What does MRE mean in PRODUCTS

The McMaster Rotary Engine (MRE) is a type of internal combustion engine that converts energy from fuel into kinetic energy. Unlike traditional engines, it uses a rotary motion, meaning the pistons spin rather than slide up and down the cylinder. This gives MREs more efficient output as well as better fuel economy.

An MRE takes air in through the intake valve, compresses it in the combustion chamber and then ignites it with a spark plug. As the pressure builds from the combination of heat and pressure, it causes the rotor to spin rapidly and power is generated by harnessing this rotational energy.

MREs have higher torque at lower speeds due to their design which increases engine power output for less fuel input. They also reduce emissions due to their higher efficiency, making them much cleaner burning than other types of engines. Furthermore, they are lightweight and can be built in any size or shape for different applications.

Some drawbacks of using an MRE include difficulty in controlling idle speed, increased vibration at low speeds due to high friction between moving components, increased production costs due to intricate assembly required and higher maintenance costs since each part needs frequent lubrication.

The size of an MRE can vary depending on its application; however typical sizes range from 0.5 liters up to 4 liters of displacement per rotor chamber including single rotor designs or multi-rotor configurations with up to four rows per engine block.

Depending on usage conditions like temperature variations, lubricants used etc., but typically they have a service life of 100k-200k miles (160k – 320k km). With regular maintenance including oil changes being performed every 5k-7k miles (8km - 11km), an MRE can last much longer than that if properly taken care of over time.

It’s best practice to use manufacturer approved lubricants specifically made for rotary engines with anti-wear additives that will protect against excessive wear and tear during operation since these require more frequent oil changes due to their high temperatures in operation.
