With the development of the automobile industry so far, the concept of automobile consumption is more and more close to the concept of environmental protection, and traditional internal combustion engine vehicles will gradually be eliminated. However, many industry experts still believe that in order to meet the requirements of future carbon emission policies, the market demand for hybrid drives will grow. Based on this, MAHLE has newly developed a fully integrated modular hybrid drive that meets the various application needs of automobiles with personalized customization features.
It is reported that this fully integrated, plug-in "MAHLE Modular Hybrid Powertrain" (MMHP) is lighter, more compact and more cost-effective than existing hybrid technologies. It reduces the requirements for internal combustion engines and spawns a cost-optimized "dedicated hybrid engine" (DHE) that uses many innovative technologies from the passive "Mahler injection ignition system" (MJI®).
"According to EU regulations, the average CO2 emissions of new car companies must be less than 59.4g / km by 2030, and there is not enough time for new models and new technology development. Therefore, electrification is an important choice in the industry for emissions standards Approach. "Dr. Martin Berger, Director of Mahler Powertrain Division focusing on engineering services, said," The advancement of hybrid technology is key to meeting future emissions targets for the entire automotive industry. MMHP provides OEMs with Quick off-the-shelf solutions make things easy all at once. "
In fact, the MMHP uses a dual-mode hybrid power system, which not only makes the vehicle's driving mode more flexible, but also brings better NVH performance. Specifically, the car can be driven as a pure electric vehicle when the power is sufficient; when the power is low and the driving speed is slow, it can be switched to the series mode; when the vehicle speed is high, the internal combustion engine can directly drive the wheels in parallel.
It is understood that according to different application requirements, this hybrid drive is available in single-speed, two-speed and four-speed transmissions, which can be used in lower to medium-sized cars to large SUVs. In the first stage of the test, the fuel consumption level of the hybrid drive vehicle equipped with MAHLE reached 207g / kWh. In the future, if combined with the active MJI® system, it will not be difficult to achieve a fuel consumption level of about 195g / kWh in the simplified operation mode. It is worth mentioning that the weight of this hybrid powertrain is comparable to that of a four-cylinder gasoline engine equipped with a six-speed manual transmission, and the specially designed engine can save up to 30% of the cost.
