WSK PZL-Kalisz

WSK PZL-Kalisz is a Polish aviation industry company in Kalisz that makes radial piston aircraft engines and engine parts. It has been part of the Polish aviation industry since 1952. It says it is the only producer of the ASz-62 IR piston engine.

The company works with major manufacturers around the world on aviation production. It points to its experienced workforce, a rich machinery fleet and controlled manufacturing processes that are backed by certificates.

Its main products and services are radial piston aircraft engines, including the ASz-62IR-16 and ASz-62IR-M18, and repair of the ASz-62IR engines it produces. It also makes assemblies, subassemblies and parts for aircraft engines, and a wide range of gears and gear shafts for aviation. For flow engines, it supplies thin-walled casings, compressor casings, gaskets, reducers and high-speed gearboxes. For compression-ignition engines, it makes crankshafts, connecting rods, pins, casings, impellers, diffusers for turbochargers, gear oil pumps, gearbox and pump casings, gears and camshaft parts. It also provides thermal and thermal-chemical treatment as an industrial service.

The ASz-62IR-16E is a nine-cylinder, air-cooled piston engine with about 1000 horsepower and an electronically controlled fuel injection system. It holds an EASA E.140 certificate. It grew out of the proven carburettor engine ASz-62IR-16 and uses an electronic control unit with many speed, pressure and temperature sensors. The company says this cuts fuel use by 20 percent and allows much cheaper car fuel. It also lowers harmful emissions. The engine can run on Avgas 100LL, aviation gasoline WA UL 91 or car gasoline E5.

The engine is designed for An-2 aircraft. The An-2 is built in agricultural, transport, passenger and floatplane versions and is flown in many countries. The company notes its simple build, reliability and strong resistance to field conditions.

WSK PZL-Kalisz does not currently repair engines of the AI-14R group. It gives these reasons: loss of production capacity for main engine parts, a lack of material suppliers for castings and forgings, and low interest from partners because demand for these engines is small. It does sell stored spare parts, and it lists spare parts and bulletins for the AI-14 and ASz-62 IR engines.

A subsidiary extends the offer. It produces specialised tooling, control and measuring equipment such as gauges, and tooling and gauge construction built to client needs. It also does machining and thermal treatment for single items and small batches.
