At this year's IAA motor show in Hannover, Scania shows off two new, powerful biogas engines, among other things. This goes along with Scania's announcement of a big investment in tank solutions for gas vehicles earlier this year. The new 13-liter engines have 420 or 460 horsepower and cover a large part of the European truck market that needs higher outputs, such as long-distance vehicles.

Biomethane made locally for trucks is getting much attention because people want to get away from natural gas and reduce carbon emissions in road transportation. From the source to the wheels, biomethane can reduce CO2 emissions by up to 90%. All companies can choose biomethane-based solutions because they have powerful engines and tanks with longer ranges than ever before (there are tanks for both CBG and LBG).

Stefan Dorski, Senior Vice President and Head of Scania Trucks, says that long-haul tractor combinations weighing 40 tons can now travel up to 1,400 km on liquid biomethane.

He says that as the number of gas stations grows quickly, trucks with gas engines have become a strong alternative for customers who want to stop using fossil fuels and lower their CO2 footprint.

Scania's plan to reach its science-based goals of reducing CO2 emissions from customers' use of Scania products by 20 percent by 2025, with 2015 as the base year, is largely based on gas vehicles. Scania says that electrification and making combustion engines use less fuel will not be enough. All options must be used to reach both the company's own goals and the goals set out in the Paris Agreement.

The new biogas engines are based on the 13-liter gas engines that Scania has been making for a long time and are very popular. By making them more powerful and getting them ready for upcoming legal requirements, Scania is making it clear that it wants to grow in the gas vehicle market and emphasize sustainability.

The fuel and air in the new biogas engines burn up completely, so there is no need to add diesel or AdBlue. Spark plugs, just like gasoline engines, are used to start the engine. On their way into the combustion chamber, gas and air are mixed in the intake pipes.

Scania's latest Opticruise gearboxes (G25), which automatically shift gears, work with the new 13-liter gas engines. The driver can change gears quickly, safely, and almost without stopping.

The performance of the new engine family is due, in part, to the use of double overhead camshafts and Scania Twin SCR, a system that adds AdBlue in two stages to make the after-treatment system work better. The Scania Compression Release Brake is an advanced engine brake system that can be added to the new engines as an option.
