Rolls-Royce bouwde ooit een wankelmotor op diesel
Ho shit, technique on Sunday.

All grasduinend by the various shall present you one of these days were presented, it became clear: it is time for some floor. Well, that floor you can get. Rolls-Royce has ever been a serious attempt to create diesel and wankeltechniek (detailed explanation) with each other to combine, so as to create a compact engine for tanks to build that nevertheless have enough power generated to tonnes of steel and ammunition from their place to get.

The obstacles that the British it had to overcome are evident, but the solution is simply a genius. For diesel engines you have a high compression is required, so that the air is hot enough (and the pressure is high enough), after injection of the diesel fuel spontaneously ignite. Various attempts to obviate this difficulty, were not working to the full satisfaction of the engineers. Therefore, used Rolls-Royce a compressor, but in the form of… An extra disc!

On the picture above you see two disks that are placed below each other. Contrary to what you might expect is the upper disk, the instance that is the output it generates. The bottom disk is intended to the air through the inlet port, the engine being sucked in to compress, and through a narrow channel to move to the drive where the combustion takes place. The latter disk is much smaller and compresses the air even once, after which the diesel is injected. Then ignites the mixture and the force is transmitted to the crankshaft.

For the cijferfetisjisten: the upper combustion chamber had a capacity of 1.265 cc, the lower (purely so it was used as a compressor) a content of 3,250 cc. For comparison: the well-known Mazda RX-8 has two combustion chambers, each with a capacity of only 654 cc. The ability of the relatively compact Rolls-Royce motor came in at a solid 350 hp @ 4.500 rpm, but keep in mind that this diesel engine already in 1972, was built. Also weighed the block is about 450 kg, where a conventional diesel engine with comparable output approximately double weighed.

Unfortunately threw finance spanner in the works and so was the development of the Rolls-Royce R6 discontinued for the principle and the practice was tested. Sin, but impressive technique is definitely.
