yes and no. The amount of gas you saved would be only nominal because the engine was not designed to do this, but theoretically it is possible.
It would be underpowered and a traffic obstacle to everyone else ~~
it puts more strain on the remaining cylinders and will actually reduce the mileage, to increase your mileage start of slowly and brake early and easily
i don’t think you can do that on an engine that wasn’t desgin to do so and even if you want to deactivated you would have to do it to an entire bank meaning 3 cylinders. The ONLY v6 that does that is Honda’s V6 with VCM (Variable Cylinder Management) and that engine is complicated if you see the cut away (well all honda engine are high tech and complicated anyway…Deactivation of cylinders is achieved by releasing a synchroniser pin that normally interlocks the cam follower and rocker arms. The synchroniser pin is released using hydraulic pressure which is controlled by a dedicated solenoid. Once the synchroniser pin is released, the cam follower continues to move against the camshaft but the rocker arms and valves remain in a closed position.
So no i don’t think so.
Paul H….Honda have V6 with deactivation of 3 Cylinder in the Honda Pilot and Odyssey. But only because these are v-tec high output V6 (300HP from 3.7L naturally Aspirated)
This would save little (if any) gas, and make the car a total dog - perhaps dangerously so.
Better to sell it and buy something more economical.
Chrysler experimented with cylinder deactivation back in the 70’s with valve train solenoids to shut down certain cylinders of a V-8 at highway speeds which require far less power to maintain than under acceleration (some estimates put it at around 40-50 horsepower) but the technology was pretty expensive and complicated back then. Cadillac later came out with a system known as the 8-6-4 which was an improvement but still had issues. Other companies are taking another look at it with newer technology available. A person could employ a deactivation of fuel to certain cylinders to improve mileage but you would have to figure out which cylinders to shut down to keep power balance and firing order fairly smooth….not an amateur process and may not be possible with a V-6 configuration.
Your best bet is to reduce speeds to around 55 mph to get the most efficiency…anything over 45 mph requires exponentially more power to maintain and thus less fuel economy. Try to use the cruise control as much as possible, keep tires properly inflated and remove any excess weight from the car.
It would not save you any gas,
Having two cylinders not functioning on a v-6 engine will reduce engine performance and cause your fuel mileage to decrease.
If you want better mileage… make sure you have a complete tune-up, and that your tires are inflated to the proper pressure. Having your engine running at the optimum efficiency is the best way to get the maximum gas mileage.
This is not possible on your Maxima. Try driving with a lighter foot, have your tires inflated to about 33psi, and keep the speed limit. It’s cooler now so no need for Auto on your aircond — that puts a bit of drag on your engine. Use regular gas, not any biofuels. Your book says to use premium for best performance. but the same book says the engine computer adjusts your engine for regular. Mine (97) never sees premium. Unload any heavy content from your trunk. Hey, we’re getting to about 27mpg here and with that car, that’s about as good as it gets.
Please just drive slower with less throttle. Better tires proper pressures. Car pool and buy a newer car because they make less greenhouse gasses and get better milage. Unplugging two injectors is about the worse thing you can do those cyls have to be powered to stay warm and lubricate properly.
sure, pull two fuel injectors, that will make it run real nice
You can disable two cylinder by disconnect two injectors but It will increase gas consumption. (not save).
The two disable cylinder will work as an air pump. Oxygen sensors in the exhaust will report lean condition to engine computer. The 1996 engine computer is not smart so it will inject more fuel.
The result is: waste gas, damage cylinder walls, lack of power, damage catalytic converter (it may burn your car if it gets hot enough), extremely high pollution output, backache (for working harder to pay for all the repair and gas)
