Researchers from Michigan State University have been awarded $2.5 The WDG also can reduce carbon dioxide emissions by as much as 95 percent in comparison to modern internal combustion vehicle engines. Swissauto Wenko AG of Switzerland produces a modern version of the Comprex—the Hyprex—designed for small gasoline engines.

A team at the Engine Research Center (ERC), University of Wisconsin-Madison has demonstrated the viability of reactivity-controlled compression ignition (RCCI) in a two-stroke engine. However, RCCI experiments with gasoline and n-heptane (higher volatility) proved to be successful. Earlier post.)

TSCi combustion minimizes heat loss to the cylinder walls and in the exhaust. The company currently is optimizing the system for use in modern high-compression diesel architecture engines, near-term running on gasoline while longer-term utilizing advanced low-carbon fuels. As a comparison, the 2010 Prius delivers 51 mpg US (4.6

A variation of the approach could be used for gasoline PHEVs.) Problems due to aged fuels can occur at the fuel pump, injection systems or exhaust aftertreatment. For purposes of comparison, the FTIR signal was measured, which correlates with the sensor signal. A paper on their work appears in the journal Fuel. Resources.

To keep the maximum power and thus satisfy the consumer’s drivability demands, the engine is highly supercharged by a turbocharger—which exploits the exhaust gas enthalpy as an energy source, and which boosts the to the desired levels. This also halves frictional losses and increases the engine’s average efficiency. Dönitz et al.

In 1975, General Ernesto Geisel, then-president of Brazil, ordered the country’s gasoline supply mixed with 10% ethanol. The level was raised to 25% over the next five years, which was intended to maintain a constant Brazilian gasoline supply for an ever-increasing demand. These were arguably the first flex-fuel vehicles.

GDCI engine was significantly better than advanced production spark injection gasoline engines, and comparable to very efficient hybrid vehicle engines at their best efficiency conditions (214 g/kWh). This early work established that gasoline-like fuels with high resistance to autoignition are preferred for PPCI. Earlier post.)

A team from Carnegie Mellon University (CMU) has characterized the intermediate volatility organic compound (IVOC) emissions from on-road gasoline vehicles (LDGVs) and small off-road gasoline engines (SOREs). All LDGVs were tested using commercial summertime California gasoline and the cold-start united cycle.

In a paper in the journal Fuel , researchers at Tianjin University report on the use of cooled EGR to improve the overall performance of 2-methylfuran (MF) as an alternative fuel. When the cooled EGR rate reached 15%, the NO x emissions from the gasoline at a compression ratio of 10 was reduced by about 20.6 —Pan et al.

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. Though the PHEV combines the two types of energy and power, it is not merely a temporary “transition” between gasoline and diesel cars to pure electric cars. by Professor Andrew Alfonso Frank. It is much more than that.
