At the 31st Vienna Engine Symposium end of April 2010, German automotive technology company MBtech Group showcased an innovative natural gas combustion engine for medium-duty commercial vehicles. Commencing the project with a blank canvas the company is developing a compressed natural gas (CNG) driven in-line combustion engine with a 6 liter capacity and turbocharging especially for medium duty (MD) commercial vehicles.
The engine must fulfill particularly strict requirements: in comparison to other current six cylinder diesel engines for MD vehicles it should be considerably more compact and lighter while also offering significant advantages with regard to mechanical friction loss.
At the same time MBtech’s engineers have set themselves the goal of achieving at least the same power and torque ratings despite running on CNG and having two cylinders lessMBtech says that as a result of the Lambda 1 fuel-air relationship the four-cylinder CNG engine is also prepared to fulfill the upcoming, stricter exhaust gas regulations.
The combination of the innovative lightweight design and operating concept of the four-cylinder engine will enable goods to be transported commercially in a more environmentally friendly and cost-effective fashion in future, the company says.
