Speaking of VM, we must first understand the world-famous Italian diesel engine manufacturer VMMotori. The company has always been in a leading position in diesel engine technology, and its products have been applied to mature models such as Alfa Romeo, Chrysler Rover and Land Rover Defender.
VM engine, which combines the advanced technology of Europe in 2 1 century, is famous for its strong power. Since 200 1, it has been put into the European market in large quantities and widely used in various SUVs, MPVs, LDVs and cars. VM diesel engine adopts the latest electronically controlled high-pressure rail fuel injection system from Bosch, Germany, and adopts leading technologies such as intercooling and supercharging, cooling exhaust gas recirculation (EGR), variable geometry turbocharger (VGT), dual-shaft balance, four valves and four cylinders, and double overhead camshaft.
Strong power is its biggest advantage, and it also effectively improves fuel efficiency. It has the advantages of "two highs and three lows", that is, high power, high torque, low fuel consumption, low emission and low noise, which conforms to the development trend of diesel engine energy saving and environmental protection, and is especially suitable for domestic SUVs to completely get rid of the "slimming" demand of "oil tiger" hats.
VMR425 diesel engine has the strongest dynamic performance index among domestic diesel engines with the same displacement: it can emit 340N in the speed range of 2000-4000 rpm. M, the maximum power can reach 105KW. At low speed, the torque is large, and the speed of the whole vehicle is good. At low speed, it can generate greater power and bring obvious push-back feeling. Whether starting or accelerating, urban road conditions or off-road sections can bring a relaxed sense of motivation.
It is obviously superior to the traditional Isuzu supercharged diesel engine 4JB 1(70KW) widely used in domestic SUVs with the same price.
In addition to the above advantages, VMR425 engine flexibly and accurately controls the fuel through ECU computer, which improves the combustion efficiency by 8% compared with the traditional supercharged diesel engine, reduces the fuel consumption by more than 10% compared with the traditional supercharged diesel engine, and effectively reduces the vehicle cost. The fuel consumption at 60km is 5.5L/ 100 km, and the comprehensive fuel consumption is only about 7L/100 km. If you travel 30,000 kilometers a year, it will save 400 liters of diesel compared with the traditional supercharged diesel engine.
In addition, the cylinder structure of VMR425 diesel engine is tunnel type, which is characterized by durability and long service life, and users can enjoy strong power continuously throughout the service life.
There are also more affordable places. With the adjustment of the new automobile consumption tax, the displacement of VMR425 diesel engine is no more than 2.5L, and its consumption tax is 9%, which is obviously less than the 2.8TC(4JB 1) (consumption tax is 12%) of the current popular SUV with the same price, thus reducing the cost of the whole vehicle and the cost of car purchase for consumers. When the fuel tax is implemented in the near future, vehicles equipped with VMR425 low fuel consumption engine will also greatly reduce the fuel tax paid by consumers.
GW2.5TCI is an intelligent fuel-saving diesel engine with high-pressure rail technology jointly developed by Great Wall Company and Bosch Company of Germany. It has the advantages of economy, quietness and strength. The power is 80kW, the torque is 300n·m, and the comprehensive fuel consumption per 100 kilometers is only 5.0L, which is the lowest among similar models. The power of 2.5L reaches the fuel consumption of 1.5L car. In the 2009 Urban Fuel Saving Extreme Challenge held by CCTV and China Automobile Federation, half a tank of oil was used to run to Russia, and 40L oil ran 1400 kilometers. The average fuel consumption per 100 kilometers is less than 3L.
