Why did Mazda stop making rotary engines?

Why did Mazda stop making rotary engines?

Mazda last built a production street car powered by a rotary engine in 2012, the RX-8, but had to abandon it largely to poor fuel efficiency and emissions.

Do rotary engines have more power?

The Rotary Engine is very simple. It’s a motor design that utilizes way less moving parts than it’s piston counterpart. The 13B-MSP Renesis (from the RX8) has the highest horsepower per displacement of any naturally aspirated motor produced from the Factory in America. For it’s size, the rotary packs a punch.

Why do rotary engines use so much fuel?

The thing is; the rotary engines end up producing excessive power. The engines, in turn, are not built to handle the excessive power. As a matter of fact, the more power the more fuel is burnt as the revs of the vehicle get higher. This is the simplest reasons that explain why rotary engines offer a bad mileage.

Are there any cars with rotary engines?

No one would argue that Mazda’s RX-7 and RX-8 were the most famous roqad-going cars built with rotary engines. There was also the stunningly gorgeous Mazda 787B, which is the only rotary-powered car ever to win Le Mans.

Do rotary engines use spark plugs?

Rotary engines use two spark plugs per rotor, a leading and a trailing spark plug. The leading plug (mounted lower in the rotor housing housing) ignites up to 95% of the air/fuel mixture providing most of the power.

Why can rotary engines rev so high?

The secret to the high revving nature of rotary engines lies in the fact that all of the moving parts are rotational rather than reciprocating. Stress and valve float become an issue when reciprocating masses are high, such as in pushrod engines with valves and pushrods constantly changing direction.
