Post Engine question!!

does anyone know what engine can be made to be the most effeceint engine. Since most engines are only 7% effeinct anyone know an engine or engine combo that would be a lot better. Would it be a Hemi and SBC or a ford, or one of the inline engine's ??

One of the Honda or other foriegn multi-chamber designs with electronic fuel injection is as good as you are going to get with a production car. If you want power, any new electronic fule injection car is not too bad. My wife drives an Expedition with the big V-8 and gets 25 mpg on the hi-way.

Like 4-Jaw says, you will need to get into combined cycle (one engine process using the rejectd heat from another process) and/or regenerative processes (elecrtic motors that generate electricity ans they help break the car). Unfortunately, you wouldn't be happy with the price or performance of these options.

I find that putting black electrical tape over the gas gauge makes a car more effieciant.

a big block stroked to 496ci, merlin heads, tunnel ram with two holleys on top and a BIG LUMPY CAM. hehe NOT. although their is a dfference in gas mileage and effeceincy. i think the most effeceint motors nowadays are the turbo charged rotary egines by mazda. but i could be wrong. horsepower usually comes from effecency. if a sbc is gonna be used at 2000rpm then selecting the right parts and tuning for that rpm(with efi) can net a nice effecient engine. but thats about as good as it gets unless you feel like ditching pistons for a rotory motor.

It takes 20 liters of fuel to go 1 mile? You probably have to fill up after leaving the driveway. lol. I'm just joking, but what would this be in miles per gallon?

I believe the hyper injection pressure diesel engines are doing about the best right now, AFA IC goes. 'Course this could have changed (if it was EVER correct) since I was last aware.

The most efficient engine that I have ever seen is a tricycle motor. Feed it some fruit loops with a little bit of sugar on top, with some vitamin D added whole milk and it will run all day long.
