Company Profile

Rima Industrial SA was founded in 1952 and is currently a worldwide leader in the production of Silicon Metal and Ferro-alloys and the sole Magnesium Metal producer in the Southern Hemisphere. The Rima Group operates 3 industrial plants in Brazil that are fully integrated with forestry and mining units. The group has more than 4000 employees.

Rima is located in the state of Minas Gerais, the third largest exporter in Brazil. Rima utilizes the best available technology together with highly qualified personnel to meet the expectations of our customers while following strict safety guidelines and respecting the environment. The company exports its products to worldwide markets, including Europe, Asia and North America and assures the quality of its products under international ISO Certification such as ISO 9001:2008, ISO TS16949:2009, ISO 14000:2004 and OHSAS 18001.

Rima’s process is fully vertical and green. Magnesium and aluminum die cast parts for the automotive and aeronautic industries are manufactured from the company’s own mining resources using fully renewable raw materials throughout the process that reduces greenhouse gas production.

In 1981, Rima became the exclusive supplier of primary magnesium alloys to Volkswagen Brazil. In 1999, Rima acquired Volkswagen’s Brazilian die casting plant and improved their Magnesium Die Casting technology and products. As a result VW was able to extend the warranty period of their components due to the high quality products supplied by Rima.

As a reference it is important to mention that the quality evolution experienced by the famous air-cooled engine block produced by Rima and commercialized worldwide using the VW brand. This engine block was originally developed by the Hungarian engineer Josef Ganz in the 1920s, initially for motorized German gliders but later used by Ferdinand Porsche for the VW Beetle. Volkswagen never had any interest in developing an aeronautical platform using the Beetle engine.

For many years several companies contacted Rima asking about the possibility of developing a new aircraft engine, once it had acquired VW’s die casting foundry.
In 2006 Rima decided to start a green field project by converting the VW Beetle basic design to a new air-cooled aircraft engine and in 2009 the first prototypes of the new engine were produced and operated in Rima test facility. A great deal of experience was gained with these engines that aided in further development.

In 2012, Rima’s aeronautical engine project was acquired by MOTORAV Industria e Comercio LTDA, which maintained operations in the town of Bocaiuva, Minas Gerais – Brazil, where the engine was originally developed.

Experimental aircraft builders and designers were consulted for their input. Other converted VW engines were analyzed for their strengths and weaknesses, and in 2014, MOTORAV hired as a consultant Mr. Bill Brogdon of bmep, Inc. He has over 40 years’ experience in the design of piston engines and is a former Chief Engineer of Continental Motors.

MOTORAV engineers, designers, analysts, manufacturing engineers, managers and consultants worked together to design the engine specifically for the experimental aircraft engine market.

This design work resulted in significant improvements such as: a reinforced engine crankcase, one piece integral flange crankshaft, exclusive cylinder heads, intake and exhaust on the underside of the cylinder head, easily accessible dual spark plugs per cylinder, standard bayonet cylinder head temperature thermocouples, electronic ignition, integral alternator, removable hydraulic lifters (no more valve adjustments), high performance camshaft, remote or improved integral oil cooler, extra capacity oil sump, and features to make the engine easier to install and adaptable to the majority of the existing LSA aircrafts.

A range of sophisticated analysis techniques were utilized to improve the engine design and performance. FEA (finite element analysis) studies were performed on the design, by top worldwide experts in the aircraft and engine industry such as ITA (Aeronautical Technological Institute in Brazil), and Integral Powertrain Ltd. in England.

Other analyses included: Engine performance and optimization of manifolds and valve timing, valve gear dynamic analysis, crankshaft stress analysis, torsional vibration analysis and mold flow analysis. The results of these analyses were used to improve the design of the engine. MOTORAV LTDA, has accumulated extensive background on the engine operation using its own bench tests and aircraft.

The start of sales of the new MOTORAV engine is forecast to be in the second half of 2017.

MOTORAV has an exclusivity agreement with Polymet Alloys Inc., for the sales and service parts distribution in the North American Market.
The markets in the rest of the world will be supported by MOTORAV LTDA directly from Brazil, including sales and service parts distribution.
