Specifications Napier 30HP OW 1902 blueprint

The Napier 30HP OW 1902 is an impressive feat of engineering. It is a four-cylinder inline engine from an era which developed the motor-car industry's first automotive machines. Constructed from steel and cast iron, this engine is literally a blast from the past. The overall design is somewhat rudimentary compared to later iterations of the motor. Its four cylinders measure at 4 inches in diameter with a 5-inch stroke, and sports a total of thirty horsepower with a four-speed overhead valve system. Cooling is provided by an external radiator with several exhaust ports, a feature which set the Napier 30HP OW 1902 apart from its competitors. The exhaust pipes are quite short and close to the engine, with a unique design that gives the 30HP a captivating look. Attached to the cylinder blocks are two flywheels, giving this engine an interesting vibe no other car has. A crank handle on the block helps start up the engine, while an accompanying light makes driving in the dark easier, even in 1902. Additionally, the 30HP's clutch is more advanced than most of its contemporaries, allowing smoother operation on the road. The Napier 30HP OW 1902 features several features throughout its construction that speaks to its quality and power. From its four-cylinder design to its short exhausts, this engine is a relic of a rapidly developing industry, allowing it to be admired for over a century.
