A smaller 14-module "Standard" battery, RPO EW2 is available for both front- and all-wheel drive models; the curb weight decreases by 520–700 lb (240–320 kg) with the "Standard" battery; [1] [2] estimated capacity of the "Standard" battery is 121 kW-hr. The Zevo 600 is capable of recharging at rates of up to 120 kW (DC) or 11.5 kW (AC).
It allows a V6 or V8 engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy. Estimated performance on EPA tests shows a 5.5–7.5% improvement in fuel economy. [1] GM's Active Fuel Management [2] technology used a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine.
The vast majority of vehicles manufactured after 1987 are fuel-injected: the injectors and high-pressure fuel pump immediately cease supplying fuel to the cylinders when the ignition is switched off. If the injector is damaged or dirty, a small amount of fuel can enter the chamber and be ignited, causing a sputter or two after the engine is ...
