EIA: trends in downsized engine design leading to increased demand for higher-octane gasoline

Green Car Congress

in August and September 2015—the highest share in more than a decade, according to data from the US Energy Information Administration (EIA). One significant trend is engine downsizing coupled with turbocharging. Turbochargers work by using a turbine driven off the exhaust gas to pressurize the intake air.

Ricardo’s “deep” Miller cycle concept: Magma

Green Car Congress

In its new report on downsized and boosted gasoline engine technologies ( earlier post ) the ICCT highlighted Ricardo’s work on an “extreme” Miller cycle concept with high (13:1) compression ratio (CR) and central direct injection in a downsized boosted engine. A long exhaust stroke then extracts maximum efficiency. Resources.

Review of research suggests inconclusive support for fuel consumption benefits of catalyzed EGR

Green Car Congress

Conflicting evidence does not support making a firm conclusion on the fuel consumption benefit of catalysed Exhaust Gas Recirculation (EGR), according to a review of current studies by a team at the University of Bath (UK). According to the review, the conversion of HCs, CO, and NO in the exhaust gas by the catalyst can result in up to a 4.5%
