the 2013 Chevrolet Malibu ECO's eAssist arrangement is akin to a 2.4L Ecotec direct-injection four-cylinder agent and next-generation six-speed automated transmission. The 2.4L agent is able and lightweight, featuring dual-overhead cams, absolute injection, continuously capricious assimilation and bankrupt timing and cyberbanking burke control, as able-bodied as a failing aluminum butt block and butt head. It is rated at an estimated 180 application (134 kW) and is a alternative of the aforementioned agent that was accustomed as one of Ward's Ten Best Engines in 2010.
Along with the Ecotec 2.4L and six-speed transmission, the eAssist arrangement uses ability stored in the air-cooled, lithium-ion array to accommodate bare electrical addition in assorted alive scenarios, optimizing agent and manual operation. An avant-garde 115V lithium-ion array and latest-generation 15-kW motor-generator assemblage advice access ammunition abridgement through:
* Regenerative braking, which provides up to 15 kW of electricity to allegation the battery
* Providing up to 15 hp (11 kW) of electric ability abetment during added acceleration
* Using electricity instead of gasoline back stopped, with automated and bland agent start-stop functionality
* Aggressive ammunition absolute during deceleration bottomward to aught mph for added ammunition savings
* Intelligent charge/discharge of the high-voltage battery.
The eAssist arrangement captures up to 15kW of activity that would be commonly absent during braking and uses it to recharge the lithium-ion battery. The arrangement additionally shuts bottomward ammunition commitment in assertive deceleration conditions, added convalescent ammunition economy. While in ammunition shut-off mode, the motor-generator assemblage continues spinning forth with the agent to accommodate actual and bland abandonment ability back the disciplinarian presses on the accelerator. As the agent comes to a stop, the engine's start-stop action is alive back the motor-generator assemblage brings the agent to a bland stop to position it appropriately for a bland restart back the anchor is released.
A hill-assist arrangement captures anchor burden to advice accumulate the agent anchored back eAssist's start-stop action is activated on a abstinent or abrupt grade, acceptance the disciplinarian to advance added calmly from a stop.
Chevrolet Malibu ECO's eAssist ability backpack brings calm the lithium-ion battery, the chip ability inverter and 12V ability supply. It is amid in the trunk, abaft the rear seat. The electric motor-generator is army to the agent in abode of the alternator to accommodate both motor abetment and electric-generating functions through an agent belt-drive system. The motor-generator is a high-performance, bunched consecration motor that is liquid-cooled for added achievement and efficiency. An electric fan cools the ability pack, cartoon air from a aperture amid abaft the rear seat.
Thanks to eAssist technology, which additionally enables a numerically lower final drive ratio, the Chevrolet Malibu ECO can biking as abundant as 550 afar amid fill-ups, admitting accepting alone a 15.8-gallon gas tank.
