Early versions of direct injection employed a stratified injection strategy which included late fuel injection and charge air motion to produce a stoichiometric air/fuel mixture in the vicinity of the spark plug and, thereby, avoid pumping losses from the need to throttle the engine at light load. —Maricq et al. Click to enlarge.
Shift responsiveness has improved through downsizing of the pulley and reduction of inertia by 40%. It also achieves greater thermal efficiency, resulting in high output, due to a reduction in energy loss associated with exhaust and cooling systems, the movement of mechanical parts, and other aspects.
“People downsize cars, not expectations. Customers are increasingly making decisions to downsize driven by lifestyle and fuel economy. We’ve learned that when customers downsize, they still want the amenities they’ve become used to in larger vehicles.”
Cylinder deactivation: deactivates the intake and exhaust valves and prevents fuel injection into some cylinders during light-load operation. Variable valve timing: alters the timing or phase of the intake valve, exhaust valve, or both, primarily to reduce pumping losses, increase specific power, and control residual gases.
