Philip Hubert Smith (10 April 1906 [1] – 1 November 1969) [2] was a British automotive engineer, author and motoring journalist.. Born in Keighley, Bradford, Smith began his career began as an automotive engineer, his qualifications including being a chartered engineer and memberships of both the IMechE and the SAE.
During the 1930s and 40s, Phil Irving wrote a technical column in Motor Cycling magazine under the pseudonym 'Slide Rule' [11] some of which were later reprinted in book form as Motorcycle Technicalities. Amongst the other books he authored are Tuning For Speed, Motorcycle Engineering and his autobiography, Phil Irving – An Autobiography.
Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts, and thus be cheaper to manufacture and weigh less. In countries and regions with stringent emissions regulation, two-stroke engines have been phased out in ...
That said, these Austrian two-stroke machines aren’t fuel-injected in the same way as your car. Under the hood, most modern engines feature direct injection, where fuel is squirted directly into ...
A stroke is the action of a piston travelling the full length of its cylinder.In a two-stroke engine, one of the two strokes combines primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...
When the transfer is complete, the piston is on the compression stroke but the exhaust port is still open, an unavoidable problem with the two stroke piston port design. To help prevent the piston pushing fresh mixture out the open exhaust port the strong acoustic wave (produced by the combustion) from the expansion chamber is timed to arrive ...
Prior to this time the commercial engines available had been the Lenoir engine from 1860, a non-compression engine which worked on a double-acting two-stroke cycle, but spent half of each stroke drawing gas into the cylinder. The Hugon engine was a slightly improved version, but both were quite inefficient (95 and 85 cubic feet of gas per HP ...
The 1954 printing of the book by Harry Ricardo The High-Speed Internal Combustion Engine, and also some patents on sleeve valve production, point out that the available zone for ports in the sleeve depends on the type of sleeve drive and bore/stroke ratio; Ricardo tested successfully the 'open sleeve' concept in some two-stroke, compression ...
