That Lanz Buldog with it's Hot Bulb was incredible! Next to it the beautiful Square four - that was a fabled engine even when I was a kid. Aerial made some really advanced bikes and engines: water cooled, Shaft drive, belt driven all way ahead of the time. But for me the Lanz for the win.

[@phillipcleaver7063]

A clever guy in America has recreated an efficient 2 - stroke high - revving diesel engine that uses minimal parts , I think it has 3 vertical cylinders , 2 opposed pistons in each , supercharged , crankshafts top & bottom linked up by a heavy roller chain , I left him a message by e - mail to try to get a look at a Commer "Knocker" engine , as he , I believe , has modernised & re - created it . I knew a guy who drove one of these daily , in a car transporter , they always have their own note , you knew he was home 1/2 a mile away ! . The commer one used to wear out quickly , due to the complex oscillating linkages between the con - rods & the one central underslung crankshaft , these engines always sound as if they are screaming when you rev them , actually they aren,t turning over any faster than a 4 - stroke , just firing on every T.D.C. instead of every second one . Happy Spanners .

[@keithammleter3824]

This video should be retitled "Unusual successful engines". There is nothing strange about a modified VW engine, built in large numbers. There is nothing strange about the Lanz Bulldog - hot bulb semi-diesel engines were once very common, from various manufacturers. The video refers to the Commer Knocker as supercharged - this is an incorrect use of the term. 2-stroke engines, unless loop-scavenged like a lawnmower or whipper-snipper (which are VERY fuel inefficient and burn oil), cannot suck in air. Therefore the air has to be driven in by a fan or air pump. Supercharging is the forcing in of air at above atmospheric pressure, which may or may not apply to 2-stroke engines. A really strange engine is the Sarich orbital engine - in fact it is so strange, completely stupid actually, it exists only as a museum exhibit, badly worn after just 10 minutes or so operation.

TonyValdez - Pre-start with a blow-torch to heat the head and then you get 30bhp @ 300rpm. Plup plup plup plup!

[@richardvaughn2705]

The lanz bulldog, as a hot bulb 2 stroke, is capable of idling at 0 rpm. This is because fuel is injected at BDC. So basically with the throttle adjusted so low that the engine cant overcome compression, it bounces back and forth between TDC in each direction (the engine reverses back and forth never making a full rotation). The fuel is injected into the hot bulb (a heated area that both vaporizes the fuel and causes the white oil smoke to start burning) where it combusts from high heat and compression where it shoots through a tiny hole into the cylinder which causes the piston to move. The tiny path between the hot bulb and the cylinder causes restriction which makes the pressure increase rapidly because of the vaporizing and burning oil which causes the entirety of the fuel oil to combust. This allows a hot bulb engine to have the pressures required to burn fuel oil without needing a high compression ratio. The time it takes for the pressure to build in the hot bulb and move into the cylinder means that the engine has to be designed to run at a limited rpm range. A diesel engine is a modern alternative that uses high compression (double that of a gasoline engine) and injects the fuel using high pressure at TDC into the hot compressed air which combusts it. A diesel can be started cold, but a hot bulb engine needs to have the hot bulb heated cherry red for 10 to 30 minites on even a warm day before it will start.

[@Tom-Lahaye]

Square, or twin row engines, as a square is in essence a twin row eninge with two crankshafts, I worked on a Sulzer 12LDA28, which is a 12 cylinder twin crankshaft design, it's a large marine/railway diesel engine and engineers thought 2 crankshafts should handdle the vast amount of torque better than a V configuration with shared cranks or fork and blade rods. The idea in the Ariel square four was to get a more balanced running engine, problem was the air cooling of the rear cylinders however, it works better in a liquid cooled configuration.

[@beany1987]

dieselmupke ye iv seen that these type of engines have cooling issue with being air cooled but as a car engine design and watercooled id like to know why it dont see production version seam to have great power and torque in a non boosted format.

[@Tom-Lahaye]

Probably too expensive to use in a car engine, those need to be cheap to make in the first place, and only for top end cars would they go that way. Only application I know for twin crankshaft engines in cars are the BRM H16 racing engines, which are 2 flat eights on top of each other.

[@brucerogermorgan2388]

A 6-stroke engine was originally built to get around the Otto 4 stroke patents at the end of the 1800's.It introduced an extra cycle of intake and exhaust of fresh air - no fuel or ignition. As soon as the Otto patents expired it was dropped as it had no advantage over a 4 stroke.

[@sicks6six]

Ariel S4 isn't strange, it did have cooling problems due to air flow over the heads of the 2 barrels at the rear,

[@byronknipe9028]

A 6 stroke engine may be constructed by using a 2 cylinder 4 stroke which exhausts into a single cylinder with inlet valve opening at t.d.c. and exhaust valve opening at b.d.c. In effect a "compound" internal combustion engine.

[@beastlybuickv6402]

Glad someone was able to 'splain that! Thanx!😊

[@Baribrotzer]

Or it might be the Crower Six-Stroke - wherein water is injected into the combustion chamber at TDC of an additional cooling cycle, and that water flashing into steam provides a second power stroke. An ingenious idea, but with significant practical difficulties.

Why are you guys trying to make a misleading distinction between blower-scavenged two-stroke diesels and other supercharged engines? If the pressure in the intake manifold is > 1 atm when the intake port opens, it is, BY DEFINITION, supercharged. Whether it's done by necessity (as in a two-stroke diesel) or just for more power output (as in a four-stroke application) doesn't change the technical definition of supercharging. While the creator of this video clearly isn't very knowledgeable, I'm afraid you guys are the ones guilty of "promulgating ignorance" here.

So the succession of three revolutions and two power strokes is: 1st revolution: Gas intake, gas compression, ignition at TDC; => 2nd revolution: Gas power, gas exhaust, injection of distilled water at TDC; => 3rd revolution: Steam power, steam exhaust; (and repeat the whole thing) =>

[@The_sinner_Jim_Whitney]

I bet the Commer Knocker is like a Detroit, and therefore not technically supercharged. The 'superchargers' on 2-stroke Detroits are really only superchargers when adapted for use on 4-stroke engines, as they aren't there to create 'boost'. They're scavenge pumps, since 2-stroke diesels can't suck air or get rid of their spent gases (and therefore can't run) under atmospheric pressure. Not being a knowitall, I just thought it was cool when I learned it and thought I'd share in case someone else might not know.

Patrick Taylor. It most certainly is a rotary engine. Rotary engine = engine block revolving around a stationary crankshaft. Radial engine = crankshaft rotating within a stationary engine block.

Upon further research i stand corrected, so apparently what we commonly call a rotary engine (the wankle engine) is actually a rotar engine?, something about a mistranslation or some such nonsense. Always have seen these types of engines refered to as radial engines, so my mistake.

[@dickietuttle]

The Gnome Rhone, though it is of radial configuration, is a true rotary engine. The pistons are not accelerated up and down in the bores as in a reciprocating engine since the crankshaft is stationary. The Porsche error is inexcusable.
