In a direct injection engine, they noted, the cooling of the charge and consequent knock relief provided by the evaporation of the fuel is proportional to the fuel flow per unit mass of air. Further, the effect of charge cooling on reducing the rate of autoignition kinetics is amplified by the high sensitivity of ethanol. Anderson, J.,

Knock and fuel octane rating are becoming increasingly important due to many powertrain design trends including downsizing, downspeeding, cylinder deactivation, and hybridization. … The concept of an “effective octane number” calculates overall knock resistance of fuel in modern engines, including the effects of charge cooling.

Ford’s turbocharged, gasoline direct injection EcoBoost engines are targeted to play a significant near-term role in Ford’s efforts to reduce fuel consumption by enabling downsizing. Ford identified stratified-charge operation as an enabler to achieve such very retarded combustion timing. port fuel injected (PFI) V8 engine.

Were charging full-speed ahead before we know exactly what the investment is going to be, before we know whether we can make any money off it or not, before we know how many were going to sell," Lutz said. Lutz said lithium-ion batteries must be improved to hold a bigger charge and deliver the charge gradually. Red Herring ).
