Scania's biogas portfolio for heavy-duty trucks is being expanded and improved with the launch of two new biogas engines. This move complements Scania's significant gas strategy, which was announced earlier this year by introducing various new gas tank solutions. The new 13-liter biogas engines produce 420 and 460 horsepower, respectively, meeting most European demand for high-performance engines, especially for long-haul trucks. Scania will also be exhibiting its industry-leading new super powertrain and super trucks at the IAA TRANSPORTATION, which will be displayed both within and outside the exhibition hall.
The need for locally produced biomethane for trucks is increasing significantly. One reason for this is the goal of making road transportation as emission-free as feasible and eliminating the use of fossil fuels. When considered from well to wheel, biomethane has the potential to reduce CO 2 emissions by up to 90%. The combination of powerful engines and tank solutions with extended ranges (biogas and liquid natural gas tanks) allows haulers to choose biomethane-based truck solutions.
"With liquefied biomethane in the tank, long-distance tractor units with a gross combined weight of 40 tonnes can now reach a range of up to 1,400 km," explains Stefan Dorski, Senior Vice President and Head of Scania Trucks. "With the rapid expansion of the filling station network, vehicles with gas engines have become a legitimate choice for clients who want to give up fossil fuels and lower their carbon footprint."
Scania's reliance on gas-powered vehicles is critical to meeting Science Based Targets ( SBTs ). This equates to a 20% reduction in total CO 2 emissions by 2025. The year 2015 acts as a jumping-off point. All methods must be employed to attain the high goals we have set for ourselves to achieve the Paris Agreement. As a result, Scania continues to rely on biomethane in addition to electrification and combustion engine usage reduction.
The new engines are based on Scania's proven 13-liter gas engine, which has been on the market for some years. Scania's increased engine power and adaptation to future regulatory needs demonstrate that the company is looking for a higher market share in the gas truck business, with sustainability at the forefront:
"From an economic standpoint, we see great potential in biomethane," Dorski says. "I am confident that customers will appreciate the benefits of biomethane given its newfound flexibility, efficiency, and range." Even places where gas used to play only a modest role are now realizing how much more appealing this fuel has grown in recent years. Compared to other options, operating gas-powered trucks is simple and does not compromise driveability, flexibility, or driver comfort.
True to Scania's gas legacy, the new gas engines use complete combustion of fuel and oxygen, with no diesel or AdBlue added. Before injection, the gaseous fuel is premixed in the intake manifold.
The finest potential driveability was an essential priority for Scania's engineers. The Scania Super's diesel engines established the standard in terms of performance and attributes. The most noticeable difference between a gas engine and an identical diesel engine is that the gas engine operates quieter and more smoothly.
Scania's automatic shifting system (G25) is used in conjunction with the new 13-liter biogas engines. As a result, the driver enjoys smooth gear changes and a high degree of driving comfort thanks to rapid and smooth shifting. The maximal torque of the new gasoline engines is comparable to that of diesel engines. And, like these, gas engines provide substantial fuel savings. Orders for the new biogas engines will be accepted in the third quarter of 2023.
In November of last year, Scania introduced a new line of 13-liter engines that can run on biofuels and standard diesel fuel. According to Scania, the new powertrain, which includes new engines, transmissions, and rear axles, should result in up to 8% fuel savings for long-haul clients. Independent journalists have now confirmed these data throughout Europe in multiple tests.
The new engine platform's higher performance is primarily due to double overhead camshafts and Scania Twin SCR, a system for double AdBlue injection that improves the efficiency of the exhaust after-treatment system.
The new biogas engines include an optional decompression brake for increased engine braking performance, as well as sophisticated services:
a) by establishing flexible maintenance intervals based on the actual operation
b) Scania ProCare with preventive replacement of critical parts
These Scania engines are based on a revamped platform built from the ground up. The new powertrain has received over two billion euros in investment.
This new range promises total fuel efficiency, compatibility with biofuels, positive overall economy, and a significant reduction in CO2 emissions for Scania customers who use internal combustion engines. The new biogas engines are suitable for a wide range of applications and contribute significantly to lowering CO2 emissions.
