  A two-stroke engine works like the shutter of a camera; it only makes good power when the shutter is open (normally betw to 12, rpm). THE AMA GAS RULE WAS A WASTE OF PAPER AND, MORE. Design and Simulation of Two-Stroke Engines is a unique hands-on information source. The author, having designed and developed many two-stroke engines, offers practical and empirical assistance to the engine designer on many topics ranging from porting layout, to .

  Such a concept is widely applied to large bore engines, on steady or naval power-plants, where the advantages versus the 4-Stroke cycle in terms of power density and fuel conversion efficiency (in some cases higher than 50%) are well known. In fact, the double cycle frequency allows the designer to either downsize (i.e. reduce the displacement.   Degner had been working with Walter Kaaden from the East German MZ factory, and it was Kaaden who, after working against his will on the Nazi’s V1 and V2 rocket program of WWII, discovered the expansion chamber and its magical powers of essentially supercharging a two-stroke motor. That part of the book alone is incredible, let alone all the.

Welcome to my primer on two strokes. The Vespa P engine is a good example of a by the book rotary valve two stroke. There are only 3 moving parts in the engine's top end: no pushrods, no camshafts, no lifters, nothing you would expect to see in a 4 stroke automobile engine. an accelerated, severe oil test procedure. in which the cylinder head,,temperatures mentioned were very well aligned with our own appreciation of the disaster thresh- old for two-stroke engines.

Summary 2 Stroke Oil Testing By Ken (BIG BIRD) WACO Brotherhood #70 Summary comments oil mixes and carbon formation: These tests were designed to simulate the effects of long-term high engine temperatures on the formation of carbon from the different two-cycle oils tested.

The target temperature was degrees Size: KB. A two-stroke oil engine with three cylinder has a stroke and bore of mm and mm, respectively. The engine was tested against a brake with a torque arm of m. The results taken on a variable speed test are tabulated in Table 2.

Plot curves of torque, brake power (bp) and specific fuel consumption (sfe) against speed given. 2 stroke engine oil—also known as 2 cycle oil— is a type of motor oil which is used in the compression of two stroke engines. The oil needs to be mixed with gasoline and the final result is known as petroil.

This is why most manufacturers dye their oil in. FOR 2-STROKE CYCLE ENGINES. I have an old 2-cycle engine, can I use non-detergent 30 or 40 weight oils, or do I have to use a 2-cycle oil.

Lots of experience and practice shows and knowledge of 70's and 80's two-stroke racing engines is obvious. The book is based on practical know-how and s:   Beyond checking compression, carburetion and ignition, Brad says the single most important test to run on a 2-stroke is a leak-down test.

A 2-stroke engine requires a properly sealed block to run right because it uses the crankcase vacuum created from the rising piston to pull the incoming charge into the crankcase; the downward stroke of the piston pressurizes the charge. I know there are newer books about this subject, but any good ideas they contain surely came from this book years ago.

basics. There is a huge interest in vintage snowmobiles and their “simple” two stroke power plants of yesteryear. There is a wealth of knowledge contained in this manual. Let’s journey back to and read the book that was the two stroke bible of that era. Decades have passed since I hung around with John and Jim.

John and I worked. The Bourke Engine was designed by Russell Bourke in the s, as an improved two stroke engine.

Despite finishing his design and building several working engines, the onset of World War II, lack of test results,[1] and the poor health of his wife compounded to prevent his engine from ever coming successfully to market. Two-stroke engines get the job done with fewer parts and are therefore lighter, which in turn makes the engine more efficient.

Because two-stroke engines are lighter, they are perfect for smaller gasoline engines, such as those used in lawnmowers, chainsaws and even model airplanes and motorcycles. A lot of two-stroke research took place in the diesel engine business. It quickly became obvious that the more fresh air you blew through a cylinder after it had fired, the purer the mix trapped.

A leak down test is fairly simple to perform and can provide tremendous amounts of information about the health of an engine.

I typically like to perform a leak down test on an engine if I’m having trouble jetting the engine consistently, if I’ve bought a used bike with a suspect past history, or when I’m finishing up assembling a new engine.

PATENTS found on the Japanese Patent Office (JPO) have revealed that Kawasaki is looking to the future, with a new design of two-stroke engine that features a host of innovations.

On the apparatus is placed some eleven differing cylinders of a Yamaha moto. And no, you gents that have successfully run Amsoil ator Thisoil ator Thatoil at are not going to change the data sheets I have from motocross days gone by, or the facts in A.

All two-stroke engines burn gasoline and oil at the same time. In the case of lawn mowers, two-stroke oil is mixed with the gasoline before it goes into the tank. Mixing ratios of gas to oil vary, but usually range from (/4-oz. of oil to one gal. of gas) to (/2-oz. of oil to one gal. of gas). This week’s Two-Stroke Tuesday brought to you by Decal Works is all about big-bore 2-stroke projects!
