TECHING Updated L4 Engine Model Kit that Works - Build Your Own Engine - Full Metal 4 Cylinder Car Engine Kit Car Engine Model
1.Origin of the story:

The birth of the inline four-cylinder engine: In 1894, Maybach and Daimler completed the research and development design of the inline four-cylinder engine. The cylinder blocks were all cast, and the carburetor patent technology that Maybach had just obtained in 1893 was used.
Excellent engine of the 19th century: This inline four-cylinder engine from Maybach was indispensable in almost all excellent cars in the world at the end of the 19th century. This achievement was accomplished shortly after Maybach and Daimler were squeezed out of the company and started anew.
Application of the original L4 engine: In 1913, Jules Goux won the Indianapolis 500 in a Peugeot. The engine of this racing car is an inline four-cylinder engine designed by Ernest Henry. This design featured the first use of dual overhead cams and four valves per cylinder, making it deeply influential as an engine for racing applications. It remains the structural standard for inline four-cylinder engines used in racing cars to this day.
