In many new energy models we are familiar with most of the hybrids to oil-electric hybrid, plug-in hybrid-based, compared to only oil or electricity, these hybrid models have higher power and economy, but in the hybrid era is not only oil / electric hybrid, the fourth generation of Geely Emgrand has brought us a new choice in addition to oil-electric hybrid, it is Emgrand "alcohol electric" hybrid vehicle.
At present, the use of methanol as fuel models on the market is not nothing, but the use of methanol and electricity as a hybrid drive of the model Geely Emgrand is indeed a precedent, and the fourth generation of Emgrand is the latest Thor hybrid technology of Geely, using methanol instead of gasoline to achieve lower car costs and lower emissions, but also to solve the methanol fuel compared to gasoline low endurance and weak power and other issues, then we will go straight to the theme to see how the fourth generation of Emhouol electricity performs.
01
Introduction to powertrains
In terms of power, Emgrand is equipped with a new generation of 1.8L alcohol-electric hybrid engine with a maximum power of 95 kW, and provides both 47L methanol fuel tank and 10L gasoline tank (only used for ignition), this engine adopts 12.5 high compression ratio design, with low friction technology, thermal efficiency of 41.5%; its use of DHT hybrid electric drive transmission, with 40% energy saving rate and 4920N·m differential design output torque, transmission efficiency of up to 97.5% In terms of batteries, 1.83kWh large-capacity high-performance ternary lithium batteries were selected, with a peak power of up to 65kW. In terms of economy, the alcohol-electric hybrid officially gave a 100-kilometer alcohol consumption of only 9L, according to the current price of methanol fuel is about 2 cents per kilometer.
02
Everyday driving
Emgrand alcohol electric hybrid is mainly based on methanol fuel as the main driving force, but within 50km/h at low speed can be fully driven by electricity, but it will also judge the timing of engine intervention according to the size of the power demand, and in our experience, we also found that the speed of daily driving under the acceleration pedal can be controlled in the case of 40-50km/h pure electric driving, and the low speed when driven by a separate motor can fully meet the needs of transportation. The timing of the engine intervention control is quite reasonable, in the case of overtaking on the uphill and other cases it will intervene in the work, the electric machine and the engine start at the same time, of course, if the battery is low in the case of the engine start will be more frequent to ensure sufficient power, from the actual experience although the capacity of the battery is not large, but the engine start when the recharge is almost equal to the use of go, so in fact almost will not occupy too much 1.83kwh of reserve power.
03
Drive at high speed
In the case of high-speed driving, the logic of this hybrid system is also very good, the speed is stabilized at 100km/h after the dashboard output table is only maintained within 10% or even lower, high-speed overtaking when the power output only needs about 30% There is a very obvious power outbreak, and with the help of the motor, the weakness of the methanol engine power is completely solved. At the same time, the effect can reach 1.5T power or even higher under the power, and in the case of high-speed cruising, the engine can be started when needed, and the fuel economy and mileage will be greatly improved.
04
Three driving modes
Emgrand electromix with three driving modes to switch, standard, economic and sport, these three modes are mainly to control the force and response speed of the accelerator pedal, the high power demand of the sport mode engine intervention will be more frequent, on the contrary, the economic mode start is reduced, and the heavier the throttle, the smaller the feeling of wanting to go to aggressive driving, so the driving mode is a good understanding.
05
There is basically no difference between the alcohol and gasoline versions
In terms of appearance and interior, the Emexol Electric Edition only carries the M100 alcohol electric logo on the body, and there is no obvious difference in the shape. In addition, the biggest difference in the interior is the instrument panel design, the right side is the speedometer, the left side is the total power output meter of the motor and the engine, and the green below the blue scale is the energy recovery level, which can be switched by the gear lever.
The following is mainly to solve some of the doubts about this model, the first methanol car and gasoline car driving experience is almost the same, although methanol is lower than the energy efficiency of burning gasoline, but the addition of the motor has made the power and endurance have been significantly improved, so the alcohol model compared to the oil-electric hybrid in driving there is no difference, almost the same. In addition, the two fuel tanks in the car are methanol and gasoline, not plugged in. The gasoline tank is only 10L, it is used for engine start-up only, and the real thing to burn is methanol. If 47L of methanol fuel is consumed, 10L of gasoline will replace the fuel as an emergency treatment.
06
epilogue
This time, we also carried out the actual measured alcohol consumption of Emgrand alcohol electricity, After driving 110km to fill up methanol fuel for 10.82L, 100 km alcohol consumption is only 9.8L, equivalent to 3.09L 100 km of methanol price, Dorsett Alcohol electricity per kilometer is only 3 cents, this time we did not test the endurance performance of this car, after all, methanol endurance is much lower than gasoline, but there is a motor to join believe that it will get a good balance, this aspect has the opportunity to get a test drive after the detailed introduction; I have to say that the alcohol power model is indeed higher in terms of technical needs, and need to add gasoline as a starting energy, the complexity may also be the reason why most manufacturers do not want to try in depth But if it can really be promoted on a large scale, there will be unimaginable changes in price and emissions, this is a certainty.
