After each expansion cycle the heat exchange fluid is recovered from the exhaust and reheated to ambient temperature via a heat exchanger similar to a conventional radiator. Some of the heat that will inevitably escape down the exhaust will be converted into electricity using a thermoelectric generator (TEG). Earlier post. ).

The new six-cylinder in-line engine comes with an intelligent form of turbocharging: assisted by the ISG at start-off, the electric auxiliary compressor (eZV) guarantees immediate high torque when driving off and accelerating, bridging the time before the large exhaust turbocharger cuts in. Almost imperceptible restart of the engine.

There have been a number of concepts proposed to enable such VCR systems. Conversely, moving the center of the eccentric journal downward raises the compression ratio. In a 1976 SAE paper, Grundy et al. Two main types of variable compression ratio systems have been proposed over the years: continuous and two-stage. Earlier post.).

In the most-general terms, the term “advanced combustion regimes” is intended to encompass clean and highly-efficient, liquid-fueled combustion engines. Such engines may incorporate novel thermodynamic cycles, but should not simply involve regurgitation of existing concepts (e.g., Miller Cycle).

converted all vehicle efficiency measurements into vehicle energy efficiency (VEE, km/MJ) based on fuel energy densities reported in each study. This is because the ethanol component may affect the conversion efficiency of the gasoline component in a blend, that is, make an engine more or less efficient in its use of the gasoline component.

Omnivore lays the foundations for a novel and pragmatic vision of a variable compression ratio engine concept suitable for production. The two-stroke cycle, conversely, does not suffer from significant throttling losses and in many ways is a more natural fit for automotive use. Simon Wood, Technical Director of Lotus Engineering.

Gasoline engines can operate lean to improve fuel economy, potentially reducing CO 2 emissions significantly. The conventional three-way catalyst (TWC) is thus not an option for lean gasoline exhaust conditions. However, the lean-to-stoichiometric (L/S) time ratio defined the fuel consumption benefit available.

The concept ensures long term energy storage for delivering short bursts of power to the VTES supercharger during vehicle accelerations and to the SpeedStart stop-start device during engine re-starts. Conversely, short bursts of power can also be absorbed by the SpeedStart generator to recharge the battery during vehicle decelerations.
