Do EFI motorcycles really cost gas? Why are some models less powerful than carburetors?
I'm a knight to share.
EFI motorcycles have been popular for many years, but there are still riders who do not know much about this "species", and always miss some carburetor models, thinking that EFI motorcycles not only cost fuel, but also have good power.
But is that really the case?
I don't think so. Although some phenomena are also traceable, they are more self-indulgent and point-to-point, which is purely personal misjudgment or improper operation.
1.Do EFI motorcycles really cost gas?
I can tell you responsibly that as long as you choose the regular products of the first-line manufacturers, the fuel consumption of the EFI motorcycle is significantly lower than that of the carburetor model, and the larger the displacement, the more obvious this phenomenon is.
Of course, even if it is an entry-level small displacement, this is true both in terms of data performance and actual feelings. For example, the fuel consumption of a 110cc bending beam car equipped with a carburetor is basically 1It is about 7L, but the Honda CC110 equipped with the latest EFI system can be as low as 146 liters.
Another example is our more common carburetor 150 cc straddle motorcycle, and the fuel consumption will generally be 2 per 100 kilometersIt is about 5L, but most models with EFI fuel supply system can come to about 2L, and some models are even lower.
There are many more examples like this, and the reason is that the EFI motorcycle belongs to the precision active fuel supply system, which can adjust the mixture ratio and fuel supply in real time according to the engine temperature, speed, combustion status and other information, so as to achieve the purpose of saving fuel. The carburetor model does not have this ability, and it is basically an extremely simple fool-like oil supply state.
There will definitely be voices of rebuttal here, thinking that their EFI motorcycles are not fuel-efficient, and they are definitely oil tigers in other people's mouths.
In fact, this is normal, because the vehicle you choose does not have the characteristics of fuel economy, and if it is equipped with a carburetor system, it is likely to be more fuel-efficient than it is now. Therefore, the fuel consumption performance of some models is not caused by the replacement of EFI system, but its own fuel economy is relatively average.
2.Why are EFI models weakly powered?
This phenomenon mainly appears in some entry-level road models, especially some models that have transitioned from the China III era to the China IV EFI era.
The main reason for the decline in power of this type of model is actually not the problem of the EFI system at all, it is more caused by its own tuning and the thermal efficiency of the engine itself.
When an engine requires a large amount of flammable gas mixture to exert its proper power, it is actually a representative of low energy. Because once its rations are deducted, such models will instantly lie on their stomachs, and they will not be able to give full play to the advantages of power at all.
In fact, most of the transitional road car engine is basically in such a state, its so-called strong power is exchanged for high fuel consumption, once the proportion of oil and gas in the combustible mixture is reduced or the fuel supply is reduced, the relatively backward function of such models will be prone to disadvantages. It simply can't achieve the balance of fuel economy, power and power, so some models will be eliminated.
Of course, there will be reasons for the power drop, the emission blockage, etc. But to sum it up, it can be summed up in one sentence - their technology is too old, and they are not suitable for EFI systems at all, and they are completely out of service.
To sum up, whether it is theoretical or practical, the EFI system must be the most advanced fuel supply system in the evolution of the internal combustion engine, which not only has good low-temperature starting performance, but also can effectively reduce fuel consumption, and it will be easier to make the relationship between power and fuel consumption more balanced.
Otherwise, it would not have been able to completely replace the carburetor as the mainstream fuel supply system. As for the high fuel consumption of some models, the power decline, purely caused by technical reasons, it can only be regarded as an individual or special case, and does not represent the entire EFI fuel supply series, not to mention that EFI is also divided into three, six, nine and so on, not the same level. So what brands of EFI systems do you know?
