Looks perfectly straight to me. Of course, I’m also the type of person who allegedly [ahem! allegedly] agree with everything.

Nope it’s not.

It would probably make more sense to use a valve train disabling system while turning off the fuel injector to the designated cyl. V8’s and 4cyls share the same crankshaft design ( rod journals) so you would have the option to use a beefy 4 or super 8. By holding the intake and exhaust valves open during cyl disable (180 degrees out for balacing issues), the engine would save fuel and also become more efficient due to almost no resistance. By holding the intake valve open on decel, you have created an engine brake (search jake brake). The L62 disabled fuel only so in 4 mode you still have 4 cyl resistance on compression stroke.

maybe after a certain time only manual light switch use would be in effect.heh.

I did not know about the Cadillac engine, but it sure would be nice to be able to manually control what you want also…

This is a great idea but you would need some sort of bypass for sleeping. I considered an idle timer but that would create problems (book reading etc).
Perhaps a signal strength adjustment for point of entry like a super ranged magnetic proximity switch. Perhaps a heat signature trigger with audio bypass? No triggers required…

Food for thought:
Japanese engine manufacturers have been using low horsepower engines that get 45+ mpg for years but dont really fit the US market due to poor driveability. In the early 90’s they had come to the conclusion that a variable internal engine component or electric hybrid would be the best solution until hydrogen power was cost effective. From prechamber intake systems to variable valve timing, it wouldn’t make billions of r&d dollars wasted meeting epa emissions regulations.

Variable valve timing uses a “wedge” that makes the camshaft seem larger by using oil pressure to move between the valve and valvetrain. Oil pressure rises with rpm making the lift and duration change.

In 1981 Cadillac introduced what became the most notorious engine in the company’s history, the V8-6-4 (L62). The cylinder deactivation system that would shut off fuel to two or four cylinders in light-load conditions like highway cruising, then reactivate them when the throttle was opened. A dashboard “MPG Sentinel” gauge could show the number of cylinders in operation, or instantaneous fuel consumption (in miles per gallon). The L62 produced 140 hp (104 kW) @ 3800 rpm and 265 ft·lbf (359 N·m) @ 1400 rpm. Cadillac hailed the L62 as a technological masterpiece, and made it standard equipment across the whole Cadillac line.

This system was abandoned due to severe performance and maint issues, mostly due to ecu data rates and emissions issues.
