The 13B rotary engine is a type of internal combustion engine that has significantly improved the performance of sports cars, especially the Mazda RX-7. It is known for its unique design and high-revving nature. In this article, we’re going to discuss the 13B rotary engine diagram, its components, and how it works. We’ll also answer some frequently asked questions about this engine.
13B Rotary Engine Diagram: Components and How It Works
The 13B rotary engine consists of three major components: the rotor, the housing, and the eccentric shaft. The rotor is a triangular-shaped spinning part that generates power by turning the eccentric shaft. The housing has two chambers, where the rotor moves back and forth, creating a combustion chamber.
The engine works in four stages:
The Intake Stage
The rotor moves toward the combustion chamber, creating a vacuum that pulls air and fuel into the chamber. The fuel is atomized as it enters, creating a fine mist for combustion.
The Compression Stage
The rotor moves upward, compressing the fuel-air mixture, making it highly volatile and ready for combustion. This stage is crucial as it determines the power output of the engine.
The Combustion Stage
The spark plug ignites the compressed fuel-air mixture, generating power that drives the rotor down. This power is transferred from the rotor to the eccentric shaft, which then rotates the crankshaft, producing power that drives the wheels.
The Exhaust Stage
The rotor moves toward the exhaust port, pushing out the exhaust gases that are generated during the combustion process. This completes one full cycle of the engine, which then repeats itself for continuous power generation.
The Eccentric Shaft
The eccentric shaft is the link between the rotor and the crankshaft. It is responsible for converting the rotational motion of the rotor into the reciprocating motion of the crankshaft, which produces power that drives the wheels.
13B Rotary Engine Diagram: Components of the Rotor
The rotor of the 13B rotary engine has two major components: the apex seal and the side seal. The apex seal is responsible for sealing the combustion chamber, ensuring that the compressed fuel-air mixture doesn’t escape. The side seal is responsible for sealing the rotor housing, preventing oil and other fluids from escaping the engine.
The rotor also has two grooves, where the apex and side seals are placed. These grooves are cut at a specific angle, ensuring that the seals fit perfectly and seal the engine tightly.
13B Rotary Engine Diagram: Frequently Asked Questions
What is the horsepower rating of the 13B rotary engine?
