Volkswagen Shares Plans in Cutting Emissions


To address the dieselgate scandal, Volkswagen is planning a variety of powertrain technologies in order to meet CO2 requirements, most especially in North America, Europe, and China.


The company now puts climate targets as its main objective, starting with cutting on emissions. Some initiatives include a variety of hybrid, electric, and advanced combustion-engine technologies. With a 95g/km CO2 fleet average required for 2020 and much lower than that set for 2030, electrification of vehicles will be of utmost importance.


Volkswagen predicts 25% of its models will be battery-electric operated by 2025, with over 50% electrified compared to just 3% currently. Bio, synthetic, and synthetic natural gas is becoming the main topic of research.


Fast Plug-in Hybrids and Electric Cars


The electric vehicles from Volkswagen are currently e-Golf and e-Up, with the addition of Golf and Passat GTE plug-in hybrids. They plan to expand further on those in order to meet the milestones set. seven-speed DSG transmission with built-in 60bhp electric generator are presently in the current hybrids. Engineers are now toiling on creating a GTI prototype, which is dubbed the Golf GTE Performance, which has software upgrades that allow acceleration for electric models to unlimited speeds given the battery is sufficiently charged. Full-hybrid models will soon be supported by seven-speed DSG transmission after it enters production.


Improved Technology Cleans Up Diesel


Fixes on 2.0-litre, 1.6-litre and 1.2-litre engines are being implemented globally while recall of diesel cars in Europe is already 70% complete. The company has stated that recalled cars have been confirmed by independent testing to pass new Real Driving Emissions measurements, although some have been found to be damaged and polluting the air even more in worst cases.


A second selective catalyst reduction module may help reduce NOx when introduced into the exhaust system. new higher-pressure injection systems and combustion strategies will also be able to minimize NOx within the engines as well. New 48V electrical systems is also seen to greatly reduce NOx.


Petrol Technology Rework


The new 128bhp 1.5-litre TSI evo petrol engine is a revamped version of the existing engine which uses cutting-edge technology to improve fuel economy and emissions.


A variable turbine geometry turbocharger is equipped in the engine, which allows the highest compression ratio while it runs on a special Miller cycle operating regime. Combine those elements and you get flexible power delivery and great fuel consumption for all the vehicles.


CNG and E-Fuels


Compressed natural gas, or CNG, has been the main choice in Europe and is now being joined by bio-methane created from fermenting plant materials, with straw included. Bio-fuels are great as they are considered carbon neutral, which means plants can absorb them. Around 1800kg of straw can create 300kg of CNG, which can be a good source of power for Polo allowing it to cover 6200 miles. Volkswagen has been painstakingly working on creating bio-synthetic fuels for some time now. The said process combines CO2 with sustainably produced hydrogen in order to produce carbon-neutral synthetic liquid e-fuel. Engineers said it is worth every effort as it has immediate effect on both old and new engines.


Two Kinds of Mild Hybrid


Mild-hybrid electric vehicles, also known as MHEVs, is expected to become a normal sight in the coming years as 48V electrical systems are made even more common. Combining a 48V lithium ion battery and a 48V belt-integrated starter-generator, or BISG, allows the cars to recover and even store electric energy. This can help augment engine torque, save fuel, and improve response.


The Golf 1.5 TSI MHEV and an MHEV Plus are Volkswagen’s two prototypes. 15bhp BISGs are what can be seen on both models, while a 34bhp electric motor can be seen on the Plus. The Plus has an upper hand in such a way that it can regain energy as it coasts with the engine on halt, and even use electric-only power.
