12 Rotor Engine Running- Different Angles
Watch the last part of the video where there is a glass of water on the
engine. The engine runs so smooth it does not even ripple the water.
Looking at the glass on the back, you are seeing the reflection of the Exhaust tubes bouncing on the flat
surface of the water. The water actually does not even have a ripple.
Mazda 767B Pure & Amazing Rotary Engine Sound at Spa Classic 2014
The truly amazing Mazda 767b! This car has a rotary engine resulting in one
of the most beautiful and pure racecar sounds you'll ever witness!
All of this was filmed at the Spa Classic during the Group C race. It was
an amazing event with some of the most amazing cars I have ever seen, this
767b was without a doubt one of them!
I am truly honoured to bring you this content as I think this car is known
for its legendary sound produced by a rotary engine.

Extreme Budget Engine Rebuild- Part 1
DIY Home mechanic rebuilding an engine on a budget. This part covers how to
know if you need a rebuild, guaranteed minimum expenses you will have,
teardown, and how to measure for wear on the bottom end to determine if
parts can be reused or if new part replacement, or machine shop work will
be required and what it will cost. Strategy is to develop a complete
budget needed for the rebuild before investing any money in the project at

Awesome V12 Monster diesel engine Awake and Alive startup
Awesome V12 Monster diesel engine Awake and Alive startup
The first V-type engine (a 2-cylinder vee twin) was built in 1889 by
Daimler, to a design by Wilhelm Maybach. By 1903 V8 engines were being
produced for motor boat racing by the Société Antoinette to designs by
Léon Levavasseur, building on experience gained with in-line four-cylinder
engines. In 1904, the Putney Motor Works completed a new V12 marine racing
engine -- the first V12 engine produced for any purpose. Known as the
'Craig-Dörwald' engine after Putney's founding partners, the engine
mounted pairs of L-head cylinders at a 90 degree included angle on an
aluminium crankcase, using the same cylinder pairs that powered the
company's standard 2-cylinder car. A single camshaft mounted in the central
vee operated the valves directly. As in many marine engines, the camshaft
could be slid longitudinally to engage a second set of cams, giving valve
timing that reversed the engine's rotation to achieve astern propulsion.
"Starting is by pumping a charge into each cylinder and switching on the
trembler coils. A sliding camshaft gave direct reversing. The camshaft has
fluted webs and main bearings in graduated thickness from the largest at
the flywheel end." Displacing 1,119.9 cuin (18,352 cc) (bore and stroke
of 4.875" x 5" (123.8 x 127 mm)), the engine weighed 950 pounds (430 kg)
and developed 150 bhp (110 kW). Little is known of the engine's
achievements in the 40-foot hull for which it was intended, while a scheme
to use the engine to power heavy freight vehicles never came to
fruition. One V12 Dörwald marine engine was found still running in a
Hong Kong junk in the late-1960s.
Two more V12s appeared in the 1909-10 motor boat racing season. The Lamb
Boat & Engine Company of Clinton, Iowa built a 1,558.6 cuin (25,541 cc
(5.25" x 6" (133.4 x 152.4 mm)) engine for the company's 32-foot Lamb IV.
It weighed in at 2,114 pounds (959 kg). No weight is known for the massive
3,463.6 cuin (56,758 cc) (7" x 7.5" (177.8 x 190.5 mm)) F-head engine built
by the Orleans Motor Company. Output is quoted as "nearly 400 bhp (300
By 1914, when Panhard built two 2,356.2 cuin (38,611 cc) (5" x 10" (127 x
254 mm)) engines with four-valve cylinder heads the V12 was well
established in motor boat racing.
In automobiles, V12 engines have not been common due to their complexity
and cost. They are used almost exclusively in expensive sports and luxury
cars because of their power, smoother operation and distinctive sound.

Engine Running NO OIL - NO SUMP - Seized Soild on Camera
Messing with a Mitsubishi Lancer
There are loads of videos where people run an engine at full rev with no
oil in it, and the engine seizes.
Running it a medium rev, I wanted to see how long it would run with no
lubrication, and I was surprised.
However if the car was driving and the engine was under load, it would be
dead in minutes!
What its like owning a 3 Rotor 20B RX-7
I have one of the most amazing custom RX-7s in the world. I want to share
my experience of owning and driving such a unique car.
I explain where the engine came from, why its so special, and what it does
to a Mazda RX-7

Handbuilt 4-Rotor Engine
This was a project that took about five years of weekends to put together.
There was a lot of trial and error as jury-rigged parts were improvised and
revised, leaks were identified and plugged, and byzantine electrical
diagrams were decoded. It still does not run smoothly, as there likely is
a problem with the intake system that has prevented smooth timing at idle.
But she runs!
lots of people wanted to know where the E-shaft came from: it was custom
ordered from a shop in New Zealand.
