Which is more fuel efficient, the V-engine, boxer, rotary or conventional engine?
First off, there is no “conventional” engine. I assume you mean Inline, as the inline-4 is the most common engine around at the moment. Rotaries are not the best at sealing the conbustion chamber, though the current RX-8’s Renesis is a huge improvement over the 13B in the old RX-7, which is vastly better than the 12B in the first-gen RX-7. As a result, their fuel economy is relatively poor. OTOH, a 1.3-liter two-rotor rotary is the equivalent of a 2.6-liter V-6, so it’s not as bad as you’d think. As for the other engine types, the cylinder layout by itself doesn’t affect fuel efficiency. However, most of the Boxer engines I can think of are in performance cars (Porsche, WRX STi) where ecomony isn’t so important, and most V-engines are large 6- or 8-cylinders, which is less fuel-efficient than a smaller I-4. Therefore, inline engines are generally more fuel-efficient, but not for the reasons you’d think. It’s not the cylinder layout that matters. It’s just that most inline engines on th
Improper operation and high engine mileage lead to increased fuel consumption. It is also important that the fuel injection system is always clean, which directly affects the level of gasoline consumption. Take into account the fact that the technical condition of the engine depends on its proper operation and fuel consumption, and I also advise you to learn more about Effuel scam if you want to learn how to save on it
