Aircraft engines

A nine-cylinder piston air-cooled engine of 1000 KM power with electronically controlled fuel injection system has EASA E.140 certificate issued by European Aviation Safety Agency.

Drive mechanism developed on the basis of a tested construction of carburettor engine ASz-62IR-16 uses newly developed electronical control system ECU, controlling the proper unit work with the use of numerous speed monitors, pressure and temperature of different systems. By means of feedback information collected from sensors, the control unit monitors the BOSCH fuel injectors’ work to optimise the quantity of proper fuel-air mixture in a cylinder.

Such solution allows for reducing the use of fuel of 20% and makes it possible to use considerably cheaper car fuel. Significant reduction of harmful fumes compounds emission has positive influence on environment.

The engine is designed for An-2 airframes, produced in different versions – agricultural, transport, transport and landing, passenger, water on floats and  is exploited in many countries all over the world. An-2 is characterised by simplicity and construction reliability, as well as exceptional resistance to exploitation in field conditions.

Please note

Company WSK ‘PZL-KALISZ’ S.A. currently does not perform repairs of engines from AI-14R group due to:

  • Loss of production capacity of main engine elements and subassemblies,
  • Lack of material suppliers (castings, forgings, etc.) necessary to engine production,
  • Lack of engine parts suppliers,
  • Lack of interest on the part of contractors to resume or start cooperation due to low volume of demand for engines.

At the same time, we offer sale of stored spare parts. Full list of spare parts can be found in a tab ‘after-sale service’ / ‘list of parts’.
