The Napier Sabre H-24 Cylinder Aero Engine

Napier Sabre Aero Engine

In these very interesting videos from Flight Dojo YouTube channel a salute is given to the astounding performance of the wartime power plant of the Hawker Typhoon and Tempest fighter aircraft.

An extremely potent blend of compact racing engine design and wartime necessity made this innovative and original design of 24 cylinder in 2 flat horizontally opposed 12-cylinder banks something of an ultimate petrol-powered aero engine.

There are relatively few common horizontally opposed internal combustion engines in use now, the Porsche 911 car and some MTU or Tedom diesel-hydraulic train power packs being an exception to the rule, these just don’t come close to the Sabre however!

As you watch these videos it becomes clear the incredible power-to-weight ratio that was achieved with often indifferent interest from the air ministry and of course the 25hp Coffman explosive starter must have been impressive as well!

One can only speculate on engine oil challenges faced by mega-powerful high output petrol piston engines and the violent movements that aerial combat must have involved. 

Euro 5, 6, And 7 Emissions

With the ongoing debate and concern over NOx and other emissions from automotive, industrial, power generation and marine diesel engines the global regulations on emissions are a moving scene that affects fuel refineries and suppliers, engine manufacturers, lubricant blenders and catalyst manufacturers.

Lubrication Explained is a no-nonsense YouTube channel by an Australian engineer – we have shown a video here that we found very helpful.

Have you ever wondered what the firing sequence and actual appearance and dramas inside an internal combustion engine look like?

Destin at Smarter Every Day also had always wondered and – having access to a very high speed camera – visited some engineers in the north west USA to see a Briggs & Stratton petrol engine that has a transperant cylinder head!

This means all four strokes of the fuel, spark, compression, power, and exhaust strokes can actually be photographed on video – quite incredible! Please see this below:
