starting more power better throttle response better fuel economy and you wont have plugged up carburetor jets to deal with anymore.
If it comes down to not getting as good of a deal vs. The carburetor is currently much less expensive than the electronic fuel injection systems. Emissions and fuel economy. Again carburetor performance relies on so many different variables from throttle position to air concentration that the performance can be erratic. 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.
Efi systems consistently deliver higher levels of gross horsepower than carburetors. However carburetors do last longer than fuel injection systems and are favored in motor sports. Carburetors versus electronic fuel injection efi. Building a stroker small block with ls like reliability.
