CTI Mag: Further CO2 savings thanks to Electric Transmission Oil Pumps


Conventional, mechanically driven oil pumps must provide the power required under maximum load at each speed in the transmission. In general, under real operating conditions these pumps waste not only valuable energy, but also material and space. Electric oil pumps, on the other hand, provide the power which is actually required at the load points. Further efficiency gains in the transmission are thus possible.

CTI Mag: Hydraulic Accumulator in Transmission Controls


Dual clutch transmissions offering disruption-free traction are in the portfolio of all well-known auto manufacturers. The hydraulic accumulator is the ideal solution to ensure that hydraulic actuations are as efficient as possible even at peak demand. Independent investigations have shown that the hydraulic accumulator makes it possible to gear components, such as the hydraulic pump for actuators, to reduced fuel consumption. This saves energy and reduces CO2 emissions. The hydraulic accumulator needs only about a sixth of energy of a conventional constant pump. Thus, the CO2 emission is reduced by up to 4 g/km.

Hybridisation via 48 V systems: The smartest way to reduce automotive CO2 emissions?


The only practical way for automobiles to meet strict CO2 reduction targets is through incremental powertrain electrification. But which concepts are most promising, and how do you get innovations into production fast? This is just one of the hot topics high calibre experts will be discussing at the 16th International CTI Symposium Berlin (4-7 December).

The quiet star: mild hybrids based on 48 V
Electric automobiles often grab the public’s attention, but have yet to break through. The most frequent objections are the high purchase price, and the lack of range and charging points.
48 V-based mild hybrids are different. Behind the scenes, this concept is gradually becoming the preferred candidate, particularly in terms of feasibility and cost-benefit ratio. The heart of the technology is a starter/ generator that can be added to existing powertrains with relatively little effort. This reduces the fuel consumption, and hence the CO2 emissions, of the internal combustion engine to a relative extent while offering drivers comfort features normally reserved for expensive high voltage technology. The existing 12 V system is integrated into the 48 V system, and is available in parallel. Continue reading “Hybridisation via 48 V systems: The smartest way to reduce automotive CO2 emissions?”

Interview Fritz Indra


Formula 1 Expert Fritz Indra: The Automotive Sector is Under Pressure.

The automotive sector is under pressure. Aside from all internal trouble a considerable part of the pressure in the industry is caused by legislation, Fritz Indra says. All car manufacturers are currently pushing electrification, which may also be a strategy to take the bull by the horns. But in the opinion of the Austrian engine designer and Formula 1 expert, the current trend towards the electric car should be regarded in a more critical way than it currently is the case. Especially with regard to climate protection, he says, because electric cars aren’t as clean as they are expected to be. Continue reading “Interview Fritz Indra”
