A Quick Explanation of the Rotary Combustion Cycle

1. Intake

Intake

The fuel mixture is drawn in by the vacuum created as the chamber increases in volume with the clockwise rotation of the rotor. Compression

2. Compression

Compression

The fuel mixture is compressed as the chamber drastically reduces in volume with the further rotation of the rotor.

3. Ignition

Ignition

At the ideal time (varies depending on application) the spark plugs energise, igniting the fuel mixture. The burning mixture rapidly increases in pressure and pushes on the rotor, forcing it to continue its rotation. It is in this phase of the cycle that power is delivered to the central crank or eccentric shaft.

4. Exhaust

Exhaust

With the continued rotation of the rotor, the spent mixture is then allowed to expand as it is pushed from the chamber into the exhaust system.

The whole time this cycle is in sequence, two more identical cycles are also operating on the other faces of the rotor. In most cases, this is then complimented by a second rotor alongside, operating exactly 180 degrees out of phase (upside down) to the first. This produces a smooth power delivery with the six pulses of energy following behind each other in perfect unison, not unlike the smoothness found in an electric motor.

MAZDA's Rotary Engine

Many different designs for rotary mechanisms have been attempted over the last 400 years, but what makes the NSU-Wankel engine, which Mazda adopted, stand out is its "rice ball-shaped" (triangular) rotor housing. Because of this design, three separate chambers are created between the rotor and the inner wall of the rotor housing. These chambers smoothly expand and contract in a constant cycle as the rotor spins. See the rotary engine in motion on the right.

The Rotary Engine of Mazda continues to evolve farther into the future. The new generation Rotary Engine "RENESIS" makes it superbly environmentally friendly with zero CO2 and almost zero NOx emissions. Mazda began commercial leasing in 2006, and currently many organizations and government bodies are enjoying the RX-8 Hydrogen RE.

MAZDA emblem

1962-1975

Symbol and corporate mark as seen on most Mazda cars from the Mazda R360 until 1975

1991-1992

In 1991, Mazda adopted a corporate symbol which was to represent a sun and a flame standing for heartfelt passion

1992-1997

Shortly after the release of the new symbol, the design was smoothed out to reduce its similarity to Renault's

1997-Present

A redesigned symbol was introduced in June 1997; it is a stylized "M" meant to show Mazda stretching its wings for the future

History Of MAZDA

Mazda began as the Toyo Cork Kogyo Co., Ltd, founded in Japan in 1920. Toyo Kogyo moved from manufacturing machine tools to vehicles, with the introduction of the Mazda-Goin 1931, although they produced weapons for the Japanese military throughout the Second World War. The company formally adopted the Mazda name in 1984, though every automobile sold from the beginning bore that name. The first four-wheel car, the Mazda R360was introduced in 1960, followed by the Mazda Carol in 1962.

The Ford Motor Company has owned 25% of Mazda since 1979, and its stake was increased to a 33.4% controlling interest in 1996 when Mazda fell into financial crisis. Ford has based many of its models on Mazdas, such as the Probe, late model (North American)Escort and Mercury Tracer, and the co-developed Mercury Mariner/Mazda Tribute.

The 1979 deal paved way for Ford selling badge-engineered Mazdas in Asia and Australia, such as the Laser and Telstar. These models replaced the models from Ford Europe sold throughout the 1970s. Ford also used the Mazda models to establish its own retail presence in Japan - the Autorama dealers sold these cars, plus the occasional Ford US and Ford Europe models.

The badge-engineered models came to an end in the early 21st century, as Ford replaced the Laser with its own Focus, and Telstar with its own Mondeo. Ford and Mazda have moved onto collaboration in a more fundamental sense, by way of platform sharing.
