Rolls-Royce Engine Cylinder Blocks

A passion for Rolls-Royce cars and an ambition to perfect the design of cylinder blocks are the twin engines of Kent-based Ameeco Engineering.

The company uses C106 copper tubing as part of its Rolls-Royce 20 hp cylinder blocks that are currently supplied worldwide.

New Engine Cylinder Blocks for Rolls-Royce 20 hp Cars

The Rolls-Royce Twenty was built between 1922 and 1929. This car, designed by Sir Henry Royce, came into the market as a small car successor to the Silver Ghost. Ameeco Engineering produces new engine cylinder blocks for this historic car.

The blocks in the day were made of cast iron. Ours are too but the thin-walled construction is particularly difficult to make, leading to a documented failure rate of 80% when produced. Of the 20% good ones produced, many are suffering from normal age-related problems coupled with damage throughout the last nearly 100 years.

This high failure rate meant an opportunity for improvement for Derek, who has experience in oil exploration, electrical engineering, and sonar defense. Derek, one of the founding directors of Ameeco Engineering, was determined to enhance the design while remaining faithful to the appearance of the original engine blocks.

We have redesigned the blocks to look outwardly identical to the originals but manufactured in a different way. This has led to a 100% success rate of manufacture. Being cast iron and with crankcase studs going through the cylinder block and cylinder head, the studs needed to be isolated from the water channels, this being achieved by inserting copper tubes securely fixed into tapered holes. These tubes were made of copper 100 years ago and we decided to maintain that design.

Ameeco Engineering collaborated with Columbia Metals to realize its design objectives.

Ameeco Engineering’s thorough knowledge of small horsepower Rolls-Royce engines and engineering ability have ensured that these changes in design are now integrated into all new blocks made for Rolls-Royce 20 hp cars.

We required 7/16” o/d C106 half hard tubing to meet the original specification. It was a natural choice to purchase the copper tubing from Columbia Metals as they have previously supplied nickel plate to us to make bonnet hinges for Rolls-Royce Silver Ghosts. The tubes have always worked successfully despite being totally immersed in water and with constantly changing temperatures of between 0 °C and 100 °C. They have never been known to fail or be the cause of water seepage. In my opinion, led by Sir Henry Royce’s high standards, Rolls-Royce produced the best car in the world which has led to their name being attributed to anything made to the highest standard and quality.
