Elio Addict
Well, not with the Elio but you can with other management systems.Given the light weight and the light engine of the Elio, the possibilities are huge. A battery that is able to repeatedly start a big engine could do quite some assisting in an Elio. The heavy duty motors/alternators get cheaper and better all the time. From my understanding though, a hydraulic belt tensioner is often needed and the whole set-up including the bolts and the flywheel must be set up to allow for higher forces as compared to regular starts. With the valves, I doubt that you can get them to stay closed throughout an engine cycle.
LOL... I was looking for an example and came across this:

But, here is the gist.. (it's got to be a wee expensive)
The 2016 Pilot features a new 3.5-liter, direct-injected i-VTEC V-6 engine with new two-stage Variable Cylinder Management (VCM) cylinder deactivation technology. For improved fuel efficiency, the 2016 Pilot will also include a stop start feature—Honda’s first non-hybrid application of this technology.
Honda VCM deactivates the cylinder by using its VTEC (Variable Valve Timing and Lift Electronic Control) technology to keep the intake and exhaust valves in the closed position to halt fuel supply. To deactivate a cylinder, the pin is moved hydraulically to disengage the rocker arm that pushes down the valves. In this mode, even though the cam pushes up the rocker arm, it has no effect and the valves remain closed.
Honda says that cylinder deactivation is effective in reducing fuel consumption for three main reasons:
- Eliminates pumping losses in the deactivated cylinders. Keeping the valves closed in the cylinder to stop fuel supply also prevents aspiration in that cylinder. This eliminates pumping loss—the air resistance incurred when the pistons pump intake and exhaust gases through the cylinder—which is the greatest source of resistance in engine operation. This is the main reason why deactivating the cylinders contributes to improved fuel economy.
- Reducing pumping losses in active cylinders. In 3-cylinder operation, the throttle is open wider. This makes intake easier for the active cylinders, reducing intake pumping losses for improved fuel economy.
- Reduced loss from valve operation. Because the valves are deactivated, losses are largely reduced, allowing the engine to operate more efficiently. This contributes to improved fuel economy.
