A suitable combination of our advanced technologies allows us to demonstrate engine concepts with outstanding advantageous properties. Thus, we can implement the current mega-trends "downsizing" and "downspeeding". Also, future applications of engines with multi-fuel operation (like CNG / Gasoline) can exploit the full advantages of the respective fuel type or quality used.

Furthermore, we are working hard on future methods to improve the internal efficiency of internal combustion engines significantly.

MDC

The Meta Downsizing Concept (MDC) is a total engine design approach for an advanced and efficient engine targeting to small and compact vehicle classes. Compared to a conventional natural aspirated engine, the swept volume typically can be cut in half, and the number of cylinders is reduced from 4 to 2. The good thermodynamic efficiency of large engines is implemented in this way with smaller displacement. Our Meta Supercharger with a very compact layout provides high torque at low engine speed and thus potential for further efficiency by downspeeding. With the support of the Meta CRE-System, engines with small cylinder numbers can run smoothly at low engines speeds, even at very high specific loads.

For example, with a vehicle curb weight of 1050 kg using Meta MDC and CNG fuel, CO2 emission level can be lowered to about 69 g/km.

TVVH

Our fully variable mechanical valve actuation system (VVH) is an ideal complement for turbocharged downsized engines. The continuously control of intake valve lift and closing time allows throttle-less operation of SI engines at part load and optimal volumetric efficiency at full load. The gas exchange losses are minimized, and engine torque and throttle response at low speeds can be significantly improved. This is a crucial prerequisite for the use of the fuel economy potential of downsizing and downspeeding engines.

In addition, the intensive mixture preparation due to high inflow energy offers significant potential to optimize the combustion. Especially with alternative fuels such as natural gas (CNG) this can be used to improve the part load efficiency and catalyst heating strategy. Meta has demonstrated the potential of fuel consumption and emissions of TVVH technology through extensive dynamometer and vehicle tests.
