Titanic was equipped with three main engines - two reciprocating four-cylinder triple-expansion steam engines and one low-pressure steam turbine engine, each driving a propeller. the two reciprocating engines produced a total of 30,000 bhp, while the turbine engine produced 16,000 bhp. White Star Line used the same engine combination on the early passenger ship Laurentique with great success. It offers the perfect combination of performance and speed; the reciprocating engine on its own is not powerful enough to propel an Olympic-class ship at the required speed, while the steam turbine engine, while powerful enough, causes uncomfortable vibrations for passengers, a problem encountered by Crown Tat's all-turbine passenger ships, the Lusitania and the Mauretania. By combining reciprocating engines with steam turbine engines, White Star Line was able to reduce fuel usage and increase power while creating the same amount of steam.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eFeatures:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003e.Authorized and designed by borysf, this model is designed base from the 1\/22 scale reciprocating triple expansion steam engine of a classic ship - Titanic.

The Titanic was fitted with power generation equipment that produced more electricity in the same amount of time than the average urban power plant of the time.

This hit and miss engine adopts carefully selected high-quality materials and exquisite craftsmanship to assure the engine's reliability and durability. The design features a transparent, adjustable flow main oil cup, a new carburettor and a reverberating exhaust pipe. The two large flywheels are well weighted, with a spring loaded ball and split wide face pulley, making the engine very practical for power output. A special design with a rarely seen \"fast and slow gear change\" allows the engine to be switched between super slow speed and high speed for power output. This makes the engine more playable and the player more operational. Product technology: the whole machine Ferrari red paint using electrophoresis surface treatment process, the main components (body main body, flywheel, connecting rod, etc.) are made of stainless steel 304 casting, all assembly surface using CNC finishing, high carbon steel hardened one-piece crankshaft.

Based on the suggestions of numerous antique engine model collectors, restorers, and builders, and in our unique way of paying tribute to the classic industrial machinery of 100 years ago, we have launched this miniature scale model engine. Its history began with the sale of the first engine in 1926 and continued until production ceased in 1964, with over 250,000 units produced during that time. This groundbreaking research covers significant changes and improvements to this scaled-down engine, encompassing areas such as the fuel tank, mechanical ignition system, flywheel, and exhaust system, and features the first use of a 16mm bore metal piston ring. Interestingly, many stationary engine enthusiasts worldwide began their collections with this very engine – including ourselves – and this seemingly ordinary single-cylinder engine is indeed extraordinary! The restoration and maintenance of these engines bring endless joy to enthusiasts of all ages. Many young people learn the principles of internal combustion engines through hands-on experience, often using this engine as a stepping stone to larger and more professional mechanical fields. To the untrained eye, all such engines may seem similar, but in reality, they are vastly different – something every enthusiast knows well.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Features:\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e1.\u003c\/strong\u003e A Century of Tribute - Classic Stationary Engine: This engine was the \"entry point\" for countless stationary engine enthusiasts.
