History

Founded in 1947, the company was originally known as Associated Engineering Holding Ltd. In 1968 the company became AE Autoparts Ltd. based in Bradford, England. From 1973 to 1982 AE® expanded its product portfolio to include valve-train and cam-train, and even received the Queen’s Award for Export Achievement in 1978. The AE valves product range offers a comprehensive coverage of the European vehicle parc.

Top Engine products

The quality and precision of components associated with the cylinder head – known as ‘top-engine’ – are vital to ensure effective management of fuel, air and combustion. Turbocharging, engine downsizing, stop/start systems and other techniques for CO2 reduction are driving up temperatures and pressures while rising biofuel contents contribute to an even more aggressive top-engine environment. Only components that employ OE design expertise, with the latest combinations of advanced materials and very high manufacturing quality, can provide the performance and durability that professional engine technicians demand.

Engine valves

Engine valves are precision components design to seal inlet & exhaust ports of an engine. They are one of the most stressed parts enduring very high temperatures, responding to rapid movements, forming an effective seal and being reliable for thousands of hours of service.

Manufactured to high standards, AE valves ensure maximum performance and durability. By engineering our valves in-house, AE fully controls the product process, from drawing to quality control. This enables us to offer you premium quality at a very competitive market price.

Quick look benefits - Valves

By using high quality AE® valves, repairers can effectively fulfill these requirements and achieve as good as new specification engine rebuild, AE® offers the following

Special alloy steels, austenitic/martensitic steels
Bi-metallic, mono-metallic and sodium filled, dependent on requirements of the application
Surface coating - chrome, triple chrome and nitride
Hardened (stellite) seats and tip
Pre-finished seat - eliminates the need for lapping-in
All AE® valves are tested for roundness and concentricity
Every single AE® valve is laser marked with an AE® part number for easy identification

Feature highlights 1

Mono-metallic valves are manufactured from a single piece of metal. The main material selection criteria are high resistance to heat and good sliding properties. Bi-metallic valves are manufactured from two different materials to achieve the best combination for stem and head, used mainly in exhaust valve application. Head material chosen for high temperature strength, hot corrosion resistance and stem material chosen for high hardness giving better resistance to wear.

Feature highlights 2

Sodium-Filled hollow valves

To reduce temperature, 60% of the valve cavity is filled with metallic sodium which melts at approximately 97°C and during valve operating condition, the liquid sodium moves up and down the valve cavity transferring heat away from the valve head to the valve stem, thus increasing heat dissipation via the valve guide. Hollow valves are lighter in weight due to the design, weight reduction between 6% and 16% is possible, depending on the type of hollow valve.

Temperature reduction in the valve underhead region between 80°C to 150°C
Heat dissipation reduced from the seat and transferred through to the guide by 20%
Weight reduction by up to 16%

Engine valve guides and seats

AE® valve guides and seats are produced from a wide range of high-quality materials, including various bronze and cast iron materials for guides and nickel based premium materials for seats, offering one of the most comprehensive application coverage.

Valve guides play a vital role in the engine by absorbing 25% of the total engine-generated heat. AE® guides are produced from material which offer excellent wear resistance and good thermal conductivity.

Valve seats absorb 75% of the total heat generated by the valve heat and thus AE® seats are produced from high quality materials including nickel-based alloys.

Quick look benefit - Valve Guides

AE® valve guides are fully finished, ready to fit into the cylinder head without any further machining, however in all cases the valve guide bore should be measured after fitting to ensure the correct valve stem to valve guide clearance.

Camtrain

Produced for superior engine performance and smooth, quiet operation, AE camtrain products ensure correct timing, long-wearing surface skills and increased valve lift and duration capability. Choose AE and get the assurance of camtrain components that live up to the highest standards.

Quick look benefit - Camshaft

AE®’s camshafts are produced from carefully selected materials including alloy steel, carbon steel, low-carbon steel, grey cast iron and chilled cast iron.
