Diesels are in decline Not so fast, says Volkswagen.
Volkswagen might be ready to enter the electrification age with its I.D. Volkswagen may be moving into the electrification era with its I.D. production models and many hybrids, but this doesn’t mean that the diesel-powered combustion engine is going extinct. The EA288 Evo, a new four-cylinder turbodiesel engine with a 2.0-liter displacement, was unveiled at the 2018 Vienna Motor Symposium in Austria. It will power the VAG models tomorrow.
This is the debut of a hybridized Diesel. The 2.0 TDI will work with a mild hybrid setup that includes a 12-volt belt starter generator, a lithium-ion battery charger, and a 12-volt belt starter. This new arrangement will not only reduce fuel consumption and drive down emissions but also increase comfort in the cabin. VW focuses on the main difference between the four-cylinder diesel engine and older TDI units. This is represented by “extremely low emission in all driving cycles”.
The EA288 Evo will offer power in a variety of specifications, ranging from 136 horsepower (100 kW), up to 204 horsepower (150 kW), which is a nine percent increase in power and torque. Audi is the first to use the turbodiesel engine in cars with a longitudinally mounted drivetrain. It will be used by the VW core brand, as well as the other marques of the group such as Skoda or SEAT in their MQB-based vehicles.
The mild hybrid system was created by VW engineers. They also tweaked the combustion process to increase efficiency and speed up the turbocharger’s response time. The diesel particulate filter is now more efficient and has been resized.
The EA288 Evo has more positive news. It is lighter than its predecessor, and suffers from fewer heat and frictional losses. VW continues to say that the new diesel meets the stricter standards of the Worldwide Harmonized Light Vehicles Test Procedure (WLTP), which will soon replace the obsolete New European Driving Cycle (NEDC).
VW also spoke at the Vienna Motor Symposium about its 48-volt mild hybrid system, which will be used in the next generation Golf. It is expected to arrive in the second quarter of 2019, with the goal of “drastically reducing consumption and emissions.”
The company’s 1.5-liter TSI Evo 1.5-liter engine was engineered to run on compressed natural gas. Based on the 1.5 TSI ACT BlueMotion , the 1.5 TGIEvo produces the same 130 hp (96 kW) as the . The CNG-running engine, which will be available later in the year, uses the Miller combustion process. The Golf equipped with the dual clutch automatic transmission will require 3.5 kg of compressed natural gas per 100 km (62 miles). It will also be able to travel up 490 km (304 mi) on CNG.
