Builder of the World's Smallest Internal Combustion Engines by George Luhrs

George Luhrs miniature single-cylinder engine

This engine's full name is Luhrs engine, which is a contraction of that name.

The well-known George Luhrs created and invented this model engine in 2001. For most of his life, George Luhrs built engines of all sizes. He constructed a wide range of models as a child, such as model boats, model vehicles, and free flight and "U-control" aeroplanes. As a teenager, George also started working on cars and fixed and rebuilt minor engines. He acquired the skills necessary to handle a variety of tools, including machine shop equipment required to construct and fix pieces, in order to achieve his goals. A New York Times piece also highlighted Craftsman of the Year Pierre Scerri and George Luhrs.

However, George died in 2014, and several of his engine models are no longer available. We have recreated this Luhrs engine in his honour and to carry on his legacy. It has a slight cooling fan inside, a fan shroud on the right side of the cam casing, and an overhead valve structure with spark plug ignition. External mechanical ignition (no Hall sensor), forced air cooling, and a separate crankshaft lubrication box made primarily of aluminium alloy are also present.

The size and stroke of this single-cylinder, spark-plug gas engine are 1/8" and 5/32". Only 0019 cubic inches are displaced. In 1996, George created this small engine from the ground up. When it runs, he observed, it buzzes like a bee. For scale reference, a portion of a US penny is seen at the bottom of the image. Thomas Oversluizen provided the image.

George's assertion that this is the slightest operating spark plug-fired gas engine ever constructed was uncontested at the time of writing. Thomas Oversluizen provided the image.

Many model engine aficionados have been impressed by the two single-cylinder engines that the V8engineforsale team and MUSA manufacture have released in recent years as homages to the classics "Whippet" and "Red Dog."

We will honour George Luhrs, a master artisan, once more in September 2023. Once more, we celebrate the great craftsman George Luhrs, who devoted most of his life to creating model engines of all sizes until passing suddenly tragically in 2014. To honour him and preserve his memory, we present the George Luhrs Engine, which is based on his creations. We are offering you a re-built miniature single-cylinder four-stroke engine that is based on the George Luhrs Engine in remembrance of this outstanding artisan and to preserve his memory.

The CNC-machined engine parts include a hardened crankshaft and shims. The engine has an overhead valve construction, a compact, transparent fuel tank, an external mechanical ignition system with an adjustable ignition advance angle, and a centrifugal fan for forced air cooling.

Homage to classic: This engine will evoke a greater sense of nostalgia and resonance among gamers and engine modellers, which is remarkable and garners a lot of interest and conversation.

Exquisite appearance: With its compact little structure and overall silver colour scheme, this tiny vertical single-cylinder four-stroke engine has a unique and lovely appearance. You will enjoy how well it works.

Ingenious design: The engine has an external mechanical ignition trigger with an adjustable ignition advance angle, an overhead valve structure, and a fan cover with a slight cooling fan inside the proper cam housing.

Excellent quality: The crankshaft, toughened with axle shingles, was completely CNC machined and fabricated. The surface was anodized and sandblasted to display the engine's mechanical texture and beauty.

EXCELLENT COLLECTION: This decorative engine is ideal for collectors and engine model aficionados. It is also one of the most essential engine types at model exhibits and makes a wonderful personalized present for those who enjoy mechanical things.
